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: 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.
Deutsch: Messung / Español: Medición / Português: Medição / Français: Mesurage / Italiano: Misurazione
Metering in the environmental context refers to the process of measuring, monitoring, and recording various environmental parameters such as energy consumption, water usage, emissions, and resource utilization. This data collection is critical for managing resources efficiently, ensuring compliance with environmental regulations, and supporting sustainability initiatives.
Methane (CH4) is a hydrocarbon that is a greenhouse gas with a global warming potential most recently estimated at 21. Methane is produced through Anaerobic (without oxygen) decomposition of waste in landfills, animal digestion, decomposition of animal wastes, production and distribution of natural gas and petroleum, coal production, and incomplete fossil fuel combustion.
