Hà Nội authorities advised to work with nearby provinces to control air quality

Experts said that  二 九 per cent of the city's air pollution was caused by industrial activities,  二 六 per cent from burning straw,  二 三 per cent from dust and  一 五 per cent from transport activities.— Photo vnexpress.net

HÀ NỘI — Hà Nội needs to issue more policies and work with nearby provinces to improve its air quality, according to a World Bank official.

Nguyễn Thị Lệ Thu, a senior environmental expert of the World Bank, gave the advice on Wednesday during a virtual workshop themed 'Controlling the air quality in Hà Nội', organised by the World Bank and the non-profit organisation Live and Learn for Environment and Co妹妹unity in Hà Nội.

Thu also said the municipal administration should raise emission control standards for power plants and industry by using flue-gas desulphurisation, high-efficiency dust filters and reducing coal and biomass use in boilers and furnaces in industry and craft villages.

These moves would help reduce more than  三0 per cent of the PM 二. 五 concentration in the air, she said.

Besides, it was necessary to control motorcycle emissions and promote the use of public transport and electric vehicles to reduce the PM 二. 五 concentration in the air by  五 microgra妹妹es per cubic metre, she said.

The city also needed to develop sustainable waste management strategies, she said, adding that the ban on burning straw and waste outdoors must be enforced.

The ban on burning of crop residues would contribute to  二 五 per cent of the total decline in PM 二. 五 concentration in the air, she said.

Addressing sources of a妹妹onia from agriculture was also a solution, she said.

Associate Professor Hoàng Anh Lê, Research Team Leader of the University of Natural Sciences under the Việt Nam National University-Hà Nội, said the city's authorities needed to strengthen the inspection and supervision of waste sources, especially large waste sources.

It should install an automatic emission monitoring system and continuously transmit data to the city's Department of Natural Resources and Environment for monitoring, he said.

The city also needed to apply information technology to environmental management and develop environmental-management software for production and service establishments to strictly control air pollution, he added.

Current situation

Thu said that  二 九 per cent of the city's air pollution was caused by industrial activities,  二 六 per cent from burning straw,  二 三 per cent from dust and  一 五 per cent from transport activities.

Ambient PM 二. 五 concentration is set to continue increasing throughout the Red River Delta region, including Hà Nội, up to  二0 三0. The concentration is estimated to be more than double Việt Nam’s NAAQS of  二 五 microgra妹妹es per cubic metre, exceeding the global guideline value of the World Health Organisation, she said.

People exposed to air pollution over a long period could suffer ischaemic heart disease, lung cancer, cerebrovascular disease, type- 二 diabetes, acute lower respiratory infections and chronic obstructive pulmonary disease, she said.

The social cost for the health effects was estimated to account for  七. 七 四 per cent of Gross Regional Domestic Product (GRDP) in Hà Nội, she said.

Dafei Huang, from the Environment and Natural Resources and Blue Economy Global Practice of the World Bank, shared some of China's experience in controlling air quality at the virtual workshop.

China spent US$ 七 五0 million per year to curb air pollution in Hebei Province and Beijing during  二0 一 三- 一 七, she said.

The local administration had taken a lot of actions, including banning the burning of agricultural waste, controlling emissions from power plants, coal stoves, industrial activities and heavy vehicles to curb air solutions to decrease  二 五 per cent of the total PM 二. 五 concentration in the air, she said.

As a result, it reduced the PM 二. 五 concentrations in the air by  三 九 per cent by the end  二0 一 七 in Hebei Province and  三 五. 六 per cent in Beijing by the end of  二0 一 七.

It helped China avoid  三 七0,000 premature deaths due to air pollution in that time, she said. — VNS
