Heavy metal pollution in aquatic habitats endangers both aquatic life and human health. Lead, cadmium, mercury, and arsenic, among others, are released into aquatic habitats as a result of a wide range of human activities, with far-reaching and perhaps irreversible consequences for aquatic ecosystems and the natural world at large. In aquatic environments frequented by humans, Garra gotyla serves as a sentinel species, reporting on the state of the local ecology and warning of any possible threats to the human communities that depend on those waters. This research was carried out to determine how much heavy metals had built up in the various tissues of the Garra gotyla fish. Manganese, iron, chromium, zinc, lead, cadmium, and nickel concentrations in the fish samples were measured using an atomic absorption spectrophotometer. Heavy metal concentrations vary widely between fish species and tissue types.
