pollution

I know about air pollution. Pollution can be from cleaning products, dust, paint, insect spray, cigarette smoke or steam from cooking.  Some pollutants such as smoke and insect sprays can cause breathing problems such as asthma.

In my house we also use cleaning products.  We have dust,cigarette smoke and stream from cooking.  As for me, I cook food like salads, open windows for 2-3 hours, and clean bedding and items used by my pets regularly.

Your English is excellent. Most of my corrections were punctuation, specifically, to always leave one space following a comma, and two spaces following a period at the end of a sentence (a good habit to develop for American English if you anticipate writing academic papers or formal correspondence.)  Your subject was interesting. Thank you for the opportunity of reading this.
