The pomological characteristics are very important for each type of fruit. The different types of fruits are being classified according to their shape, size, dimensions and the other features. The purpose of this paper is to examine the pomological characteristics of the peach fruits from ''Cresthaven’’ cultivar, from Rosoman, Republic of Macedonia. The fruits are being collected in full technological maturity. The following characteristics have been determined: height, width and thickness of the fruit (using a caliper with an accuracy of 0.01 mm), weight of the fruit and weight of the mesocarp and pit (using an analytical balance with an accuracy of 0.001 g), and the yield is also mathematically calculated. Also, during the research have been conducted an analysis for the presence of heavy metals (Pb, As and Cd) in the fruits (using atomic absorption spectrometer). The research was repeated three times, in a period of three years (2011, 2012, 2013). In the three-year period of examinations, from a statistical point of view, between the calculated values of the examined parameters of the peach fruits there are no statistically significant differences, with the exception of the pit weight and the yield, for which statistically significant differences have been determined. The contents of Pb, As and Cd in the fruits in three-year testing period are in accordance with the applicable rules and prescribed norms for food safety in the Republic of Macedonia.
