Environmental Pollution and Its Impact on Aquatic Ecosystems with Special Reference to Ponds in Meerut Region

Abstract

Environmental pollution has emerged as one of the most serious hreats to freshwater ecosystems, particularly ponds, which support rich biodiversity and provide essential ecological services. Rapid urbanization, agricultural intensification, industrial development, domestic sewage discharge, and improper solid waste management have significantly degraded pond ecosystems in the Meerut region of Uttar Pradesh. Increasing concentrations of nutrients, pesticides, heavy metals, plastics, and organic pollutants have adversely affected water quality, aquatic biodiversity, ecosystem productivity, and ecological stability. Ponds serve as important habitats for fish, amphibians, aquatic plants, plankton, macroinvertebrates, and numerous microorganisms that contribute to nutrient cycling and ecological balance. The present study investigates the impact of environmental pollution on aquatic ecosystems with special reference to ponds in the Meerut region through a comprehensive analytical review of recent scientific literature and regional environmental conditions. The findings indicate that deteriorating water quality has resulted in eutrophication, reduced dissolved oxygen, biodiversity loss, fish mortality, proliferation of invasive species, and disruption of aquatic food webs. The study further highlights sustainable management strategies including wastewater treatment, pollution control, ecological restoration, public awareness, and community participation for conserving pond ecosystems. The study concludes that integrated environmental management and scientific conservation measures are essential for protecting freshwater biodiversity and maintaining ecological sustainability in the Meerut region.
