The impact of pesticides on biodiversity։ Part 2

The final effectiveness of chemicals is not so well, both in agriculture and in the anti-epidemic service (Любищев, 1933, 1955; Реймерс, 1990; Небел, 1994 и др.), (Хотько, Ривкус, 1994).

All this can bring to discussion about the ban on the use of stable pesticides, which can serve both environmental health and animal welfare, as well as human health.

Studies in Krasnodar region show that even arsenic spraying in small areas causes poisoning of wild animals. In the Rostov and Krasnodar regions complete use of arsenic preparations cause of 3-4 times reduction of domestic and wild hunting animals due to toxicosis. Where this ineffective method of the fight against rodents is still being used in practice, the loss of birds is inevitable. One of the reasons for the poisoning of wild animals is the grain that is dumped or stored in the fields, with highly toxic organic mercury mixture, granozone and mercury. These poisons cause severe burns on the skin, and if they penetrate the internal organs, they can lead to rapid death.

In recent years, as a result of mass chemical processing with grain in the regions, there has been a decrease  in the number of industrial animals, which is a result of the casual work of workers on toxic substances. This problem can be solved by strengthening the control over pesticides and the grain processed by them, if the grain is sown in time and correctly in the fields (Каган Ю.С. Токцикология фосфорорганических пестицидов и гигиена труда при их использовании. М. Медгиз 1963. 324с.)․ That’s why the decrease of birds notices only after 2-3 days  in areas working with pesticides.

The bodies of small birds were found in the Krasnodar region, in agricultural lands and forest zones. Only deep research has shown that some species have phosphorus-organic compounds in their gastrointestinal tract (Скокова Н.Н., Лобанов В.А. (1974) Птицы и пестициды. - Мат-лы 6 Всес. орнитол. конф.  М.: МГУ. 2: 358-359.). Mostly  poisoning occurs in the late autumn and early spring during the mass use of fertilizers. Animals need mineral nutrition during these seasons․

Cases of toxicosis are not found in the regions where the rules for the use of mineral fertilizers are followed.   In areas where the use of pesticides is controlled in agriculture and forestry, bird poisoning is simply excluded from pesticides.

Amateur hunters, inspectors and foresters can play an important role in protecting wild animals and birds from the harmful effects of pesticides.
