To investigate the effects of imidacloprid on natural stream communities under controlled conditions, experimental streams were dosed with imidacloprid at concentrations ranging from 0.061 to 220 micrograms per liter (µg/L) for a period of 10 days. Natural stream macroinvertebrate communities were obtained from the Cache La Poudre River (Larimer County, CO) by colonizing trays full of large gravel for 75 days. The trays were added to laboratory experimental streams (mesocosms) at the USGS Fort Collins Science Center in Fort Collins, CO. At the end of 10 days, invertebrate abundance metrics were analyzed in relation to measured imidacloprid concentrations in water from the experimental streams. Declines in total...
Although San Francisco Bay has a “Golden Gate”, it may be argued that it is the “Silver Estuary”. For at one time the Bay was reported to have the highest levels of silver in its sediments and biota, along with the only accurately measured values of silver in solution, of any estuarine system. Since then others have argued that silver contamination is higher elsewhere (e.g., New York Bight, Florida Bay, Galveston Bay) in a peculiar form of pollution machismo, while silver contamination has measurably declined in sediments, biota, and surface waters of the Bay over the past two to three decades. Documentation of those systemic temporal declines has been possible because of long-term, ongoing monitoring programs,...

These data present chemistry and toxicity results from freshwater stream sediments collected from 99 wadable stream sites across eleven states in the Midwestern U.S. as one component of a larger USGS study in the summer of 2013. This data presents a selected suite of chemistry collected at these sites (PAHs, Organochlorines, PCBs, Trace Elements, and current use pesticides) used in calculating a Probable Effect Concentration-Likely Effect Benchmark quotient mixture score for contaminants measured in sediments. The toxicity data presents results of toxicity tests following ASTM and US EPA standard methods for sediment toxicity tests with the amphipod Hyalella azteca (28-d exposure), the midge Chironomus dilutus (10-d),...
Description of Work At two of Wisconsin's Areas of Concern (AOCs) on Lake Michigan, the Sheboygan River AOC and Milwaukee Estuary AOC, the USGS will assess whether sediment toxicity from PCBs, PAHs, selected metals, ammonia, or dissolved oxygen is present at acutely toxic or chronically toxic concentrations using sediment toxicity tests conducted with amphipods and midges. Study planning and literature search have been completed. Sediment was collected in October 2016 from sites in the two AOCs and sites in two non-AOC comparison sites. Assesments will be done at two additional sites: Kewaunee River and Oak Creek. Laboratory toxicity tests and chemical analyses are in progress, including sediment toxicity testing...

Description of Work USEPA Region 5 previously funded a study in 2011 evaluating the toxicity of nitrogen compounds to a select number of pond-dwelling amphibians. The objective of this new study will be to determine the toxicity of nitrogen compounds to stream-dwelling amphibians. Nitrogen contamination in aquatic systems results from the decomposition of organic matter, as well as through agricultural inputs, sewage effluents and industrial activities. Nitrogen in its various forms is of ecological concern because of its ubiquitous distribution and toxicity to aquatic life. Nitrogen compounds pose a hazard to aquatic larval stages of amphibians, affecting survival and development, and inducing deformities and behavioral...

Description of Work The sensitivity of listed species of fish or amphibians was evaluated in acute and chronic toxicity tests conducted with a range of inorganic or organic chemicals with different toxic modes of action. Results of these studies indicate that the acute or chronic sensitivity of rainbow trout, but not fathead minnow, frequently provided protective acute or chronic toxicity thresholds for most of the listed species evaluated. However, only a limited number of species of sculpins or darters were included in this evaluation, and not all species tested occurred in the Great Lakes watershed. The objective of the proposed study will be to: (1) provide additional chronic toxicity data for sculpins or darters...

Description of Work Currently, a standard test method does not exist for evaluating the effects of sediment-associated toxicants on freshwater mussels. A standard guide for conducting water-only laboratory toxicity tests with freshwater mussels was approved in 2006 (ASTM 2008a) and provides a tested and validated, consensus-based methodology for conducting acute or chronic water toxicity tests with the early life stages (glochidia and juveniles) of freshwater mussels. Several recent peer-reviewed scientific publications have presented data on various toxicants (Bringolf et al. 2007a,b,c; Wang et al. 2007a,b,c) generated with this method and demonstrate consistency and reliability in inter-laboratory (round robin)...
A number of streams in Colorado were found to contain waterborne selenium concentrations that consistently exceeded the current U.S. EPA chronic criterion of 5 μg/L and often exceeded the acute criterion of 20 μg/L. Despite these elevated concentrations, no biological impact was observed. These findings led to a review of selenium exposure pathways in freshwater. The literature strongly indicates that chronic selenium toxicity can result from accumulation of selenium in the sediment, movement into the food chain, and resulting dietary uptake. Chronic toxicity does not appear to be strictly a result of waterborne selenium concentrations. In fact, dissolved selenium concentrations are a poor predictor...

Recent concern for the adverse effects from neonicotinoid insecticides has centered on risk for insect pollinators in general and bees specifically. However, natural resource managers are also concerned about the risk of neonicotinoids to conservation efforts for the monarch butterfly (Danaus plexippus) and need a tool to estimate risk for wild monarch butterflies exposed to clothianidin. In the present study, monarch butterfly larvae were exposed to contaminated milkweed plants from hatch until pupation, and the effects upon larval survival, larval growth, pupation success, and adult mass were measured. Soils dosed with a granular insecticide product lead to average clothianidin concentrations of 10.8 - 843 ng/g...

These data consists of three related tables describing in-situ field conditions including pesticide concentration, water quality, and post-treatment survival of crayfish associated with the application of a pesticide to a stormwater retention pond and burrows to suppress or eradicate an invasive crayfish species, Procambarus clarkii, in support of high-priority research developing control methods to mitigate impacts of invasive crayfish within the Great Lakes Basin. Effectiveness of the treatment was accessed using an in-situ bioassay and by measuring pesticide concentrations in water, sediment, and caged crayfish. Water quality data, including temperature, pH, specific conductance, dissolved oxygen, alkalinity,...
Data from this study will be used to extend the current pH/ alkalinity sea lamprey MLC prediction chart used to set 3-trifluoromethyl-4-nitrophenol (TFM) concentrations for treating streams to control sea lamprey populations in the Great Lakes. The current chart predicts levels of TFM required to kill 99.9% of larval sea lampreys in water with alkalinities up to 260 mg/L. Some streams in lower Michigan, however, exceed the current 260 mg/L alkalinity threshold. Treatment managers have requested an extension of the chart to an alkalinity of 300 mg/L for pHs between 8.0 and 8.5. Exposures were conducted with TFM in water at pH 8.0 and 8.5 at alkalinities 260 and 300. Differences in TFM toxicity between the two alkalinities...

In order to estimate the costs of chemical control of non-indigenous crayfish versus the cost of manual inspection of fish hatchery shipments a cost analysis was performed. The data includes ranking the likelihood of missing non-indigenous crayfish and effects on fish of handling during manual searches and the effects on fish during chemical exposure. The data also includes estimates of the time, staff, and salary requirements and cost of materials for each approach.

The exposure of white-footed mice (Peromyscus leucopus) to lead and cadmium and the potential associated toxic effects were examined at three sites contaminated with lead in the Southeast Missouri Lead Mining District and at a reference site. Mice from the contaminated sites showed evidence of oxidative stress and red-blood cell δ-aminolevulinic acid dehydratase (ALAD) activity was depressed by an average of 68% at the most contaminated site. However, histological examinations of the liver and kidney, cytologic examination of blood smears and biomarkers of lipid peroxidation and DNA damage failed to show evidence of toxic effects from lead. The biomagnification ratio of cadmium (hepatic concentration/ soil concentration)...
