Atmospheric pollution is driven by:
Show answer Hide answer
Answer: B. CO
Explanation
Carbon monoxide is a toxic gas that acts as a major atmospheric pollutant worldwide. Incomplete combustion of carbon-based fuels is the primary driver of carbon monoxide emissions. Elevated ambient concentrations pose severe health risks to humans and animals breathing polluted air. Carbon monoxide binds hemoglobin in blood, drastically reducing oxygen transport capacity. Automobile exhaust, industrial processes, and domestic wood burning release significant CO volumes. Urban air quality management programs strictly monitor carbon monoxide pollution levels.
Congested traffic intersections frequently experience dangerous spikes in atmospheric carbon monoxide concentrations. Strict vehicle emission standards have successfully reduced carbon monoxide pollution in major cities. Indoor air pollution from unvented heaters poses severe health hazards in developing regions. Option A is incorrect because ozone is a secondary pollutant formed via photochemical reactions. Option C is wrong because carbon dioxide is a greenhouse gas rather than a toxic pollutant. Option D is inaccurate because nitrogen gas is a natural, non-polluting atmospheric component.
