The Effects Of Pollution On Aquatic Life In Freshwater Ecosystems

Abstract

Aqueous systems that serve essential biodiversity needs and ecological services face growing danger from agricultural-related contamination. Pesticides function as a major pollution source which endangers aquatic wildlife populations while harming ecosystem health. This review investigates macroinvertebrates as indicators of freshwater ecosystem condition particularly in detecting pesticide water contamination. Due to their sensitivity to contaminants macroinvertebrates deliver important information about short-term and long-term environmental changes that help determine ecosystem degradation. The effectiveness of macroinvertebrates in monitoring faces obstacles from their species-specific reactions and their changing population patterns. Studies have proven that pesticide contamination results in population reduction of macroinvertebrates which propagates through food chains to harm fish and amphibians and consequently harms entire ecological systems. When pesticides act along with other environmental pressures from climate change and reduced habitats they create dense cumulative impacts on ecosystems. The existing biological monitoring systems remain useful but show problems because scientists follow different procedures and the regions lack unified monitoring procedures. Standards and better monitoring procedures are required including molecular analysis solutions with remote sensing and expanded chemical analysis. Research initiatives should concentrate on identifying combined pollution effects between multiple contaminants while establishing combined biological chemical and physical monitoring methods. The sustainability of freshwater ecosystems depends on both full environmental monitoring data and stronger pesticide controls to create effective management solutions which must be implemented.
