An Assessment of the Ocular Toxicity of Two Major Sources of Environmental Exposure
<p>These data contain information on chemicals released in to the air from burn pits in Iraq (waste disposal areas for US military bases) and the 2023 Ohio train derailment in East Palestine. The goals of the study were to 1) predict the effects of exposure to these chemicals on the ocular surface and 2) to call attention to the relationship between environmental events and long-term damage to the surface of the eye—in particular, dry eye disease, which is a known result of workplace chemical exposures. The study employed in silico methods through the ACD Labs Percepta platform, using data from the European Chemical Inventory and the Registry of Toxic Effects of Chemical Substances to model the chemicals’ probability of ocular irritation. Variables include the names of compounds identified from the burn pits and the train derailment, along with their chemical formulas, simplified molecular input line entry system (abbreviated to SMILES), and probability of causing eye irritation.</p>

Toxic temperatures: Bee behaviours exhibit divergent pesticide toxicity relationships with warming
<p>Climate change and agricultural intensification are exposing insect pollinators to temperature extremes and increasing pesticide usage. Yet, we lack good quantification of how temperature modulates the sublethal effects of pesticides on behaviours vital for fitness and pollination performance. Consequently, we are uncertain if warming decreases or increases the severity of different pesticide impacts, and whether separate behaviours vary in the direction of response. Quantifying these interactive effects is vital in forecasting pesticide risk across climate regions and informing pesticide application strategies and pollinator conservation. This multi-stressor study investigated the responses of six functional behaviours of bumblebees when exposed to either a neonicotinoid (imidacloprid) or a sulfoximine (sulfoxaflor) across a standardised low, mid, and high temperature. We found the neonicotinoid had a significant effect on five of the six behaviours, with a greater effect at the lower temperature(s) when measuring responsiveness, the likelihood of movement, walking rate, and food consumption rate. In contrast, the neonicotinoid had a greater impact on flight distance at the higher temperature. Our findings show that different organismal functions can exhibit divergent thermal responses, with some pesticide-affected behaviours showing greater impact as temperatures dropped, and others as temperatures rose. We must therefore account for environmental context when determining pesticide risk. Moreover, we found evidence of synergistic effects, with just a 3°C increase causing a sudden drop in flight performance, despite seeing no effect of pesticide at the two lower temperatures. Our findings highlight the importance of multi-stressor studies to quantify threats to insects, which will help to improve dynamic evaluations of population tipping points and spatiotemporal risks to biodiversity across climate regions.</p>
