Description of the primary Loreto-coca river contamination through the measurement of physicochemical parameters.

Abstract

The main objective of this article is to describe the pollution in the main Loreto-Coca rivers using physicochemical parameters. Our analysis is focused on the Orellana province and examines the Suno, Napo, Coca, and Payamino rivers, which are adversely impacted by oil and mining activities. These activities result in toxic and chemical residues, such as heavy metals and other contaminants. Samples were collected following the INEN 2176 standard to do this. We could evaluate parameters such as pH, dissolved oxygen, conductivity, turbidity, nutrients (nitrates, phosphates), heavy metals, and COD using laboratory equipment and specific techniques and methods. The level of pollution was determined by comparing these results with permissible limits. Therefore, based on the comparative results obtained, environmental education is crucial for raising awareness about the importance of protecting and conserving water as a vital resource. Conducting these studies provides essential information for taking preventive and corrective measures and monitoring and addressing identified issues to safeguard public health and the environment. Keywords: pollution, water, rivers, sample, standard, physicochemical parameters.
