    Sammanfattning : In this thesis I explore the ecotoxicological responses of aquatic organisms at different hierarchical levels to organic contaminants by means of bioassays. The bioassays use novel endpoints or approaches to elucidate the effects of exposure to contaminants and attempt to give mechanistic explanations that could be used to interpret effects at higher hierarchical scales.

    Sammanfattning : Arsenic exposure, mainly via drinking water and certain food, is a major public health concern because of its association with various types of cancers and other non-cancer adverse health effects. Worldwide, more than one hundred million people are exposed to elevated levels of arsenic on a regular basis. LÄS MER
