Resumen

Dithiocarbamates (DTCs) are a group of organosulfur compounds used mainly as pesticides to control fungal diseases in agricultural crops. In addition to this, DTCs are used as vulcanization additives in rubber manufacturing, additives in lubricants or antioxidants, among others. DTCs are classified according to their organosulfur skeleton, since the main difference between them is due to the elements present in their sulfur carbon skeleton, which can be Zn, Mn, Fe, Na or Se. Abuse in the use of DTCs can pose a risk to consumers, when the concentration in food is high. It can also be harmful to agricultural workers, either by inhalation or dermal exposure. This work uses the PRISMA methodology to perform a systematic review on the determination of DTCs residues in Brassica plants where 8 articles have been found, in which different methods and analytical techni- ques are used for the determination of DTCs. The most common analytical methods are UV-visible spectrophotometry, inductively coupled plasma mass spectrometry, liquid chromatography or gas chromatography. Some of the methods focus on determining the fungicide ethylene-bis-dithiocarbamate. Others focus on the determination of pencycurum, a fungicide of the phenylurea group, used for the treatment of fungi. Methods based on the extraction of the ammonium Se-pyr- rolidine-dithiocarbamate complex have also been found. The presence of DTCs is expressed as CS2. The main drawback is due to the fact that plants of the Brassica genus present sulfur in their structure and can generate phytogenic CS2 and generate errors in the quantification, giving rise to false positives. In addition to this, another drawback is the inability to differentiate between the different DTCs.
