Improved analytical methods can quantify hundreds of pesticide transformation products (TPs), but understanding TP occurrence and potential toxicity in aquatic ecosystems remains limited. We quantified 108 parent pesticides 116 TPs more than 3 700 samples from 442 small streams mostly urban basins across five major regions the United States. were detected nearly as frequently parents (90 95% streams, respectively); 102 at least once 28 >20% one region—TPs 9 herbicides, 2 fungicides (chlorothalonil thiophanate-methyl), 1 insecticide (fipronil) most detected. occurred commonly during baseflow conditions, indicating chronic environmental exposures to organisms likely importance groundwater a source. Hazard quotients based on acute aquatic-life benchmarks for invertebrates nonvascular plants vertebrate-centric molecular endpoints (sublethal effects) range contribution risk highlight several exposure–response data gaps. A precautionary approach using equimolar substitution or missing indicates that effects could be underestimated by an order magnitude more.

Neonicotinoid mixtures are common in streams worldwide, but corresponding ecological responses poorly understood. We combined experimental and observational studies to narrow this knowledge gap. The mesocosm experiment determined that concentrations of the neonicotinoids imidacloprid clothianidin (range exposures, 0 11.9 μg/liter) above hazard concentration for 5% species (0.017 0.010 μg/liter, respectively) caused a loss taxa abundance richness, disrupted adult emergence, altered trophodynamics, while two dose-dependent synergistic effects. In 85 Coastal California streams, were commonly detected [59% samples (n = 340), 72% streams], frequently occurred as (56% streams), potential toxicity was dominated by (maximum 1.92 2.51 μg/liter). Ecological field consistent with effects observed experiment, indicating neonicotinoid pose greater than expected risks stream health.

Environmental contamination by fluorinated chemicals, in particular chemicals from the per- and polyfluoroalkyl substances (PFAS) class, has raised concerns around globe because of documented adverse impacts on human health, wildlife, ecosystem quality. Recent studies have indicated that pesticide products may contain a variety meet PFAS definition, including active ingredients themselves. Given pesticides are some most widely distributed pollutants across world, legacy addition into could be widespread wide-ranging implications agriculture food water contamination, as well presence rural environments.

Pesticides pose a threat to the environment, but because of substantial number compounds, comprehensive assessment pesticides and an evaluation risk that they human aquatic life is challenging. In this study, improved analytical methods were used quantify 221 pesticide concentrations in surface waters over time period from 2013 2017. Samples collected 74 river sites conterminous US (CONUS). Potential toxicity was assessed by comparing water standard are considered have adverse effects on health or organisms. The majority use related agriculture, agricultural production varies across CONUS. Therefore, our results summarized region (Northeast, South, Midwest, West Pacific), with expectation crop differences would drive variability use, detection frequency, benchmark exceedance patterns. Although at least 2.5 times higher Midwest (49 kg km-2) than any other four regions West, Pacific, 3 21 average detected 1.5 (n = 25) 8 n 16), potential more evenly distributed.

Continued monitoring research needed improve understanding life.
