Coal ash contains numerous contaminants and is the focus of regulatory actions and risk assessments due to environmental spills. We exposed Daphnia magna to a gradient of coal ash contamination under high and low food rations to assess the sublethal effects of dietary exposures. Whereas exposure to contaminants resulted in significant reductions in growth and reproduction in daphnids, low, environmentally relevant food rations had a much greater effect on these endpoints.

饮食中食物摄入的粉煤灰污染物对大水蚤生长和繁殖的影响。

煤灰含有多种污染物，是环境泄漏造成的监管行动和风险评估的重点。我们在高和低食物配比下，使水蚤受到了一定程度的粉煤灰污染，以评估饮食暴露的亚致死作用。暴露于污染物导致水蚤的生长和繁殖显着减少，而与环境相关的低食物定量对这些终点影响更大。环境毒性化学2020; 39：1998–2007。©2020 SETAC
