Abstract:Dissolved organic matter (DOM) is likely to coexist with microplastics (MPs) in aquatic environments. However, little is known about the effects of different DOM fractions on the stability and aquatic toxicity of MPs. In this study, we separated humic acid (HA) into three molecular weight (MW) fractions (> 30, 3–30, and < 3 k Da) and examined their effects on the toxicity of polyamide 66 (PA66)-MPs to red tilapia (Oreochromis niloticus). Generally, addition of HA enhanced the stability and thus t… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
