Xerophilic Alopecosa sulzeri (Pavesi, 1873) (Araneae: Lycosidae)-a brand-new wolf spider kinds in Poland.
Moreover, MR analysis indicated the changes in serum molybdenum and zinc levels might be not caused by NAFLD, further confirmed our findings in cross-sectional and longitudinal analyses. V.Endocrine disrupting compounds (EDCs), pharmaceuticals and personal care products (PPCPs) have been of great concern as emerging contaminants of aquatic environment. Therefore, there is an urgent need to identify top contaminants so as to allocate better management measures. A list of 77 pharmaceuticals, 20 personal care products (PCPs) and 36 EDCs that were frequently detected in Chinese surface waters was examined in this study. The reported chemicals were concentrated in the highly populated and industrialized areas of China (e.g. the Bohai region, Yangtze River Delta and Pearl River Delta). The concentrations of EDCs and PPCPs were closely related to human domestic sewage and industrial wastewater discharge, and they were generally higher than or at least comparable to most of global rivers. Based on the proximity between the medians of reported exposure concentrations and effect concentrations, the risk ranking results showed that EDCs, e.g. estrone (E1), estriol (E3), 17α-ethynylestradiol (EE2), and PCPs, e.g. triclocarban (TCC), triclosan (TCS), were deemed to represent higher risks to aquatic organisms across China, as well as the Northern rivers (including the Bohai region), Yangtze River Basin, and Pearl River Basin. Pharmaceuticals posed relatively lower risks to organisms owing to their higher effect concentrations. By comparison, the Northern rivers were hotspots where many chemicals were identified as posing greater risks than the Yangtze River Basin and Pearl River Basin. Fish was the most sensitive taxa to 17β-estradiol (βE2) and EE2, which was almost 100,000 times higher risk than algae and worms. Atrazine (ATZ) and galaxolide (HHCB), posed comparably higher risks to algae and worms. The results of this work provide a sound guidance for future monitoring and management of chemicals in China. In the recent decades, Cd burden in cocoa-based products threatened global food safety, human health and the future of chocolateries. Increased Cd bioavailability is an acute problem in cacao-based horticulture. Poverty, poor maintenance, unjustified traditional farming, and paucity of knowledge on Cd-binding propensity in cacao discourage the application of risk-mitigation measures. Progressive accumulation of Cd, with a half-life of 10-30 years, in the human body even at ultra-trace levels may lead to serious health complications. If Cd accumulates in the food chain through cocoa products, consequences in children, who are the primary consumers of chocolates, include morbidity and mortality that may result in a significant demographic transition by the year 2050. Developing cacao clones with an innate capability of taking up low Cd levels from soils, and site-specific Cd-cacao research might contribute to limiting the trophic transfer of Cd. This review highlights the possible routes for Cd uptake in cacao plants and discusses the measures to rescue the chocolateries from Cd pollution to promote "healthy" cacao farming. The potential human health risks of chocolate-laden Cd and mitigation strategies to minimize Cd burden in the human body are also presented. The challenges and prospects in Cd-cacao research are discussed as well. Benzene is a carcinogen. Exposure to benzene severely threatens people's health. While its indoor sources such as paint and solvent have been tightly regulated as a result of its inclusion into indoor air standards globally, its outdoor emission from traffic and industry is less addressed. Since human's exposure to benzene mainly occurs indoors, how outdoor benzene affects indoor concentrations is a critical issue, but not well discussed yet. This study summarized 118 pairs of outdoor-indoor measurement of benzene concentrations mainly published in the past five years. We found that the outdoor benzene concentrations measured in developing countries exceed 5 μg/m3, an annual concentration limit recommended by Europe Union, more often than developed ones. It implies a worse benzene pollution situation in the developing places, probably due to strong emission from traffic and industry. The outdoor/indoor concentration ratio is 0.69 and 0.84 for the developing and developed places, respectively. It indicates a significant, if not dominant, role of outdoor benzene in formulating indoor concentrations over indoor sources. Controlling outdoor benzene emission is therefore highlighted. Actions should be taken to regulate benzene emission sources such as traffic and industry. This is particularly urgent to protect occupants in buildings close to roads and factories. V.Microplastics (MPs) have been recognized as transport vectors for micropollutants in the natural water environment and the food web; therefore, the sorption behavior of contaminant on MPs has recently gained an increased attention. However, a consensus has not yet been reached and information about the adsorption of water contaminants on real MPs remains elusive. AZD9291 solubility dmso Herein, we raise the question of "Should we continue using pure polymers as surrogates for real MPs?" This first systematic study compared the adsorption of multiple micropollutants (i.e. a pesticide, a pharmaceutical, and perfluoroalkyl substances (PFAS)) on a large set of MPs (i.e. 20 well-characterized MPs) and kaolin. Material characterizations results showed various physicochemical and compositional differences between real and pure MPs. Pure polymers had lower normalized uptake values than real MPs in most cases. This was attributed to the surface roughness and/or the presence of fillers (e.g. talc and glass fiber) in real samples. Further, preloaded MPs with natural organic matter (NOM) showed an increased uptake of micropollutants due to forming a complex with NOM and/or co-sorption. These findings indicate that employing real MPs in research studies is critical for obtaining environmentally meaningful results, and the evaluation of MPs sorption behavior without NOM preloading can result in a significant underestimation for their actual values. We also provided an outlook the key areas for further investigations.
