The Novel Study On Arsenic Contamination, Health Risk, and Approaches to Its Mitigation From Water Resource of a Developing Country: A potential review

The pollution and contamination by arsenic (As) in the water resources is a worldwide concern due to its adverse toxic effects on the environment and public health. The current study aimed to investigate arsenic levels in the groundwater system with the possible health risk, and sustainable mitigation strategies. The data on arsenic in the water system were collected from the Web of Science and Scopus databases. The published data showed that arsenic concentration (0.0002-19.0 mg/kg) in the water system in Bangladesh was higher than the permissible standards and data from other countries, indicating severe contamination of water resources by arsenic. The study concluded that the water resource in Bangladesh is not safe for human consumption. The review has also identified the research gaps in various strategies for controlling the arsenic problem and their impact on the ecosystems. The present study suggested future research directions on sustainable intervention, impacts assessment of arsenic on humans, and formulating existence policy that helps to combat arsenic contamination.
