Nine stations equipped with an LVS were selected for TSP sampling from air simultaneously. Sample analysis was performed in the laboratory using gravimetric methods and data depicted by ArcGIS to recognize spatial distribution. &nbsp;<span dir="RTL"></span><br> <strong>Results:</strong> Changes in TSP concentrations were within the range of 30.17-2,692.82 &mu;g/m³ and exceeded the EPA/WHO guidelines in more than 98% of the cases. Spring and winter showed the highest levels. The main influential factors in the TSP concentration were industrial activities, vicinity to the depot site and main streets, the speed of passing vehicles, and the dominant wind direction.<br> <strong>Conclusion:</strong> Despite recent attempts to control TSP, the concentrations remain high and alarming. Therefore, special attention must be paid to the health issues affecting staff and residential groups and implementation of more effective control mechanisms.</span></span> &nbsp;&nbsp;&nbsp;<span dir="RTL"></span></div> Air Pollution, Industrial Pollution, Total Suspended Particles (TSP),Mapping, 22 29 http://jhehp.zums.ac.ir/browse.php?a_code=A-10-141-1&slc_lang=en&sid=1 Azadeh Tavakoli atavakoli@znu.ac.ir 100319475328460011141 100319475328460011141 Yes Department of Environmental Sciences, University of Zanjan, Zanjan, Iran.
