Rückstandstoxikologische Probleme beim Einsatz von Ethylen-bis-dithiocarbamat-Fungiziden im Gemüseanbau unter Berücksichtigung der Ethylenthioharnstoff-Rückstände

The influence of single and repeated oral administration of ethylenethiourea (ETU) on hematologic parameters of the peripheral blood and the bone marrow was studied in male and female rats. Effects of single treatment on the erythrocytic system were initially indicated by increase in red blood cell count, hemoglobin concentration and hematocrit of the peripheral blood. The initial polyglobulia was followed by a decrease in the blood hemoglobin concentration and the number of erythroblasts of the bone marrow. Continuous administration of ETU resulted in hyporegenerative anemia. The white blood picture showed leukopenia after single and continuous administration of the substance. This effect resulted from a decline in lymphocyte numbers which occurred both in the peripheral blood and in the bone marrow. The hematologic changes were induced with 50 mg ETU/kg body weight and more using single treatment and 600 ppm (= 70 mg ETU/kg body weight) and more under dietary administration.

The cultivation of vegetables under glass and plastics is one of the most intensive application fields of pesticides and chemicals for regulation of biological processes. Therefore it may potentially occur a relatively high residues contamination of the crops. The author reveals in a survey the residue situation of usual insecticides, acaricides, fungicides, and chemicals for regulation of biological processes on tomatoes, cucumbers, and lettuce in comparison with the maximum residue limit after cold fogging application. The residues of benomyl, carbendazim, and ethylen-bis-dithiocarbamate are detailed discussed in the light of the latest toxicological findings. The results the residues of 11 agents on the crops show that after the corresponding preharvest interval the residues constitute 1.7-78% of the maximum residue limit. The conclusion is drawn that the cold fogging application of the agents under glass and plastics does not result in food hygienic toxicological problems.
