AbstractAcetylene (C2H2) is a molecule rarely found in nature, with very few known natural sources, but acetylenotrophic microorganisms can use acetylene as their primary carbon and energy source. As of 2018 there were 15 known strains of aerobic and anaerobic acetylenotrophs; however, we hypothesize there may yet be unrecognized diversity of acetylenotrophs in nature. This study expands the known
Ecological consequences of neonicotinoid mixtures in streams
Neonicotinoid mixtures are common in streams worldwide, but corresponding ecological responses are poorly understood. We combined experimental and observational studies to narrow this knowledge gap. The mesocosm experiment determined that concentrations of the neonicotinoids imidacloprid and clothianidin (range of exposures, 0 to 11.9 μg/liter) above the hazard concentration for 5% of species (0.0
Pesticide exposure of wild bees and honey bees foraging from field border flowers in intensively managed agriculture areas
Bees are critical for food crop pollination, yet their populations are declining as agricultural practices intensify. Pollinator-attractive field border plantings (e.g. hedgerows and forb strips) can increase bee diversity and abundance in agricultural areas, however recent studies suggest these plants may contain pesticides. Pesticide exposure for wild bees in agricultural areas remains largely u

Organic Contaminants in Reuse Waters and Transport Following Land Application
Potential reuse waters contained unique mixtures of organic contaminants with the greatest number detected in treated municipal wastewater treatment plant effluent, followed by urban stormwater, and agricultural runoff. This study provided information for decisions on reuse strategies to support freshwater supplies.
Per-and Polyfluoroalkyl Substances (PFAS) Integrated Science Team
Increasing scientific and public awareness of the widespread distribution of per- and poly-fluoroalkyl substances (PFAS) in U.S. drinking-water supplies, aquatic and terrestrial ecosystems, wildlife, and humans has raised many public health and resource management questions that U.S. Geological Survey's (USGS) science can inform. The USGS Environmental Health Program's PFAS Integrated Science Team...
Pesticides Detected in Bees, Flowers, Soil, and Air within Pollinator-Attractive Row-Crop Border Plantings
Field study in California describes the potential for pollinator-attractive field borders in agricultural areas to become a pesticide exposure pathway to bees through soil, air, and plants.
