The production of face towels is growing at an annual rate of about 4% in China, reaching 1.13 million tons by 2021. Phthalates (PAEs) are widely used in textiles, and face towels, as an important household textile, may expose people to PAEs via the skin, further leading to health risks. We collected new face towels and analyzed the distribution characterization of PAEs in them. The changes of PAEs were explored in a face towel use experiment and a simulated laundry experiment. Based on the use of face towels by 24 volunteers, we calculated the estimated daily intake (EDI) and comprehensively assessed the hazard quotient (HQ), hazard index (HI), and dermal cancer risk (DCR) of PAEs exposure in the population. PAEs were present in new face towels at total concentrations of

Organophosphate esters (OPEs) are frequently used as flame retardants and plasticizers in various commercial products. While initially considered as substitutes for brominated flame retardants, they have faced restrictions in some countries due to their toxic effects on organisms. We collected 37 soil and crop samples in 20 cities along the coast of South China, and OPEs were detected in all of them. Meanwhile, we studied the contamination and potential human health risks of OPEs. In soil samples, the combined concentrations of eight OPEs varied between 74.7 and 410 ng/g, averaging at 255 ng/g. Meanwhile, in plant samples, the collective concentrations of eight OPEs ranged from 202 to 751 ng/g, with an average concentration of 381 ng/g. TDCIPP, TCPP, TCEP, and ToCP were the main OPE compounds in both plant and soil samples. Within the study area, the contaminants showed different spatial distributions. Notably, higher OPEs were found in coastal agricultural soils in Guangdong Province and crops in the Guangxi Zhuang Autonomous Region. The results of an ecological risk assessment show that the farmland soil along the southern coast of China is at high or medium ecological risk. The average non-carcinogenic risk and the carcinogenic risk of OPEs in soil through ingestion and dermal exposure routes are within acceptable levels. Meanwhile, this study found that the dietary intake of OPEs through food is relatively low, but twice as high as other studies, requiring serious attention. The research findings suggest that the human risk assessment indicates potential adverse effects on human health due to OPEs in the soil–plant system along the coast of South China. This study provides a crucial foundation for managing safety risks in agricultural operations involving OPEs.

Pesticide residues and their accumulation in marine environments pose potential threats to the ecosystem balance and human health. Assessment of pesticide residue levels and ecological risks in marine waters is insufficient. Therefore, we conducted a quantitative analysis of four different categories of pesticides in the surface waters of the Bohai Sea and Yellow Sea in China. A comprehensive ecological risk assessment framework was constructed based on the importance of ecosystem services, utilizing the risk quotient (RQ) and entropy weighting methods to evaluate the multi-pesticide ecological risks in the study area. Thirteen pesticides were detected in the surface waters, with total concentration levels ranging from 8.18 to 80.60 ng/L, and the herbicide Atrazine and insecticide Imidacloprid were found at the highest levels. Concentration levels were higher in the Bohai Sea than in the Yellow Sea, and the highest area was mainly located on the coast of Shandong Province, China. The ecological risk of multi-pesticide pollution was the highest in the coastal regions of Shandong and was associated with Atrazine and Acetamiprid. Source analysis suggested that triazine herbicide and neonicotinoid insecticides are predominantly land-sourced, whereas sulfonylurea herbicides are primarily atmospheric. This study provides valuable support for formulating relevant environmental protection policies and measures.

The residues and risks of heavy metals in the environment and organisms have attracted great concern for many years. However, the information on their long-term spatiotemporal trends and potential health and ecological risks are scarce. In this study, a total of 1815 seawater samples, 451 sediment samples, and 54 seafood samples were collected in Xiangshan Bay, China, between 2011 and 2016. The residue, distribution, seasonal variation, and potential health risks of seven heavy metals in seawater, sediment, and seafood were evaluated. Dissolved Zn (mean = 16.8 μg L −1 ) and Cu (mean = 3.4 μg L −1 ) concentrations were high in seawater. Sediments were mainly contaminated by Zn (mean = 120.8 mg kg −1 ) and Cr (mean = 81.7 mg kg −1 ). The highest levels of Cu and Zn were observed in Ostreidae with the concentrations of 84.3 and 99.0 mg kg −1 , respectively. The Kendall test indicated that only As, Cu, Cd, and Hg showed decreasing trends in seawater with time and no significant temporal trends were identified for heavy metals in sediment between 2011 and 2016. Only As may pose non-carcinogenic risks to both adults and children in some seafood. These data provide a reliable reference for government to use in developing reasonable and scientific regulations on the ecological and food safety of this area.

This study investigated the levels and composition of 16 priority polycyclic aromatic hydrocarbons (PAHs) in marine organisms from South China Sea and assessed their potential health risks. The results revealed that the pollution levels of total PAHs ranged from 3.56 to 392.21 ng/g dw. Notably, 4-ring PAHs constituted the predominant fraction (58.02 %) of the total PAHs, with pyrene being the most abundant congener across all species. Intriguingly, our findings suggested that consuming these organisms might pose a low non-cancer hazard. Nonetheless, benzo[ a ]pyrene was detected in most species, with levels ranging from non-detectable to 11.24 ng/g dw. The individual lifetime cancer risk levels associated with seafood consumption in studied regions ranged from 1.10 × 10 −5 to 1.52 × 10 −5 , highlighting a potential cancer risk that warrants special attention. These findings emphasize the need to prioritize carcinogenic compounds over total PAHs and underscore the importance of continuous monitoring of PAH pollution in seafood.

Organic ultraviolet filters (OUVFs) are extensively incorporated into both cosmetic items and industrial products and have been commonly found in water ecosystems. This study aims to examine the environmental levels, sources, ecological and human health risks of 14 commonly used OUVFs both in coastal water and beach deposit samples collected from the nearshore regions of Hainan Island and the South China Sea. This is first study highlighting the contamination of OUVFs in Hainan Island and utilizing economic and tourism data to confirm the potential source of OUVF pollution in costal aquatic and coastal ecosystem. Along the coastal tourist regions of Hainan Island, the median concentrations in coastal waters and beach deposits of these OUVFs fall within the range from 1.2 to 53.2 ng/L and 0.2–17.0 ng/g dw, respectively. In coastal water and beach deposit, the concentration of BP-3 was the highest, with median concentrations of 53.2 ng/L and 17.0 ng/g dw, respectively. Regarding human health risks, the daily intake of all 14 OUVFs through swimming was found to be 40–48 ng/kg/day. Ecological risk assessment indicates that BP-3 presents a medium risk for marine microalgae with a concurrent low risk for corals. The correlation analysis underscores a substantial interrelation of OUVFs in both coastal waters and beach deposits with various economic indicators, including annual rainfall, overnight tourists, total hotel rooms (unit), room occupancy rate, and sewage treatment capacity.

The presence of volatile organic compounds (VOCs) in drinking water has the potential to harm human health and undermine public confidence. Hence, this is the first study to comprehensively investigate concentrations of 25 VOCs in the 146 drinking water treatment plants (DWTPs) in 24 cities across seven major river basins (including the Yangtze River, Yellow River, Haihe River, Songhua River, Liaohe River, Pearl River, and Huaihe River), China. The occurrence, human health, and olfactory risks, as well as removal efficiency of VOCs in DWTPs, were evaluated. The findings revealed that 21 VOCs were detected, with concentrations ranging from not detected to 99.10 μg/L (trichloromethane). The maximum concentrations of trichloroacetaldehyde (54.90 μg/L) and trichloromethane (99.10 μg/L) exceeded China's regulated values (GB 5749–2006/2022). The concentrations of VOCs and water quality parameters showed a strong positive correlation. Human health and olfactory risks assessment indicated that drinking water exposures do not pose carcinogenic (CR < 10 −6 ) and non-carcinogenic (HI < 1) health risks to consumers, nor do olfactory and taste hazards (OHI <1). However, it is worth mentioning that due to the relatively high concentrations of some VOCs (trichloroacetaldehyde, acrolein , and trichloromethane), the health risk posed by them are still a major concern that needs to be addressed. Finally, the removal efficiency of VOCs is low in 146 DWTPs (mean of 12.91%–76.79%). Taken together, adding advanced treatment procedures for the purpose of improving the removal efficiency of pollutants of DWTPs in the future is an urgent priority.

Polycyclic aromatic hydrocarbons (PAHs) have long been globally distributed, and almost worldwide people are exposed to varying degrees of PAHs. Aqueous medium is an important transmission route of PAHs, but the detection of PAHs in aqueous environment has been a challenge. Herein, a magnetic hypercrosslinked polymer microsphere (Fe 3 O 4 @SiO 2 -PS@HCP) was developed for the effective detection of PAHs. Under the effect of multiple factors (hydrophilicity, intermolecular force and molecular volume), Fe 3 O 4 @SiO 2 -PS@HCP shows excellent performance on the enrichment of five PAHs in aqueous environment. Fe 3 O 4 @SiO 2 -PS@HCP was used to capture PAHs in city river of plateau lake. In-depth data analysis showed that factory activities and traffic emissions are the main pollution sources of PAHs. Ecological, carcinogenic and non-carcinogenic risks are almost within the safe range. The carcinogenic and non-carcinogenic risks of PAHs in children are higher than adults, which needs to be taken seriously. This method breaks the dilemma that it is difficult to enrich weakly hydrophilic pollutants in aqueous media, and complements important pathways for tracing sources of pollutants and assessing associated risks. It brings methodological enlightenment into the development of environmental pollution and human health risk assessment methodology.

Micro- and nanoplastics (MNPs) have drawn growing concerns because of their potential adverse effects on aquatic ecosystems. However, limited information is available regarding their concentration and distribution in the actual environment, particularly for nanoplastics (NPs). Herein, forty-eight sampling sites were established across the entire Taihu Lake to comprehensively investigate small MNP (<100 μm) pollution. By pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS), six kinds of MNPs in Taihu Lake, namely polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polystyrene (PS), and polymethyl methacrylate (PMMA) were quantified. Total mass concentrations of the six MNPs in the collected surface water samples ranged from 381 to 1356 μg/L. Specifically, the concentrations of small microplastics (1–100 μm) ranged from 229 to 1182 μg/L, and those of nanoplastics (<1 μm) ranged from 88 to 305 μg/L. The mass concentrations of the six MNPs were as follows: 20.3–635.7 μg/L for PE, 46.6–281.4 μg/L for PP, 81.8–410.6 μg/L for PET, 62.8–445.8 μg/L for PVC,

Synthetic phenolic antioxidants (SPAs) and parabens, particularly the high-molecular-weight (HMW) SPAs and long alkyl chain (LAC) parabens with higher environmental persistence and toxicities, are widely produced and applied worldwide. However, their occurrence and potential risks in aquatic environments remain largely unknown. This work investigated 11 HMW SPAs and 3 LAC parabens in the river and treated industrial wastewater samples along the Yangtze River, the largest river and most important source water in China. For convenience of comparison, 6 short alkyl chain (SAC) parabens were also included. In 15 industrial wastewater treatment plant effluents (effluent-IWTPs) and 34 surface water monitoring sections along the river, 19 out of 20 target compounds were detected with total concentrations (TCs) from 152.5 to 1955.5 ng/L and 141.3 to 1364.9 ng/L in effluent-IWTPs and surface water, respectively. HMW SPAs 1,3,5-tris-[(3,5-di‑tert‑butyl‑4-hydroxyphenyl) methyl]-1,3,5-triazinane-2,4,6-trione (AO3114) and octadecyl 3-(3,5-di‑ tert ‑butyl‑4-hydroxyphenyl) propionate (AO1076) were the dominant ones. HMW SPAs bis(3‑tert‑butyl‑4‑hydroxy-5-methylphenyl) propionate (AO245) and 4,4′-sulfanediylbis(2‑tert‑butyl‑5-methylphenol) (AO-TBM6) and SAC parabens propylparaben (PrP) and butylparaben (BuP) posed medium to high potential ecological risks in 27 surface water monitoring sections. Additionally, AO-TBM6 also exhibited potential health risks in 2 out of 11 drinking water sources. Though the ecotoxicity data are very limited, the ubiquitous presence of the LAC parabens including hexylparaben (HeP) and octylparaben (OcP) in surface water should be of concern since these compounds usually exhibit stronger estrogen potencies than the SAC ones. Finally, kernel density analysis revealed that regulation of industrial discharges is necessary to mitigate the HMW SPA and paraben contamination.

A comprehensive assessment of the heavy metal system in the rehabilitated saline-alkali land holds significant importance, as the in-situ remediation process utilizing amendments substantially alters the initial physicochemical properties of the soil, which could lead to the migration or reactivation of previously stabilized heavy metals. In this context, the present study aims to evaluate the heavy metal content and health risk within the improved saline-alkali soil-plant system. Moreover, a comprehensive evaluation based on the TOPSIS-RSR method is carried out to accurately gauge the soil health status. The findings indicate that the modification process has an impact on the concentrations of heavy metals in the soil and crops, causing either an increase or decrease. However, the level of heavy metal pollution in the improved saline-alkali soil and rape remains within safe limits. The results of the migration of heavy metals after amendment application indicated that the migration of heavy metals in the soil was influenced by the properties of the heavy metals, the composition of the amendment, and leaching. Furthermore, the total non-carcinogenic hazard quotients in the soil and rape were within the safe threshold for all populations. The findings provided novel insights into the status and risk assessment of the pollution of improved saline-alkali soil.

A sensitive and robust multiclass analytical method was established to simultaneously determine 55 antibiotics in aquatic products through liquid chromatography–tandem mass spectrometry. A simple one-step purification process was successfully developed, which combined post-acidic acetonitrile extraction directly by an enhanced matrix removal cartridge. This approach eliminated the need for solvent transition. The established method for 55 antibiotics achieved an excellent linear relationship with R 2 values ≥ 0.9921 in the range of 0.05–200 μg/L. The quantitation limits ranged within 0.04–5.0 μg/kg. Satisfactory recoveries (76.2%–99.7 %) were achieved with the relative standard deviations below 13.9 %. Furthermore, the antibiotic residues in aquatic products were analyzed, and the health and antibiotic resistance risk assessments were conducted. Although the health risks of target antibiotics were acceptable, a resistance risk was observed. Therefore, monitoring antibiotic residue levels in aquatic products requires considerable attention and further research to ensure the quality of marine products and consumer safety.
