Water Quality Guidelines for the Protection of Aquatic Life

Freshwater

Short Term Concentration (µg/L) 550,000 µg/L or 550 mg/L

All nitrate concentrations presented here will be for the ion only (i.e., as mg NO3-·L-1).  Conversion factors for some of the commonly reported units in the literature are provided in the factsheet.

For protection from direct toxic effects; the guidelines do not consider indirect effects due to eutrophication.

Derived from toxicity tests utilizing NaNO3

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) 13,000 µg/L or 13 mg/L

All nitrate concentrations presented here will be for the ion only (i.e., as mg NO3-·L-1).  Conversion factors for some of the commonly reported units in the literature are provided in the factsheet.

For protection from direct toxic effects; the guidelines do not consider indirect effects due to eutrophication.

Derived from toxicity tests utilizing NaNO3.

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).

Short Term Concentration (µg/L) 1,500,000 µg/L or 1500 mg/L

All nitrate concentrations presented here will be for the ion only (i.e., as mg NO3-·L-1).  Conversion factors for some of the commonly reported units in the literature are provided in the factsheet.

For protection from direct toxic effects; the guidelines do not consider indirect effects due to eutrophication.

Derived from toxicity tests utilizing NaNO3 and KNO3.

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) 200,000 µg/L or 200 mg/L

All nitrate concentrations presented here will be for the ion only (i.e., as mg NO3-·L-1).  Conversion factors for some of the commonly reported units in the literature are provided in the factsheet.

For protection from direct toxic effects; the guidelines do not consider indirect effects due to eutrophication.

Derived from toxicity tests utilizing NaNO3 and KNO3.

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).
