factor D Degradation factor
Selection of dangerous substances on the basis
of sales data, use and environmental behaviour
through the use of indexes of priority (IP and
I_EXP)

Planning and execution of the surveillance
monitoring for surface and groundwaters

• Existing
• monitoring scheme
• for surface and groundwaters
• only few data on pesticides
• analytical protocols
• some classical chlorinated hydrocarbons
• Atrazin
• Simazin
