If you cook with gas, switch to electric stove.

good ventilation system can reduce indoor air pollution.

This is the overall information about my question. I hope this information will help who is following this this post.

Ø  Subsidization of cleaner fuel technologies, like kerosene and LPG/gas rather than traditional biomass fuels.

Ø  Use of solar thermal cookers and solar hot water heaters.

Ø  Processing biomass fuel to make them cleaner.

Ø  Modifying user behavior plays a role in reducing exposure to indoor smoke.

Ø  Drying fuel wood before use improves combustion and lowers smoke production while using lids on pots, reduces cooking time.

Ø  Improve household design/using modern or improve stoves

The amount of heavy metal in home environment may still be able to reduce by restricting the use of windows and by practising better housekeeping such as frequent wet mopping and vacuuming.

 pollution can be reduced by using electric devices for cooking instead of gas.
