Question

which element is also an air pollutant? lead zinc copper silver

Explanation:

Lead is a heavy metal that can be released into the air from various sources such as industrial processes, vehicle emissions (in the past when leaded gasoline was used), and waste incineration. It is a well - known air pollutant that can have harmful effects on human health (e.g., neurological damage, especially in children) and the environment. Zinc, copper, and silver are not typically considered major air pollutants in the same sense as lead. While they can be present in the environment in small amounts from natural and anthropogenic sources, their presence in the air does not have the same widespread and significant negative impacts as lead.
