A Descriptive Study on Knowledge Regarding the Impact of Plastic Pollution on Human Health and Ecosystems Among High School Students in Durgapur

Abstract

Background: Plastic pollution has emerged as one of the most pressing global challenges, creating significant risks to both human health and ecosystems. The rapid rise of single-use plastics and their breakdown into microplastics have led to contamination of land, water, and air. These pollutants disrupt food chains, harm biodiversity, and expose humans to hazardous chemicals through ingestion, inhalation, and contact. Although awareness has grown, gaps in knowledge persist, especially among young learners who are the future stewards of the environment.  

Objective: To assess the level of knowledge and awareness among high-school students regarding the impact of plastic pollution on human health and ecosystems, and to identify factors influencing their perceptions.

Method: A descriptive cross-sectional study was conducted among students aged 14–18 years from selected schools in Durgapur, using systematic sampling. Data were collected through a structured questionnaire covering knowledge of plastic sources, environmental consequences, and health risks. Influencing factors such as environmental education, media exposure, and socio-economic background were also explored.

Results: The study revealed varied knowledge levels. While most students recognized plastic pollution as an environmental concern, only a smaller proportion understood its specific health consequences, including exposure to harmful chemicals and food-chain contamination. Awareness of ecological issues such as biodiversity loss and marine life threats was limited. Students who had access to environmental education programs or campaigns demonstrated greater awareness and were more inclined toward eco-friendly practices such as reducing plastic usage and recycling. Nevertheless, their overall readiness to take action was moderate.

Conclusion: High school students demonstrated a basic understanding of plastic pollution but lacked deeper insights into its health and ecological impacts. Strengthening school-based environmental education is essential to bridge knowledge gaps and encourage sustainable practices among youth.
