Additional information

In the aquatic environment, the effects of HCl are clearly related to the pH effect, as HCl will dissociate fully in H3O+ & Cl- ions, of which the latter is not a harmful substance. The substance cannot be measured accurately in the body since chlorine ions are already very abundant, and excretion of chlorine via the urine/faeces is high. Therefore, this study is considered scientifically unjustified for this substance.
