Survey of air pollutants of the air surrounding Barez Industrial Complex in Kerman

Consequences of air pollution on the health effects، including the formation and aggravation of respiratory، neurological and cardiovascular disease، caused air quality monitoring and control as something inevitable in most urban & industrial areas issue that should be raised at national level. Industries are among important pollutant factors of the environment that contaminate their surrounding at the first step. Since air pollution monitoring has not been done in the air surrounding Barez Industrial Complex، therefore a research study is required to review air quality. This study is of descriptive–cross sectional type and was performed from June to November of 2011. Monitoring of conventional pollutants (NO2،SO2،O3،PM10،CO) HC، and precipitated particulates was performed through interpolation between the concentration of pollutants inside the plant and its comparison with Air Quality Index (AQI). Air plant area was measured and evaluated in four symmetric directions and two different radii، and eight stations and three times a month for six months. 152 & 48 samples were taken from each pollutant and precipitated particles respectively. Air Quality was determined based on Iranian standard. the results of the tests showed that mean daily maximum concentration particulate matter (PM10) was 127/65 µgr/m3، nitrogen dioxide (NO2) equal 38/14 ppb، sulfur dioxide (SO2) equal 88/4 ppb،carbon monoxide (CO) equal 1/38 ppm، ozone (O3) equal 49/19 ppb. the carbohydrates equal 0/095 ppm and the monthly overage concentration of settleable particles13/35 gr/m2. mon. In all cases have been below the limit allow. Also the air quality index of all samples was within Iran’s air quality standards، WHO guidelines US-E and PA standards. Air quality is of suitable status in terms of maintaining health of workers & visitors. considering that the concentration of suspended particles (PM10) and the SO2 emissions are higher than other pollutants necessary measures should now be taken to prevent their concentration increase which may exceed the standards in future if proceed with present trend.
