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.
What respiratory effects can sulfur dioxide and nitrogen oxides cause?
They can irritate the respiratory system, causing breathing problems and worsening conditions such as asthma.
How can increased concentrations of sulfur dioxide and nitrogen oxides affect health risks?
They can increase human exposure and the resulting health risks.
How do sulfur dioxide and nitrogen oxides contribute to acid rain?
They react with oxygen and water in the atmosphere to form acids, making precipitation more acidic.
What are three effects of acid rain?
It can damage plants, harm aquatic ecosystems and erode buildings.
