In the United States, chlordane was used for termite-treatment of approximately 30 million homes until it was banned in Chlordane was banned 10 years earlier for food crops like corn and citrus, and on lawns and domestic gardens. Like other chlorinated cyclodiene insecticides, chlordane is Odor: Slightly pungent, chlorine-like.

Mainly, oral toxicity studies on avian, reptilian, and perhaps amphibian species are needed.

Only lindane and methoxychlor are approved for use on or around livestock. Detectable residues of some chlorinated hydrocarbon insecticides, including BHC, heptachlor, heptachlor epoxide, lindane, and oxychlordane, can be found in fatty tissue after acute or.
Organ toxicity: In clinical studies of acute or chronic exposure to chlordane, the effects most frequently observed are central nervous system effects, liver effects, and blood disorders .
Chronic exposure to chlordane may cause jaundice in humans. Eighty‐six percent of the LC 50 acute toxicity data were less than two orders of magnitude different from the chronic toxicity no‐effect concentration for the same chemicals and species.

Abstract. The acute toxicity (hr median lethal concentrations (LC50s) of ten chlorinated isomers of benzene, phenol, ethane, and ethylene to the American flagfish (Jordanella floridae) were determined in both static and flowthrough c toxicity to embryo-larval fish was also estimated from hatching success and post-hatch survival as well as fry growth rates and by: In a study reported by Velsicol (the manufacturer of chlordane), it was found that when monkeys were exposed for 90 days to air chlordane levels of micrograms per cubic meter of air, they were more likely to develop a condition known as leukopenia (9), which means their disease fighting white blood cells dropped to a dangerously low number.
Toxicity testing Aquatic systems reflects perturbations in the environment. So fish and invertebrates can often be used to indicate the health of an aquatic system because chemicals can accumulate in invertebrates from the water and sediment and in fish from water, sediment, and the food chain.
Fish acute toxicity syndrome (FATS) is a set of common chemical and functional responses in fish resulting from a short-term, acute exposure to a lethal concentration of a toxicant, a chemical or material that can produce an unfavorable effect in a living organism.
By definition, modes of action are characterized by FATS because the combination of common responses that represent each fish Specialty: Veterinary medicine.

Introduction Chlordane is a mixture of structurally related cyclodienes (primarily octachloro-tetrahydro-methanoindanes) that was widely used as a broad-spectrum organochlorine-pesticide from to (U.S.
EPA ). chronic toxicity of the wastewater is proposed. This would allow the validation of the mg F/L value as a water quality target under local conditions (water temperature, pH, salinity and hardness). Furthermore, more toxicity tests with the wastewater should be conducted to.
chronic toxicity Rats fed from very low to high doses of methoxychlor (10 to 2, mg/kg) for two years had growth retardation above ppm but no tissue damage from the methoxychlor.
Human volunteers taking oral doses of to mg/kg/day for six weeks had no adverse effects measured by routine enzyme (biochemical) or (blood) hematologic.
chlordane concentrations was % relative to nominal concen-trations. Previous studies (Hall et al. ) reported relatively rapid (,48 h) sorption of chlordane to surfaces of test vessels.
The immunoassay responds to aqueous chlordane and should be indicative of aqueous exposure. Reported h LC50 values were not corrected for recovery. the acute toxicity of Dichlorvos to sheep head min-now, Atlantic silverside, striped mullet and Atlantic herring has been reported The lowest day LC 50 was mg/L in Atlantic herring (McHenery et al., ).The long-term toxicity of Dichlorvos has been reported in toxicity studies of early life stage from fer.
The effects of independently altering chloride, calcium, and dissolved organic carbon (DOC) on the toxicity of silver (presented as AgNO 3) were compared between rainbow trout (Oncorhynchus mykiss) and fathead minnows (Pimephales promelas).The 96‐h median lethal concentration (LC50) toxicity tests for both species were performed under the same conditions, within the same containers.
