What does an API reading of 183 signify for public health?

Question

Accepted Answer

An API Reading of 183 Indicates Unhealthy Air Quality with Potential Health Risks

An Air Pollutant Index (API) reading of 183 signifies that air quality is at an unhealthy level. This means that the general public may begin to experience health effects, and sensitive groups could experience more serious effects. While the specific API range for unhealthy air is between 101 and 200, a reading of 183 falls within the upper end of this category, suggesting a more pronounced impact on air quality.
Unhealthy Air Quality Levels Nationwide

As of 9am on the day of the report, 11 areas across Malaysia were experiencing unhealthy air quality. Sarawak was the most severely affected region, with Samarahan recording the highest API at 183. Other locations in Sarawak that registered unhealthy readings included Serian (182), Kuching (176), Sarikei and Sri Aman (158), and Mukah and Sibu (152). In Peninsular Malaysia, four areas were affected: Johan Setia (154) and Shah Alam (101) in Selangor, Kuala Lumpur (131), and Putrajaya (104).
API Classification Standards

The API is a system used to report daily air quality in Malaysia. Readings are categorised to inform the public about the level of pollution. An API reading from 0 to 50 is considered good, while 51 to 100 is moderate. Readings between 101 and 200 are classified as unhealthy, 201 to 300 as very unhealthy, and anything above 300 is deemed hazardous. The data is updated hourly from 68 monitoring stations nationwide.
General Health Implications of Unhealthy Air

When air quality is at an unhealthy level, it generally indicates the presence of pollutants that can cause adverse health effects. Exposure to such air can lead to respiratory symptoms like coughing, wheezing, and shortness of breath. Individuals with pre-existing respiratory conditions, such as asthma or bronchitis, as well as the elderly and children, are considered more vulnerable and may experience exacerbated symptoms or other health complications. Prolonged exposure to unhealthy air can also contribute to cardiovascular issues.
