The Canadian Council of Ministers of the Environment (CCME) developed chloride toxicity thresholds for protection of aquatic in 2011 based on a comprehensive scientific review (provide link), as follows: '''''Chronic toxicity''''' (long duration exposure): 120 mg/L'''''Acute toxicity''''' (short duration exposure): 640 mg/L

The [https://sustainabletechnologies.ca/app/uploads/2014/05/CWQG_chlorides.pdf Canadian Water Quality Guidelines for the Protection of Aquatic Life]<ref>Canadian Council of Ministers of the Environment. 2011. Canadian water quality guidelines for the protection of aquatic life: Chloride. In: Canadian environmental quality guidelines, 1999, Canadian Council of Ministers of the Environment, Winnipeg. https://sustainabletechnologies.ca/app/uploads/2014/05/CWQG_chlorides.pdf</ref> document from the Canadian Council of Ministers of the Environment (CCME) is another valuable paper that discusses the direct toxic effects of chloride, based on studies using NaCl and CaCl<sup>2</sup> salts. The guideline can be used as a screening and management tool to ensure that chloride does not lead to the degradation of the aquatic environment. Further guidance on the application of these guidelines is provided in the scientific criteria document (CCME 2011), which can be found here - [https://www.ccme.ca/fr/res/2011-chloride-ceqg-scd-1460-en.pdf Scientific Criteria Document - Cl Ion]. Both documents developed chloride toxicity thresholds for protection of aquatic in 2011 based on a comprehensive scientific review.
