Major effects on humans are caused by Los Angeles and London type smog, along with which two pollutants?

The correct answer highlights the significant pollutants associated with major smog types and their detrimental effects on human health. Los Angeles and London type smog are primarily influenced by specific air pollutants, particularly sulfur dioxide and nitrogen oxides, which contribute to respiratory issues and other health concerns in humans.

In the context of urban smog, sulfur dioxide is a significant contributor, known for its role in the formation of acid rain and its ability to irritate the respiratory system, leading to issues such as asthma and bronchitis. The presence of nitrogen dioxide in the atmosphere, often resulting from vehicle emissions and industrial activities, is also crucial. It can lead to the formation of ground-level ozone, causing respiratory problems and exacerbating existing health conditions.

The other options include pollutants that, while may also be harmful, do not specifically align with the primary components contributing to Los Angeles and London smog conditions. Understanding the relationship between these pollutants and health impacts is key for environmental health professionals in their assessment and mitigation efforts in urban environments.
