What is radon and its significance in lung cancer?

Back

Radon is a colorless, odorless gas that is a decay product of uranium. It has been implicated as the cause of as much as 15 percent of lung cancer cases.

Front

What role does sulfur dioxide play in environmental issues?

Back

Sulfur dioxide is an important precursor to acid rain, which can harm ecosystems and structures.

Front

What is a persistent atmospheric inversion and its effect on air quality?

Back

A persistent atmospheric inversion occurs when a layer of warm air traps pollutants close to the ground, leading to poor air quality, especially from smoke.

Front

What are global reserves of oil and their expected depletion timeline?

Back

Currently proven global reserves of oil are expected to be largely exhausted within the next 50 years.

Front

What is asbestos and its health implications?

Back

Asbestos is a group of minerals composed of fibers known to cause lung disease, including asbestosis and lung cancer.

Front

Define acid rain and its primary components.

Back

Acid rain is precipitation that is significantly more acidic than normal, primarily due to sulfur dioxide and nitrogen oxides in the atmosphere.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases like carbon dioxide and methane.

Front

Explain the concept of air quality index (AQI).

Back

The AQI is a measure used to communicate how polluted the air currently is or how polluted it is forecast to become, based on various pollutants.

Front

What are the environmental impacts of coal mining?

Back

Coal mining can lead to habitat destruction, soil erosion, and water pollution, affecting local ecosystems and communities.

Front

What is the significance of renewable energy sources?

Back

Renewable energy sources, such as solar and wind, are crucial for reducing greenhouse gas emissions and combating climate change.
