Épandage agricole des biosolides municipaux : contenu en métaux et en PBDE du lait de vache

The impact of land application of biosolids (treated municipal sewage sludge) on dairy milk quality was measured in real farm operating conditions where biosolids were applied in accordance with the regulatory framework prescribed in the province of Quebec (Canada). The milk from 14 farms receiving...
