6. Silver is used in photography, and so some silver could be released into water from photographic processing. Then, some silver could be released to air when entering environments through natural processes. This could prove harmful because when humans get lower- levels of exposure to this, the silver could be deposited in the skin and other parts of the body, but not really harmful. If we get high-level exposures of silver in the air, it could cause breathing problems, lung irritation, throat irritation, stomach pain and agyria, a disease that causes the skin to turn blue-grey and other organs.. Also, when silver comes in contact with the skin, it may cause mild allergic reactions like rash, swelling and inflammation in some people.
