Understanding the risks of mercury sulfide nanoparticles in the environment:Formation,presence,and environmental behaviors
文献摘要：
Mercury(Hg)could be microbially methylated to the bioaccumulative neurotoxin methylmercury(MeHg),raising health concerns.Understanding the methylation of various Hg species is thus critical in predicting the MeHg risk.Among the known Hg species,mer-cury sulfide(HgS)is the largest Hg reservoir in the lithosphere and has long been considered to be highly inert.However,with advances in the analytical methods of nanoparticles,HgS nanoparticles(HgS NPs)have recently been detected in various environmental matrices or organisms.Furthermore,pioneering laboratory studies have reported the high bioavailabil-ity of HgS NPs.The formation,presence,and transformation(e.g.,methylation)of HgS NPs are intricately related to several environmental factors,especially dissolved organic matter(DOM).The complexity of the behavior of HgS NPs and the heterogeneity of DOM prevent us from comprehensively understanding and predicting the risk of HgS NPs.To reveal the role of HgS NPs in Hg biogeochemical cycling,research needs should focus on the follow-ing aspects:the formation pathways,the presence,and the environmental behaviors of HgS NPs impacted by the dominant influential factor of DOM.We thus summarized the latest progress in these aspects and proposed future research priorities,e.g.,developing the de-tection techniques of HgS NPs and probing HgS NPs in various matrices,further exploring the interactions between DOM and HgS NPs.Besides,as most of the previous studies were conducted in laboratories,our current knowledge should be further refreshed through field observations,which would help to gain better insights into predicting the Hg risks in natural environment.
