PAN International list of highly hazardous pesticides

PAN International list of highly hazardous pesticides. The number of active ingredients on the PAN HHP List changes over time. The reasons for changes are mainly changes in classifications made by organisations referred to in this list such as WHO, EU, EPA or IARC. In 2010, for example, more pesticides were classified as toxic to bees and as persistent. In 2013, numerous substances, which are not agricultural pesticides or obsolete, were deleted. Even though 12 pesticides were added to the 2015 version due to new data or classification changes the June 2015 version was significantly shorter than versions before 2014.
