Linking Science and Administration: Local Ozone Management and Prevention Framework in Malaysia

Abstract

Ozone at ground level was proven to have causal relationships with ill health of human. Managing air pollution was carried out mainly as federal initiatives. Local ground ozone management has not been given adequate emphasis. There were studies conducted to path basic understanding of the ozone critical conversion point (CCP) which explain ozone transformation behaviour from its precursors. The interactions diurnally between nitrogen oxides, temperature and sunlight, have determined photochemical ozone rates. The obtained CCP lies in between the critical conversion time (CCT) which is from 8.00 to 11 a.m. as been determined using composite diurnal plot method which has open the possibility to use photochemical ozone rates to determine CCT. This crucial information could be further used to determine exact rates of ozone photochemical transformations from its precursor. Understanding the behaviour of ozone transformation should lead to local ozone management plan being drawn. The authorities could adopt the proposed framework of local ozone management and prevention in Malaysia for more effective actions.
