Analysis were developed using EPA methods:SW 846: 3050B/6010B for arsenic and lead (FLAAS); and EPA SW846: 7471A for total mercury (CVAAS). Compared to a recommendedconcentration in soil of 20 mg/kg for arsenic and mercury and 100mg/kg for lead (PROFEPA Interim Criteria of 2001), the concentrationof heavy metals was found to be up to 8 times higher for the metalsanalyzed. With this information a dispersion model was run inorder to get iso-concentration curves and to establish risk zones.From the data, two hot spots were identified (towns of La Zacatecanaand Osiris) where mercury, lead and arsenic total concentration ishigher enough to justify future speciation studies to evaluate the riskto the population within the area. 2006 artículo científico 1870-249X https://www.redalyc.org/articulo.oa?id=47550202 en http://www.redalyc.org/revista.oa?id=475 Journal of the Mexican Chemical Society application/pdf Sociedad Química de México Journal of the Mexican Chemical Society (México) Num.2 Vol.50 |
