Particular emphasis
has been put on the shortcomings in the currentmainstay of risk assessment.
Nomatter how precautionary itmay seemfor the separate pesticides,
risk assessment today widely disregards how different chemicals
may add up or even act together to produce an effect (Kortenkamp,
2007; Kortenkamp et al., 2009; Reffstrup et al., 2010) and only certain
chemicals sharing a common mode of action are subject to cumulative
risk assessment (US EPA, 1999)
