Market Impact
on 30 September, according to the Malaysian Air Pollutant Index Management System (APIMS). The data indicates a widespread deterioration in air quality, with multiple states reporting significant pollution levels early in the day.
Johan Setia in Selangor recorded the highest IPU reading at 176, followed by Cheras in Kuala Lumpur at 173 and Nilai in Negeri Sembilan at 171. Other areas that registered unhealthy levels included Shah Alam in Selangor (170), Pasir Gudang in Johor (169), Batu Muda in Kuala Lumpur (166), and Putrajaya (165).
The statement further listed Larkin in Johor (165), Seremban in Negeri Sembilan (164), Klang in Selangor (163), and Indera Mahkota in Kuantan, Pahang (163) as also falling within the unhealthy category.
In contrast, 33 other areas recorded IPU readings at the moderate level, while two areas maintained readings at the good level. The APIMS categorizes IPU readings between 0 and 50 as good, 51 to 100 as moderate, and 101 to 200 as unhealthy. This classification system provides a standardized metric for assessing air quality across the nation.
The widespread unhealthy readings highlight the immediate impact of haze on public health and daily activities in major urban centers and industrial zones. With 33 areas already in the unhealthy category by early morning, residents in these locations are advised to take necessary precautions. The data underscores the severity of the current haze episode, affecting key economic hubs in Selangor, Kuala Lumpur, Negeri Sembilan, Johor, and Pahang.
The situation remains a critical concern for policymakers and health authorities as they monitor the progression of air quality throughout the day.
