Microplastic Exposure in Everyday Life: An Awareness-Based KAP Study Among the Indian Population
AI summary Read the abstract
A survey of over 350 people across India found that most know plastic pollution is harmful, but far fewer actually change their daily habits to avoid microplastics, tiny plastic bits that can enter our bodies through food, water, and air. This gap between knowing and doing suggests we need better education and stronger policies, not just awareness, to actually reduce our exposure.
Background: Microplastics are emerging environmental contaminants that pose potential risks to human health and ecosystems. Public awareness and preventive behaviours regarding microplastic exposure remain poorly understood in India. Objective: To assess the knowledge, attitudes, and practices (KAP) related to microplastic exposure among the Indian population. Methods: A cross-sectional questionnaire-based study was conducted among 361 participants from 18 Indian states. Data were collected using a pre-tested KAP questionnaire and analyzed using SPSS version 31. Descriptive statistics and Chi-square tests were applied. Results: Most participants were male (59.8%), undergraduate students (62.05%), urban residents (71.2%), and unmarried (83.4%). Awareness of plastic pollution was high, with 93.1% recognizing its harmful effects and 97.2% identifying plastic pollution as a major environmental issue. Most respondents (85.3%) acknowledged that microplastics affect humans, animals, and the environment, while 76.7% correctly identified multiple exposure pathways. Positive attitudes toward reducing plastic use and strengthening regulations were common; however, preventive practices were limited. Overall, 53.5% of participants demonstrated moderate knowledge, 42.7% poor knowledge, and only 3.9% good knowledge. Positive attitudes were observed in 35.5% of respondents, while good practices were reported by only 10.0%. Residence and marital status were significantly associated with attitude scores, whereas marital status was significantly associated with practice scores (p<0.05). Conclusion: Despite relatively high awareness of microplastic pollution, preventive practices remain inadequate. Targeted educational programs, behavioral interventions, and stronger environmental policies are needed to improve public engagement in plastic reduction and exposure prevention.

Surveys of Knowledge and Awareness of Plastic Pollution and Risk Reduction Behavior in the General Population: A Systematic Review
AI summary Read the abstract
This systematic review examines public surveys about plastic pollution awareness and whether that knowledge leads people to change their behavior. Understanding what people know and do about plastic pollution is important because individual actions, like reducing single-use plastic, can meaningfully lower microplastic exposure for both people and the environment.
Consumption Patterns and Health Perceptions Regarding Plastic Pollution: A Cross-Sectional Study Among Nursing Students in India
AI summary Read the abstract
A study of nursing students in India found that even though most knew plastic pollution can harm human health (like raising risks for breathing problems and cancer) and the environment, over a third still used single-use plastics daily anyway, mostly because it's convenient. This gap between knowing and doing matters because it shows that just understanding the risks isn't enough to change habits — even among future healthcare workers who will one day teach others about health risks like plastic and microplastic exposure.
"Assessment of Knowledge and Practice Regarding Plastic Bag Usage Among Women in Nellikuzhy Panchayat: A Community-Based Cross-Sectional Study"
AI summary Read the abstract
A study of 60 women in a Kerala community found that while most had decent habits around using and disposing of plastic bags, their actual knowledge about plastic's health and environmental risks was only average — suggesting people may be doing some things right without fully understanding why. This gap matters because plastic waste breaks down into microplastics that can contaminate food, water, and soil, eventually making their way into our bodies, so better public education could help households make smarter choices, like switching to reusable cloth bags, to cut down on this exposure.
From Awareness to Action: A Critical Review of Public Knowledge and Behavioral Gaps in Addressing Plastic Pollution
AI summary Read the abstract
This review examined why public awareness of plastic pollution has not translated into meaningful behavior change. Researchers found that most people focus on visible plastic items like bottles and bags but have limited knowledge about microplastics from clothing or tires. Key barriers to action include convenience, cost, social norms, and distrust in recycling systems, suggesting that education alone is insufficient without strategies targeting specific behavioral changes.
The degree of awareness of the risk of microplastic particles/people’s perception in taking preventive measures for this type of risk
AI summary Read the abstract
This study surveyed public awareness of microplastic risks and perceptions around taking protective measures, finding that knowledge levels were variable and that most people had limited understanding of exposure routes and health implications. The authors call for targeted public communication campaigns to increase risk awareness.
