Pollutant effects

Hydrocarbons (fuels and solvents)

Damage fish gills so they can't breathe, poison animals and burn plants. They contain cancer-causing agents that build up in fish and shellfish. Petrol and its vapours are a major fire and explosion hazard, especially in confined spaces such as stormwater pipes. The heavier components of these hydrocarbons accumulate in the bed sediments of a water body.

Sewer Related Wastewater

Nutrients such as phosphates, nitrates and those contained in domestic sewage promote the uncontrolled growth of plant and bacteria populations within the aquatic environment. Waterways can be choked with weeds or depleted of oxygen by unnaturally high populations of micro-organisms.

Concrete Wastewater

Concrete wastewater raises the pH level of waterways it enters. Levels of pH outside the natural range damage sensitive tissues such as eyes, gills and skin, make it impossible for juvenile creatures to survive and burn or kill mature fish, plants and insects.

Paint, Ink & Dye

Can all be poisonous to creatures that come in contact with them. They prevent light from entering the water, making it difficult for plants to get the energy they need to live and for animals to find food.
