Updated document: Polycyclic Aromatic Hydrocarbons 2010
The CSoQG PAH has been revised to improve the understanding of how to implement the PAH soil quality guidelines. Figures 1,2, and, Figures 8-1 and 8-2 were added to the Factsheet and supporting criteria document, respectively. In addition, errors in Tables 7-9 and 7-10 of the supporting scientific document were corrected.

Updated document: Ammonia
In the footnote to Table 2 the factor used to convert total ammonia concentration to nitrogen has been corrected, 0.8 should be 0.8224.
The value in Table 3 for cell pH 7.0, temperature 5°C has been corrected. 1.125 should be 0.125.
On page 6 in the section on Total Ammonia, the pH range was changed from pH (6.0-9.5) to pH (6-10.0) to agree with Table 2.

Updated document: CSoQG Selenium
Replacing CSoQG Selenium 2007
Corrections have been made to the direct human health-based soil quality guideline (SQGDH) for two land uses, and to the soil quality guideline for human health (SQGHH) for one land use:
1. The SQGHH for commercial land use decreased to 125 mg•kg-1 from 300 mg•kg-1
2. The SQGDH for commercial land use decreased to 125 mg•kg-1 from 300 mg•kg-1
3. The SQGDH for industrial land use decreased to 4075 mg•kg-1 from 9770 mg•kg-1 as reported in the scientific criteria document.
4. The value of 1135 mg•kg-1 for SQGDH industrial land use reported in the factsheet was incorrect and has been revised to 4075 mg•kg-1.
Note that the final Canadian soil quality guidelines for the protection of environmental and human health – Selenium have not changed (final soil quality guidelines for all land uses are based on soil quality guidelines for environmental health).
The posted document has been revised to reflect these corrections. For more information, consult the abstract section (page viii, English, page x, French), of the revised selenium scientific criteria document. (CCME 2009. Canadian Soil Quality Guidelines: Selenium. Environmental and Human Health. Scientific Criteria Document.)
