Finding F-0193

“The result shows that the 12 h mean average concentration ± standard deviation of PM2.5 S1 (BB) (41.00 ± 58.82 μg m−3) and at S2 (BB) (65.33 ± 175.10 μg m−3) exceeded the limit suggested by MAAQS-2020 and USEPA, which is 35 μg m−3.”

Structure

Source: Biomass fuel
Factor: Particulate matter (PM₂.₅ and PM₁₀)
Setting: rice field (ambient), MY
Study design: field measurement study of PM2.5 at two sites during local open rice straw burning after harvest in Malaysia, with trace element, morphological and bacterial characterisation of the particles (class 4)
Effect: mean 65.33
Averaging time: 12 h mean
Caveat: open burning of rice straw is filed under biomass-fuel, the nearest source slug
