Knowledge and Perception of Plastic Waste Disposal Practices in Opobo/Nkoro Local Government Area, Rivers State
AI summary Read the abstract
A survey of 389 residents in three riverine communities in Rivers State, Nigeria, found that most people knew proper ways to dispose of plastic waste and viewed plastic pollution as a health risk. However, 83.5% still disposed of plastic waste improperly, with education level linked to awareness and views on risk.
Background: Improper plastic waste disposal poses significant environmental and public health risks, particularly in riverine communities where plastic pollution threatens aquatic ecosystems and water resources. This study assessed awareness and perception of plastic waste disposal as an environmental health risk among residents of Opobo/Nkoro Local Government Area, Rivers State, Nigeria. Methods: A descriptive cross-sectional survey was conducted among residents of three selected communities: Nkoro, Kalibiama and Opobo Town. Data were collected using a structured, interviewer-administered questionnaire. Of the 400 questionnaires administered, 389 were completed and analysed, yielding a response rate of 97.25%. Data were analysed using IBM SPSS Statistics version 25. Descriptive statistics and binary logistic regression were used to summarise responses and identify factors associated with awareness and perception. Statistical significance was set at p < 0.05. Results: Most respondents were male (51.4%), and 46.0% had tertiary education. Overall, 86.9% demonstrated high awareness of proper plastic waste disposal practices, while 13.1% had low awareness. Furthermore, 92.5% had a positive perception of plastic waste as an environmental health risk. Educational attainment was significantly associated with high awareness, with respondents who had secondary education (AOR = 2.35; 95% CI: 1.30– 4.25) and tertiary education (AOR = 4.80; 95% CI: 2.65–8.69) having higher odds of awareness. Similarly, secondary and tertiary education were associated with positive risk perception. Despite these favourable findings, 83.5% of respondents practised improper plastic waste disposal. Conclusion: Residents demonstrated high awareness and positive risk perception, yet improper disposal remained widespread. Interventions should therefore extend beyond general awareness campaigns to improve waste collection services, strengthen community-based waste management and promote practical, accessible disposal alternatives, particularly among farmers and fishermen and residents with limited formal education.

Environmental Health Risks and Community Awareness About Microplastic Pollution in Coastal Estuarine Systems of Andoni River Estuary, Rivers State, Nigeria
AI summary Read the abstract
A survey of 399 residents near the Andoni River Estuary in Nigeria found strong awareness of health risks from microplastics, especially in fish, drinking water and the environment. Education, occupation, income and years lived in the area shaped these views, while age and gender did not, and understanding of long-term and breathing-related risks was weaker.
Consumers’ Attitude and Plastic Waste Disposal Behavior in Southeast, Nigeria
AI summary Read the abstract
A study in Southeast Nigeria found that people's attitudes, social pressures, and environmental knowledge strongly shape how they throw away plastic waste, even though most people already know plastic harms the environment. This matters because poorly managed plastic waste often ends up polluting land and water, breaking down into microplastics that can enter our food and water supply. The researchers suggest that public awareness campaigns and better waste infrastructure, combined with community and cultural influence, could encourage healthier disposal habits and reduce plastic pollution's risks to both the environment and human health.
