Studying Air Quality Changes in Tabriz in Terms of PM10 Pollutant Density Using AQI Index and its Relation with Drop of Water Level in Uremia Lake during 2008-2011

Particles are main pollutants from view point of general health and environmental issue. The aim of this research was to review the monthly, seasonal and annual trend of PM10 and to determine air quality using AQI and its relation with drop of water level in Uremia Lake during 2008-2011 in order to present a knowledge base plan to manage particles.
This study is a cross-sectional typr. The data on PM10 were collected from Departement of Environment in Tabriz and Meteorological Organization of West Azerbaijan Provence. Then, the obtained data were analyzed considering air quality index using SPSS ver.21 software.
During the four years (2008-2011), changes in concentration of PM10 were meaningful (P=0.001). The concentrations in 2008, 2009, 2010, and 2011 were 86.13±70, 83.63±60.87, 87.40±42, and 92.69±73 microgram per cubic meter, respectively. Spring, winter, May and March had the highest amount of partcles as 103.18, 98.01, 88.81, 95.57 microgram per cubic meter, respectively.
Among the studied months, March and among the studied seasons, spring and winter possessed the worst air quality in terms of PM10. The reasons are intensity of particles entrance and environmental conditions during that period in one hand, and the worsen condition of Uremia Lake on the other hand. Therefore, several factors increase the amount of hazardous particles and salt particles effect. It can be condluded that there is a need for an integrated management to reduce these emissions
