Presentation transcript:

Water Pollution contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and groundwater occurs when pollutants are directly or indirectly discharged into water bodies w/o adequate treatment to remove harmful compounds. Toxic substances are Dissolved Suspended Deposited

Methods of Water Pollution Industrial Waste Discharge City Sewage Discharge Methods of Water Pollution Agricultural Spills Dumping Acid Rain

Types of Contaminants Sediments Bacteria, Viruses, Parasites Metals (Lead, Cadmium, Arsenic) Sediments Bacteria, Viruses, Parasites Pesticides/Fertilizers Nitrates, Phosphates, Ammonia Types of Contaminants Radioactive Material Pharmaceuticals Sewage

Types of Pollution

Eutrophication

No oxygen to support Life 5. Ecosystem DEATH No oxygen to support Life 1. Extra Nutrients from fertilizers run-off into rivers and lakes 3. Algal Blooms (Depletes Oxygen & Blocks Sunlight) Plants Die 2. Plant growth increases (Algae, Duckweed, & other aquatic plants 4. Decomposition Bacteria break down dead plants causing MORE oxygen depletion

Concentration of Toxin INCREASES as it moves up the food web What Happens When Pollutants Get Into the Food Web?? Concentration of Toxin INCREASES as it moves up the food web Biomagnification

Bioaccumulation Accumulation of a toxin/contaminant in the FAT tissue of an organism.
