PM2.5 pollution still problematic across Viet Nam

PM2. 5 pollution still problematic across Viet Nam xxGNb
HÀ NỘI — Though the average PM2. 5 concentration improved slightly in 2020, all provinces and cities in Việt Nam still had much higher levels than the WHO’s recommendation, according to data revealed at a workshop held virtually on Tuesday. In 2020, the areas with high PM2. 5 concentration were mainly in the Red River Delta, the north-central region, and the southeast region, according to the findings from a report on the state of PM2. 5 in Việt Nam during the 2019-20 period. The report is based on multisource data and is conducted by the University of Engineering and Technology under the Vietnam National University in Hà Nội ̣(VNU-UET) and Live & Learn for Environment and Community. “The improved air pollution nationwide in 2020 was due in part to the social distancing due to the COVID-19 pandemic, ” said Associate Professor and Doctor Nguyễn Thị Nhật Thanh, from VNU-UET, an author of the report. Data in 2018 showed that major sources of PM2. 5 pollution in Việt Nam came from burning agricultural by-products (40 percent), cooking (17 percent), transport (13 percent), forest fires (12. 7 percent), and industrial activities (11 percent), and thermal power (3. 3 percent). In Hà Nội, 48. 3 percent of the PM2. 5 pollution was caused by industrial and craft village activities, 21. 3 percent from transport, and 20. 2 from burning agricultural by-products. In HCM City, 58. 2 percent of the pollution came from transport, 22. 8 percent from industrial activities, and 12. 8 percent from cooking. In 2020, Việt Nam had 10 out of 63 provinces and cities with higher PM2. 5 concentration levels than the nationally mandated threshold. These 10 localities are all in the north including Hà Nội with PM2. 5 level at 29 µg/m³ and Bắc Ninh Province at 33 µg/m³, much higher than the national allowed threshold of 25 μg/m³ and WHO's the guideline of 5 μg/m³. In 2019, the number was 13 localities, of which 11 were in the north and the rest were in the south. Data crucial for air quality control In the past few years, the state of PM2. 5 in Việt Nam has been studied and published in reports and scientific journals by researchers from government agencies, universities, institutes, and social organizations. However, the data used in these reports are often limited in terms of timespan or geographical coverage and have not utilized open-source data, including data from satellites, and citizen science monitoring networks. “Our report provides comprehensive information on the spatial and temporal distributions of air pollution due to PM2. 5 in Việt Nam. The findings from the report will be a supplemental source of data, helping provinces and cities to develop air quality management plans, ” said Thanh. Hoàng Dương Tùng from Vietnam Clean Air Partnership said: “It is crucial to promote research to identify the sources of PM2. 5 pollution and other air pollutants, especially in provinces and cities heavily polluted by PM2. 5. ” “The findings from these reports will help authorities to determine priority plans to manage the air quality, ” he said. The workshop “State of PM2. 5 in Việt Nam during 2019-2020 based on multisource data and application of satellite technology in air pollution monitoring and research” was held by Live & Learn for Environment and Community (Live&Learn/USAID), University of Engineering and Technology under the Việt Nam National University in Hà Nội, Việt Nam Clean Air Partnership and Tia Sáng Magazine. Việt Nam is ranked 115th in air quality that measured household solid fuel use and PM2. 5 average exposure in the biennial Environmental Performance Index compiled by scientists at American universities Yale and Columbia. According to the World Health Organization, air pollution is one of the greatest environmental risks to health. By reducing air pollution levels, countries can reduce the burden of disease from stroke, heart disease, lung cancer, and both chronic and acute respiratory diseases, including asthma. The organization estimated that in Việt Nam, around 60, 000 deaths each year are air pollution-related. — VNS
