Question

question 5
legionaires disease is caused by__________.
pesticides
indoor biological contaminants
radon
primary pollutants

Explanation:

Legionnaire's disease is caused by Legionella bacteria, which are a type of indoor biological contaminant. These bacteria can grow in water systems such as cooling towers, hot water tanks, and plumbing systems. When aerosolized (turned into small droplets that can be inhaled), they can cause the disease. Radon is a radioactive gas, pesticides are chemical substances, and primary pollutants are directly emitted pollutants (not biological in nature for this context).

Answer:

Indoor Biological Contaminants
