|
| Health care is an important human activity causing pollution to environment in many ways. It is ironical that the activities meant to care for human health are themselves causes of pollution and are detrimental to human health. The activities of health care, causing pollution to environment are: |
| |
|
| Where many pesticides are extensively used to kill insects like mosquitoes. Apart from killing mosquitoes, these chemicals cause large pollution to drinking water, soil as well as many food stuff. For e.g., Spraying DDT, BHC to control mosquito based human diseases is extensively taken up in our country as a part of public health care. |

|
| Bleaching powder is extensively used for sanitary applications as a disinfectant. But, bleaching powder can act as a source of chlorine contaminant in the sewage water systems of urban settlements. Such water may enter drinking water wells through the underground sources. |
| |
|
| Chlorine is commonly used to disinfect the drinking water. But, when its dosage is high it can act as source of water pollution. Excess chlorine in drinking water can be a cause for some digestive disorders. |
| |
|
| Hospitals use large amount of sensitive chemicals to control diseases. Further, they contain materials, utensils containing large amount of pathogens. When hospital wastes are not properly disposed off, they can cause many health hazards to healthy people - as pathogens and sensitive chemicals enter their body via water, food or air. |
| |
|
| Entry of excess flouride is dangerous to health of a person. It can cause flourosis. Many toothpastes used for dental care contain large quantity of fluorides. They may enter body during its use. |
