Comprehensive and Understanding of PM2.5 among Thai High School Students

/in /by

The majority of Thai people prefer to spend their time participating in outdoor activities. However, Thailand is considered a polluted country, and Bangkok is ranked as the most polluted city in the country. Younger generations faced an issue of lacking awareness about PM2.5. As a consequence of encountering particulate fine particles, individuals may be at high risk of developing respiratory and cardiovascular diseases. In addition, none of the researchers have ever conducted a survey researching the comprehensiveness and understanding of high school students in Thailand about PM2.5. Hence, this research aims to analyze and determine understanding among Thai high school students in Thailand. The research was conducted through an online survey consisting of 21-multiple choice questions. With 133 individuals participating in the survey, the mean score was rounded up to 13.65, illustrating the comprehension level of high school students to be on an average scale. From analyzing the correlation between the two variables, the F value was 0.27. According to mean value, the most prominent fundamental reasons for having average knowledge on fine particles may be a consequence of not including the topic into school’s syllabus and low promotion in the media, such as newspapers and social media. Thus, this research aims to raise awareness, concern, and comprehension among high school students about the effects of PM2.5.

A Systematic Review on Long Term Variation of Carbonaceous Aerosols in Pm2.5 at Different Sites of “Delhi” Capital City of India

Being a criteria pollutant Fine Particulate Matter (PM2.5) exposure  not only affects human health but also deteriorates environmental health, air quality and artifacts. Traffic, biomass burning and industrial activities are important contributors to ambient fine particulate matter in major cities of the world. Therefore, to reduce fine particulate matter pollution and the considerable disease burden it causes solutions to bring down ambient fine particulate matter are needed. Carbonaceous aerosols are found to be a significant contributor to fine particulate matter. These aerosols are subdivided into organic carbon and elemental carbon. Elemental carbon is released from primary sources whereas organic carbon can be released either from primary or secondary sources. This paper presents a comprehensive critical review of the assessment of fine particulate matter and its carbonaceous content in the past decade on different sites in New Delhi, the capital of India. Considerable health effects of particulate pollution have also been discussed in the paper. Critically reviewed data showed a non – significant increase in the trend of particulate matter concentration. It was also shown through the data of each study that the emission standards of WHO exceeded by 15 times whereas for NAAQS they exceeded by 5 times respectively.
