Chlordane & Hexachlorobutadiene Daniel Rikli

Slide Guide!  Chlorodane will always be over here!!!  Hexachlorobutadiene will always be over here!!!

Composition and reactivity  Formula: C 10 H 6 Cl 8  Reacts with strong oxidizers and alkaline reagents  Breaks down into toxic gas when heated  Formula: C 4 Cl 6  Reaction depends on heat and temperature

Physical Characteristics  Amber colored  Unstable in weak alkali  Stable, though, in acid and alkaline conditions  Chlorine like odor  Smells like turpentine  Not found naturally in the environment

Mode of entry  Ingestion of high in fat meat products ITS FAT SOLUABLE  Inhalation  Breathing  Eating  Drinking

Major Sources  Pest Control!!  Rubber compounds  Solvent  Lubricants  Gyroscopes  Heat transfer liquid  Hydraulic fluid

Toxicity Levels  Banned in the US and can only be used for subterranean bugs  Lowest dose to cause death is mg/kg  Exposure to children shouldn’t exceed 0.3mg/L  Adults: 0.4mg/L

Environmental Effects  Bioaccumulator  Stays in the environment for a long time  Readily breaks down in soil  Can accumulate in fish and shellfish

Health Risk  Nervous system problems  Liver problems  Increased risk of cancer  Not much is known about the effects on humans but mice had nasal irritation and low baby weight  Suspected carcinogen  Liver and kidney damage
