toxicant

“These baits are designed to be slow, because if they kill the ants super fast, there won’t be enough time to pass the toxicants or insecticide to the queen and the rest of the colony.”

“Children’s development is exquisitely sensitive to toxicants. … It’s disappointing they’re not following the science.”

Other ingested toxicants, such as tainted food and contaminated drinking water, lead to body-first model of the disease.

This is partly due to the unrealistic expectation that scientists draw a direct, causal link between a substance and specific health effects, which would require unethically exposing people to toxicants and observing the outcomes.

"The potential role of environmental toxicants in influencing epigenetics and mast cell function is a complex and emerging area of research," they wrote.
