本文讨论了墨西哥中部莱昂谷的一家铬酸盐工厂和制革厂的生产对环境和健康的影响。对水、土壤和人尿中的铬进行取样和分析。地下水已被污染的面积约5公里（2）的固体工厂废物的浸出，这导致浓度高达50毫克/升的六价铬。羽流的形状和延伸似乎是由当时的油井开采制度控制。在工厂周围的土壤中检测到总铬，这是由于铬酸盐工艺产生的粉尘的空中运输和沉积以及制革厂污染水的灌溉。分析空气和水中的铬对不同程度接触的人群的影响表明，没有观察到高度有害的健康影响。
The effects on the environment and health of the operation of a chromate compounds factory and tanneries in the Leon valley in central Mexico are discussed. Sampling and analysis of chromium were performed in water, soil, and human urine. Groundwater has been polluted in an area of about 5 km(2) by the leaching of a solid factory waste, which results in concentrations up to 50 mg/l of hexavalent chromium. The plume shape and extension appear to be controlled by the prevailing well extraction regime. Total chromium was detected in the soil around the factory as a result of both aerial transport and deposition of dust produced in the chromate process and irrigation with tannery-contaminated water. Analysis of the impact of chromium in air and water on populations with various degrees of exposure revealed that highly harmful health effects were not observed.
