Microplastics And Marine Life - IAEA
21 Dec 2017 -  As many as 5.25 trillion plastic particles weighing 250 000 tons are floating in the oceans, according to recent estimates. This presents a serious environmental challenge: pollutants already dissolved in seawater can be attached to these plastic fragments, which marine organisms can ingest.
The IAEA earlier this autumn initiated an international research project to use nuclear and isotopic techniques to gain a better understanding of the effect these microplastics have on organisms and to evaluate any additional contamination risks from associated pollutants.
