摘要

The use of nanopartides in consumer products, for example, cosmetics, sunscreens, and electrical devices, has increased tremendously over the past decade despite insufficient knowledge about their effects on human health and ecosystem function. Moreover, the amount of plastic waste products that enter natural ecosystems, such as oceans and lakes, is increasing, and degradation of the disposed plastics produces smaller particles toward the nano scale. Therefore, it is of utmost importance to gain knowledge about how plastic nanopartides enter and affect living organisms. Here we have administered 24 and 27 nm polystyrene nanopartides to fish through an aquatic food chain, from algae through Daphnia, and studied the effects on behavior and metabolism. We found severe effects on feeding and shoaling behavior as well as metabolism of the fish; hence, we condude that polystyrene nanopartides have severe effects on both behavior and metabolism in fish and that commonly used nanosized partides may have considerable effects on natural systems and ecosystem services derived from them.
