Effects of Population Weighting on PM10 Concentration Estimation
Table 2
Four exposure levels established with reference to the new Malaysia ambient AGQ and IT guideline for annual mean PM10 concentrations.
| | Exposure level | PM10 ranges (µg/m³) | Malaysia interim target | Target year to achieve |
| | 1 | PWEL ≤40 | Air quality standard | 2020 | | 2 | 40 <PWEL ≤45 | Interim Target-2 (IT-2) | 2018 | | 3 | 45 <PWEL ≤50 | Interim Target-1 (IT-1) | 2015 | | 4 | PWEL >50 | — | — |
