Summary: Bird feathers have been commonly used to assess environmental contamination, but little research has been done on the contamination of neonicotinoids in birds' feathers. This study found that clothianidin, a neonicotinoid insecticide, can be absorbed and deposited in birds' feathers. The findings confirm the relevance of using feathers to biomonitor the presence of neonicotinoids.

Summary: The study found that under semi-field conditions, foraging activity of honey bees on mustard bloom significantly reduced after thiamethoxam spray, with a significant increase in bee mortality. Under field conditions, bee activity remained low up to the 12th day after spray, with less pronounced effects on bee mortality and colony parameters. Thiamethoxam was proven to be toxic to both adult and larval stages of Apis mellifera based on LD50 tests.

Summary: This study evaluated the chronic toxicity and risk of clothianidin to nontarget soil invertebrates through toxicity assays and risk assessment. Results showed higher toxicity of clothianidin to collembolans, lower toxicity to earthworms, and significant risk to soil invertebrates. Data from this study can contribute to establishing more reliable protection thresholds for clothianidin in soils.

Summary: Providing clean water to honey bees can help reduce bee mortality associated with pesticides and improve colony health, but waterers did not reduce worker mortality or increase overall colony weight in the study. However, waterers provided bees with water containing fewer pesticides and reduced the risk of drowning compared to natural sources of water.

Summary: The study investigated the effects of neonicotinoid pesticide Imidacloprid on Aphis gossypii using high-throughput non-targeted metabolomics, revealing sublethal and lethal effects at LC10 and LC90 doses. Changes in metabolic pathways showed high energy consumption, excitotoxicity, and oxidative stress in both LC10 and LC90 groups, with PD detected only in the LC90 group. Non-targeted metabolomics successfully revealed the physiological effects of neonicotinoid pesticide stress on A. gossypii.

Summary: Insect pest management heavily relies on neurotoxic insecticides, with low doses of neonicotinoids like clothianidin potentially enhancing various life traits in target pests. Residual accumulation of these insecticides may modify chemical communication through neuronal and behavioral responses. High-throughput RNAseq and proteomic analyses revealed that exposure to clothianidin induced significant changes in gene and protein expression in moth brains, potentially leading to enhanced responses to environmental stressors.

Summary: The study evaluated the distribution of neonicotinoid IMI in a songbird species and its physiological effects, showing IMI absorption and elimination in tissues, as well as impacts on hematological, genetic, and enzymatic parameters. Treatments altered cholinesterases and GST activity, with the suggestion of using plasma GST inhibition as a non-lethal biomarker for IMI exposure in wild birds. Valuable tools for bird conservation in agroecosystems were provided.

Summary: The study investigated the impact of neonicotinoids exposure on the directional orientation of migratory monarch butterflies. Despite detectable levels of clothianidin in milkweed tissue consumed by caterpillars, there was no evidence that clothianidin influenced the flight behavior or orientation of adult butterflies during migration. Preliminary results suggest that early exposure to clothianidin does not affect the directed flight of adult migratory monarch butterflies.

Summary: Exposure to thiacloprid was found to have negative impacts on the male reproductive system, resulting in decreased sperm count, telomere defects, reduced lumen size, altered gene expression, and changes in chromatin-modifying enzymes. These effects could lead to deleterious effects on male spermatogenesis.

Summary: The use of neonicotinoids poses a threat to honey bees, and despite the EU banning certain neonicotinoids, exposure to these chemicals is still a concern. Research shows that sublethal concentrations of neonicotinoids can lead to oxidative stress and impair the immune defense of honey bees.

Summary: This study examined the sublethal effects of niclosamide on Pomacea canaliculata, an invasive aquatic snail. The results showed that niclosamide had damaging effects on muscle fibers and acinar vesicles, and changed the metabolic mode of the snail. Transcriptome analysis identified differentially expressed genes in various tissues, providing insights into the molecular mechanisms of sublethal effects.

Summary: PPCPs are released into aquatic environments via untreated sewage, wastewater treatment plants, landfill leachate, and can affect aquatic life through sublethal and lethal effects, although some studies suggest PPCPs are non-toxic to aquatic organisms at environmentally relevant concentrations. There is wide variation in reported toxicity levels and limited consensus in the academic literature, emphasizing the need for more research on chronic toxicity of PPCPs at environmentally relevant concentrations.

Summary: Research shows that road salt has negative effects on freshwater organisms, but may have positive effects on phytoplankton and periphyton. The rate of salt release, whether gradual or abrupt, does not appear to significantly impact organism responses. Additional research on how road salt pollution affects freshwater communities at different frequencies and magnitudes is needed.

Summary: PFAS are contaminants of concern due to their persistence, potential to bioaccumulate, and toxicity. Limited data on dietary PFAS uptake and adverse effects in terrestrial species hinder ecological risk assessment. Laboratory experiment on tiger salamanders showed PFOS resulted in biomagnification, while PFAS altered growth and body condition without increasing liver size at environmentally relevant doses. The results demonstrate the impact of dietary exposure and accumulation of PFAS on amphibians' fitness-related traits and trophic transfer in terrestrial food webs.

Summary: This research highlights the significant and diverse impacts that pesticides have on phytoplankton and zooplankton communities in ponds. Insecticides were shown to have top-down effects on phytoplankton composition and abundance, while herbicides reduced total phytoplankton abundance. Understanding these effects is crucial for better risk assessment and mitigation strategies in the face of increasing pesticide pollution worldwide.

Summary: Per- and polyfluoroalkyl substances (PFAS) are contaminants that can negatively affect the health and development of amphibians. The sensitivity to PFAS varies among species, with longer developmental species being more susceptible. In areas with high levels of PFAS contamination, certain species may experience sublethal effects.

Summary: In this study, the acute toxicity of two widely used fungicides, chlorothalonil and pyraclostrobin, on six North American larval amphibian species was examined. The results showed that pyraclostrobin was approximately 3.5x more toxic than chlorothalonil, with estimated LC50 values ranging from 5-18 μg/L for pyraclostrobin and 15-50 μg/L for chlorothalonil. Salamanders were found to be 3x more sensitive to pyraclostrobin than anuran species and equally as sensitive to chlorothalonil. The estimated LC50 values fell within the expected environmental concentration, indicating potential direct mortality in these species. Additional research is needed to assess the overall risk of these fungicides to amphibians and their aquatic habitats.
