Mapping Dynamic Exposure: Constructing GIS Models of Spatiotemporal Heterogeneity in Artificial Stream Systems.
Abstract In flowing environments, the degree of turbulent flow determines the movement and distribution of chemicals. Variation in flow alters the patchiness of toxicant plumes within a stream ecosystem. This patchiness translates into variability in exposure pulses for organisms encountering the toxic plume. Throughout a stream, the processes that give rise to chemical plume structure will vary as a function of local flow characteristics. This research examines the influence of toxicant mode of entry and stream flow velocity on the spatiotemporal patterning of exposure. Two introduction treatments were evaluated:...

Deltamethrin Impairs Honeybees (Apis mellifera) Dancing Communication.
Abstract As a commonly used pyrethroid insecticide, deltamethrin is very toxic to honeybees, which seriously threatens the managed and feral honeybee population. Because deltamethrin is a nerve agent, it may interfere with the nervous system of honeybees, such as dance behavior and memory-related characteristics. We found that the waggle dances were less precise in honeybees that consumed syrup containing deltamethrin (pesticide group) than those that consumed normal sucrose syrup (control group). Compared with the control group, honeybees of the pesticide group significantly increased number of circuits per 15&nb...

Bt Proteins Exacerbate Negative Growth Effects in Juvenile Rusty (F. rusticus) Crayfish Fed Corn Diet.
Abstract The adoption of genetically modified (GM) crops has occurred rapidly in the United States. The transfer of GM corn byproducts from agricultural fields to nearby streams after harvest is significant and occurs well into the post-harvest year. These corn leaves, stems, and cobs then become a detrital food source for organisms, such as shredders in the stream ecosystem. Considering that the nontarget effects of Bt corn have been observed in some terrestrial organisms, we assessed whether Bt toxins affect an important aquatic organism, juvenile F. rusticus crayfish. Juvenile crayfish were fed six distinct die...

Lead and Other Trace Elements in Danish Birds of Prey.
JS, Sonne C Abstract Lead is a widely used and toxic heavy metal that poses a serious hazard to wildlife species and their ecosystems. Lead is used for production of hunting ammunition. Via gunshot or rifle projectiles, it spreads in ecosystems and may end up in predators and scavengers feeding on wounded or dead animals shot with lead-based ammunition. To assess to what degree Danish raptors are subject to lead contamination, we measured the content of lead in liver tissue from Danish birds of prey (n = 137). Additionally, the study included values for 54 other trace elements. In our analysis, empha...

Glyphosate- and Fipronil-Based Agrochemicals and Their Mixtures Change Zebrafish Behavior.
Abstract Environmental contamination caused by the human occupancy and economic activities that generate a wide range of contaminated effluents that reach natural water resources, is a current reality. Residues of agrichemicals used in plant production were detected in different environments and in different countries. Among these agrochemicals, we studied a glyphosate-based herbicide (GBH), a fipronil-based insecticide (FBI), and their mixtures (GBH + FBI). Zebrafish exposed to 3 and 5 mg/L of GBH spend more time in the top zone and less time in the bottom zone. Fish exposed to 0.009 and 0.018&...

Environmental Transformation of Pharmaceutical Formulations: A Scientific Review.
H, Mikov M Abstract Environmental pollution caused by pharmaceuticals and their transformation products (TPs) has become an increasingly important concern, due to the increased use of pharmaceutical formulations exposed to environmental change. Considerable concerns have been raised regarding potential toxic effects of the transformation products of pharmaceutical formulations on human health. Environmental risk assessments are mostly based on one active component, which causes different ecotoxicological effects, albeit the particular component is present in the environment as a part of a multicomponent mixt...

Spatial and Temporal Variation of Atmospheric Particulate Matter in Bangalore: A Technology-Intensive Region in India.
Abstract All of India's megacities are experiencing acute air pollution problems due to the accelerated urbanization/industrialization and rapid economic growth. Nowadays, environmental pollution due to particulate matter is a major threat to human health and our regional air quality. Long-term air pollution data with the high spatial and temporal resolution are required to understand regional air quality and its effects on environmental degradation and human health. In view of the above, the particulate matter (PM2.5: particles with diameters less than 2.5 μm and PM10: particles with diameters less than 1...

Source Apportionment of Polychlorinated Biphenyls in Atmospheric Deposition in the Seattle, WA, USA Area Measured with Method 1668.
Abstract Atmospheric deposition can be an important pathway for the delivery of toxic polychlorinated biphenyls (PCBs) to ecosystems, especially in remote areas. Determining the sources of atmospheric PCBs can be difficult, because PCBs may travel long distances to reach the monitoring location, allowing for a variety of weathering processes that may alter PCB fingerprints. Previous efforts to determine the sources of atmospheric PCBs have been hampered by the electron capture detection methods used to measure PCBs. In this work, EPA method 1668, which is capable of measuring all 209 congeners, was used to measure...

Assessments of Metals in Coastal Environments: State of Art.
This study is an overview of the assessments of metal contamination in coastal environments for the past five decades. Research articles with evaluations in sediments and biota were quantified and had their content visited for the registry of (1) the source of metals (anthropogenic or natural), (2) assessed country/territory, (3) groups of organisms assessed, (4) trophic transfer evaluation, (5) spatio-temporal variations, and (6) metals evaluated. We found an increase in the number of assessments over the years, mainly from 2014. The majority of the assessments pointed to anthropogenic sources of metals. The United States...
