The atmospheric deposition of PCBs, DDT, and lindane,governed uptake in terrestrial biota in the Scandinavianpenninsula. Mammalian herbivores and predators as wellas predatory insects contained hig…
Effects of phthalate esters on the locomotor activity of the freshwater amphipodGammarus pulex
The aim of the study was to determine the effects of phthalates on overall locomotor activity of G. pulex and the impact of long term exposure on diel activity.
