Sažetak
A healthy and balanced diet typically requires plenty of fruit in order to supply the human organism with vitamins, minerals, and bioactive compounds such as phytochemicals. Fruits are usually consumed fresh. Recently, freshly squeezed juices or technologically produced juices have been gaining more popularity. Dithiocarbamates (DTCs) were commercially used as fungicides during World War II, but they can also be used as pesticides. They are characterised by high chemical and biological activity, low production costs, low/moderate toxicity to humans, animals and crops, and they act against a broad spectrum of microorganisms. DTCs can be classified into three groups: dimethyldithiocarbamates (DMDC: ziram, thiram, and ferbam), ethylenebisdithiocarbamates (EBDC: maneb, zineb, and mancozeb) and propylenebisdithiocarbamates (PBDC: propineb). For DTC market monitoring, 104 samples of fruits (strawberries, apples, blueberries, pears, plums, peaches, nectarines, grapefruits, oranges, kiwis, and bananas) were sampled and analysed by gas chromatograpy-mass spectrometry (GC-MS). DTCs are not stable and cannot be extracted or analysed directly. Therefore, the method for the determination of intentionally produced carbon disulphide (CS2) in laboratory by control reaction in chemical bottle was developed and validated. Results obtained by this method satisfy the given criteria of acceptability. Obtained results showed that 21 samples had DTCs above limit of quantitation (LOQ), but none was above the maximum residue limits (MRLs) established by EU regulation (2017/171).
