different pieces in the dark. But in sunlight, more compounds were released, ranging from 5,000 to 15,000 dissolved compounds, which equates to 1.1-fold to 50fold increases over the number of compounds released in the dark. Of the approximately 9,000 molecules generated by the pure polymer when exposed to sunlight, only about a quarter overlapped with those from the bags. Based on these results, the researchers say that sunlight’s reactions
with solid plastics can transform them into a plethora of water-soluble compounds whose levels and identities vary, depending on the additives used.
