Showing papers in "Environmental Pollution in 2015"

TL;DR: The study provided the evidence that microplastics adsorb PAHs, emphasizing an elevated bioavailability of these chemicals after the ingestion, and the toxicological implications due to responsiveness of several molecular and cellular pathways to microplastic.

TL;DR: The present study shows that the release of OPs from a wide variety of commercial products and wastewater discharge might be considered as primary emission sources and that high potential of long-range atmospheric transport and persistence of OP would be responsible for their presence in various matrices on a global scale.

TL;DR: In this paper, the authors studied the uptake of microplastics under field conditions at six locations along the French-Belgian-Dutch coastline and collected two species of marine invertebrates representing different feeding strategies: the blue mussel Mytilus edulis (filter feeder) and the lugworm Arenicola marina (deposit feeder).

TL;DR: It is suggested that microplastic pollution was widespread and exhibited a relatively high level in commercial bivalves from China and more intensive investigations on microplastics should be conducted in seafood.

TL;DR: In this paper, the concentrations of suspended microplastics determine their bioavailability to low trophic organisms, and then possibly promoting the transfer of microplastic to higher trophics levels.

TL;DR: This is the first study to directly identify microplastic <5 mm in a cetacean species and it was not possible to ascertain whether prey were the source of microplastics.

TL;DR: Under simultaneous exposure to MP and Artemia, L-most fish showed a significant reduction of the predatory performance and efficiency, while M-est fish did not, suggesting that developmental conditions may influence the preyselection capability of fish.

TL;DR: Comparing with previously reported data, microplastics in the TGR were approximately one to three orders of magnitudes greater, suggesting reservoirs as potential hot spot for microplastic pollution.

TL;DR: In this article, the occurrence and spatial distribution of 11 OPE congeners and one synthetic intermediate triphenylphosphine oxide (TPPO) in 40 major rivers entering into the Bohai Sea were investigated.

TL;DR: Based on sediment depths and accumulation rates, microplastics have accumulated in the offshore region for less than 38 years and their burial increases the chance of microplastic preservation.

TL;DR: This study tests the performance of a low-cost sensor in high concentration urban environments in Xi'an, China and finds that the PUWP monitors were able to identify the High-technology Zone site as a potential PM2.5 hotspot with sustained high concentrations compared to the city average throughout the day.

TL;DR: It is found that throughout China current and future O3 levels induce wheat yield loss by 6.4-14.4% and 14.8-23.0% respectively, based on exposure concentration and stomatal O3 flux-response relationships obtained from the O3-FACE experimental results in China.

TL;DR: Long-term data reveal high plastic abundance in the southern North Sea, gradually decreasing to the north at increasing distance from population centres, with lowest levels in high-arctic waters.

TL;DR: Metal deposition trend to increase Cr, Ni and Cd levels in urban atmospheres due to changes in human activities over 70 years of urban growth.

TL;DR: Exposure to the Ag-incubated MPBs significantly reduced Ag uptake at both time points and also significantly increased the proportion of intestinal Ag.

TL;DR: The results showed that the residents in the e-waste recycling sites are facing a potential higher daily intake of heavy metals and a precautionary approach toward exposure, especially in neonates and children, seems warranted.

TL;DR: Metal-based nanoparticles may be translocated and biochemically modified in vivo, which may influence the fate of MNPs in the environment and bulk-XANES data showed that CuO NPs were transported from the roots to the leaves, and that Cu (II) combined with cysteine, citrate, and phosphate ligands and was even reduced to Cu (I).

TL;DR: The detection of a potentially cytotoxic metal as well as oxidant reactivity in disposable components of ENDS/e-cigarettes (batteries and cartomizers) using a fluorescein indicator raises concern regarding the safety of e-cigarettes use and the disposal of E-cigarette waste products into the environment.

TL;DR: Surprisingly, the ratios of water-insoluble organic carbon to elemental carbon showed significant increase at high RH levels, presumably indicating the formation of secondary organic aerosol that is not soluble in water.

TL;DR: Proper pretreatment, inflow dilutions through re-circulated effluent, pH adjustment, plant selection and intensifications in the wetland bed, such as aeration and bioaugmentation, are recommended according to the specific characteristics of industrial effluents.

TL;DR: This report reports on a spillage of industrial microplastic (IMP) from a production plant situated at an Austrian Danube tributary, which is the first identified point source of IMP litter in freshwater systems.

TL;DR: The study emphasized the significance of effective environmental management, particularly to ensure food security near battery facilities, and the non-cancer risks to children were 3-10 times higher than the acceptable level of 1, while the cancer risks were 5-200 times higher.

TL;DR: Brief campaigns to quantify the effect of trees on the dispersion of airborne particulates using high time resolution measurements along short transects away from roads are described, indicating recirculation, longer residence times and decreased dispersion downwind of trees.

TL;DR: Temporal variability in concentrations caused by weather variation was simulated using monthly weather data for a representative 31-year period to model temporally varying nano-particle concentrations in rivers, lakes and wetlands.

TL;DR: Overall, the evidence suggests that triclosan is an EDC, and the current evidence regarding its reproductive endocrine-disrupting effects, and potential mechanisms to provide insights for further study are described.

TL;DR: Human health risk assessment based on potential fish consumption indicates that these antibiotics do not appear to pose an appreciable risk to human health, and the first report of bioaccumulation patterns of antibiotics in wild fish bile and plasma is reported.

TL;DR: This paper overviews typical currently available devices and their characteristics, and original results of measurement and modelling in the aim of one low-cost PM monitor validation are presented.

TL;DR: The lowest concentrations of metals and nitrogen in mosses were generally found in northern Europe, whereas the highest concentrations were observed in (south-)eastern Europe for metals and the central belt for nitrogen.

TL;DR: Results suggest that groundwater, in addition to precipitation and surface runoff, is an important source of pesticides entering surface water, and legacy pesticides, metabolites and impurities are important for explaining the estimated total toxicity attributable to pesticides.

TL;DR: Three vegetation indices were found to be the most appropriate indices to detect the effects of petroleum pollution in the Amazon forest and show reduced levels of chlorophyll content, higher levels of foliar water content and leaf structural changes.
