Industrial Pollution
Introduction | Identification | Impacts | Causes | Actions | More Info

Discharges of petroleum products, heavy metals, pesticides, fertilizers, and heated wastewater are harmful to marine-life and can be particularly detrimental to coral reef ecosystems. These pollutants are of concern because even their presence in small amounts can kill corals and other reef organisms. Inadequate regulation of discharges by industries and mining activities is often responsible for pollution problems. Pollutants can originate from "point sources" such as discharge pipes above or under the water, or from "non-point sources" of rainwater runoff from roads, agricultural cropland and plantations.
