What are atmospheric particulates?
Tiny solid particles or liquid droplets suspended in the air.
How can atmospheric particulates harm human health?
Small particles can be breathed into the lungs, where they may irritate or damage the respiratory system.
How do atmospheric particulates cause global dimming?
They scatter or absorb sunlight, so less solar energy reaches Earth's surface.
How do sulfur dioxide and nitrogen oxides affect human health?
They irritate the respiratory system and can worsen breathing problems.
How do sulfur dioxide and nitrogen oxides contribute to acid rain?
They react with water and oxygen in the atmosphere to form acidic substances, leading to acid rain.
How does acid rain affect ecosystems?
It damages lakes and soils and harms plants and aquatic life.
How does acid rain affect stone and metal structures?
It can erode them.
Why is carbon monoxide difficult to detect by sight or smell?
It is colourless and odourless.
How does carbon monoxide reduce oxygen transport to body tissues?
It binds strongly to haemoglobin, reducing the blood’s ability to carry oxygen.
What can oxygen deprivation caused by carbon monoxide exposure lead to?
Serious harm or death.
How do increased atmospheric carbon monoxide levels affect the risk of exposure?
They increase the risk of exposure to harmful concentrations.
