Vegetable has an important role in human nutrition. Various parts of the plants have been part of the human diet since the beginning. Vegetables have a number of properties that make its consumption very healthful. It not only is a good source of vitamins, minerals and fiber but also contains protective components so called phytonutrients, has an antioxidant and antimicrobial effects. Daily intake of vegetables offers many health benefits, helps to improve health for example the function of digestive and immune system, reduces the risk of various diseases and so we should take care to its regular consumption. It is widely used, except that it is the basic raw material for the preparation of foods and is also an important raw material for the processing industry. Nowadays has become environmental pollution by heavy metals as a big problem. The contamination of water, soil as well as air pollution by heavy metals negatively affects agricultural production and production of non-harmful to health, safe and quality food, which may be adverse effects on human health. Therefore, it is important that we devote this issue more attention. The aim of this work was to identify and determine content of heavy metals in selected vegetables. Defined objectives have been achieved by analyzing of selected species samples of root from brassica vegetables: carrot (Daucus carota L. ssp. sativus), parsley (Petroselinum hortesne HOFFM conv. radicosum), kohlrabi (Brassica oleracea L. var. gongylodes), celery (Apium graveolens L. var. rapaceum) and beetroot (Beta vulgaris L. var. conditiva ssp. vulgaris). The crops were bought in local market. The obtained results were compared with the results obtained from analyzes of vegetables that were grown in home conditions respectively from markets of local growers. All crops were grown in Slovak Republic. By using Varian AA 240FS and AAS method were analyzed the contents of risk metals in selected vegetables. It was confirmed that in selected types of vegetables analyzed element was not exceeded the limit values established by Codex Alimentarius of Slovak Republic. From the results, also can be concluded that higher contents of heavy metals (Cu, Mn, Ni, Cd, Pb) were mostly in samples from home gardeners than in samples came from local market.
