What effects does chromium have on humans and the environment?

Answer 1

Human Effects:

Chromium VI (hexavalent chromium) is considered carcinogenic only to animals in certain circumstances at this point; chromium in general is currently not classified as a carcinogen as the OSHA and is fairly unregulated, but is considered toxic, level 3. While chromium III is essential for regular operation of human vascular and metabolic systems as well as combating Diabetes, too much chromium III may result in severe skin rash, or other more serious symptoms.

Chromium VI is the most dangerous form of chromium and may cause health problems including: allergic reactions, skin rash, nose irritations and nosebleed, ulsers, weakened immune system, genetic material alteration, kidney and liver damage, and may even go as far as death of the individual.

There is, however, no established limit for human consumption of chromium III. Individulals have been recorded as consuming 1000mg daily for elongated periods with no negative effects; but, as with all minerals our body needs, too much consumption may result in poisoning.

Environmental effects:

Chromium enters the environment through both natural processes and human activities. Increases in Chromium III are due to leather, textile, and steel manufacturing; Chromium VI enters the environment through some of the same channels such as leather and textile manufacturing, but also due to industrial applications such as electro painting and chemical manufacturing. Groundwater contamination may occur due to seepage from chromate mines or improper disposal of mining tools and supplies, and improper disposal of industrial manufacturing equipment.

Chromium can affect the air quality through coal manufacturing, which eventally can lead to water or soil contamination. Water contamination is fairly limited to surface water, and will not affect groundwater because chromium strongly attaches to soil and is generally contained within the silt layer surrounding or withing the groundwater reservoir. Water contaminated with chromium will not build up in fish when consumed, but will accumulate on the gills, thus, causing negative health effects for aquatic animals; chromium uptake results in increased mortality rates in fish due to contamination.
