Analysis for pesticide residues in 24 fruit juice samples made from freshly squeezed fruits, taken during the years 2007 and 2008, from 8 different Montenegro locations and from 4 commercial juices was done. Also, in 12 samples, taken during the year 2008, heavy metal content was investigated. The method used for pesticides detection was based on matrix solid-phase dispersion (MSPD) with diatomaceous earth and analysis of extracts was performed by high performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS), with electrospray ionization. Analysis on heavy metal contents was done by the atomic absorption spectrometry (AAS). Presence of pesticide residues was detected in one third of the investigated samples, but in very low concentrations. The most frequently detected pesticides were Carbendazim and Dimethoate. Obtained values were at least 10 times lower than permitted values for fruits since fruit juices samples were made from freshly squeezed fruits. With the exception of 1 sample in which Pb content was over MRL of 0.3 mg/kg as defined by domestic regulations, content of heavy metals, Pb, Cd, Cu and Zn was below the permitted limit, so there was no significant metal contamination in tested fruit juices samples.
