Fragments were the most abundant MP morphology and were the primary form driving differences in total MP concentrations among the sites. Flow velocity had the greatest impact on plastic concentrations in the sediment, and the accumulation of MPs in surface water increased as water depth decreased. The highest MP concentrations were found at pipe outfalls in both surface water and sediment compared with surface drains. The watershed with more agricultural and forested landcover had higher MP concentrations downstream of both types of drainage infrastructure than the more developed urban watersheds.

This study aimed to evaluate the chronic effects of a mixture of MPs on two model soil organisms, the earthworm Eisenia andrei and the springtail Folsomia candida. The MP mixture was composed of polymers and shapes frequently found in agricultural soils amended with sewage sludge, including HDPE and PP fragments, and PES fibres. The organisms were exposed in LUFA 2.2 soil to MP concentrations of 0-1% dry soil for E. andrei, and 0-5% for F. candida. This study shows that particle ingestion by E. andrei was proportional to MP exposure levels, and the size distribution taken up was similar to that observed in the exposure medium, suggesting non-selective uptake behaviour. In contrast, very low ingestion levels of MPs were found for F. candida, even at the highest test concentration. No significant effects were found on survival, growth or reproduction of E. andrei. However, significant adverse effects were found on the reproductive output (number of juveniles) and juvenile dry weight for F. candida, with a reduction of approximately 30% in both endpoints at the highest test concentration, and calculated NOECs of 0.4% and 1%, respectively. These adverse effects may have been caused by changes in soil properties, mobility reduction, and/or the presence of plastic additives, instead of MP uptake. The comparison of MP exposure concentrations in soils obtained from the literature with the threshold concentrations derived for F. candida indicates insignificant environmental risks at current exposure levels.</p>","PeriodicalId":11793,"journal":{"name":"Environmental Toxicology and Chemistry","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144539604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, pesticide concentrations in surface waters are highly variable and often missed by traditional grab sampling methods, which typically fail to capture transient peaks and hydrophobic compounds that partition into non-water matrices. Time-integrated monitoring approaches, such as biofilm sampling using periphytometers, offer a promising alternative. Despite this, uncertainties remain about how biofilm processing methods affect pesticide quantification, and whether replicate periphytometers are necessary to improve monitoring accuracy. To address these questions, water and biofilm samples were collected from six stream sites in Southern Ontario. Biofilm samples were split and processed using either freeze-drying or centrifugation to evaluate the effect of sample preparation on pesticide detection. All samples were analyzed for ∼500 pesticides. Freeze-dried biofilm consistently yielded higher pesticide detection frequencies and concentrations compared to centrifuged samples, indicating that freeze-drying is a more effective processing method for capturing pesticide residues in biofilm. These findings highlight the importance of standardizing biofilm processing methods to improve monitoring reliability. To evaluate the need for replication, six periphytometers were deployed in parallel at a single stream site. Biofilm samples from each replicate were analyzed for pesticide presence. Pesticide detection profiles were highly consistent across replicates (P > 0.05) in two separate sampling events, suggesting that a single periphytometer is sufficient to characterize site-level pesticide exposure at our stream site. Together, these results provide guidance for improving pesticide monitoring programs by recommending freeze-drying for biofilm processing and supporting the continued use of single periphytometer deployments, which are more feasible for routine monitoring without compromising data quality.</p>","PeriodicalId":11793,"journal":{"name":"Environmental Toxicology and Chemistry","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144526981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although several studies have implicated pesticides as a contributing factor to their population declines, our understanding of monarch exposure levels in nature remains limited. In January 2024, a mass mortality event near an overwintering site in Pacific Grove, California, USA, provided an opportunity to analyze dead overwintering monarch butterflies for pesticide residues. Ten recently deceased butterflies were collected and analyzed using liquid and gas chromatography with tandem mass spectrometry (LC-MS/MS and GC-MS/MS). We identified a total of 15 pesticides and associated metabolites in the butterflies, including 8 insecticides (plus 1 associated metabolite), 2 herbicides (plus 2 associated metabolites), and 2 fungicides. On average, each monarch butterfly contained 7 pesticides, excluding transformation products if the parent compound was also detected. Notably, three pyrethroid insecticides-bifenthrin, cypermethrin, and permethrin-were consistently detected at or near each chemical's lethal dose (LD50). Bifenthrin and cypermethrin were found in every sample, while permethrin was present in all but two samples. The average concentrations of these insecticides were 451.9 ng/g dry weight (dw) for bifenthrin, 646.9 ng/g dw for cypermethrin, and 337.1 ng/g dw for permethrin.

The observed effect concentrations for F. candida are within the predicted environmental concentrations for agricultural use of chlorfenapyr and therefore indicate an immediate hazard towards Collembola.

However, interpretation of stress responses can be complicated by multiple interacting factors (e.g., individual development, evolved physiological tolerance to stressors) which alter biomarker expression. To better understand the relative influences of these factors, we used wood frog (Rana sylvatica) populations with known variation in ontogenetic and contaminant tolerance traits. We examined how both individual ontogenetic traits and population-level tolerance traits influence oxidative stress responses under baseline and NaCl-contaminated environmental conditions. We exposed tadpoles from six noninteracting populations with known variation in ontogeny, pesticide tolerance, and NaCl tolerance to either baseline or NaCl-contaminated conditions and evaluated five biomarkers of oxidative stress. We found that individual body mass was a significant predictor of two oxidative stress biomarkers (catalase and glutathione reductase) in baseline conditions only, such that greater mass predicted lower enzyme activity. Separately, population pesticide tolerance was a significant predictor of one oxidative stress biomarker (glutathione peroxidase) in NaCl-contaminated conditions only, such that higher pesticide tolerance predicted higher enzyme activity. Our results demonstrate that both individual traits (mass) and population history (selection for pesticide tolerance) can explain some variation in oxidative stress biomarkers. However, these associations are largely dependent upon the environmental conditions experienced.

While SeqAPASS can rapidly generate predictions of species susceptibility in terms of a \"yes\" or \"no\" output, there is a growing interest in deriving more quantitative metrics for enhancing these predictions. To do this, a bioinformatics workflow was developed that combined SeqAPASS results with molecular docking and molecular dynamics (MD) simulations. This workflow was developed using transthyretin (TTR) and a per- and polyfluoroalkyl substance (PFAS), with an emphasis on perfluorooctanoic acid (PFOA) as it is known that PFOA binds to TTR in humans and other experimental animals. This workflow was applied to generate quantitative information as additional lines of evidence for the conservation of the PFOA-TTR interaction across species. The SeqAPASS analysis predicted hundreds of species as susceptible based on conservation of the PFOA-TTR interaction (Level 1: 952 species, Level 2: 976 species, Level 3: 750 species). Predicted TTR structures from a subset of the species predicted as susceptible by SeqAPASS were used in molecular docking and MD simulations. The simulations supported that Lysine-15 is a key residue for the PFOA-TTR interaction. Quantitatively there was no significant difference in the species tested regarding their predicted binding affinities or other metrics specific to the chemical-protein interactions. These results demonstrated that the interaction between TTR and PFOA is likely conserved across various vertebrate taxonomic groups.

The aim of this study was to assess the applicability of adapted simulation approaches to approval procedures. Herein, a preliminary PELMO-generated simulation was compared against an experimental setup to identify the key parameters and optimization thereof of biocide soil distribution. The 5-day soil column experiment was performed to address the higher application dilutions of biocides. Based on the adapted parameters in the preliminary findings a 90-day experimental study was compared against the corresponding simulation. Experimentally, the presence of hydrophobic and slowly degradable biocides in soil layers up to 25 cm was observed, which was in contrast to maximum of 5 to 7.5 cm of soil layer depth identified via the PELMO simulation. Furthermore, weather events, such as dry periods or heavy rain events, were shown to influence the biocide distribution, which is a parameter excluded from the simulation. The main finding herein was that adjustment of the dispersion length standalone is not sufficient to approximate the biocide application scenario. The adjustment of the adsorption parameter should be adapted in the simulation, accompanied by the water-substance application. Finally, these adaptions should be evaluated against a field study since a laboratory set-up does not represent all aspects of natural weathering events.</p>","PeriodicalId":11793,"journal":{"name":"Environmental Toxicology and Chemistry","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144511715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
