Abstract :

Background and Objective: Investigation of the amount of heavy metals, anions and cations in the air of SanandajMaterial and Methodology: The research method includes the measurement of suspended particles in the city. Then, atomic absorption spectrometry was used to determine the composition of particles and measure the desired metals and ions in the particles. In the third stage, the statistical method was performed and the results of field measurements in SPSS environment were analyzed. In the last stage, with the opinions of experts and determining the strengths and weaknesses, opportunities and threats, the relevant strategies were determined to investigate the causes of air pollution in Sanandaj and executive strategies.Findings: In this study, air quality in Sanandaj based on particles, has days with healthy air 20.83%, low pollution 69.14%, unhealthy days 7.43%, very unhealthy days equal to 1.38%, days Dangerous was 1.1% and very dangerous days were 1.65%. Days with dangerous and very dangerous weather were observed mainly in the first months of the year. Among metals, aluminum and iron have a very high volume, followed by copper, zinc, lead and arsenic. As for ions, they are sodium, nitrate, chlorine and sulfate, iron, magnesium and calcium, respectively.Discussion and Conclusion: Based on the results, changes in lead, mercury, manganese, zinc, aluminum and iron at the level of 5% are significant and there is a significant linear relationship between particles and the amounts of the above metals. Regarding ions, sodium, calcium, nitrate, sulfate and iron were significant at the level of 5%.
