โœฆ Synopsis


The aim of the investigations was the determination of the lead, cadmium, copper, iron, zinc and magnesium content in some vegetables in an industrial region (Cracow) and in an agricultural region far from industrial centres (control). It was found that all the vegetables analysed contained lead and cadmium contaminations. The average lead concentration in parsley-haulm and parsley-root and cadmium concentration in beets, onion, parsley-haulm, leek, lettuce and potatoes coming from the Cracow region exceeded the permissible norm. In the vegetables from the Cracow region the levels of the determined trace elements were higher ( P < 0.01) than that of the controls.

Zusammenfassung

Bestimmung des Gehaltes einiger Spurenelemente in Gemiise aus unterschiedlich kontaminierten Gebieten Ziel der Untersuchungen war die Bestimmung der Gehalte von Blei, Cadmium, Kupfer, Eisen, Zink und Magnesium in einigen Gemiisearten aus einem Industriegebiet (Krakau) und aus einem von Industriezentren entfernten landwirtschaftlichen Gebiet (Kontrolle). Alle untersuchten Gemiisearten waren mit Blei und Cadmium kontaminiert. Die durchschnittlichen Bleigehalte in Petersilienstengeln und -wurzeln und die Cadmiumgehalte in Ruben, Zwiebeln, Petersilienstengeln, Porree, Kopfsalat und Kartoffeln (alle Gemiise aus dem Raum Krakau) iiberschritten die zulassigen Werte. In den Gemiisearten aus dem Raum Krakau lagen die Gehalte an den Spurenelementen iiber denen der Kontrollen ( P < 0,Ol).

Current publications tend to make little reference to early work in their ยฎeld. The study of the contamination of the food chain by trace elements is no exception. It is suggested that among the reasons for the lack of early citations are the reliance on library databases, the need to keep lists of
