Woher kommen Stickoxide in der Luft?
Eine der Hauptquellen für Stickoxide in der Atmosphäre sind Abgase, die bei der Verbrennung fossiler Brennstoffe, wie Kohle oder Öl, entstehen. In Europa wurden im Jahr 2000 mehr als die Hälfte, in einigen Städten, wie London, bis zu drei Viertel der NOx-Emissionen durch den Verkehr verursacht.
Is there a way to mitigate the environmental impact of mining?
This inherited legacy of environmental damage from mining is not indicative of the mining cycle today. Now, mine closure and a number of activities to mitigate the impacts of mining are an integral part of all metal mine planning and mineral development from the discovery phase through to closure:
What are the dangers of working in mines?
When mines collapse, the workers underground usually have low chances to survive since they will not have enough oxygen available and may also die from a lack of drinking water. Thus, working in mines can be quite dangerous and may even take your life. Hearing damages are another quite common effect when it comes to working in mines.
What happens when you drink water from abandoned mines?
This toxic water leaks out of abandoned mines to contaminate groundwater, streams, soil, plants, animals and humans. As a result an orange colour can blanket the river, estuary or sea bed killing plants and making surface water unusable as drinking water.
Why is open pit mining bad for the environment?
This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined. Environmental hazards are present during every step of the open-pit mining process.
