  Abstract:   This paper presents recent data on soil contamination with Pb, Cd, Cu and Zn at 5 and respectively 30 cm in depth and the pollution of surface waters in two protected areas in Maramureş County. The measured values are presented in comparison with the limits defined by the Romanian legislation. In the case of Creasta Cocoşului reservation, lead pollution reaches the intervention limit at 5 cm in depth and it exceeds the alert threshold at 30 cm. Lead contamination in Chiuzbaia reservation is also high at the 30 cm in depth, the Cd content exceeds the alert limit, while the values for Cu, Zn and Mn are over the normal admitted values. The high level of contamination with heavy metals of these areas is mainly related to local mining activities and non-ferrous metals concentrates processing.

Keywords: soil pollution, heavy metals, natural protected areas
