The present study aimed to determine the concentration of heavy metals like cadmium (Cd), chromium (Cr), manganese (Mn), nickel (Ni), and lead (Pb) in dust around the cement<br> factory.<br> Methods: A total of 22 dust samples were collected from areas around the cement factory in Isfahan province in spring and summer and transferred to laboratory for chemical digestion. Risk index (RI), integrated pollution index (IPI), mean of contamination degree (mCd), and contamination factor (Cfi)<br> were calculated to determine the contamination status.<br> Results: The concentration of heavy metals in the falling dust around the factory was expressed as Cd <ni a="" analysis="" and="" between="" br="" by="" cd="" concentration="" correlation="" cr="" cr.="" decreased.="" distance="" dust="" factory.="" falling="" from="" has="" high-risk="" in="" increasing="" is="" level="" middle="" mn="" negative="" of="" only="" pb="" pearson="" pollution="" potential="" relationship="" results="" seasons="" showed="" significant="" spring="" summer="" that="" the="" there="" two=""> Conclusion: According to the results, the deposited dust of study area is considered as a polluted dust and it is at higher risk of pollution with Cd and Cr.</ni></div> Cement factory, Dust, Environmental pollution, Heavy metals 129 137 http://ehemj.com/browse.php?a_code=A-10-407-3&slc_lang=en&sid=1 Firouzeh Yadegarnia Naeini fyadegarnia@yahoo.com 10031947532846005303 10031947532846005303 No Environmental Science Department, Natural Resources School, Yazd University, Yazd, Iran Hamidreza Azimzadeh hazimzadeh@yazd.ac.ir 10031947532846005304 10031947532846005304 Yes Corresponding Author: Environmental Science Department, Natural Resources School, Yazd University, Yazd, Iran Asghar Mosleh Arani amosleh@yazd.ac.ir 10031947532846005305 10031947532846005305 No Environmental Science Department, Natural Resources School, Yazd University, Yazd, Iran Ahad Sotoudeh asotoudeh@yazd.ac.ir 10031947532846005306 10031947532846005306 No Environmental Science Department, Natural Resources School, Yazd University, Yazd, Iran Bahman Kiani bnkiani@yazd.ac.ir 10031947532846005307 10031947532846005307 No Environmental Science Department, Natural Resources School, Yazd University, Yazd, Iran
