Research on chlorophyll-a concentrations in freshwater lakes of Pavlodar region

Abstract

Freshwater ecosystems play a crucial role in maintaining ecological balance and ensuring human well-being. However, these ecosystems are increasingly threatened by anthropogenic activities. Pavlodar region has undergone rapid industrialization and urbanization, impacting its pristine lakes.

This article is part of a doctoral study on lakes located equidistant from each other, aimed at determining the chlorophyll-A levels in the lakes of Pavlodar region.

Seven lakes were purposefully selected from the numerous lakes in the region, considering various anthropogenic impacts. Water samples were collected in the spring of 2022.

A comparative assessment revealed significant differences in chlorophyll levels observed in several water bodies. The study identified polluted water basins in the region, highlighting critical areas that require urgent attention for environmental conservation.

The conducted analyses indicate possible processes of vegetation degradation and flooding, leading to a decrease in dissolved oxygen and potential environmental consequences. The obtained results underscore the importance of continuous monitoring and effective management strategies to preserve the ecological integrity of the studied water bodies.

This study provides valuable information on the ecological status of lakes in Pavlodar region and highlights the impact of both natural and anthropogenic factors on water quality. The findings underscore the need for targeted environmental efforts.
