Primary & Secondary pollutant. Definition: A primary pollutant is an air pollutant emitted directly from a source. A secondary pollutant is not directly emitted as such, but forms when other pollutants (primary pollutants) react in the atmosphere.
Secondary poisoning refers to the exposure of non-target animals and people to the effects of the anti-coagulant ingredients of the rat poison. Wildlife and pets can consume rat carcassesâor the poison bait itselfâ which retain high levels of the poisons and in turn be sickened and die.
