toxicant
Man-made poisonous agent
A toxicant is a poisonous substance, especially one produced artificially or introduced into the environment through human activity: Industrial toxicants contaminated the groundwater.
The term distinguishes human-made or human-distributed poisons from naturally occurring toxins.
Scientists and regulators use toxicant when discussing pollution, pesticides, and chemical hazards.
