Extracts from Dated Lake Sediment Cores in the Athabasca Oil Sands Region Alter EROD Activity and Gene Expression in Avian Hepatocytes.

Environ Toxicol Chem 2021 Mar 10. Epub 2021 Mar 10.

Ecotoxicology and Wildlife Health Division, Environment and Climate Change Canada, National Wildlife Research Centre, Carleton University, Ottawa, ON, Canada, K1A 0H3.

Increases in oil sands mining operations in the Athabasca oil sands region have resulted in increased concentrations of polycyclic aromatic compounds (PAC) and heavy metals in aquatic systems located near surface mining operations. In this present study, sediment cores were collected from three lakes with varying proximity to surface mining operations to determine the differences in PAC concentrations. Sediment cores were separated into two sections - current mining (top [T]; 2000-2017) and pre-mining (bottom [B]; pre-1945) - and extracts were prepared for in vitro screening using a well-established chicken embryonic hepatocyte (CEH) assay.

Highly Contaminated Marine Sediments Can Host Rare Bacterial Taxa Potentially Useful for Bioremediation.

Front Microbiol 2021 1;12:584850. Epub 2021 Mar 1.

Department of Life and Environmental Sciences, Polytechnic University of Marche, Ancona, Italy.

Coastal areas impacted by high anthropogenic pressures typically display sediment contamination by polycyclic aromatic hydrocarbons (PAHs) and heavy metals (HMs). Microbial-based bioremediation represents a promising strategy for sediment reclamation, yet it frequently fails due to poor knowledge of the diversity and dynamics of the autochthonous microbial assemblages and to the inhibition of the target microbes in the contaminated matrix. In the present study, we used an integrated approach including a detailed environmental characterization, high-throughput sequencing and culturing to identify autochthonous bacteria with bioremediation potential in the sediments of Bagnoli-Coroglio (Gulf of Naples, Mediterranean Sea), a coastal area highly contaminated by PAHs, aliphatic hydrocarbons and HMs. Read More

Synergistic, antagonistic, and additive effects of heavy metals (copper and cadmium) and polycyclic aromatic hydrocarbons (PAHs) under binary and tertiary combinations in key habitat-forming kelp species of Chile.

Environ Sci Pollut Res Int 2021 Apr 11;28(14):18300-18307. Epub 2021 Mar 11.

Departamento de Ecología y Biodiversidad, Facultad de Ciencias de la Vida, Universidad Andres Bello, Santiago, Chile.

Heavy metals (HMs) and polycyclic aromatic hydrocarbons (PAHs) are persistent toxicants in coastal environments. Notably, in comparison to individual metal toxicity, knowledge about the effects of HMs and PAHs mixtures on kelps remains scarce. Accordingly, we performed in vitro experiments to determine the individual and combined effects of Cu, Cd, and PAHs on spore release, settlement, and germination on Macrocystis pyrifera and Lessonia spicata, two key-habitat forming kelp species of the coast of the Valparaíso Region in Chile.

Traffic-related microplastic particles, metals, and organic pollutants in an urban area under reconstruction.

Sci Total Environ 2021 Feb 7;774:145503. Epub 2021 Feb 7.

VTI, Swedish National Road and Transport Research Institute, SE-581 95 Linköping, Sweden; Geology and Geotechnics, Department of Architecture and Civil Engineering, Chalmers University of Technology, SE-412 96 Gothenburg, Sweden.

In urban environments, particularly areas under reconstruction, metals, organic pollutants (OP), and microplastics (MP), are released in large amounts due to heavy traffic. Road runoff, a major transport route for urban pollutants, contributes significantly to a deteriorated water quality in receiving waters. This study was conducted in Gothenburg, Sweden, and is unique because it simultaneously investigates the occurrence of OP, metals, and MP on roads and in stormwater from an urban area under reconstruction.

Dermatol Ther 2021 Mar 12;34(2):e14840. Epub 2021 Feb 12.

Skin Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

As the largest organ in the body, human skin is constantly exposed to harmful compounds existing in the surrounding environment as the first-line barrier. Studies have indicated that exposure to high concentrations of many environmental factors, such as ultraviolet (UV) radiation, outdoor air pollutants, including polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs), particulate matter (PM), heavy metals, gaseous pollutants, such as carbon monoxide (CO), nitric oxides (NO ), sulfur oxide (SO ), ozone (O ), and indoor air pollutants (solid fuels consumption), might interrupt the skin's normal barrier function. Besides, the intensity of the pollutants and the length of exposure might be a contributing factor. Read More

Department of Urology, University of Virginia, Charlottesville, VA, USA.

Idiopathic infertility is the most common individual diagnosis in male infertility, representing nearly 44% of cases. Research studies dating over the last half-century consistently demonstrate a decline in male fertility that is incompletely explained by obesity, known genetic causes, or diet and lifestyle changes alone. Human exposures have changed dramatically over the same time course as this fertility decline. Read More
