Additional information

Monitoring data was collected to assess the ambient and baseline Mo concentrations in the various environmental compartments.

For each environmental compartment, a realistic-worst-case Predicted Environmental Concentration (PEC) was derived using the median 90P across different countries.

Furthemore, the baseline concentrations were also reported for several environmental compartments.

Realistic-worst-case PECs for the various environmental compartments:

PEC freshwater = 2,3 ug/L dissolved

PEC freshwater sediment = 3,77 mg/kg dry weight

PEC soil = 0,86 and 1,04 mg/kg dry weight for agricultural and grazing lands, respectively

PEC marine water = 13,6 ug/L dissolved

PEC estuarine = 10,0 ug/L dissolved

PEC marine sediment = 14,1 mg/kg dry weight

Baseline concentrations for freshwater, sediment and soils based on the median 90P of the FOREGS data (EU countries)

baseline concentration for freshwater = 0,28 ug/L

baseline concentration for freshwater sediment = 0,58 mg/kg dry weight

baseline concentration for top soil = 0,59 mg/kg dry weight
