| Résumé : |
Recent television documentaries have highlighted to the general public', in countries ail round the world, the problem of plastic pollution in the oceans. Logically, this plastic pollution can only result from two sources: the transport and breakdown of macro-polymers (by mechanical wear, photochemical and hydrolytic degradation), or from the transport of micro and nano-polymers.
There have been several attempts now to estimate the scale of contributions from paints and coatings to microplastic pollution in the environment (land and water), ranging from 9.6% to 21%.The most recent addition to the literature, however, is a modelling study from Environmental Action' (EA) claiming that paint contributes to 58% of microplastic leakage to the environment.The range of these estimates indicates how difficult it is to make a quantitative assessment. Furthermore, to understand the scale and importance of plastic as a source of marine pollution, it needs to be viewed in comparison to other sources, such as tyres, textiles or plastic packaging, most of which remain to be comprehensively assessed. |
