Cong Liu, from the Key Laboratory of Public Health Safety at Fudan University in Shanghai, and colleagues examined the correlations for PM10 and PM2
.5 with daily all-cause, cardiovascular, and respiratory mortality.
However, the concentrations of PM2
.5 noted during the day and evening time were recorded slightly lower than NEQS whereas the overall ambient air quality of the federal capital was healthier today.
They chose Burgos for the study since the research wanted to look into the presence of PM2
.5 in areas where there is little economic activity, Cayetano told the Inquirer on Tuesday.
The particulate matter of 2.5 microns (PM2
.5) ratio was witnessed to 29.75mg/mA3 against the NEQS of 35 mg/mA3, the report said.
Within cities, emissions of PM2
.5 from road vehicles are an important source.
In 2015, more than half of the Indian population, about 670 million citizens, were exposed to PM2
.5 concentrations that did not comply with India's NAAQS for PM2
.5 (40 mg/m3).
Liaw Yung- po, a professor at the university, said that although the city of Taichung did not exceed standards for PM2
.5 and carcinogens, there are seven districts which were found to have concentrations of eight carcinogens so high, that just inhaling the air would put residents at a higher risk.
The average density of PM2
.5 in the city rose to 120 micrograms per cubic meter last month, up 15 percent compared with the same period last year, Burenduuren Uyanga told Xinhua.
.5 is a particulate matter (ambient airborne particles), which measures up to 2.
IQAir's website claimed Phnom Penh's PM2
.5 reading was at 152, while the ministry's monitors registered a PM2
.5 reading of around 25 on February 25.
Each increase by 10 ug/m3 in levels of PM2
.5 is assumed to increase death rates by 6%.
