Monthly Variation of Some Air Pollutants in Hilla City –Middle of Iraq

Abstract

This study is one of the recent approaches to deal with management of environmental pollution. It was carried out to analysize the pollution levels in the air, of hilla city. The study measured the pollutants concentrations of air such as PM10, NOX, CO, SO2 and O3. The results showed that TSP levels measured as (PM10) exceeded the standard level of pollution, the concentration level increased to reach a high concentration in babylon environment department station (693μg/m3),these concentrations exceeded the international standard levels, which indicates existance of pollution. CO concentrations in All stations went below the standard levels, its high concentrations masured in babylon university station air is (7.3 ppm) which is less than the standard levels. The results also revealed that SO2 concentration less than the standard (0.3ppm) because its average was (11.3ppb),alevel less than that of the International level .O3 average concentration was (54 ppb)and is also less than that of the standard.NOX average concentration was (45.4 ppb)and is also less than that of the standard. As a conclusion Hilla city air is principally polluted with PM10 due to effects dust storm espishaly at summer months, and transportation means and because of commercial and services activities . however the pollutants percentage with (NOX, CO, SO2 and O3. found in this study is less than that of the standard levels.The high percentage due to steady increasing of transportation means , traffic jam and bad fuel quality .
