Exposure to<unk> /heptachlor and/or its metabolites (oxychlordane, heptachlor epoxide) are risk factors for type-2 diabetes, for lymphoma, for prostate cancer, for obesity, for testicular cancer, for breast cancer. An epidemiological study conducted by the National Cancer Institute reported that higher levels of<unk>  in dust on the floors of homes were associated with higher rates of non-Hodgkin lymphoma in occupants. Breathing<unk>  in indoor air is the main route of exposure for these levels in human tissues. Currently, EPA has defined a concentration of 24 nanogram per cubic meter of air (ng/M3) for<unk>  compounds over a 20-year exposure period as the concentration that will increase the probability of cancer by 1 in 1,000,000 persons. This probability of developing cancer increases to 10 in 1,000,000 persons with an exposure of 100 ng/m3 and 100 in 1,000,000 with an exposure of 1000 ng/m3. The non-cancer health effects of<unk>  compounds, which include diabetes, insulin resistance, migraines, respiratory infections, immune-system activation, anxiety, depression, blurry vision, confusion, intractable seizures as well as permanent neurological damage, probably affects more people than cancer. Trans-nonachlor and oxychlordane in serum of mothers during gestation has been linked with behaviors associated with autism in offspring at age 4-5. The Agency for Toxic Substances and Disease Registry (ATSDR) has defined a concentration of<unk>  compounds of 20 ng/m3 as the Minimal Risk Level (MRLs). ATSDR defines Minimal Risk Level as an estimate of daily human exposure to a dose of a chemical that is likely to be without an appreciable risk of adverse non-cancerous effects over a specific duration of exposure.
