Abstract(s)
The 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 fragmented, partly because detection and identification of microplastic particles is
rather complex. In addition, up to now, harmonized and standardized protocols for the sampling and
analysis of microplastics in freshwaters do not exist, and studies with different research aims and
hypotheses often report unstandardized results, making comparison among studies difficult. In the
present study, we performed the first global standardized sampling and analysis effort to investigate
the occurrence and distribution of microplastics in surface water of lakes and reservoirs with different
anthropogenic impacts. Participants aim to collect water samples of freshwater systems with different
features (e.g., area, depth, thermal behavior, watershed), following a common protocol. This
18
establishes the collection of samples by horizontal trawling of a plankton net and, after treatment
with hydrogen peroxide, the polymer identification through micro-Raman spectroscopy. This GLEON
project will allow obtaining comparable data about microplastic contamination in different freshwater
systems around the globe. With this global dataset, our goals are to determine whether a relationship
exists between the abundance of microplastics and the waterbody/watershed attributes and
understand which factors are likely to influence the occurrence of microplastics in surface water of
lentic systems.
