Comparative assessment of plant protection products: how many cases will regulatory authorities have to answer?

Environmental Sciences Europe

Table 7 Potential number of cases for comparative risk assessment of plant protection products in Germany

Cases defined in terms of…		Counts
Cases defined in terms of…		For products containing any potential CFS	For products containing CFS identified by environmental hazard criteria^a
Products^b	Number of all candidate products	351	237
Products^b	Number of candidate products for which alternatives are available for one or more of their uses	345	232
Uses	Number of all authorised uses of candidate products	1,863	1,501
Uses	Number of authorised uses of candidate products for which alternative products are available	767	687
Products × Uses	Number of all candidate products times average number of uses^c	6,232	4,175
Products × Uses	Number of all candidate products times average number of uses for which alternatives are potentially available^c	2,569	1,910
Products × Uses × Alternatives	Number of all possible pairwise risk comparisons of candidate products with alternative products for all common uses^d	18,479	15,287

Scenario based on the status of authorised products in May 2013. ^aAs defined in the corresponding footnote to Table 4. ^bCandidate products are products containing one or more potential CFS; alternatives are products containing no potential CFS. ^cCalculated with non-rounded values for mean numbers of uses. ^dCalculated by multiplying the number of all candidate products with the average number of uses for which alternatives are potentially available and the mean number of such alternatives for every use; non-rounded mean values were used for the calculations.
