Kinetics of Environmental Degradation Focus on Pollutant Breakdown and Remediation
Keywords:
Environmental degradation, Pollutant kinetics, Bioremediation, Reaction kinetics, Remediation strategiesAbstract
This study explores the kinetics of environmental degradation with a focus on pollutant breakdown and remediation strategies. As pollution from industrial, agricultural, and domestic sources continues to burden natural ecosystems, understanding how contaminants degrade over time has become crucial for effective environmental management. The research examines both abiotic and biotic degradation pathways, analyzing factors such as temperature, pH, microbial activity, and light that influence the rate and extent of pollutant transformation. Emphasis is placed on key kinetic parameters, including reaction order and half-life, to evaluate pollutant persistence in various environmental compartments. Additionally, the study assesses conventional and emerging remediation techniques—such as bioremediation, chemical oxidation, and nanotechnology—through the lens of degradation kinetics. By linking kinetic behavior to remediation efficiency, the research offers insights that support the design of targeted, cost-effective cleanup approaches and contributes to a deeper understanding of contaminant dynamics in support of sustainable environmental practices.
