[Comment] There were data gaps in the screening assessment for the sub-populations of hobbyists, workers, and their families. The amount of pigment used in hobbies should be investigated. Industry should be required to submit data on occupational exposure. [Response] 
With regards to hobbyists, the screening assessment indicates that the use of artists’ paints that contain these pigments or activities such as automotive restoration and repair of vehicles painted with these pigments could lead to increased exposure. However, information is not available to further quantify these exposures. The Surface Coating Materials Regulations under the Hazardous Products Act (Canada 2005) limit the total lead concentration to not more than 600mg/kg when a dried sample is tested. This requirement does not apply to the above situations (touch-up paints for metal surfaces or materials used in arts, crafts or hobbies, unless it is for children). Those types of products may exceed the 600 mg/kg lead limit but must display a specified warning on the product label. In terms of residents in close proximity to industrial facilities manufacturing or using these pigments, since theses pigments have negligible vapour pressure, any industrial releases would be in the form of particulates which would be expected to settle before significant transport had occurred. Extremely conservative estimates of exposure through ambient air predicted a low concentration of 0.36 μg/m3. The information gathered through the Challenge may be used as the basis for additional actions to minimize exposure of workers through the appropriate federal and/or provincial statutes. Information was not available regarding the possibility of transfer of these pigments to workers homes
