Deutsch: Formaldehyd / Español: Formaldehído / Português: Formaldeído / Français: Formaldéhyde / Italiano: Formaldeide

Formaldehyde is a highly reactive, volatile organic compound (VOC) that is widely used in industrial applications and consumer products. In the environmental context, formaldehyde is a significant air pollutant that affects indoor and outdoor air quality. It is both a naturally occurring substance and a byproduct of human activities such as manufacturing, vehicle emissions, and the burning of fossil fuels. Formaldehyde is known for its harmful health effects, including irritation of the respiratory system and being classified as a carcinogen.

In the environmental context, "fossil" generally refers to the remains or impressions of prehistoric organisms, such as plants and animals, that have been preserved in rock or sediment. Fossils can provide important information about the evolution and history of life on Earth, as well as about past environmental conditions.

A fossil fuel is a fuel, such as coal, oil, and natural gas, produced by the Decomposition of ancient (fossilized) plants and animals; compare to alternative energy.

- Fossil fuel combustion : A Fossil fuel combustion is Burning of coal, oil (including gasoline), or natural gas.

Fossil Fuels are the nation"s principal source of electricity. The popularity of these fuels is largely due to their low costs. Fossil Fuels come in three major forms-coal, oil

Deutsch: Gießerei / Español: fundición / Português: fundição / Français: fonderie / Italiano: fonderia

Foundry in the environmental context refers to an industrial facility where metals are cast by melting them into a liquid, pouring them into a mold, and allowing them to solidify. These facilities are significant sources of environmental pollutants, including air and water emissions, and solid waste, due to the nature of their operations.

Deutsch: Fracking / Español: Fracturación hidráulica / Português: Fraturamento hidráulico / Français: Fracturation hydraulique / Italiano: Fratturazione idraulica

Fracking (hydraulic fracturing) in the environmental context refers to a method used to extract oil and natural gas from deep underground rock formations, primarily shale. This process involves injecting high-pressure fluid, typically water mixed with chemicals and sand, into the rock to create fractures, allowing oil or gas to flow more easily to the surface. While fracking has increased energy production in many countries, it has also raised significant environmental concerns related to water contamination, air pollution, and seismic activity.

Deutsch: Fragmentierung / Español: Fragmentación / Português: Fragmentação / Français: Fragmentation / Italiano: Frammentazione

Fragmentation in the environmental context refers to the process by which large, continuous ecosystems, such as forests, grasslands, or wetlands, are broken into smaller, isolated patches due to human activities like urbanisation, agriculture, and infrastructure development. This disruption often leads to ecological imbalance, impacting species diversity and habitat connectivity.
