Sediment database for storing data regarding ammunition dumping sites in Sweden

By order of the Swedish Armed Forces Environmental Department - the Swedish acronomy HKV/GRO/Miljö - FOI, the division of NBC Defence, has analyzed surface sediment samples from dumping grounds in lakes and at sea, as well as studied and computerized the results in a user-friendly environment specially developed for this purpose. The analyses have been conducted with respect to the metals arsenic, lead, cadmium, copper, chromium, mercury, nickel and zink and, too, the explosives TNT, 2,4-DNT and sA-4,6-DNT. The results are presented in table form. In order to further illustrate them in map form, the classification of the Swedish Environmental Protection Agency was applied. The investigation revealed that the sediments had normal metal content except in a few cases where very heavy content was measured. heavy metal content is found in certain overloaded areas and can thus not be linked to the dumped ammunition. No detectable content of analyzed explosives could be demonstrated.
