Mercury is a toxic heavy metal that is naturally present in the environment, but can also be released through industrial processes and human activities. Research on mercury often focuses on its environmental impact, particularly its bioaccumulation in aquatic ecosystems and its effects on wildlife and human health. This research area also explores methods for monitoring and reducing mercury pollution, as well as developing technologies for mercury remediation. Overall, the goal of mercury research is to better understand its behavior in the environment and minimize its harmful effects on living organisms.
