The insecticide’s lethal potential revealed

Organic Esters are highlighted by the Doctor as another component enabling the insecticide to penetrate human systems. Alongside phosphoric acid and mineral nitrate, they contribute to the poison’s 'everlasting' properties, seeping into soil and water. The group’s discussion of these components reveals the formula’s deadly efficiency, with Barbara’s giddiness serving as a real-time demonstration of its effects. The esters’ role in the formula symbolizes the insecticide’s ability to infiltrate and persist, making it an invisible, systemic threat.
