In surface waters, photodegradation is a major abiotic removal pathway of the neurotoxin monomethylmercury (MMHg), acting as key control on amounts MMHg available for biological uptake. Different environmental factors can alter rate photodegradation. However, our understanding how pathways in complex matrixes along land-to-ocean aquatic continuum respond to changes salinity, dissolved organic carbon (DOC) concentration and matter (DOM) composition incomplete. set laboratory experiments combining several artificial natural we demonstrate that interplay DOC concentration, DOM composition, salinity affects MMHg. The presence was found facilitate photodegradation, but degradation rates were not altered by varying concentrations over two orders magnitude. We have stronger effect than concentration. at high levels, where most UV radiation lost within first cm reaction vessels, lower observed. When moving from terrestrially influenced characterized degree humification, towards marine conditions with protein-rich pool, increased. contrast, had stabilizing Hence, especially systems low salt concentrations, either or impact

Dissolved organic matter (DOM) is the primary precursor of disinfection products (DBPs) during chlorination. However, compositional characteristics DOM transformation chlorination process in different source waters and its relationship to cytotoxicity remain understudied. Here, we used high-resolution mass spectrometry evaluate chlorination-induced molecular-level changes derived from surface water sources. We correlated components with profiles selected DBPs using new alternative methods predictive toxicological assessments. Our findings indicate a selective natural tendency for lignin protein conversion manual process. The reactivity bioactive compounds decreased order > tannin or ConAC. mainly attributed lignin- protein-like within CHO CHNO groups. Additionally, mitochondrial damage highly sensitive indicator DOM-induced cytotoxicity. toxicity revealed 37 common toxicity-driving characterized by low mass, medium H/C ratio, O/C reduction state, hydrophobicity. highlight need exploit health effects provide substantial experimental evidence necessity remove potential toxicants.
