Characterization, ratio analysis, and carcinogenic risk assessment of polycyclic aromatic hydrocarbon compounds bounded PM10 in a southwest of Iran

Background/objectivesA group of environmental carcinogens are polycyclic aromatic hydrocarbons (PAHs) that formed during the incomplete combustion organic materials. The aims this study was evaluated Characterization, ratio analysis, and carcinogenic risk assessment hydrocarbon compounds bounded PM10 in a southwest Iran.MethodsIn descriptive-cross-sectional study, conducted every 4 seasons. In each region, 20 air samples total 40 were collected by OMNI device two regions.ResultsBased on result cold season average concentration PAHs higher than hot season. Anthracene fluorine with 4.70 4.25 ng/m3 naphthalene anthracene 4.07 3.48 warm highest mean among other compounds. results diagnostic ratios also showed main source Shushtar city is fossil fuel use gasoline cars.ConclusionAccording to amount season, effects temperature it can aggravate these pollutants. Considering mainly produced as fuels transportation, necessary pay more attention pollutants control sources their emission. It create culture society order increase public transportation.
