Freshwater
Short Term Concentration (µg/L) 640,000 µg/L or 640 mg/L
Chloride toxicity to freshwater organisms was evaluated using tests with both CaCl2 and NaCl salts.
Derived with severe-effects data (such as lethality) and are not intended to protect all components of aquatic ecosystem structure and function but rather to protect most species against lethality during severe but transient events (e.g. inappropriate application or disposal of the substance of concern).
Long Term Concentration (µg/L) 120,000 µg/L or 120 mg/L
Chloride toxicity to freshwater organisms was evaluated using tests with both CaCl2 and NaCl salts.
Derived with mostly no- and some low-effect data and are intended to protect against negative effects to aquatic ecosystem structure and function during indefinite exposures (e.g. abide by the guiding principle as per CCME 2007).
The long-term CWQG may not be protective of certain species of endangered and special concern freshwater mussels (as designated by the Committee on the Status of Endangered Wildlife in Canada, or COSEWIC). This specifically applies to two species; the wavy-rayed lampmussell (Lampsillis fascialo) (COSEWIC 2010a) and the northern riffleshell mussell (Epioblasma torulosa rangiana) (COSEWIC 2010b) (Table 2). The wavy-rayed lampmussel is indigenous to the lower Great Lakes and associated tributaries, specifically western Lake Erie, the Detroil River, Lake St. Clair and several southwestern Ontario streams. The northern riffleshell mussel is indigenous to the Ausable, Grand, Sydenham and Thames River in Ontario, as well as the Lake St. Clair delta. Discussion with provincial regulators should occur if there is a need to develop more protective site specific values.
