Summary: The anthropogenic impact on the aquatic environment of the Rasa River in Croatia was investigated. The study used yellow European eel as a biological indicator to analyze PBDEs, PCBs, DDT isomers, and major and trace elements. The results showed generally low contamination levels in the surrounding area, with organic contaminants increasing in muscle with lipid content, length, weight, and body condition. Metal(loid) levels decreased or remained unchanged with increasing size, except for a few elements that accumulated in the liver at the downstream location.

Summary: Previous studies have focused on the direct impact of temperature on the foliar uptake of persistent organic pollutants (POPs), but few studies have explored the indirect impacts of low temperature on foliar uptake. Our study at the treeline on the Tibetan Plateau found that colder climate conditions led to enhanced surface adsorption and slower penetration of dichlorodiphenyltrichloroethanes (DDTs) in leaves, resulting in higher uptake efficiencies and reservoir capacity. The relative humidity, correlated with temperature, also influenced the uptake rates of DDTs.

Summary: Comprehensive monitoring of air and soil in Oman was conducted to understand the sources and fate of organochlorine pesticides. The study found DDTs in agricultural soil samples with a wide range of concentrations and highest levels at locations with intensive agricultural practices. Among the newly enlisted POPs, pentachlorobenzene was detected most frequently in both air and soil samples. The study indicates volatilization processes from soil and the potential cleansing effect of oceanic air on atmospheric OCP levels.

Summary: This study investigated the association between persistent organic pollutants (POPs) and type 1 diabetes (T1D) in youth. The results suggest that certain POPs may be associated with an increased risk of T1D and can negatively impact the function and viability of pancreatic beta-cells.

Summary: A temperature-assisted solidification of floating organic droplet-dispersive liquid-liquid microextraction method was developed for the extraction and preconcentration of organochlorine pesticides from cocoa powder samples before determination by GC-ECD. The method provided high extraction recoveries, low detection limits, wide linear ranges, and acceptable repeatability, making it suitable for concentration measurements across a range of levels.

Summary: This case-control study in Algeria found that environmental exposure to certain persistent organic pollutants is associated with an increased risk of type 2 diabetes in the general population. Diabetic subjects had higher plasma concentrations of these pollutants, emphasizing the potential impact of endocrine disruptors on diabetes development.

Summary: The study found that there is a relationship between the oxidative microenvironment of adipose tissue and the concentration of persistent organic pollutants with cancer development. Certain enzymes were found to be associated with the risk of non-hormone-dependent cancer, and certain POPs were also positively associated with the risk of NHD cancer.

Summary: The objective of this study was to estimate the plasma levels of organochlorine pesticides and PCBs in hospitalized individuals in Petropolis, Brazil. Compared to data present in the literature, the concentration of POPs was lower, and individuals from 55 to 64 years of age and women presented a higher average concentration of organochlorine pesticides; men also presented a high concentration of PCBs.

Summary: This study investigated the presence of Dechlorane series flame retardants (DECs) in surficial sediments from the Pearl River Delta, China. The results showed that DP and Mirex were the main components, with DP concentrations positively correlated with urban activities. Additionally, anti-Cl-11-DP was found ubiquitously in the sediments, indicating it was co-emitted with anti -DP rather than a dechlorination byproduct.

Summary: The study evaluated the presence of persistent organic pollutants (POPs) in the liver tissue samples of juvenile green sea turtles collected on the southeastern Brazilian coast. The main POPs found were (sic)-HCH and PCBs. Despite the low concentrations found, it was indicated that the sea turtles were exposed to these compounds.

Summary: The Rio de Ondas Hydrographic Basin in Bahia state, Brazil, is heavily affected by agricultural activities, posing a potential risk to aquatic environments due to the use of organochlorine pesticides. The study showed that despite the ban on these pesticides since 1985, their residues were widely distributed in the basin, especially during the rainy season.

Summary: This study investigated the association between OCPs concentrations in PPAT and prostate cancer aggressiveness, and found significant ethno-geographic variation in exposure. Most OCPs were positively correlated with age and BMI, while mirex showed an inverse association with aggressive features of PCa.

Summary: This study longitudinally explores the public healthcare costs associated with long-term exposure to a mixture of 8 persistent organic pollutants (POPs) in residents of two areas in Granada Province, Southern Spain. The results suggest that long-term exposure to these pollutants may increase healthcare costs and impact the efficiency of healthcare systems. However, further research is needed to determine whether interventions to reduce human exposure should be considered in healthcare policies, due to the limitations of the study.

Summary: Persistent organic pollutants (POPs) accumulated in the body may be associated with the incidence of certain diseases. This study investigated the association between the concentration of POPs and circulating metabolites in human blood samples. The findings suggest that metabolites related to short-chain fatty acids and creatine can be useful risk indicators for estimating the effect of PCB exposure.

Summary: This study reports the use of electropolymerised molecularly imprinted polymers (E-MIPs) for the determination of dioctyl phthalate (DOP). E-MIPs with high affinity for DOP were produced using commercially available screen printed electrodes (SPEs). The E-MIPs showed rapid and accurate detection of DOP in freshwater samples.
