This paper deals with determining nitrates (III) and (V), lead and cadmium in 10 apple, 10 plum, 12 strawberry, 12 raspberry, and 10 white grape samples. Examined products originated from allotment gardens localized in the center of Lublin as well as in its surroundings. Among the analyzed fruits, the highest nitrate (III) contents were found in plums and white grapes harvested from the allotments located outside the city. Regardless of the harvest site, the highest content of nitrates (V) was recorded in strawberries. Exceeding permissible lead levels occurred in the majority of analyzed fruit samples, while in the case of cadmium, the permissible limit was exceeded only in white grape samples.

The aim of the study was to present and compare characteristics of pomological parameters, colour, dry matter and solids contents, as well as antioxidant activity of fruit of selected plum cultivars. Analyses were conducted on plums (Prunus domestica) of three cultivars: ‘Wegierka Zwykła’, ‘Bluefre’ and ‘Elena’. Presented morphological parameters of fruit and stones included their length, width and weight, as well as mean fruit size and firmness. Fruit colour was measured by spectrophotometry in the L*a*b* system. Contents of dry matter and solids were determined in fruits. Moreover, Trolox-equivalent antioxidant capacity (TEAC) of plums was assayed by colorimetry using a cation radical ABTS. The biggest fruits were found for cv. ‘Bluefre’, while the highest value of dry matter and solids contents – in cv. ‘Wegierka Zwykła’. Higher antioxidant activity (μM Trolox/g d.m.) was assayed in plums of relatively new cultivars, ‘Bluefre’ and ‘Elena’, in comparison to the traditional cultivar ‘Wegierka Zwykła’.
