The toxic effects were attributed to HCl formation, as benzotrichloride dissociates rapidly into the far less toxic benzoic acid and HCl on water exposure. Compensating the pH decrease in water from the HCl negated toxic effects, suggesting that water acidification is the reason for the low aquatic life toxicity. [20]
