What poisonous gas is contained in the exhaust fumes from cars?

🧠 Explanation:

Carbon monoxide, a poisonous gas in car exhaust fumes, is a colorless, odorless compound formed by incomplete fuel combustion. Toxic even in low concentrations, it binds to hemoglobin, reducing oxygen delivery in the body, causing health risks like dizziness or death. Its presence in vehicle emissions has driven regulations for cleaner engines and catalytic converters. Understanding carbon monoxide’s dangers is key in environmental and public health studies, emphasizing the need for sustainable transport solutions. Its role in air pollution highlights the importance of emission controls to protect human health and the environment.
