摘要

马来西亚的环境空气质量测量被称为空气污染指数(API)。在一定时间内,现有的空气污染指数基本上被定义为六种污染物的分项指标值的最大值。虽然研究表明,长期和短期接触空气悬浮毒物对人体的毒理学影响不同,但API仍然认为这些污染物对人体具有同等的危害影响。因此,本文旨在提出一种新的API,在其计算中包含代表这些污染物不同危险水平的权重。根据2018年马来西亚16个州的六种污染物读数的二级数据,通过结合主观专家意见和客观数据驱动方法获得的权重来计算总权重,从而平衡了评估的两种观点。结果表明,空气动力学直径小于2.5微米的颗粒物(PM2.5)是最危险的污染物,其总重值最高,16个州的API读数分布均为正常。最高和最低的API读数分别发生在2018年8月14日和3月10日。有人认为,新的空气污染指数读数更准确,并能更好地了解马来西亚的空气污染情况。该研究为具体构建空气污染指数提供了新的思路,并为主管部门构建健康环境提供了更全面、更精确的空气质量测量数据。

Construction of Air Pollution Index with the Inclusion of Aggregated Weights of the Pollutants
The ambient air quality measurement in Malaysia is described as Air Pollution Index (API). Basically the existing API for a given period of time is defined as the maximum value of the sub-index values of six pollutants. Although research has shown that long and short term exposure to air suspended toxicants has a different toxicological impact on human, the API still considers these pollutants as having equal hazardous impacts on human. Hence, this paper aims to propose a new API that includes weights representing different hazardous levels of these pollutants in its calculation. Based on secondary data of six pollutants’ readings for sixteen states of Malaysia for year 2018, the aggregated weights were computed by combining both weights obtained from the subjective experts’ opinions and the objective data-driven methods, which balanced both perspectives of evaluations. The results show that the particulate matter with aerodynamic diameter less than 2.5 micrometre (PM2.5) found to be the most hazardous pollutant since its aggregated weight value is the highest and the distributions of the API readings for all sixteen states were found to be normal. The highest and lowest API readings took place on the 14th of August and 10 of March 2018 respectively. It is argued that the new API readings are more accurate and give a better picture about the occurrence of air pollution in Malaysia in particular. This study provides a new insight in constructing API specifically and contributes a more comprehensive and precise air quality measurements to be analysed by the responsible authorities in their efforts towards healthy environment.
