Priority Measures for Identification, Characterization, and Monitoring of PREPs.

	Identification	Characterization	Monitoring
Key data	Product name Launch date(s) and location(s)	Constituents and/or emissions Claims Design Marketing	Consumer response/perception Consumer uptake Sales
Priority Sources	Industry reports Trade publications Local tracking	Government disclosure Independent scientific testing	Sales and use data Population surveys
Secondary Sources	International market Newspapers Internet	Industry reports Internal documents and patents Correspondence Newspaper articles	Industry reports Newspaper reports Magazine advertising Government disclosures
Rationale	In order to identify potential PREP-type products on the market, data sources should be highly sensitive (at the cost of specificity) and provide real time information.	To effectively characterize PREP products, it is essential to have valid, independent information about the product’s characteristics.	Monitoring requires reliable and consistent sources of information to identify trends and changes over time as well as the impact of products on the population (through tracking marketing and consumer perceptions).
