Glossary M
Deutsch: Metall / Español: Metal / Português: Metal / Français: Métal / Italiano: Metallo /
In the environmental context, 'metal' refers to a group of chemical elements characterized by their high electrical conductivity, malleability, and luster. Metals have various applications in industries and everyday life, but their extraction, use, and disposal can have significant environmental implications.
Deutsch: Metallgewinnung / Español: Extracción de metales / Português: Extração de metais / Français: Extraction des métaux / Italiano: Estrazione dei metalli
Metal extraction refers to the industrial processes used to obtain pure metals or metal compounds from naturally occurring ores or recycled materials. These processes are fundamental to modern manufacturing, infrastructure, and technology but often pose significant environmental challenges, including habitat destruction, pollution, and resource depletion. The balance between economic demand and ecological sustainability remains a critical concern in this field.
Deutsch: Metallverschmutzung / Español: contaminación por metales / Português: poluição por metais / Français: pollution métallique / Italiano: inquinamento da metalli
Metal pollution in the environmental context refers to the contamination of ecosystems with metallic elements that can be toxic to life. This type of pollution is primarily a concern due to the non-biodegradable nature of metals, which allows them to persist in the environment and potentially accumulate to harmful levels in the soil, water, and living organisms.
Deutsch: Metallrecycling / Español: Reciclaje de metales / Português: Reciclagem de metais / Français: Recyclage des métaux / Italiano: Riciclaggio dei metalli
Metal recycling refers to the process of recovering and processing used metals to produce new metal materials. This practice is crucial for environmental sustainability as it reduces the need for virgin ore extraction, decreases energy consumption, and minimizes waste and greenhouse gas emissions.
Deutsch: Metalltoxizität / Español: Toxicidad de metales / Português: Toxicidade de metais / Français: Toxicité des métaux / Italiano: Tossicità dei metalli
Metal toxicity refers to the harmful effects caused by excessive levels of certain metals in the environment, which can negatively impact human health, wildlife, and ecosystems. Metals such as lead, mercury, cadmium, and arsenic are particularly notorious for their toxic properties when they accumulate in living organisms.
