How are chromium-contaminated soils a health hazards. What is the importance of early investigation and the uncertainties that include dose response, hazards or probability and are there any long term effects to humans?© BrainMass Inc. brainmass.com October 16, 2018, 6:51 pm ad1c9bdddf
The main source of chromium-contaminated soils electroplating, textile manufacturing, leather tanning, pigment manufacturing, wood preserving, and chromium waste disposal (U.S. EPA, 1997). There are many compositions of chromium, however, the most significant soil contamination problem is hexavalent chromium [Cr(VI)] which is acutely toxic, mutagenic, and carcinogenic in the environment.
Thresholds exist for ...
Describe how chromium-contaminated soils are a health hazards. Define dose response, hazards, probability and long term effects to humans.
Environmental Science - what is meant by the Environmental Revolution?
1. Revolutionary changes in human culture have greatly changed the relationship between humans and the environment. How have the Neolithic and Industrial Revolution impacted the natural environment, and what is meant by the Environmental Revolution?
2. The recycling of elements is another vital functional process occurring in all ecosystems. Describe the biogeochemical cycles for carbon, phosphorous, and nitrogen. How have humans impacted these three cycles?
