Plastic debris in lakes and reservoirs
Nava, Veronica; Chandra, Sudeep; Aherne, Julian; Alfonso, María B.; Geraldes, Ana Maria; Attermeyer, Katrin; Bao, Roberto; Berger, StellaPlastic debris is thought to be widespread in freshwater ecosystems globally(1). However, a lack of comprehensive and comparable data makes rigorous assessment of its distribution challenging(2,3). Here we present a standardized cross-national survey that assesses the abundance and type of plastic debris (>250 mu m) in freshwater ecosystems. We sample surface waters of 38 lakes and reservoirs, distributed acros...
Plastic debris in freshwater systems worldwide
Nava, Veronica; Aherne, Julian; Alfonso, María B.; Geraldes, Ana Maria; Attermeyer, Katrin; Bao, Roberto; Bartrons, Mireia; Berger, StellaPlastic debris is widespread in freshwater ecosystems, but a rigorous assessment of its global distribution has been hindered by a lack of comprehensive and comparable data. We performed the first standardized global survey of lakes to assess the quantity and type of plastics (>250μm). We included 38 lakes located in 23 different countries distributed across five continents, spanning different environmental gra...
Global patterns and predictors of microplastic occurrence and abundance in lent...
Nava, Veronica; Frezzotti, Maria Luce; Aherne, Julian; Alfonso, María B.; Geraldes, Ana Maria; Attermeyer, Katrin; Bah, Abdou R.; Bao, RobertoThe majority of microplastic research has focused on seawater, with fewer than 4% of microplasticsrelated studies occurring on freshwaters. The limited available information suggests that the abundance of microplastics in freshwaters is often as high or even higher than marine environments. However, comprehensive investigations on occurrence and fate of microplastics in freshwaters are scarce and highly fragmen...
