2. Central Nervous System
3. Gastro-intestinal problem
4. Arthritis
5.

Answer 1

Correct Answer - Option 2 : Central Nervous System

• Chromium is an odorless and tasteless metallic element. Chromium is found naturally in rocks, plants, soil and volcanic dust, and animals.
• The most common forms of chromium that occur in natural waters in the environment are:
• Trivalent chromium (chromium-3)
• Hexavalent chromium (chromium-6)
• Chromium-3 is an essential human dietary element. It is found in many vegetables, fruits, meats, grains, and yeast. Chromium-6 occurs naturally in the environment from the erosion of natural chromium deposits. It can also be produced by industrial processes. There are demonstrated instances of chromium being released to the environment by leakage, poor storage, or inadequate industrial waste disposal practices.
• Chromium as a contaminant in drinking water in excess of permissible levels, causes Central Nervous System.
