Analysis of pesticides during different seasons for pesticidal contamination in water samples of Tighra reservoir was carried out on gas chromatograph-electron capture detector with capillary columns following multiresidual analytical technique. Organochlorine pesticides, viz., hexachlorobenzene (HCB), alpha-benzene hexachloride (BHC), beta-BHC, γ-BHC, heptachlor, aldrin, alpha-endosulfan, beta-endosulfan, p,p-DDE, dieldrin, o,p-dichlorodiphenyldichloroethane (DDD), p,p-DDD, p,p-dichlorodiphenyltrichloroethane (DDT), and endrin, and organophosphorus pesticides, viz., choloropyrifos, methyl parathion, diazion, dicholorovos, ethion, malathion, and parathion, were detected in water samples during different seasons. However, the pesticide concentration varied during different seasons at different sites. The prominent reason of contamination is the use of pesticides (both organochlorine and organophosphorus) in the agricultural fields near Tighra reservoir. On the basis of our observations, more extensive monitoring studies need to be carried out, covering all wetlands of Madhya Pradesh to enforce the policies for the restricted application of pesticides in agricultural fields adjacent to wetlands.

“…There was a general shift to the more potent dichlorvos‐based treatment solution (Nuvan, Ciba Geigy; legal medicine for fish in Norway 1988–97) in the late 1980s (Samuelsen 1987a,b; Grave, Engelstad & Søli 1991a, Grave, Engelstad, Søli & Toverud 1991b). Adverse effects of dichlorvos have also been documented to marine life (Høy, Horsberg, Djupvik, Hagstad, Hektoen & Ringstad 1987; Thain, Matthiesen & Bifield 1990), phytoplankton (Raine, Cooney, Coughlan & Patching 1990), lobster and zooplankton (Cusack & Johnson 1990; McHenery, Saward & Seaton 1991) and invertebrate communities (Murison, Moore, McHenery, Robertson & Davies 1997). In the late 1990s, synthetic varieties of the active ingredients of pyrethrum, also known as pyrethroids, have been commercialized as water‐based bath treatments.…”

Motile salmon lice Lepeophtheirus salmonis were successfully removed by an oil-based pyrethrum treatment mixture. The experiments described here are all based on skin exposure of the salmon Salmo salar L. The in-cage method, in which salmon would delouse themselves by jumping through a layer of treatment mixture, gave up to 86.9% delousing effect under low levels of solar radiation (October). However, at higher levels of radiation (May), the comparable effect decreased to 31.8%. Studies of exposure time vs. delousing effect showed no difference between 2-s and 10-s exposure and gave an overall delousing effect of 89.5%. Individual delousing procedures have thus been developed with a 4-to 6-s dip in the pyrethrum treatment mixture. A commercial method is described based on commercial Py-Sal 25 mixed with an anaesthetic bath before a vaccination or sorting operation. The overall delousing ef®ciency with this large-scale method was 85%. This is the method now used in commercial delousing with pyrethrum as the active component.
