Abstract

In our study the focus was on determining the level of toxic heavy metals such as Pb, Mo, Cd and Hg in tomato fruit at one commercial hybrid - Adriatic F1 and nine new hybrids grown under identical conditions in a greenhouse. Depending on their concentration and capacity for bioaccumulation, they can provide a range of health risks. The concentration of heavy metals in the research was determined by flame atomic absorption spectrophotometry. Average concentrations of heavy metals varied in factors from hybrid, the lowest concentration of lead (11.96 µg/kg), molybdenum (26.25 µg/kg) and cadmium (7.41 µg/kg) and mercury (0.86 µg/kg),
is found in the hybrid marked as 140, while the highest concentration of cadmium (39.23 µg/kg) in the hybrid 116, while the maximum concentration of lead (40.99 µg/kg), molybdenum (96.64 µg/kg) and mercury (3.08 µg/kg) was measured in the commercial hybrid Adriatic F1. Pearson's correlation coefficient showed that there is a strong positive correlation between molybdenum and mercury(r 0.83), and a medium-strong positive correlation between molybdenum and lead (r 0.69), mercury and cadmium (r 0.52) and mercury and lead content (r 0.64) in fruit. The obtained results suggested that the increase of the metal concentration in tomato fruits can be conditioned by the genetic predispositions of the plants.
