Major effects on humans include Los Angeles- and London-type smog, along with what two pollutants?

• A. Carbon monoxide and ozone
• B. Nitrogen dioxide and carbon dioxide
• C. Sulfur dioxide and hydrogen fluoride
• D. Particulate matter and methane

Answer: (D)

The major effects on humans from smog, particularly Los Angeles- and London-type, are primarily linked to particulate matter and methane. Particulate matter is a significant contributor to air pollution, affecting respiratory health and leading to other serious health issues. It can penetrate deep into the lungs and even enter the bloodstream, causing a range of cardiovascular and respiratory problems. Methane, while primarily a greenhouse gas, can contribute to air quality issues when it undergoes photochemical reactions in the atmosphere leading to the formation of ground-level ozone, a key component of smog. While methane itself is not a direct pollutant in the same way that particulate matter is, its role in the formation of secondary pollutants can have human health implications. Understanding how these pollutants interact and affect air quality is vital for addressing human health concerns related to smog, thus making particulate matter and methane a relevant pair of pollutants regarding the effects of smog in urban environments.
