Human Health

Deutsch: Menschliche Gesundheit / Español: Salud Humana / Português: Saúde Humana / Français: Santé Humaine / Italiano: Salute Umana

Human Health refers to the overall physical, mental, and social well-being of individuals, not merely the absence of disease or infirmity. In the environment context, it specifically relates to how environmental factors—such as air quality, water purity, chemical exposure, and climate change—impact health outcomes. Environmental health assesses risks and develops strategies to mitigate harmful exposures and promote healthier living conditions.

Hydrocarbon

Deutsch: Kohlenwasserstoff / Español: Hidrocarburo / Português: Hidrocarboneto / Français: Hydrocarbure / Italiano: Idrocarburi
In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon.[1] Hydrocarbons from which one hydrogen atom has been removed are functional groups, called hydrocarbyls.[2] Aromatic hydrocarbons (arenes), alkanes, alkenes, cycloalkanes and alkyne-based compounds are different types of hydrocarbons.
The majority of hydrocarbons found on Earth naturally occur in crude oil, where decomposed organic matter provides an abundance of carbon and hydrogen which, when bonded, can catenate to form seemingly limitless chains.

Hydrocarbon Mixture

Deutsch: Kohlenwasserstoffgemisch / Español: Mezcla de Hidrocarburos / Português: Mistura de Hidrocarbonetos / Français: Mélange d'Hydrocarbures / Italiano: Miscela di Idrocarburi

A hydrocarbon mixture in the environmental context refers to a blend of various organic compounds primarily composed of carbon (C) and hydrogen (H) atoms. These mixtures can be of natural origin (e.g., crude oil, natural gas) or result from human activities (e.g., solvents, fuels, lubricants). Their environmental relevance stems from their potential impacts on air, water, soil, and living organisms.
