Scientometric analysis on persistent organic pollutant in aquatic system from 1984 -2025

Abstract

Persistent organic pollutants (POPs) are long-lasting synthetic chemicals that contaminate aquatic systems through agricultural runoff, industrial effluents, atmospheric deposition, and wastewater discharge. Their persistence, lipophilicity, and resistance to degradation enable long-range transport and extensive bioaccumulation in aquatic organisms, ultimately exposing humans through seafood consumption. These pollutants are linked to reproductive disturbances, metabolic disruption, neurological impairment, and elevated chronic disease risks. This scientometric analysis examines global POP research in aquatic environments from 1984 to 2025 (data retrieved from scopus and WOS) evaluating publication growth, influential authors and institutions, collaboration patterns, and keyword evolution. Research output rose sharply after 2001, driven by increasing environmental awareness and advancements in analytical technologies. Keyword mapping highlights major themes such as bioaccumulation, toxicity, environmental monitoring, and emerging contaminants like microplastics. Collaboration trends show strong contributions from small and medium research groups, with citation impact influenced more by publication quality than quantity. Overall, POP research exhibits rapid interdisciplinary expansion and growing global relevance.
