[Study of penetration to surface waters of pesticides used for protection of greenhouse plants].
Study was made of waste waters from two of the seven state horticultural farms producing vegetables and flowers, located in South-Eastern Poland, samples were taken from collectors carrying waste waters from the greenhouse culture surface, from a ditch and from the Wisłok River where these waste waters are carried. Pesticides were extracted with dichloromethane or petroleum ether. Extracts were evaporated to dryness, whereupon the residues were dissolved in 5 ml of acetone or petroleum ether, and were analysed by gas chromotography (series 104 Pye Unicam gas chromotograph fitted with ECD and TID detectors). The following pesticides were found to penetrate into waste waters: methylpyrimiphos, methidathion, fenitrothion diazinon, methoxychlor, endosulfan, iprodione, vinclozoline, captan, carbendazim (MBC), dichlofluanid. These pesticides were present also in water samples collected from aditch into which waste waters from one of the investigated state farms are carried. There were no pesticides in samples of the Wisłok River waters.
