Partitioning, bioavailability, and toxicity of the pyrethroid insecticide cypermethrin in sediments.
The partitioning, bioavailability, and toxicity of cypermethrin in water-sediment systems was investigated. Cypermethrin adsorbed extensively and rapidly, with an overall mean organic carbon (OC) adsorption partition coefficient (Koc) of 350,000, and approximately 99% adsorption occurred within 24 h. Bioavailability was measured via body burdens of Daphnia magna and Chironomus tentans. Mean bio...
متن کاملSub-Chronic Toxicity Study of Alpha-Cypermethrin in Rats
Alpha-cypermethrin (?-CP) a synthetic pyrethroid (type-II) insecticide, dissolved in dimethyl sulfoxide (DMSO-1ml) given consecutive daily orally for 60 days at 1/10LD50 (14.5mg/kg). The animals were sacrificed on day 61st. Biochemicals, cytochromeP450, b5 contents in liver along with antioxidant status, tissue residual concentration, and brain GABA level were studied. It increased the serum am...
متن کاملPyrethroid insecticides and sediment toxicity in urban creeks from California and Tennessee.
Pyrethroid pesticides have replaced organophosphates for many urban applications, including structural pest control, landscape maintenance, and residential home and garden use. This study was intended to determine if pyrethroids are detectable and widespread in diverse urban systems and if concentrations are high enough to cause associated aquatic toxicity. Urban creeks in California and Tennes...
متن کاملBiota-sediment accumulation factor and concentration of heavy metals (Hg, Cd, As, Ni, Pb and Cu) in sediments and tissues of Chiton lamyi (Mollusca: Polyplacophora: Chitonidae) in Chabahar Bay, Iran
Heavy metals and some organic substances which are drained into the aquatic environments and cannot be decomposed or eliminated will sink into sediments or find their way into different levels of food chain. Bioaccumulation is the process of continuous deposition and aggregation of these substances into the body tissue of living organisms. Mollusks are remarkably appropriate to be used as bio-i...
