Accumulation of the Toxic Metal Mercury in Multiple Tissues of Marine-Associated Birds from South Florida.

Arch Environ Contam Toxicol 2022 May 22;82(4):493-505. Epub 2022 Apr 22.

Halmos College of Arts and Sciences, Nova Southeastern University, 8000 North Ocean Drive, Dania Beach, FL, 33004, USA.

One of the best studied global "hot spots" for ecological mercury (Hg) contamination is south Florida (USA), where elevated Hg concentrations in environmental media and regional wildlife were first described over thirty years ago. While Hg contamination has lessened in this region, it is still critical to monitor Hg uptake and potential risks in south Florida wildlife, especially in marine-associated birds, which are known to accumulate potentially toxic Hg levels. In this study, total Hg (THg) concentrations were measured in liver, kidney, muscle, and feathers of 101 individuals from seven species of south Florida birds: brown pelican Pelecanus occidentalis, double-crested cormorant Phalacrocorax auratus, herring gull Larus argentatus, laughing gull Leucophaeus atricilla, northern gannet Morus bassanus, royal tern Thalasseus maximus, and osprey Pandion halietus.

Treating Agricultural Runoff with a Mobile Carbon Filtration Unit.

Arch Environ Contam Toxicol 2022 May 16;82(4):455-466. Epub 2022 Apr 16.

Department of Environmental Toxicology, Marine Pollution Studies Laboratory, University of California Davis, 34500 Highway One, Monterey, CA, 93940, USA.

Several classes of pesticides have been shown to impair water quality in California, including organophosphates, pyrethroids and neonicotinoids. Vegetative treatment systems (VTS) can reduce pesticide loads and associated toxicity in agricultural runoff, but many water-soluble pesticides such as neonicotinoids are not effectively treated by VTS, and VTS installation is not always an option for growers required to remove non-crop vegetation for food safety concerns. Recent studies have shown that biochar filtration can be used to remove soluble contaminants, especially when coupled with other VTS components. Read More

Metals in Plant Functional Types of Ombrotrophic Peatlands in the Sudetes (SW Poland).

Arch Environ Contam Toxicol 2022 May 9;82(4):506-519. Epub 2022 Apr 9.

Institute for Water and Wetland Research, Department of Environmental Science, Radboud University, Huygens Building, Heijendaalseweg 135, 6525 AJ, Nijmegen, The Netherlands.

The Sudetes are remarkable for the variety and number of peat bogs which receive nutrients via precipitation from atmospheric deposition as the only source of minerals. As this type of peat bogs with a very low buffering capacity is affected in the Sudetes by long-range exhausts from the former Black Triangle, strong response to atmospheric contamination may be expected. Therefore these peat bogs are highly suitable for bioindication purposes. Read More

Chloride Toxicity to Native Freshwater Species in Natural and Reconstituted Prairie Pothole Waters.

Arch Environ Contam Toxicol 2022 Apr 29;82(3):416-428. Epub 2022 Mar 29.

Columbia Environmental Research Center - Jackson Field Research Station, U.S. Geological Survey, Jackson, WY, USA.

Oil and gas extraction in the Prairie Pothole Region (PPR) of the northern USA has resulted in elevated chloride concentrations in ground and surface water due to widespread contamination with highly saline produced water, or brine. The toxicity of chloride is poorly understood in the high hardness waters characteristic of the region. We evaluated the toxicity of chloride to two endemic species, Daphnia magna (water flea) and Lemna gibba (duckweed), exposed in field-collected waters (hardness ~ 3000 mg/L as CaCO) and reconstituted waters (hardness 370 mg/L as CaCO) intended to mimic PPR background waters.

Chemical and Carbon Isotopic Characterization of a Karst-Dominated Urbanized Watershed: Case of the Upper San Antonio River.

Arch Environ Contam Toxicol 2022 Apr 26;82(3):439-454. Epub 2022 Mar 26.

San Antonio River Authority, San Antonio, TX, 78283, USA.

Urbanization and agriculture are two key factors that place demands on water resources and serve as sources of anthropogenic pollution into inland waterways. The San Antonio River, which is sourced from a karst aquifer, plays an important recreational and scenic role, yet effective management is often hampered by the lack of understanding of the chemical characterization of the water system. The karst-dominated Edwards Aquifer watershed in south-central Texas is an ideal watershed to understand water-rock interaction (carbonate dissolution) and anthropogenic impact on our water resources.

Perfluoroalkyl Substances (PFASs) in the Canadian Freshwater Environment.

Arch Environ Contam Toxicol 2022 May 26;82(4):581-591. Epub 2022 Mar 26.

Water Quality Monitoring and Surveillance Division, Water Science and Technology, Environment and Climate Change Canada, 45 Alderney Drive, Dartmouth, NS, B2Y 2N6, Canada.

Per- and polyfluoroalkyl substances (PFASs) are anthropogenic substances that are very stable in the receiving environment. Legacy perfluoroalkane sulfonates (PFSAs) and perfluoroalkyl carboxylic acids (PFCAs) are especially persistent and resistant to typical environmental degradation processes and therefore are distributed across all trophic levels and environmental compartments (soil, air, water). Since most uses of perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), and LC-long-chain PFCAs are banned in Canada, alternative PFASs have been in use for a number of years. Read More

Arch Environ Contam Toxicol 2022 Apr 24;82(3):429-438. Epub 2022 Mar 24.

Universidad de Alcalá, Facultad de Ciencias, Departamento de Ciencias de la Vida, Unidad Docente de Ecología, Biological Invasions Research Group, Universidad de Alcalá, Plaza de San Diego S/N, 28801, Alcalá de Henares, Madrid, Spain.

Behavioral endpoints are important parameters to assess the effects of toxicants on aquatic animals. These endpoints are useful in ecotoxicology because several toxicants modify the animal behavior, which may cause adverse effects at higher levels of ecological organization. However, for the development of new bioassays and for including the behavior in ecotoxicological risk assessment, the comparison of sensitivity between different behavioral endpoints is necessary.

Arch Environ Contam Toxicol 2022 May 23;82(4):467-480. Epub 2022 Mar 23.

Graduate School of Biosphere Science, Hiroshima University, 1-7-1 Kagamiyama, , Higashi-Hiroshima, Hiroshima, 739-8521, Japan.

Polycyclic aromatic hydrocarbons (PAHs) were analyzed to elucidate the distribution, ecological risk, pathways, and fluxes of these pollutants in and around the Seto Inland Sea, an industrialized coastal region of Japan. High molecular weight PAHs (5-6 rings) were primarily found in regions close to the bay estuaries, and their proportions decreased at distances further from the estuaries (offshore areas), where low molecular weight PAHs (2-4 rings) were more ubiquitous. Screening-level risk assessments revealed that the PAHs found in the sediments should have no adverse effects on benthic communities. Read More

Heavy Metal Concentration in Neotropical Aquatic Snakes (Helicops pastazae) and Its Potential as a Bioindicator of Water Pollution.

Arch Environ Contam Toxicol 2022 Apr 31;82(3):367-378. Epub 2022 Jan 31.

Department of Biological Sciences, Universidad de los Andes, Bogotá, D.C., Colombia.

The purpose of this study was to test the potential role of the aquatic snake Helicops pastazae as an indicator of water pollution caused by heavy metals. In particular, we tested whether the total heavy metal concentration is related to (1) the position (upstream vs downstream) of the sampling point and its distance from the point where wastewater is discharged; (2) the taxonomic group studied: piscivorous snakes vs characid fish that occupy the same habitats; and (3) the organ or tissue examined: snake liver versus muscle. We used atomic absorption spectrophotometry with electrothermal atomization to quantify cadmium (Cd), chromium (Cr) and lead (Pb) and found significant differences between some of the sampling points, with particularly high metal concentrations detected upstream at point 1.

Toxicity of Tire Rubber Microplastics to Freshwater Sediment Organisms.

Arch Environ Contam Toxicol 2022 Feb 20;82(2):180-190. Epub 2021 Dec 20.

Department of Environmental and Biological Sciences, University of Eastern Finland, Kuopio campus, PO Box 1627, 70211, Kuopio, Finland.

High emission of tire rubber particles to the surrounding environment is an inevitable consequence of the current habits of transportation. Although most of the emissions stay within a close range of the sources, it has been proven that the smallest particles can be transported to remote locations through the atmosphere, including inland water bodies. It has been estimated that a relevant portion of the global emissions of tire rubber particles reach surface waters, but effects on aquatic life in the receiving water bodies are not completely understood.
