Soil arsenic contamination in the Cape Region, B.C.S., Mexico.
We evaluated the content of arsenic in soils of an abandoned mining zone in the Cape Region, B.C.S. During June to August 1997, we were in the field sampling these soils. The concentration of arsenic was determined using the Chapman and Parket techniques. The results were statistically analyzed by ANOVA tests. Our results indicate that all the soils sampled in the region exceed the environmental limit (2 mg/K) established by Galvan and Corey (1987). According to the data found the more probable cause of this soil arsenic contamination is the rainy runoff.
