Land based dissemination of ZnCdS by the United Kingdom Ministry of Defence sampled by fallout impactors at near distance (<300 m) and cascade impactors at 25 and 50 miles
| Field report FR | Material disseminated (g) | Material recovered from disseminator (g) | Location | Additional Cd load to soil (μg Cd/g soil DM, or related to FR 370) | Area above legal maximum concentration* |
|---|---|---|---|---|---|
| *Assuming critical addition is about 85 μg/cm2, which is roughly equal to +2.3 mg/kg soil DM, assuming baseline soil concentration is 0.7 mg/kgDM. | |||||
| †There is confusion in the report over units. The higher values refer to the unlikely assumption that the units are μg/Petri dish, rather than mg/m2. | |||||
