Evaluation of the Content of Selected Elements in Herbs Cultivated in Organic Farms in the Lublin Region

Herbal raw materials are widely used in the food, pharmaceutical and cosmetic industries. In the presented studies the content of selected elements in the herbs originating from organic farming in the Lublin region was determined. The research was done for three different herbs: common thyme, pink rock-rose, and nettle by means of an ICP OES SpectroBlue spectrometer. It was shown that the content of heavy metals in the tested samples does not exceed generally accepted norms. The amount of trace in the tested herbs is too low for human health to be the main source to meet the demand. However, they may be a supplement of a daily diet.
