Public Awareness and Attitudes Toward the PM2.5 Problem

Abstract

This study aims to analyze the awareness, attitude, protective behavior, and policy support of Thai citizens regarding PM2.5 air pollution. A quantitative research approach was employed, with data collected from 600 respondents using a structured questionnaire. Descriptive statistics and correlation analysis were used for data interpretation. The results indicate that the level of awareness of PM2.5 among the public was moderate to high (mean score = 3.8/5), while their attitude toward air pollution control measures was highly positive (mean score = 4.2/5). However, protective behavior remained at a moderate level (mean score = 3.5/5), with 72% regularly wearing masks and only 48% using air purifiers. Statistical analysis revealed a significant positive correlation between awareness and protective behavior (r = 0.68, p < 0.01), as well as between attitude and policy support (r = 0.75, p < 0.01). These findings suggest that enhancing public awareness and attitude could contribute to improved protective behavior and stronger support for government policies. The study highlights the importance of effective environmental communication strategies and policy implementation to mitigate the PM2.5 crisis sustainably.
