4. Photo by Sudhanshu Malhotra Do you know it affects us all?

5. Natural Chemical Anthropogenic Microbial WATER POLLUTION

7. Fluorosis ©Ruhani Kaur/UNICEF India http://www.fannz.org.nz 20 states in India have groundwater that is rich in fluoride Dental Fluorosis Skeletal Fluorosis Excess fluoride in the body (above 1.5 – 2 ppm) Natural pollution

13. Chemical contamination and its impacts Anthropogenic pollution Lead : Kidney, nerve and brain damage; anaemia – leads to death. Children most susceptible Cadmium : Kidney damage, genetic mutations Mercury : Damage to brain and central nervous system

14. Chemical contamination and its impacts Anthropogenic pollution Synthetic Organic Chemicals These compounds bio-accumulate in our bodies and are dangerous to health and life. Cause cancers, damage to the nervous system, reproductive system, endocrinal system Dyes Plastics Pesticides

15. Bio-magnification Accumulation of these compounds increases as we go up the food chain. Organisms higher in the food chain are exposed to contamination from different sources.

17. Minamata disease Strange things started to happen – cats had convulsions and died, crows fell from the sky, dead fish floated.. Young children had convulsions and difficulty in walking and speaking People died Investigation showed organic mercury poisoning affecting the nervous system First discovered in 1956 Lawsuits and claims continue till today Anthropogenic pollution

18. Health impacts of Microbial contamination of water Water-borne Diseases Water-washed Diseases Water-based Diseases Water-related vector borne Diseases Anthropogenic pollution

21. The Faecal-Oral Route of Disease Transmission Food Excreta Hands Water Flies Mouth

22. Diarrhoeal disease Children in developing countries most affected Responsible for the deaths of 7,00,000 million people every year (WHO, 2004) Over 7,00,000 deaths in India in 1999 (works out to abt 1600 per day) (World Bank, 1999)

24. Water washed diseases Scabies Trachoma Not enough water to keep clean
