Transcript of water Pollution in africa

Water Pollution In Africa By: Ashley Dawkins What is water pollution? Water polltion is the contamination of a body of water. What is causing water pollution in africa? Surface water pollution is one of the serious
environmental problems in rural areas of South Africa due to
discharge of household waste into the streams, turning them into
open sewers. Most water pollution is caused by man and its construction activities in this area of africa.
The water quality in the rural areas of south africa
was found to have deterioted significantly after water runoff
from farms and household wastes. The result shows, fertilizer runoff contributes to 50% of the population while pesticides and sediment contributes up to 10% respectively in the streams , while household waste contributes up to 30%.

What are some water born illnesses caused by water pollution? The diseases fall into three major catagories: bacterial (caused by bacteria in water)
Viral(caused by viruses in the water)
and parasitic(caused by parasites in the water. Dysentery is an inflammation of the intestine characterized by the frequent passage of feces with blood and mucus. Like cholera, dysentery is spread by fecal contamination of food and water, usually in impoverished areas with poor sanitation. Epidemics are commonthat started in 1968, rcaused more than 500,000 cases and more than 20,000 deaths. Since 1991, dysentery epidemics have occurred in eight countries in southern Africa (Angola, Burundi, Malawi, Mozambique, Rwanda, Tanzania, Zaire, and Zambia).
What is Dysentary? How many children die from water born illnesses? About 29,000 children under the age of five – 21 each minute – die every day, mainly from diseases caused by drinking polluted water.

More than 70 per cent of almost 11 million child deaths every year are attributable to six causes: diarrhoea, malaria, neonatal infectition and other diseases.

These deaths occur mainly in the developing world. An Ethiopian child is 30 times more likely to die by his or her fifth birthday than a child in Western Europe. Among deaths in children, South-central Asia has the highest number of neonatal deaths, while sub-Saharan Africa has the highest rates. Two-thirds of deaths occur in just 10 countries.
. UNICEF helps develop systems to control water-borne diseases like Guinea worm and cholera that undermine child survival and development, reduce productivity and raise health-care costs. Struggles to find water and hygiene resources also primarily increase burdens on girls and women.

Working closely with governments, UNICEF also helps strengthen policies and budgets and support technical capacities in programmes for hygiene promotion, sanitation, cost-effective water supply options and water quality, particularly for poor rural and urban families. These activities also aim toward fulfilling Millennium Goals 4 and 7.

UNICEF also helps develop partnerships that pool competencies and resources, particularly in its role as advocate, facilitator and coordinator in emergencies Increasing access to improved water and sanitation How can we help? We can help by donating to organizations lthat send money over to africa to build wells Organizations that fund africa's clean water program African Well Fund ANEW Blood:Water Mission The Water Project charity:water Water Pollution in Africa
By:Ashley Dawkins Top 10 countries with the highest death rates in africa due to water pollution (deaths per 1,000 population0 1) Swaziland - 30.70 2) Angola- 24.44 3) lesotha - 22.33 4) Sierra Leone- 22.26 5) Liberia- 21.45 6) Zambia - 21.35 7) Mozambique- 20.29 8) Niger- 20.26 9) Afghanistan -19.56 10) Dijibouti -1916 Waterborn illnesses Bacterial:
acute dehydrating
typhoid fever
chronic diarrhea
Viruses: Hepatitis A
Polio,fever, diarrhea,muscle paralysis
parasitic- helminths protozoa ectoparsites Epidemic dysentery is a major problem among refugee populations, where overcrowding and poor sanitation facilitate transmission. Epidemics are characterized by severe disease, high death rates, person-to-person spread, and multiple antibiotic resistance. Worldwide, approximately 140 million people develop dysentery each year, and about 600,000 die. Most of these deaths occur in developing countries among children under age five. In the United States, only about 25,000 to 30,000 cases occur each year. Dysentary and its effects
