Organic Pollution
INTRODUCTION
Definition of Pollution “the introduction by man into the environment of substances/energy liable to cause hazards to human health , harm to living resources and ecological systems , damage to structure or amenity or interference with legitimate uses of the environment”(Mason,2001) Definition of Pollutant “Chemical or physical in nature and can be measured more or less accurately in water”(Mason,2001)
Pollution of the aquatic environment • Introduction by man, directly or indirectly, of substances or energy which result in such deleterious effects as: -harm to living resources, -hazards to human health, -hindrance to aquatic activities including fishing, -impairment of water quality with respect to its use in agricultural , Industrial and often economic activities, and -reduction of amenities
Resource : World Health Organization(WHO)
What is Organic Pollution?
Organic pollution, usually related to discharge of sewage into coastal waters, affects the development of fouling directly and indirectly. Nutrient enrichment may cause eutrophication. The latter is the most harmful and causes depletion of oxygen in the water column (Aubert and Aubert, 1986).
What is Organic Pollutants?
Refer to chemical or physical discharged derived from living organism.(Lenntech B.V,2011)
Discharged of waste into water(consist of organic pollutants)
Excess of organic matter , depletion of oxygen
Lead to ORGANIC POLLUTION
MAJOR SOURCES OF ORGANIC POLLUTION
Musk Fragrances Rubber Factories Paper Pulp Mills
Industrial Effluent(Breweries , dairies and food processing plants)
Agricultural Activities
Sewage including raw or treated
• SEWAGE TREATMENT WORKS the design capacities of many sewage treatment works are below the population they have to serve. poor quality water discharged from a seawage treatment work into the rivers . cause chronic pollution of rivers. results in many parasitic infections and
