Ecological risk of pesticide residues in the British Columbia environment: 1973-2012.

摘要: An updated ecological risk assessment was conducted to re-evaluate and review the overall of pesticide residues certain aquatic life. The focus impact on offsite non-target, freshwater organisms operational sprays in British Columbia from 1973 until 2012. values quotients for pesticides selected indicator were determined measure effect. When compared with organophosphorus, carbamate, other miscellaneous pesticides, this analysis suggests that historical use persistent highly toxic organochlorine posed, continue pose, a deleterious risk. is both short-term acute long-term sub-acute, chronic toxicity offsite, non-target invertebrates juvenile salmonid fish. Data indicated these were, remain, subjected harmful effects varying degrees. Most vulnerable also are, benthic inhabiting bottom sediments....
