Bioconcentration and Acute Intoxication of Brazilian Freshwater Fishes by the Methyl Parathion Organophosphate Pesticide
Three species of freshwater Brazilian fishes (pacu, Piaractus mesopotamicus; piavussu, Leporinus macrocephalus, and curimbatá, Prochilodus lineatus) were exposed to an acute dose of 5 ppm methyl parathion organophosphate pesticide. Three to five individuals per species were exposed, one at a time, to 40 liters tap water spiked with Folidol 600. Pesticide concentrations and cholinesterase (ChE) ...
متن کاملThe reproductive toxicity of the organophosphate pesticide 0, 0-dimethyl 0-4-nitrophenyl phosphorothioate (methyl parathion) in the male rat.
Methyl parathion (MP) is a pesticide widely used to protect crops but also illegally used in many countries for spraying homes and businesses to contain insects. The present study was planned to investigate the effects of MP on the male reproductive organs in the rat. Male Wistar rats (13-14 weeks old) were treated with MP and sacrificed as follows. Experiment 1:0 (water vehicle), 1.75, 3.5 or ...
متن کاملParathion and Acute Intoxication. the Importance of Toxicological Analytic Tests
This paper describes the distribution of parathion in blood and various other organs, according to the etiology of the intoxication. As a rule, concentration levels are small, especially in the blood and in the stomach are higher, particularly in cases of suicide. In studies carried out on some patients admitted to hospital with parathion poisoning, entero-hepatic recirculation could have been ...
متن کاملUptake and Bioconcentration of Atrazine by Selected Freshwater Algae
Atrazine bioconcentration and uptake were determined for eight freshwater green algae and diatoms. Atrazine uptake was extremely rapid in all species examined, with nearly 90% of total uptake occurring within the first hour of exposure. Within each division, different species had different bioconcentration capacities, although the accumulation of atrazine was consistently higher in green algae ...
