Abstract
Oil spills can result in significant damage to marine estuaries, rivers, lakes, wetlands, and shorelines. Electrospun nanofibers containing biosurfactant (ENFs) can be used to clean oil spills up and protect the environmental biology. Present work aimed to study the side-effects of prepared nanofibers on animal models. Screening of the prepared ECNFs on animals showed that three of them (PVA-5, PEO-1, and PEO-5) are safe to hepatic tissues and liver functions. Furthermore, oxidative stress did not change after using these nanofibers. The PVA-1 nanofibers, however, were found to cause major pathological changes in the liver tissue. In addition, PVA-1 nanofibers were proved to alter the total white blood count and the neutrophil percentages significantly in comparison to the control. In conclusion, PVA-5, PEO-1, and PEO-5 are safe to hepatic tissues and liver functions.

Characterization and health risk assessment of organophosphate esters in indoor dust from urban and rural domestic house and college dormitory in Nanjing, China. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2020; 27:36826-36837. [PMID: 32577965 DOI: 10.1007/s11356-020-09494-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/30/2019] [Accepted: 05/27/2020] [Indexed: 06/11/2023]
Abstract
Indoor dust is an important route of exposure for organophosphate esters (OPEs), which are associated with adverse health effects. In the present study, the pollution occurrence and potential health risks of 13 OPEs in indoor dust from urban homes, college dormitories, and rural homes in Nanjing were investigated. Most OPEs were detected in the tested samples. College dormitories dust samples showed significantly higher OPEs concentrations (132.31-1.61 × 103 ng/g), followed by that in urban homes (31.42-49.84 ng/g) and rural homes (51.19-309.75 ng/g). The Mann-Whitney U test found no significant difference in the total concentrations of OPEs except for some individual OPEs between urban and rural homes. Tris (2-chloroisopropyl) phosphate (TCPP) was the most abundant compound in all tested areas. Spearman correlation coefficients and principal component analysis indicated that OPEs might originate from different sources in three microenvironments. Estimated exposures for adults and children in all indoor dust were below the relevant reference doses. Additionally, TCPP was the primary contributors to the non-carcinogenic risk, ranging from 1.07 × 10-6 to 2.20 × 10-5. Tris (2,3-dibromopropyl) phosphate was the dominant carcinogenic risk contributor in indoor dust, with a range of 1.33 × 10-11 to 8.74 × 10-10. These results suggested that the health risk of OPEs was within acceptable limits in the tested areas.

Abstract
Research on mercury (Hg) in aquatic ecosystems in China has focused mainly on fish, with little research on the base of the food chain and Hg bioaccumulation mechanisms. This paper summarizes research progress pertaining to the characteristics, current status, and trends of Hg accumulation in the aquatic food chain in China, analyzes the effects of human activities on the transmission and accumulation of Hg in aquatic food chains, and assesses their risks to human and ecosystem health. A comparison of fish samples in China between 2000 and 2018 indicates that their total Hg content remains at relatively safe levels. However, because current information is generally insufficient to confirm how anthropogenic activities affect transformation and bioaccumulation in the aqueous environment, Hg isotope studies should be a focus of research on aquatic food webs. Additionally, more attention should be paid to Hg transport and bioaccumulation in the basic food chain by focusing on multi-contaminant joint exposure studies and establishing Hg bio-transport models.
