Identifying Microplastics
Tracking microplastic pollution to its sources will usually require identifying the particular plastics and, only then, its likely sources. One of only two public-access databases can be used with the assistance of tech instructions published in Nature.com publication Scientific Data:
“A Raman spectral reference library of potential anthropogenic and biological ocean polymer”
