Ha Noi suffers air pollution

Update: September, 27/2015 - 12:00

Three cities in Asia have something in common.

Ha Noi, Karachi and Delhi all have air that is far too polluted.

The pollution is caused by vehicles that let out gases.

However, there are also other things that add to the pollution, such as factories and charcoal burning.

HA NOI (VNS) — Seventy per cent of air pollution in Ha Noi is created by the endless streams of traffic, the Centre for Environmental Monitoring has reported.

The content of PM10 (particles less than 10 micrometers in diameter) caused by traffic is four times higher than the alarm rate set by the World Health Organization (WHO), according to Jacques Moussafir, a French environmentalist.

Ha Noi pollution level was equivalent to that of Delhi and Karachi, two of the 10 most polluted cities in the world, Thoi bao Kinh doanh (Business Times) quoted Moussafir as saying.

Research conducted by the World Bank reveals that Ha Noi is among the most polluted cities in Asia.

"If no solutions are sought, the content of micro particles in Ha Noi will reach 200mg/ m³, 10 times higher than WHO's warning level," he said. This is two-and-a-half times the present rate.

Statistics from ARIA Technologies, a French company specialising in environmental research, shows that each year the number of vehicles in Ha Noi rises by 12-15 per cent. Vehicles discharge such toxic substances as sulphur dioxide and nitrogen oxide.

"Frequent and prolonged traffic congestion is another contributor to the increasing air pollution level," said Professor Le Huy Ba, head of the Institute for Science, Technology and Environment Management under HCM City University of Industry.

The emissions, which are released at low levels, are concentrated in densely-populated areas, he said.

Pollutants also come from industrial zones, craft villages, constructions sites, charcoal production and garbage from residential areas.

Up to 90 per cent of air samples checked in Ha Noi do not meet safety criteria and increase negative impacts on human health, Thoi Bao Kinh Doanh reported, referring to the World Bank's research.

Environment experts state that an increased use of public transport instead of personal vehicles would help solve the crisis. However, the limited number and low quality of buses in Ha Noi cannot meet present demands.

Hoang Duong Tung, deputy head of the Viet Nam Environment Administration, proposed setting up at least 10 more environment monitoring stations as a primary solution.

At present, only two stations have been set up in the city to monitor air quality.

The second important solution should be limiting charcoal burning for cooking and encouraging the use of solar energy, Tung said.

He added that it would also be necessary to move polluting industries out of the inner city and require them to install systems to deal with emissions.

The municipal People's Committee plans to move polluting factories out of the city's urban and residential areas by 2015, but progress remains slow.

People with heart or lung diseases, older adults and children are most likely to be affected by particle pollution exposure. However, even if you are healthy, you may feel temporary symptoms if you are exposed to high levels of particle pollution.

Numerous scientific studies connect particle pollution exposure to a variety of health issues, including: Particle pollution can cause irritation of the eyes, nose and throat, coughing, chest tightness and shortness of breath, reduced lung function, irregular heartbeat, asthma and heart attacks - and premature death in people with heart or lung disease. — VNS

GLOSSARY

The content of PM10 (particles less than 10 micrometers in diameter) caused by traffic is four times higher than the alarm rate set by the World Health Organization (WHO), according to Jacques Moussafir, a French environmentalist.

The content of pollution is everything that the pollution has in it.

One micrometer is one millionth of a meter.

Ha Noi pollution level was equivalent to that of Delhi and Karachi, two of the 10 most polluted cities in the world, Thoi bao Kinh doanh (Business Times) quoted Moussafir as saying.

Equivalent means equal in value.

By quoting someone you tell people their exact words.

If no solutions are sought, the content of micro particles in Ha Noi will reach 200mg/ m³, 10 times higher than WHO's warning level," he said. This is two-and-a-half times the present rate.

Solutions are answers to problems.

When solutions are sought, someone looks for answers.

WHO stands for World Health Organisation. It is part of the United Nations.

Statistics from ARIA Technologies, a French company specialising in environmental research, shows that each year the number of vehicles in Ha Noi rises by 12-15 per cent.

Statistics are figures that are collected during a study of something.

Vehicles discharge such toxic substances as sulphur dioxide and nitrogen oxide.

When vehicles discharge things, they send them out their exhaust pipes.

Toxic substances are poisonous mixtures.

Sulphur dioxide and nitrogen oxide are both gases.

"Frequent and prolonged traffic congestion is another contributor to the increasing air pollution level," said Professor Le Huy Ba, head of the Institute for Science, Technology and Environment Management under HCM City University of Industry.

Something that is prolonged carries on and on and on.

Traffic congestion happens when there are lots of vehicles on a road that they are only able to move slowly, if at all.

The emissions, which are released at low levels, are concentrated in densely-populated areas, he said.

Emissions are the same as discharges.

If emissions are concentrated in densely-populated areas, most of them happen in places where there are many people living close to one another.

Pollutants also come from industrial zones, craft villages, constructions sites, charcoal production and garbage from residential areas.

Pollutants are things that make up pollution. They are the contents of pollution.

A residential area is an area of a city where people's homes are situated.

Up to 90 per cent of air samples checked in Ha Noi do not meet safety criteria and increase negative impacts on human health, Thoi Bao Kinh Doanh reported, referring to the World Bank's research.

A  sample of air in Ha Noi is a small amount of air from the city that gives you an idea of what all the air in Ha Noi is like.

Safety criteria are standards by which safety is measured.

Environment experts state that an increased use of public transport instead of personal vehicles would help solve the crisis.

Public transport is transport that is available for everyone to use. Bus services, trains, taxis and scheduled flights are examples of public transport.

Hoang Duong Tung, deputy head of the Viet Nam Environment Administration, proposed setting up at least 10 more environment monitoring stations as a primary solution.

To propose setting up monitoring stations means to put forward the idea as being a good thing to do.

Environmental monitoring stations are put in place at different locations to keep a watch and measure things to do with the environment, such as air pollution, winds and so on.

A primary solution is the best answer to a problem and the first that should be used.

The second important solution should be limiting charcoal burning for cooking and encouraging the use of solar energy, Tung said.

Solar energy means energy from the Sun.

However, even if you are healthy, you may feel temporary symptoms if you are exposed to high levels of particle pollution.

Symptoms are things you see and feel that indicate that you may have a certain sickness.

Temporary symptoms are symptoms that do not last forever.
