Discovering that every tomato, bean, pepper, and potato plant in your vegetable garden has suddenly twisted into curled, fern-like, shoe-string straps overnight is a devastating agricultural emergency. Unlike fungal blights or insect swarms (covered in our garden pest swarms and crop blight outbreaks guide), chemical phytotoxicity strikes across entire garden rows simultaneously with no fungal spores or chewing pests present. The three most common culprits are airborne herbicide spray or vapor drift (from a neighbor's lawn "weed-and-feed" application, municipal roadside spraying, or agricultural field drift of 2,4-D, dicamba, or glyphosate), "killer compost" or horse/cow manure contaminated with persistent pyridine herbicides (aminopyralid, clopyralid, picloram, or quinclorac), or an acute soil chemical spill (gasoline, diesel, heating oil, swimming pool chlorine, or driveway de-icing salt).

When synthetic herbicides or petroleum hydrocarbons hit a food garden, two urgent questions arise immediately: Can you still save the living plants inside the first 30 minutes of exposure, and is it safe for your family to eat vegetables harvested from herbicide-damaged or fuel-contaminated soil? Knowing how to execute an emergency cold-water foliar wash before systemic herbicides absorb through the leaf cuticle, how to run a 10-day Pea/Bean Compost Bioassay to prove whether imported manure is poisoned, and how to detoxify soil using activated biochar, microbial bioremediation, and grass cover-crop rotation protects both your health and next year's food supply.

Ataovy izao izao

  1. If you witness or smell herbicide spray mist drifting onto your garden right now, wash the leaves immediately with a gentle cold-water hose spray for 15 minutes. Synthetic auxin herbicides (2,4-D, dicamba) and glyphosate take 30 minutes to 4 hours to penetrate the waxy leaf cuticle and translocate down to the roots. Rinsing the foliage immediately with clean cold water washes off 60 to 80 percent of unabsorbed droplets before systemic plant death can occur (wearing nitrile gloves, long sleeves, and eye protection while hosing).
  2. STOP eating any fruit, leafy greens, root crops, or herbs from plants showing chemical curl, bleaching, or oil/solvent odors. Synthetic turf herbicides, pre-emergent lawn chemicals, and petroleum spills are not approved for human food-crop residue and translocate directly into developing tomatoes, beans, berries, and leafy greens.
  3. Never till, rototill, or dig contaminated compost or mulched hay deeper into your native garden soil. If you spread bagged compost, municipal green-waste mulch, or horse/cattle manure onto the surface of a bed and your tomatoes and beans started curling at the growing tips 7 days later, stop and scrape the top layer of contaminated mulch/compost back off the bed immediately with a flat shovel. Tilling it into the ground mixes persistent aminopyralid throughout the entire 30-centimeter (12-inch) root zone.
  4. If gasoline, diesel, motor oil, or pool chemicals spilled onto garden soil, dig out the wet soil hotspot immediately into plastic buckets. Do not hose a fresh petroleum or chemical spill into the dirt, which washes toxic BTEX (benzene, toluene, ethylbenzene, xylene) hydrocarbons deep into the root zone and groundwater. Excavate the stained soil plus a 15-centimeter (6-inch) clean margin all the way around.
  5. Take high-resolution dated photographs and freeze 200 grams (7 ounces) of affected leaves and top-soil in double ziplock bags. If commercial agricultural aerial spraying, a lawn-care company, or a commercial bulk compost supplier poisoned your garden or orchard, preserving frozen tissue and soil samples within 48 hours is important for state/national Department of Agriculture pesticide-drift investigation and financial compensation.
  6. If a person or pet was misted by herbicide drift or splashed by concentrate, strip clothing and flush skin/eyes with running water for 15 to 20 minutes. If concentrated herbicide (especially paraquat, diquat, or organophosphates) was inhaled or swallowed, call your local emergency number (911 in the United States and Canada, 112 across the European Union, 999 in the United Kingdom; see laharana vonjy maika) and Poison Control (1-800-222-1222 in the US) immediately.

Danger

Never eat vegetables grown in soil contaminated with Petroleum Fuels (Gasoline, Diesel, Heating Oil, Motor Oil), Creosote Railroad Ties, or Non-Food Lawn Herbicides. Gasoline, diesel, and waste crankcase oil contain carcinogenic benzene and Polycyclic Aromatic Hydrocarbons (PAHs) alongside heavy metals that absorb directly into plant roots, especially root crops (carrots, potatoes, radishes, beets, onions) and oil-rich seeds/fruits (squash, pumpkins, zucchini, sunflowers), and cannot be washed or cooked out of the food. Similarly, persistent pasture/turf herbicides like aminopyralid, picloram, and dicamba concentrate specifically inside the growing meristems and developing fruits of tomatoes, peas, and beans, making the harvest unsafe for consumption and lethal to any future garden bed where those plant scraps are composted.

Decision Tree: Diagnosing Sudden Chemical Distortion vs. Biological Disease

Gardeners frequently mistake herbicide damage for Tomato Mosaic Virus / Curly Top Virus or broad mite feeding (and vice versa). Use this field diagnostic tree to identify the exact chemical class affecting your beds.

Part 1: Diagnostic Field Guide to Herbicide Drift vs. Viral/Insect Look-Alikes

Because synthetic plant growth regulator (PGR) herbicides mimic natural plant hormones (auxins / indole-3-acetic acid) at 1,000 times normal biological intensity, they force plant cells on one side of a stem or leaf vein to elongate uncontrollably, twisting stems into corkscrews and fusing leaf veins together into narrow ribbons.

Visual Symptom Matrix: Identifying the Exact Chemical Class

Chemical Class & Common Active Ingredients Common Source Around Homes & Farms Exact Visual Symptoms on Vegetable Crops Most Sensitive "Indicator" Plants (First to Show Damage) How to Distinguish From Plant Viruses & Broad Mites
Synthetic Auxins / Growth Regulators (Group 4): 2,4-D, Dicamba, Mecoprop (MCPP), MCPA, Triclopyr Suburban "Weed & Feed" lawn fertilizers, dandelion sprays, pasture sprays, and agricultural soybean/corn vapor drift Epinasty (downward twisting of petioles), S-shaped corkscrew stems, cupped/boat-shaped leaves, and "shoe-string / strap" leaves where leaf blades shrink to narrow ribbons with thick, parallel pale veins; cracked callus tissue on lower stems Grapes, tomatoes, peppers, beans, peas, redbud trees, boxelder, roses, and cotton (affected at parts-per-billion vapor levels up to 1 km away) Viruses (Cucumber Mosaic / Curly Top) hit scattered individual plants and cause mottled yellow-green mosaic patches; Herbicide Drift hits 100% of sensitive plants along a windward gradient all in the exact same week
Persistent Pyridine Carboxylic Acids (Group 4 Subgroup): Aminopyralid, Clopyralid, Picloram, Fluroxypyr, Quinclorac Contaminated horse/cattle manure, hay/straw mulch, municipal compost, or commercial bagged topsoil ("Killer Compost") Identical to auxin damage above, concentrated strictly at the newest apical growing crown: tight "fiddlehead fern" curling of top tomato/potato leaves, stunted bushes, and deformed flowers that drop without setting fruit Nightshades (tomatoes, potatoes, eggplants, peppers), Legumes (peas, fava/bush/pole beans, clover), Sunflowers, Lettuce, and Carrots Broad Mites / Cyclamen Mites cause bronzed, brittle, downward-curled top leaves on peppers; inspect under a 20x hand lens for microscopic translucent oval mites and eggs on leaf undersides
EPSPS Inhibitor (Group 9): Glyphosate (Roundup) Driveway/fence-line weed spraying on a windy day Bright canary-yellow chlorosis starting strictly in the very center/newest growing tips (meristems) while older outer leaves stay dark green for days; followed by stunted rosettes ("witches' broom") and slow death over 10 to 21 days All green plants (non-selective), especially young fruit trees, raspberries, tomatoes, and corn Iron or Sulfur Deficiency also causes yellow new top leaves, but iron deficiency leaves the leaf veins bright green in a sharp web pattern, whereas glyphosatedrift bleaches both veins and blade uniformly yellow-white
Photosystem I & Glutamine Synthetase Inhibitors (Groups 22 & 10): Paraquat, Diquat, Glufosinate Agricultural burndown sprays Rapid "acid-splatter" spotting within 12 to 36 hours: wherever a wind-blown droplet landed, a round bleached tan/brown dead spot with a sharp dark ring appears, while unsprayed new leaves growing out 5 days later look completely normal All green broadleaf and grass foliage hit by droplets Fungal Leaf Spots (Septoria / Early Blight) start on lowest leaves and spread in wet weather; contact drift spots appear strictly on the windward top side of leaves overnight

Part 2: First Aid for Plants Hit by Drift (Can They Recover?)

If your garden was hit by airborne spray or vapor drift (not soil-borne contaminated compost), follow this triage protocol to save ornamentals and determine what must be pulled:

1. The First-4-Hour Emergency Water Wash & Activated Charcoal Soil Drench

  • Step 1 (Immediate Foliar Rinse): If you catch a lawn-care truck or farm sprayer drifting mist onto your yard within the first 30 minutes to 4 hours, turn on your garden hose with a gentle shower nozzle and thoroughly rinse the tops and undersides of all leaves with cold tap water for 10 to 15 minutes. Do not use soap (surfactants actually help herbicides penetrate the waxy leaf cuticle faster).
  • Step 2 (Activated Charcoal Soil Barrier for High-Value Perennials): If spray droplets or lawn granules landed on the soil around prized fruit trees, grapevines, roses, or berry bushes, mix Horticultural Activated Charcoal (or fine powdered food-grade activated carbon / fine biochar) into water at a rate of 120 to 240 grams per 4 liters (¼ to ½ pound per gallon) of water and drench the top 5 centimeters (2 inches) of soil around the drip line. Activated carbon has an enormous microscopic surface area (over 1,000 square meters per gram) that physically adsorbs organic herbicide molecules on contact, locking them out of plant roots.

2. Food Safety Rule: Can You Eat Vegetables After Herbicide Drift?

Cooperative extension toxicologists at land-grant universities (including Oregon State University Extension, NC State Extension, and Purdue University) enforce a strict food-safety boundary when home food crops suffer herbicide drift:

  • Annual Vegetables Showing Any Visible Auxin/Glyphosate Distortion (PULL AND DISCARD): If tomato, pepper, bean, pea, lettuce, spinach, kale, squash, or cucumber plants develop twisted stems, strapped leaves, or bleached meristems from herbicide drift, do NOT eat the leaves, roots, or fruits. First, systemic herbicides like 2,4-D, dicamba, and glyphosate translocate directly through the phloem into the developing fruit and seed (where residue levels can exceed legal EPA / Codex Alimentarius Maximum Residue Limits / Tolerances because those chemicals are not registered for mid-season foliar application on fruiting vegetables). Second, lawn "weed-and-feed" products frequently combine 2,4-D and dicamba with non-food systemic neonicotinoid or organophosphate turf insecticides and heavy-metal impurities that have zero food-crop safety clearance.
  • Perennial Fruit Trees, Grapevines, and Berry Canes: Do not cut down a perennial fruit tree, grapevine, or raspberry patch hit by a single mild drift event. Strip off and discard this season's developing fruit, deep-water the tree once a week with 2.5 centimeters (1 inch) of water, and apply a mild balanced organic fertilizer (such as fish emulsion or kelp meal) to help the tree push out clean new leaves. Leave deformed branches attached until next spring so the tree can photosynthesize, then prune out dead tips the following dormant winter; next year's fruit will be safe to eat.

Part 3: "Killer Compost" (Aminopyralid, Clopyralid, and Picloram Contamination)

Over the last fifteen years, thousands of home and market gardens across North America, the United Kingdom, Europe, and Australia have been poisoned not by spray drift, but by bringing home "organic" horse manure, cow manure, baled hay/straw mulch, or commercial bagged compost contaminated with persistent pyridine carboxylic acid herbicides (aminopyralid [Milestone, Forefront, GrazonNext], clopyralid [Stinger, Lontrel], or picloram [Tordon]).

1. How a Pasture Herbicide Survives a Horse's Gut and a 65°C Compost Pile

  1. A hay farmer or cattle rancher sprays a grass pasture with aminopyralid or picloram to kill thistles and broadleaf weeds (grasses are completely immune to pyridine herbicides, so the pasture grass grows lush and green).
  2. The farmer cuts that grass for hay or lets horses and cattle graze it.
  3. Unlike older herbicides that break down inside an animal's digestive tract or during hot composting, aminopyralid and picloram are chemically engineered to resist biological and thermal breakdown:
    • They pass 100 percent intact through the stomach and intestines of horses, cows, and sheep and are excreted in high concentrations in the animal's urine and manure.
    • They survive 65-degree-Celsius (149-degree-Fahrenheit) commercial thermophilic composting for months without breaking down.
  4. When a gardener spreads that aged manure, compost, or hay onto a raised bed, concentrations as low as 1 to 5 parts per billion (ppb), equivalent to 1 drop of water in an Olympic swimming pool, are absorbed by tomato, potato, pepper, pea, and bean roots, causing every new leaf to curl into tight, stunted fists and destroying the bed's productivity for 1 to 4 years.

2. How to Perform the 10-Day "Pea / Bean Bioassay Test" Before Spreading Any Compost or Manure

Never dump a truckload of manure, municipal compost, or farm hay onto your garden beds without testing a small bucket first. Because laboratory GC/MS testing for aminopyralid at 1 part per billion costs $300 to $500 per sample, university extensions recommend the 100% reliable, $1.00 Pea or Bean Bioassay Test:

  1. Mix the Test Soil: Scoop 4 cups of the suspect compost or aged manure from several spots in the pile and mix it 50/50 with 4 cups of clean, plain potting mix or perlite (for hay or straw mulch, soak a handful of chopped hay in 1 liter of warm water for 24 hours and use that brown "hay tea" to water the test pots).
  2. Manomàna vilany andrana 3 sy vilany fanaraha-maso 3:
    • Fill 3 small starter pots with your 50/50 suspect compost mix (label them TEST).
    • Fill 3 identical starter pots with 100 percent clean commercial seed-starting mix (label them CONTROL).
  3. Amboarina 3 Voankazo mitsimoka haingana na tsaramaso kirihitra ao anaty vilany tsirairay: Ny voanjo (Pisum sativum) sy ny tsaramaso (Phaseolus vulgaris) dia saro-pady amin'ny herbicide pyridine hatramin'ny 1 ampahany isaky ny miliara.
  4. Mitombo eo ambanin'ny hazavana mamiratra amin'ny 20°C hatramin'ny 24°C (68°F hatramin'ny 75°F) mandritra ny 10 ka hatramin'ny 14 andro: Andraso mandra-panirin'ny zana-kazo ** andiany faharoa sy fahatelo amin'ny raviny tena trifoliate** (aza tsaraina amin'ny ravin-kazo roa boribory voalohany/cotyledons, izay toa mahazatra foana):
    • ** Raha ny TEST Ny voanjo dia manana ravinkazo fisaka, malalaka, mivelatra mitovy amin'ny CONTROL vilany:** Ny zezika/zezikao dia madio 100% ary azo antoka hiparitaka eny amin'ny zaridainanao.
    • ** Raha ny TEST Ny voanjo/tsaramaso dia mitongilana ny tahony amin'ny raviny voaforitra, miolana, miforitra mafy, na miketrona:** Ny zezika na ny zezikao dia ** POSITIF amin'ny fandotoana herbicide maharitra**. Mandà avy hatrany ny entana ary aza avela hikasika ny tany zaridainanao izany.

3. Fanarenana tsikelikely ny tany raha efa nafangaronao tamin'ny fandrianao ny "compost mpamono olona"

Raha efa namboly zezika voaloto aminopyralids tao amin'ny taninao ianao, TSY hosasana ny rano, ary ny fiandrasana mangina amin'ny tany maina dia mamela ny poizina ho mavitrika mandritra ny 3 ka hatramin'ny 5 taona. Ny herbicides pyridine dia rava saika amin'ny ** micro micro-organisms aerôbika amin'ny tany (bakteria sy actinomycetes).

Araho ity 4-Step Soil Detoxification Protocol ity mba hampihenana ny fotoana fahapotehan'ny tany manomboka amin'ny 4 taona ka hatramin'ny 9 ka hatramin'ny 18 volana:

  • Dingana 1 (Sintoniny sy haroharoany ny voly midadasika rehetra voan'ny aretina): Sintoniny eo am-pandriana avokoa ny voatabia, ovy, tsaramaso, ary voanjo rehetra ary amboho ho fanariam-pako monisipaly. Aza apetraka ao anaty kompostao ny zavamaniry simba amin'ny aminopyralid na avela ho lo ao anaty tany, satria rehefa simba ny tavin-javamaniry, dia mamoaka ny 100 isan-jaton'ny aminopyralida mifoka ao anaty loto izy mba hanapoizina ny vokatra manaraka.
  • Dingana 2 (Ampiharo Karbonina Mavitrika / Biochar amin'ny 0,5 hatramin'ny 1,0 kilao isaky ny metatra toradroa): Miakatra 500 grama hatramin'ny 1 kilao ny biochar amin'ny fambolena tsara na saribao mihetsiketsika isaky ny metatra toradroa (1 hatramin'ny 2 kilao isaky ny 10 metatra toradroa) mankany amin'ny tany voaloto 15 santimetatra (6 santimetatra) ambony. Mamatotra molekiola aminopyralid maimaim-poana amin'ny ranon-tany ny matrice karbônina porous mba hahafahan'ny voly maniry fa ny mikraoba amin'ny tany kosa mandevona tsikelikely ilay zavatra simika mifamatotra.
  • Dingana 3 (Ataovy mafana, mando, ary asiana rivotra mandritra ny fahavaratra ny tany): Matory ny bakteria amin'ny tany rehefa maina ny tany. Ataovy mando ny fandriana voaloto (toy ny sponjy efa nopotehina) ary atodiho ny tany 15 santimetatra (6 inches) ambony miaraka amin'ny garpu zaridaina isaky ny 3 herinandro mandritra ny vanin-taona mafana mba hampiharihary ny herbicide amin'ny photolysis UV tara-masoandro sy bakteria aerôbika.
  • Dingana 4 (Vombolan'ny "Bioremediation" tsy mahazaka: Katsaka, ahitra ary Brassicas): Aza avela hiboridana ny fandriana. Fambolena avy amin'ny Fianakaviana ahitra (Poaceae), izay 100 isan-jato tsy voaaro amin'ny biôlôjika amin'ny aminopyralid sy clopyralid ary ny fakan'ny fibra matevina dia mamoaka siramamy amin'ny fakany (exudates) izay mampiakatra ny bakteria amin'ny tany mihinana herbicide:
    • Ho an'ny fanafoanana ny fako (Aza atao zezika eny ivelan'ny toerana): Famafazana ** ahitra, oats, varimbazaha ririnina, vary orza, na sorghum-sudangrass** matevina eo ambonin'ny farafara, ary avereno ao anaty fandriana iray miaraka amin'ny hamandoana mba hanafaingana ny fahapotehan'ny mikraoba.
    • Vombolin-tsakafo tsy mahazaka / mahazaka AZONAO maniry amin'ny tany voaloto malefaka (Aorian'ny Biochar): Katsaka mamy (Zea mays) sy Brassicas / Cole Crops (**broccoli, laisoa, chouliflower, kale, collards, voantsinapy, Bruxelles tsimoka, ary radish avo lenta ho an'ny fandeferana voajanahary avo lenta **) fiarovana ara-tsakafo hentitra, mamboly ahitra tsy hohanina mandritra ny vanim-potoana iray manontolo mandra-pahadio ny Pea Bioassay 10 andro dia azo antoka indrindra).

Part 4: Remediating Acute Soil Spills (Gasoline, Diesel, Oil, Salt, and Pool Chlorine)

What if a lawnmower fuel can tips over, a home heating-oil tank leaks, a car radiator dumps ethylene glycol, a saltwater swimming pool backwashes, or winter snowplows pile road salt into your vegetable bed? Match the exact spill to the correct soil chemistry remediation:

Soil Contaminant Spilled Primary Toxic Hazard Immediate Physical Excavation Rule Chemical / Biological Soil Remediation Protocol
Gasoline, Diesel, Kerosene, or Home Heating Oil Volatile BTEX (benzene, toluene, ethylbenzene, xylene) and persistent PAHs (polycyclic aromatic hydrocarbons) Excavate wet/smelly soil immediately into heavy contractor bags for Hazmat disposal (never hose fuel deeper into dirt) For residual trace odors after digging out the hotspot: mix in 30% mature compost + high-nitrogen blood meal / alfalfa meal + activated biochar, keep moist, and aerate weekly so native Pseudomonas hydrocarbon-oxidizing bacteria digest residual light hydrocarbons; do not grow food in that spot for at least 1 to 2 years (see heating oil spill)
Used Motor Oil, Hydraulic Fluid, or Gear Oil Contains heavy metals (lead, cadmium, chromium, zinc, barium) plus high-molecular-weight carcinogenic PAHs that microbes cannot destroy Mandatory total excavation: Dig out 100% of stained soil plus a 15 cm (6 in) clean margin and replace with clean imported soil Bioremediation cannot destroy heavy metals. If a bed is heavily contaminated with waste motor oil or lead paint chips, cap the ground with heavy geotextile landscape fabric and build a 35-cm (14-inch) tall raised bed filled with 100% clean imported soil
Sodium Chloride (Winter Driveway Road Salt or Softener Brine) Sodium (\(\text{Na}^+\)) ions destroy clay soil structure (turning dirt into concrete) and create osmotic drought that burns roots Scrape off any visible solid salt crust on the surface with a flat shovel Apply Agricultural Gypsum (Calcium Sulfate, \(\text{CaSO}_4 \cdot 2\text{H}_2\text{O}\)) at 250 grams per square meter (5 lbs per 100 sq ft) and leach deeply with 10 to 15 cm (4 to 6 inches) of fresh water. The Calcium (\(\text{Ca}^{2+}\)) ions knock the toxic Sodium (\(\text{Na}^+\)) ions off clay particles so the water flushes the sodium down below the root zone
Swimming Pool Water (Chlorine / Bromine / Saltwater Pool Overflow) Free chlorine (\(\text{HOCl}\)) scorches foliage on contact; saltwater pools add sodium chloride Rinse plant leaves immediately with fresh tap water; leach the bed with 5 cm (2 in) of fresh water Chlorine gas/hypochlorite dissipates rapidly in sunlight and organic soil within 24 to 48 hours (leaves zero long-term toxic residue once leached); add 5 cm of fresh compost to restore beneficial soil microbes
Automotive Antifreeze (Ethylene Glycol) Sweet-tasting liquid that causes rapidly fatal kidney failure in dogs, cats, wildlife, and children if licked from puddles Esory avy hatrany ny biby fiompy; kobano miaraka amin'ny fako/fasika ny fotaka ary alamino tany mando Ny ethylène glycol dia levona anaty rano ary biodegrade tanteraka amin'ny alàlan'ny bakteria ao anatin'ny 10 ka hatramin'ny 28 andro amin'ny tany aerôbika mafana; sasao tsara amin'ny rano ny faritra sisa tavela ary tazomy ny biby fiompy mandritra ny 3 herinandro

Why did only my tomatoes, potatoes, and pole beans curl up and die while my sweet corn, onions, cabbage, and strawberries in the exact same raised bed look 100 percent healthy?

That specific pattern, where **nightshades (tomatoes, potatoes, peppers) and legumes (beans, peas) are severely twisted and stunted while corn, onions, brassicas (cabbage, kale, broccoli), and strawberries next to them grow completely normally**, is the textbook fingerprint of **aminopyralid or clopyralid ("Killer Compost") contamination**. Pyridine herbicides are selective broadleaf hormones designed to kill thistles, clover, and nightshades in grass pastures without harming grasses (like corn) or brassicas. It proves the poison came from **imported compost, aged horse/cow manure, or hay/straw mulch** added to the bed rather than a non-selective spray like Roundup.

Is it safe to use lawn grass clippings as mulch around my vegetable garden?

**Only if you are 100 percent certain the lawn has NOT been treated with any "Weed-and-Feed" fertilizer or broadleaf herbicide spray within the past 6 to 12 months.** While older lawn herbicides like 2,4-D and dicamba break down on grass blades after 3 or 4 mowings (roughly 4 to 6 weeks), many modern professional lawn-care sprays and crabgrass killers contain **clopyralid, quinclorac, or prodiamine**, which remain active inside cut grass clippings for **an entire year** and will deform or kill your tomatoes, peppers, and beans the moment the grass mulch gets watered.

If I build new raised wooden garden beds, which types of treated lumber or railroad ties will poison my vegetable soil?

**Never use three specific materials around food gardens:** 1. **Fatorana lalamby karakaraina amin'ny kreosote (mpatory amin'ny lalamby) na andrin-jiro:** Ampidiro ao anaty tany mandritra ny am-polony taona maro ny hydrocarbons polycyclic aromatic carcinogenic (PAHs) sy phenols. 2. **Ny hazo indostrialy tsaboina amin'ny pentachlorophenol:** Misy phenols misy chlorine misy poizina sy loto dioxine. 3. **Pre-2004 Chromated Copper Arsenate (CCA) green pressure-treated lumber** (or salvaged old deck wood): Leaches inorganic **arsenic** and hexavalent chromium into soil. Mifanohitra amin'izany kosa, ny hazo vita amin'ny tsindry amin'ny trano maoderina amidy hatramin'ny taona 2004, misy soratra **ACQ (Alkaline Copper Quaternary)** na **MCA / CA-C (Micronized Copper Azole)**, dia misy arsenika aotra sy chromium aotra** (mampiasa varahina sy fungicide organika ankatoavina ho an'ny fambolena sy fiompiana) ary heverina ho azo antoka ho an'ny fambolen-kazo ao anaty rindrina, indrindra raha toa ka azo antoka ho an'ny rindrina atsangana. polyethylene dobo Liner na dimple membrane.
