The knowledge of women, youths (18 - 20years old), university educated people (PhD), westerns and northern, and those who had got their information from radio / TV is more than others. The knowledge of people about the environmental pollution and their health effects with education level and source of information had a significant difference. After elimination the effect of variables that probably interfere with knowledge of people, logistic regression was done. In this case, there was a correlation between education level and information sources. More than 80% of people got their information from radio and TV.
