  • First Aid: EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.; SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.; INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. IMMEDIATELY call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop.

  • Toxicity Summary: Heptachlor epoxide is a central nervous system stimulant. It non-competitively blocks neurotransmitter action at gamma-amino butyric acid receptors, resulting in overstimulation of the nervous system. Heptachlor epoxide is also believed to exert carcinogenic effects by activating key kinases in signalling pathways and inhibiting apoptosis.

  • Environmental Bioconcentration: The bioconcentration of heptachlor epoxide in freshwater clam (Corbicula manilensis) fat was 2330 as determined in a 72 day experiment(1). In fathead minnows the BCF was 14400 as determined in a 32 day test in a flow-through aquarium(2). The steady state BCF for sheepshead minnow (Cyprinodon variegatus), pinfish (Lagodon rhomboides), mussels (Mytilus edulis), and oyster (Crassostrea virginica) is 4500, 2900, 1700, and 851, respectively(3). In a 33 day model ecosystem, the BCF was 4900 in fish (Gambusia), 66000 in snail (Physa), and 1600 in alga (Oedogonium)(6). Based on the log octanol/water partition coefficient of 5.40(4), one would estimate a BCF of 7500 in fish using a recommended regression equation(5,SRC). Source: Hazardous Substances Data Bank (HSDB)

  • Environmental Fate: TERRESTRIAL FATE: Heptachlor epoxide adsorbs strongly to soil and is extemely resistant to biodegradation. Monitoring studies reveal that it persists for many years in soil and does not appear to leach significantly into the lower soil layers. On the soil surface, heptachlor epoxide may slowly photodegrade, particularly during the summer months (1% per month). Heptachlor epoxide loss from soil in a microagricultural chamber is observed after application, but the rate of loss decreases over the course of a few days. This loss may be due to volatilization or photolysis of the chemical from the surface microlayer. (SRC) Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: If released into water, heptachlor epoxide will adsorb strongly to suspended and bottom sediment. Little biodegradation would be expected and photolysis probably would only be significant in surface waters in the presence of photosensitizers. While slow volatilization of the free molecule (half-life 60 hr from a model river) would be expected, since heptachlor epoxide would be mainly adsorbed to particulate matter, this would not be a primary loss mechanism. No measureable degradation occurred when 10 ppb of heptachlor epoxide was incubated in water of the Little Miami River, a stream receiving domestic, industrial, and agricultural wastes, for 8 wks in sealed jars under sunlight and artificial lights(1). Heptachlor epoxide was very persistant in a model ecosystem, having approximately the same environmental stability as dieldrin(2). Its estimated half-life in the lower Rhine River based on concentration differences between sampling points was 35 days(3). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: ATMOSPHERIC FATE: Based upon the vapor pressure, heptachlor epoxide is expected to exist in both vapor and particulate phases in ambient air. In the atmosphere, vapor phases reactions with photochemically produced hydroxyl radicals may be an important fate process. The rate constant for the vapor-phase reaction of heptachlor epoxide with photochemically produced hydroxyl radicals has been estimated to be 1.09X10-11 cu cm/molecule-sec at 25 °C, which corresponds to an atmospheric half-life of about 1.5 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(2). Heptachlor epoxide that is associated with particulate matter and aerosols and should be subject to gravitational settling and washout by rain. Contamination of lakes with heptachlor epoxide is believed to occur primarily by wet deposition. Under the proper conditions, heptachlor epoxide bearing dust can be transported for thousands of miles. Photolysis would be expected to occur but there are no data on the extent of heptachlor epoxide degradation in dispersed dust and aerosols(SRC). Source: Hazardous Substances Data Bank (HSDB)
