Public Perception of Air Pollution in Malaysia Before and After Movement Control Order: A Case Study

Abstract

Air pollution is an environmental risk assessment method conducted in this journal review. Air pollution data review before the implementation of the Movement Control Order (MCO) and after was answered by respondents. These respondents were collected randomly without selection of demographic ranges from non-university students in Malaysia within a period of 47 days. The data was then interpreted based on their demographic range, reviews, knowledge and awareness. It was to find out that there was no significant difference between demographic changes such as occupation, gender and race. Generally, it is to find that the air pollution (K et al., 2018) problem decreases after MCO where respondents have more positive opinions. Respondents also act neutrally when facing economic importance in environmental problems. However, respondents are active and positive in helping the environment personally or individually rather than collaborating with the country’s efforts in terms of financial contribution. The study is important to study the effect of air pollution in Malaysia, especially Selangor and KL as a city, to assess the pollution index and reduce ecological toxicology effects on affected areas. More studies need to be discovered for risk assessment of organisms in these involved areas as well. The primary objective of this study is to assess public perceptions of air pollution in Malaysia before and after the MCO (Turrentine & Mackenzie). The research also examines how demographic factors such as age, occupation, and race influence these perceptions.
