Practical tips to reduce indoor exposure to haze particles at home during a haze episode include:
- When the outdoor air quality appears to be worsening, close doors and windows.
- Stay indoors and reduce physical activities.
- Minimize activities that can produce indoor air pollutants in enclosed spaces, e.g. smoking.
What disease can haze cause?
What is the cause of haze?
Haze is caused when sunlight encounters tiny pollution particles in the air. Some light is absorbed by particles. Other light is scattered away before it reaches an observer. More pollutants mean more absorption and scattering of light, which reduce the clarity and color of what we see.
How can we prevent air pollution?
Ways to Reduce Air Pollution
- Riding a bike or walking instead of driving.
- Taking a bus or carpooling.
- Buying a car that has greater fuel efficiency.
- Turning off lights and appliances when they are not in use.
- Using energy efficient light bulbs and appliances.
- Buying fewer things that are manufactured using fossil fuels.
Why should we prevent air pollution?
Reducing pollutants in the air is important for human health and the environment. Poor air quality has harmful effects on human health, particularly the respiratory and cardiovascular systems. Pollutants can also damage plants and buildings, and smoke or haze can reduce visibility.
What are main causes of air pollution?
Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires. The solid and liquid particles suspended in our air are called aerosols.

What are the top 5 pollutants?
5 Major Outdoor Air Pollutants
- Ozone (O3)
- Nitrogen Oxides (NOx)
- Carbon Monoxide (CO)
- Sulfur Dioxide (SO2)
- Particulate Matter (PM10 and PM2.5)
What are the two main sources of pollution?
The main sources of pollution are household activities, factories, agriculture and transport. Once they have been released into the environment, the concentration of some pollutants is reduced by dispersion, dilution, deposition or degradation.
What are the natural sources of pollution?
Some of the natural sources of air pollution are organic compounds from plants, sea salt, suspended soils and dusts (e.g. from the Sahara). Other natural sources are released during catastrophes such as volcanic eruptions and forest fires.
What are two sources of water pollution?

What are pollutants and examples?
These are those which are emitted directly from the source and persist in the form in which they were added to the environment. Typical examples of pollutants included under this category are ash, smoke, fumes, dust, nitric oxide, sulphur dioxide, hydrocarbons etc.
What type of air pollution is most harmful?
Of the six pollutants, particle pollution and ground-level ozone are the most widespread health threats. EPA calls these six pollutants “criteria” air pollutants because it regulates them by developing limits that are based on human health and/or environmental criteria.
