Heavy Metal & VOC Studies

The supplier Sylva uses is constantly monitoring the impurity levels in the colorant manufactured at their facility. This colorant was analyzed for heavy metals and also for Volatile Organic Compounds (VOC). No detectable VOC levels have been found. The summary of heavy metals content and the data interpretation is presented as follows:

•Soil screening levels based on direct ingestion of soil.


•Based on heavy metals data - the concentrated colorant levels are below EPA Superfund soil screening levels (SSL). SSL levels were used as guidelines for this data interpretation.
