Abstracts

EN

Environmental contamination with heavy metals as a result of anthropogenic activities is not a recent phenomenon. Contaminated sites with heavy metals can be found in functioning as well as abandoned industrial (brownfield) territories, landfills, residential areas with historical contamination, road sides and rarely in polluted sites by natural activities. Pollution data on its amount and concentrations is known from historical studies and monitoring nowadays, but it should be periodically updated for the use of territorial planning or in case of a change of the land use. A special attention should be paid to heavy metal contamination, because in many cases this contamination is most problematic for remediation. 242 territories now are numbered as contaminated and fixed in the National Register of contaminated territories - at least 56 of them are known as contaminated with heavy metals in different amount and concentration. Legislative aspects are discussed as well as an overview of soil and groundwater contamination research and the possible remediation technologies in Latvia are given. Two case studies are described in order to give the inside look in pre-investigations done before potential start of heavy metal remediation works.

Zanieczyszczenie środowiska metalami ciężkimi, w wyniku działalności człowieka, nie jest nowym zjawiskiem. Miejsca skażone metalami ciężkimi można znaleźć na wielu obszarach, m.in. na terenach poprzemysłowych, składowiskach odpadów, obszarach mieszkalnych, poboczach dróg, rzadziej zanieczyszczenia pojawiają się w sposób naturalny. Poziom zanieczyszczeń można ocenić na podstawie źródeł historycznych, a także na podstawie współczesnych badań. Informacje o zanieczyszczeniach powinny być okresowo aktualizowane na użytek planowania przestrzennego lub w przypadku zmian sposobów zagospodarowania. Szczególną uwagę należy zwrócić na zanieczyszczenia metalami ciężkimi, ponieważ w wielu przypadkach właśnie ten rodzaj zanieczyszczeń jest najtrudniejszy w remediacji. Obecnie wymienia się 242 obszary skażone, wpisane do Krajowego Rejestru Skażonych Obszarów - co najmniej 56 z nich to obszary skażone różnymi ilościami metali ciężkimi, występujących w różnych stężeniach. Przedyskutowano aspekty prawne, a także wyniki badań zanieczyszczenia metalami ciężkimi gleby i wód gruntowych na Łotwie oraz omówiono ewentualne technologie remediacji. Opisano dwa przykłady wstępnych wyników badań, poprzedzających remediację metali ciężkich.
