Foodweb dynamics affect arsenic speciation and bioaccumulation in lakes affected by gold mines

Abstract

Paper summary generated by OpenAI: This study investigates the impact of food web dynamics on arsenic speciation and bioaccumulation in aquatic ecosystems. Utilizing a combination of field sampling and laboratory experiments, the research reveals how variations in trophic interactions influence arsenic transformation processes and its subsequent uptake by organisms. The findings demonstrate that changes in species composition and abundance can significantly alter arsenic bioavailability, with implications for ecological health and risk assessment. This work highlights the importance of considering food web structures when evaluating the environmental fate of contaminants like arsenic.
