Summary: Most fish consumption advisories in the U.S. are for mercury, PCBs, and recently PFAS. A survey was conducted to characterize the contamination of mercury, PCBs, and PFAS in fish from U.S. rivers on a national scale. The results showed that all fish fillet samples contained detectable levels of mercury and PCBs, while a high percentage of samples contained PFAS.

Summary: The environmental conditions of groundwater and surface water vary greatly depending on the location, which can affect the physical and chemical properties of nanocomposites and pollutants used in remediation. In this study, magnetic nanocomposite microparticle (MNM) gels were used as sorbents for remediating PCB 126 as a model organic contaminant. The effects of ionic strength, water hardness, and pH on the sorption efficiency of the MNMs for PCB 126 were studied. The results showed that ionic strength and water hardness had minimal effects on the sorption of PCB 126 by MNM gels, while an increased pH resulted in a decrease in binding, likely due to anion-pi interactions.

Summary: The study revealed that the impact of MPs on PCB bioaccumulation is dependent on the pollutant concentration, with MPs significantly increasing PCB accumulation at high concentrations. In contrast, FBPs were found to more effectively enhance PCB bioaccumulation in zebrafish under all scenarios.

Summary: This study reports the first experimental evidence of microplastic-mediated transfer of a key PCB congener into adult sea urchins. The results suggest that even during short-term exposure events, microplastics located on the seafloor may act as vectors of PCB-153 to sea urchins.

Summary: The study found significant differences in PCBs and DDTs concentrations among the six biota species from Qilianyu Island. The levels of PCBs and DDTs in intermediate egret were significantly higher than the other five biota species, likely due to their different feeding and living habits. The study also confirmed that dietary source is an important factor in determining the levels of PCBs and DDTs in biota species, and biomagnification of contaminants occurred in the native species on the island.

Summary: There is an increasing awareness of paints and pigments as a source of by-product PCBs in the environment. This review identified the presence of 149 different PCBs in paint samples, which is more than what has been reported in commercial Aroclor formulations. The study also provides valuable information on the mechanisms of PCB formation in pigments, dyes, and paints, as well as additional classes of pigments that are expected to contain PCBs.

Summary: This study introduces an integrated workflow for evaluating environmental and health risks of dl-POPs at industrial hotspot regions. By developing validated and user-friendly analytical strategies, routine monitoring of dl-POPs can be conducted effectively, especially in developing countries. The study validates a gas chromatography triple quadrupole mass spectrometer based analytical workflow as a substitute for conventional magnetic sector high resolution mass spectrometer technique and demonstrates its utility for predicting enviro-food-health nexus by analyzing fish and sediment samples from a POPs hotspot in India. The study highlights the importance of periodic surveillance of dl-POPs to safeguard human health and the environment.

Summary: This study analyzed the concentrations of persistent organic pollutants (POPs) in Franciscana dolphins from three regions in Brazil. The results showed that PCBs and DDTs were the predominant pollutants, with the highest PCB concentrations observed in highly urbanized and industrial areas. The sex and maturity of the dolphins had significant effects on the POPs concentrations. Although the concentrations of POPs are declining, PCB levels remain high and pose adverse health effects on the dolphins.

Summary: The study found that exposure to PAHs and PCBs in marine sediments had short-term sublethal effects on sea urchins, which were explained at the molecular level. Twenty-five new genes were identified, and it was discovered that they were functionally connected to genes previously defined as molecular targets of these pollutants. The expression of these genes was affected by PAHs and PCBs.

Summary: Recent studies have shown that unintentionally produced PCBs are major contributors to atmospheric PCBs and are controlling PCB burdens in agricultural soils across China. The dominant contributors to PCBs in Chinese agricultural soils are the legacy of historically produced and used commercial PCB mixtures, especially high-chlorinated congeners. Unintentional sources, such as pigment/paint, combustion-related sources, and polymer sealants, account for a significant portion of total PCBs in Chinese soils.

Summary: This study used geospatial estimation to assess the exposure of ALS patients to airborne contaminants and found that airborne lead and polychlorinated biphenyls (PCBs) may be associated with an increased risk of ALS. The main sources of these contaminants include small aircraft, power plants burning biomass, and industrial boilers. The association with a residential history of lead exposure was confirmed in two additional cohorts.

Summary: In this study, a tandem mass spectrometry molecular networking-based strategy was demonstrated to be effective for product identification, reaction dynamics monitoring, and active compound targeting in combinatorial synthesis. Both expected and side products can be characterized using molecular networking based on their mass spectrometry fragmentation patterns. Time-dependent molecular networking was also integrated to track reaction dynamics for optimizing target product yields in high-throughput screening of active compounds.

Summary: Antibiotic residues in mariculture environments have been detected globally, but little information is available about their dynamic levels, source, behavior, and fate during the whole culture process. This study investigated the occurrence, bioaccumulation, source, fate, and human dietary risk of 19 antibiotics in mariculture ponds near the Maowei Sea in South China. Fourteen antibiotics were detected in the ponds, with fluoroquinolones being the most abundant, and significant variations in antibiotic concentration were observed throughout the culture process.

The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
