The biomagnification of certain chemical contaminants through food webs implies a risk for the conservation of the wildlife species affected and problems of food safety and public health

In the last article of Divulgazeral we said that chemical pollution is a serious threat to the environment whose consequences are being underestimated. We discovered that this type of pollution does not understand frontiers, and that it usually goes unnoticed, so that its effects are manifested in silence,...

For instance, if we walk alongside a river and observe...
