Definition - What does Heavy Metals mean?
Heavy Metals are elements emitted during the production, processing and use of oil and natural gas. They get accumulated in the sediments around offshore oil and gas production sites. Some of these elements, like mercury, may lead to the damage of the processing equipment. These Metals are present in the earth’s crust and they are becoming more concentrated due to human activities.
Heavy Metals enter a water supply through consumer and industrial waste that breaks down the soils and releases them into lakes, streams and ground water.
Petropedia explains Heavy Metals
Heavy Metals are metallic chemical elements that have a relatively high density and are poisonous at low concentrations. They are actually natural components of the Earth's crust and are impossible to destroy. They may enter a human body through food, water and air as well. Some of the perilous chemicals emitted during the production or processing or use of oil and natural gas are Benzene, Sulphur Dioxide and Petroleum Coke, Formaldehyde, Nitrogen Oxides, Mercury, Radon and Hydrogen Fluoride, etc. Exposure to these Heavy Metals may increase the threats to public health including cancers and damage to immune system.
