Deutsch: Schwermetallbelastung / Español: Contaminación por metales pesados / Português: Contaminação por metais pesados / Français: Contamination par les métaux lourds / Italiano: Contaminazione da metalli pesanti
Heavy Metal Contamination refers to the accumulation of metallic elements with high atomic weights and densities in environmental matrices, posing significant ecological and human health risks. These contaminants originate from both natural processes and anthropogenic activities, persisting in soil, water, and air due to their non-biodegradable nature. Their toxicity varies depending on chemical speciation, concentration, and exposure pathways, necessitating rigorous monitoring and remediation strategies.
"Hedonic adaptation," also known as the "hedonic treadmill," is a concept primarily discussed in psychology and behavioral economics, referring to people's tendency to return to a stable level of happiness despite major positive or negative events or life changes. However, when considering hedonic adaptation in the environmental context, it can relate to how individuals or societies adjust their expectations and satisfaction levels in response to changes in their environment, including improvements or degradations in environmental quality.
The hedonic treadmill theory, originally a concept from the field of psychology, can also be applied in the environmental context to describe how continuous consumption and the pursuit of material wealth lead to unsustainable environmental practices without providing lasting increases in happiness. This theory suggests that people continuously adapt to improved circumstances without gaining long-term satisfaction, perpetually returning to a relatively stable level of happiness despite significant efforts or consumption.
Deutsch: Hubschrauber / Español: Helicóptero / Português: Helicóptero / Français: Hélicoptère / Italiano: Elicottero
Helicopter in the environmental context refers to the use of helicopters for various Environmental Monitoring, Conservation, and management activities, as well as the environmental impact of helicopter operations. Helicopters play a significant role in tasks such as wildlife monitoring, forest management, emergency response, and aerial surveys, but they also contribute to Air Pollution, noise pollution, and greenhouse gas emissions.

Hemp is a versatile plant species, Cannabis sativa, known for its strong fibres, seeds, and oil, which are used in various industrial and environmental applications. Unlike its psychoactive relative, marijuana, hemp contains minimal levels of THC, making it suitable for legal cultivation in many regions. Its environmental significance lies in its potential to support sustainable practices in Agriculture, industry, and ecological restoration.
Deutsch: Hepatotoxizität / Español: hepatotoxicidad / Português: hepatotoxicidade / Français: hépatotoxicité / Italiano: epatotossicità
Hepatotoxicity in the environmental context refers to liver damage caused by exposure to environmental toxins. This damage can result from chemicals, pollutants, or natural substances found in the environment that are toxic to the liver, the body's essential organ for detoxification and Metabolism.
Deutsch: Kraut / Español: Hierba / Português: Erva / Français: Herbe / Italiano: Erba
In the environment context, an "herb" refers to any non-woody flowering plant that does not develop persistent woody tissue but dies back at the end of the growing season. Herbs play a significant role in ecosystems, contributing to biodiversity and serving as key components in various habitats. They are usually distinguished from shrubs and trees due to their soft and flexible stems. Environmental herbs include a wide range of species, both wild and cultivated, that have culinary, medicinal, or ecological significance.
