TCEQ has released two new DSDs for public comment, covering ethylene glycol and ethylene dichloride. The DSDs are used by TCEQ to inform the derivation of inhalation Effect Screening Levels (ESLs), chemical concentrations in the air that are considered safe for the general population (including vulnerable sub-populations) and that also protect against ‘welfare effects’ (e.g. on plants).
