Commercial chemicals, such as synthetic musks, are of global concern, but data on their occurrence and spatial distribution in aquatic environments of large scale are scarce. Two sampling campaigns were conducted in the present study to measure freely dissolved synthetic musks in freshwaters across China using passive samplers, along with biological coexposure at selected sites. Polycyclic musks (PCMs) dominated synthetic musks, with a detection frequency of 95%. Higher concentrations of PCMs were observed in densely populated Mid, East, and South China compared to less populated regions, indicating the significance of anthropogenic activities for synthetic musks in water. The concentration ratios of galaxolide (HHCB)/tonalide (AHTN) were significantly higher in low-latitude areas than in high-latitude areas from June to September, suggesting that solar radiation played an important role in the degradation of HHCB/AHTN. Significant correlations were found between dissolved concentrations of HHCB and AHTN and their lipid-normalized concentrations in coexposed fish and clam. The estimated hazard quotients for HHCB and AHTN in freshwater fish consumed by humans were less than 0.01 at all sampling sites except the Yangtze River Basin. These results help to understand the environmental fate and ecological risks of synthetic musks on a large geographical scale.

“…Yet beyond the visible signs of a changing Arctic, Indigenous peoples, residents, and newcomers to the Arctic also have to deal with invisible factors impacting health and well-being. The Arctic environment and food are known to be contaminated by a wide range of synthetic organic contaminants, typically via long-range transport from the industrial and urban regions in the temperate regions (North America, Europe and Russia/Asia), including polychlorinated biphenyls (PCBs), per- and polyfluorinated alkyl substances (PFAS), mercury (Hg), lead and emerging contaminants . Several Arctic communities are known to have elevated levels of these contaminants, with known or suspected adverse health impacts .…”

In the Arctic, environment and health are linked in myriad ways. A key emphasis has been on numerous long-lived contaminants in traditional foods, particularly marine mammals, and their well-documented impacts on human, animal and environmental health ("One health approach"). More recent concerns for Indigenous communities focus on the (side) effects of the switch to a modern, processed diet, which is accompanied by a loss of tradition and emerging health impacts. Furthermore, the availability of traditional foods is increasingly threatened by the impacts of climate change, which also causes the emergence and spread of new and old diseases, such as anthrax. Climate change, including thawing permafrost and new forest fire regimes, threatens the built environment and infrastructure. In particular, well-built, planned, and healthy housing is urgently needed, given that much time is spent indoors. Health care, particularly for remote and Indigenous communities, is sparse, and often ignores traditional knowledge and local languages. Indigenous communities in the Arctic continue to suffer from marginalization, resource colonization/extraction, and the impacts of racism. Recent examples of the green energy transition, such as in Norway, continue a pattern of ignoring Indigenous rights and lifestyles. Overall, the connection between environment and health in the Arctic is multifaceted and complex, and investigations and solutions ought to embrace an interdisciplinary and holistic approach toward improving Environmental and Human Health in the region.

“…Since the 1940s, it has been widely used all over the world because of its strong insecticidal efficacy [1]. OCPs can be divided into two categories: one is chlorobenzene and its derivatives, such as dichlorodiphenyltrichloroethane (DDTs), hexachlorocyclohexane (HCHs) and hexachlorobenzene, and the other is organochlorine pesticides based on cyclopentadiene, including chlordane, heptachlor, endosulfan and so on [2][3][4][5][6][7][8][9]. OCPs have the characteristics of low volatility, stable chemical properties, not easy to decompose, long residue period, insoluble in water, soluble in fat and organic solvents, high persistence, bioaccumulation and biotoxicity [10][11][12][13][14][15].…”

Being a famous hometown of vegetables in China, Shouguang City has a long history of vegetable cultivation and is a comprehensive national commodity base for vegetables and fruits. In recent decades, with the expansion of agricultural production, the use of pesticides is increasing. Although organochlorine pesticides (OCPs) have been banned, there are still some residues in soil, groundwater and other media. The study on the migration of the OCPs in soil and groundwater is of great importance for the maintenance of food security. Using methods of hydrogeological survey, laboratory testing and numerical simulation, the spatial distribution characteristics, sources and pollution degree of OCPs in soil and groundwater were analyzed, and the migration and transformation of OCPs in soil–groundwater was dynamically simulated and predicted. The study showed that there were many kinds of OCPs residual in the soil environment. The hexachlorocyclohexane (HCHs) in the topsoil of the study area were mainly due to the use of lindane, and the main source of dichlorodiphenyltrichloroethane (DDTs) in soil was the use of DDTs in history. The contents of HCHs, DDTs and hexachlorobenzene in the topsoil of the study area were at a low level, while the content of endosulfan metabolite endosulfan sulfate was comparatively higher. In recent years, the content of organochlorine pesticides in soil has generally decreased. The indexes of OCPs in groundwater can meet the Standards for Drinking Water quality of China. It was predicted that the HCH pollutants would mainly be distributed in Gucheng Street, Shangkou Town, and its south area where the concentration exceeds 3 ng/L exceeds that of 240 km2. DDT pollutants would mainly be distributed in the east and north of Shouguang City, where the concentration beyond 0.6 ng/L exceeds that of 200 km2. Endosulfan sulfate pollutants would mainly be distributed in the Gucheng Street Office, Shangkou Town, and its south area where the concentration exceeds 1.5 ng/L will exceed that of 150 km2. Hexachlorobenzene (HCB) pollutants would mainly be distributed in Fengcheng in the west of Shouguang City and Nancha River in the northeast, where the concentration exceeds 0.2 ng/L will exceed that of 200 km2. The study enriched the monitoring data of OCPs in agricultural planting areas and provided reference for source analysis, migration prediction, and pollution prevention of OCPs.
