Frequently Asked Questions
What is air pollution?
Air pollution consists of dust, chemicals and biological components.
Air monitoring studies have found that emissions from vehicles contribute 40-50 per cent of all air pollutants. Industrial sources are the next biggest contributor followed by construction activities and natural sources such as fires and volcanoes.
Is air pollution a problem in Vietnamese cities?
The World Health Organisation estimated in 2007 that 6,300 deaths per year were a result of outdoor air pollution.
Studies have identified that at heavy traffic areas in Vietnam the concentration of chemicals and dust particles regularly exceed the recommended air quality standards.
Reducing air pollution in urban and industrial areas has been identified as a priority area by the Strategic Orientation for Sustainable Development in Viet Nam (Viet Nam Agenda 21).
What chemicals are found in traffic pollution?
Every time we start an engine a mixture of petrol and air explodes and forms hundreds of chemicals. Some of the chemicals include carbon monoxide, nitrogen dioxide, sulphur dioxide and ozone.
Traffic fumes also consist of larger organic chemicals such as polycyclic aromatic hydrocarbons (PAHs). Some of these chemicals stay in the gas phase, while others attach to dust particles.
What dust particles are found in traffic pollution?
Man-made particles are produced from buses, cars, motorbikes and from coal-fired power stations, fireplaces and incinerators. Particles are classified into the larger particles (PM10) and fine particles (PM2.5)
What air pollutants can Karibon facewear block?
Karibon facewear contain Activated Carbon Cloth (ACC). ACC is proven anti-pollution technology capable of capturing large organic chemicals.
One group of chemicals that ACC can capture is polycyclic aromatic hydrocarbons (PAHs). A number of PAHs emitted from vehicles are classified as causing cancer in humans.
Independent laboratory testing found that Karibon facewear can block very small dust particles.
