Question

match each pollutant with its source. match term definition carbon monoxide a) burning gas in closed area nitrogen oxides b) made when it reacts to oxygen particulate matter c) emissions from oil refineries sulfur oxides d) from roadways, fields, or construction sites

Explanation:

• Carbon monoxide (CO) is often produced by burning gas (like in faulty heaters) in closed areas (A), as incomplete combustion in such spaces leads to CO.
• Nitrogen oxides (NOₓ) form when nitrogen reacts with oxygen (B), typically in high - temperature processes like combustion in engines.
• Particulate matter (PM) comes from roadways (vehicle emissions), fields (agricultural dust), or construction sites (dust from building work) (D).
• Sulfur oxides (SOₓ) are emitted from oil refineries (C) as they process sulfur - containing fuels.

Answer:

• Carbon monoxide - A) Burning gas in closed area
• Nitrogen oxides - B) Made when it reacts to oxygen
• Particulate matter - D) From roadways, fields, or construction sites
• Sulfur oxides - C) Emissions from oil refineries
