BIOCHEMICAL RESPONSES OF THE DREISSENA POLYMORPHA FROM MUNICIPAL POND TO CAFFEINE, MICROPLASTICS, AND HEATING IN SINGLE AND COMBINED EXPOSURES

Pharmaceuticals have become the aquatic pollutants
of growing concern. Caffeine is one of the most widely distributed in the
surface waters among them. However, the environmentally relevant
models of its effect, which include combined exposures with probable
confounding factors, are unknown. Microplastics are a suspected vector
that influences caffeine bioavailability. The temperature dependence of
response, considering the increase of temperature in surface waters, can
also be anticipated. The aim of this study was to analyze the input of
caffeine, microplastics and elevated temperature into their combined
effect on the zebra mussel Dreissena polymorpha (Pallas, 1771).
