A Study to Assess the Knowledge and Practices Regarding Use of Microplastics and Its Impact on Health and the Environment Among College Students of Kheda and Anand Districts

Abstract

Introduction: Microplastics defined as plastic particles less than 5 mm in size, have become a growing environmental and public health concern. They are widely present in water, food, air, and daily-use products. College students are highly exposed to microplastics through packaged foods, synthetic clothing, and personal care products. Despite increasing exposure, awareness regarding their harmful effects on health and the environment remains limited. Understanding the level of knowledge and practices among college students is essential for planning effective educational interventions.
Methodology: A Non-experimental descriptive research design was adopted for the study. The sample consisted of undergraduate college students selected using a purposive sampling technique. Data were collected using a structured questionnaire including sections on demographic variables, knowledge, and practices related to microplastics. The collected data were analyzed using descriptive statistics (frequency, percentage, mean, standard deviation) and inferential statistics to determine associations.
Results: The findings revealed that 62% of students had inadequate knowledge, while 55% demonstrated poor practices regarding microplastics. The mean knowledge score was 10.25 (SD = 3.85), and the mean practice score was 9.88 (SD = 4.10). A moderate positive correlation (r = 0.58) was found between knowledge and practice. The study findings revealed that a considerable proportion of students had inadequate to moderate knowledge regarding microplastics and their impact. While some students were aware of common sources such as plastic packaging and cosmetics, limited knowledge was observed regarding health risks and environmental consequences. Many participants reported practices that increase exposure, such as frequent use of single-use plastics. A significant association was found between knowledge levels and selected demographic variables.
Conclusion: The study concludes that college students have insufficient knowledge and suboptimal practices regarding microplastics. There is a need for targeted educational programs to enhance awareness and promote environmentally friendly behaviors. Increasing knowledge can help reduce exposure and contribute to better health and environmental outcomes.
