摘要: The environmental damage caused by industrial activities in Cromatos de Mexico, (Tultitlan, Mexico) has been evaluated terms of heavy metal concentrations topsoils the surrounding area. lead, copper and zinc demonstrate a significant enrichment with respect to unpolluted levels. Their maximum factors are 37.7, 21.1 9.6 mg kg−1, respectively; such increase is related traffic emissions. Nickel show no difference analyzed samples. Total chromium decrease distance from facilities, ranging 15 1,837 kg−1. (total), background values reach up 40.8 In spite this pronounced increase, only three samples (VI) over 0.5 kg−1 (instrumental detection limit) do not exceed recommended Mexican official norm. current results that present studied area does represent serious health risks zone, nevertheless, it necessary consider oxidation (III) determinate changes redox and/or pH conditions which would imply impacts upon its toxic risk. This study suggests waste material generated during Mexico represents relevant pollution source for even 30 years after closure facilities.
