WATER QUALITY INDICATORS IN TEMPORARY ENVIRONMENTS OF THE ATLANTIC FOREST

Abstract

Temporary pools are environments formed by river flooding and rainwater that support a wide variety of species, including some at risk of extinction. While chemical compounds are naturally found in aquatic habitats, the increased presence of these compounds due to human activities is concerning. This study aimed to assess water quality indicators in temporary coastal ecosystems of the Atlantic Forest. Samples were collected from January to May 2024, and concentrations of ammonia, phosphate, nitrate, and nitrite were measured. The results, compared to the limits established by CONAMA, indicated elevated concentrations of ammonia and phosphate, suggesting possible contamination from sewage and putting at risk the life forms that inhabits in these environments.
