“…Though in the current investigation, bioaccumulation and bioconcentration studies was not undertaken, but our OVC and TMR had the lowest significant values in 24hrs exposure suggesting possibly that surviving fish was maximally intoxicated at this period due to maximum bioconcentration and bioaccumulation and AChE inhibition. The effect of certain pesticides on the activity of acetylcholinestrase may lead to decrease mobility in fish [6]. Although the effect of chlorpyrifos-ethyl on acetylcholinestrase is not known, it has been found to inhibit this enzyme in acute toxicity tests of fish exposed to very low concentrations [16].…”

The impact of short-term exposure to waterborne chlorpyrifos-ethyl on Clarias gariepinus was evaluated through changes of selected behavioural parameters. Fish was exposed to 0.64 mg/l, 0.80 mg/l, 0.96 mg/l, 0.12 mg/l, 0.28 mg/l and control for 96h. The parameters measured were Opercular ventilation (OVC), Tail fin movement rate (TMR), Air gulping index (AGI) and Mortality. The main effects of concentration and duration on rates of tail fin movement rate of fish were highly significant (p<0.001). There was significant decrease (p<0.05) in the opercular ventilation of treated fish when compared with control. Also both the main effects of concentration and duration of exposure of chlorpyrifosethyl and the effect of their interactions on AGI were highly significant (p<0.001). Highest mortality was recorded from 1-12hrs period of exposure and the mortality at 12hrs was significantly (P<0.05) higher than the mortality recorded from 24hrs-96hrs periods. The acute toxicity of chlorpyrifos-ethyl elicited dose and duration dependent behavioural changes that led to mortality of fish. Behavioural changes were therefore proven to be more sensitive endpoints than mortality.

“…These responses are consistent with the known mode of action of heavy metals, which were not implicated in the alleged profile of VIL's contamination, and pesticides which are extensively used in the VIL watershed area that is released into aquatic ecosystems (Direction de l'Environement Picardie, unpublished data). Among these pesticides, many substances are known to inhibit AChE activity (Bretaud et al, 2000;Wogram et al, 2001) and/or induce oxidative stress (Kavitha and Venkateswara Rao, 2007) in aquatic organisms whilst organophosphate are also known as catalytic inhibitors of EROD activity (Flammarion et al, 1998b).…”

O cultivo de arroz irrigado no Rio Grande do Sul caracteriza-se pela permanência de lâmina de irrigação sobre o solo, o que ocasiona perdas de agrotóxicos na ocorrência de chuvas; portanto, o adequado manejo de irrigação pode influenciar na redução do transporte destes para o ambiente. O objetivo deste trabalho foi avaliar o efeito de diferentes manejos de irrigação no extravasamento da água e no transporte e persistência de clomazone, thiamethoxam, imidacloprid, trifloxystrobin e propiconazol em lavoura de arroz irrigado. Os tratamentos arranjados em esquema fatorial consistiram nos manejos de irrigação por inundação contínua, intermitente e por banhos (fator A) e pelos agrotóxicos mencionados (fator B). Determinou-se o volume total de água extravasada e a taxa de dissipação e transporte desses agrotóxicos. Devido ao maior armazenamento de água da chuva, quando comparadas com a irrigação contínua, as irrigações intermitente e por banhos proporcionaram diminuição de 53 e 95% do volume de água perdida, resultando, respectivamente, em redução de 49 e 64% na massa total de agrotóxicos transportados para o ambiente, em relação ao total aplicado na lavoura. A massa de agrotóxico transportada não ultrapassou 3% do total aplicado, e as maiores concentrações de agrotóxicos em água ocorreram próximo à sua aplicação. Com base nesses resultados, salienta-se que os manejos de irrigação intermitente e por banhos minimizam o transporte de agrotóxicos para o ambiente.
