The European Union's Water Framework Directive - A new challenge in monitoring water quality. Ramowa Dyrektywa Wodna Unii Europejskiej - Nowe wyzwanie w monitoringu jakości wody
PublicationMonitoring jakości wody polega zwykle na punktowym pobieraniu próbek z użyciem odpowiednich próbników, po którym następuje etap analizy w celu określenia stężenia zanieczyszczeń. Pomimo wielu zalet, metoda ta ma ograniczenia w zakresie badania rozkładu czasowego i przestrzennego zanieczyszczeń oraz w zakresie oceny biodostępności zanieczyszczeń. Wdrożenie Ramowej Dyrektywy Wodnej (2000/60/EC)w krajach Unii Europejskiej będzie wymagało...
