Karelian larids under the conditions of global contamination of waters with organochlorines

Resumo

The influence of chlorinated pesticides (DDE and lindane) on Karelian larids has been investigated. Data on the content of pollutants in eggs of the investigated bird species have been obtained by gas chromatography. These data show that the level of anthropogenic contamination is statistically significant, but in general low. This is related with the restriction of these pesticides in modern agriculture and the total decrease in agriculture activity in the northern parts of the country.
