Abstract: Bat guano serves as a potential bio-indicator tool for accessing the heavy metals contamination level in bats. Such a non-invasive tool also permits an assessment of the plausible risks of heavy metal pollution among wildlife, humans, and the ecosystem. The study provides the first assessment of metals such as mercury, chromium, copper, manganese, and nickel in bat guano from the Indian state of Kerala, thus providing us valuable information on the quality of the environment.
