Carbaryl was applied three times at 15 days interval to cauliflower (Brassica oleracea var. botrytis L.), and its persistence was determined spectrophotometrically at 0, 1, 3, 6, 10, and 15 days after the first and last treatments. In unprocessed cauliflower the prescribed tolerance level for carbaryl residues of 5 ppm was only reached on the sixth day, in processed cauliflower on the third day after application. Pretreatment with washing + boiling/cooking on the other hand led to a considerable decrease of the carbaryl residues already on the day of application. The lower carbaryl values encountered in all variants after the last application are attributed by the authors to a thinning effect due to an increased cauliflower mass.

This experiment has clarified the ultrastructural pathology, by scanning (SEM) and transmission electron microscopy (TEM), induced by 1-naphthyl-N- methylcarbamate (carbaryl) in the gills of juvenile goldfish (Carassius auratus Linneaus). Carbaryl is a low toxicity pesticide commonly used in forestry and agriculture and for controlling aquatic weeds and crustacean predators of shellfish, and has been known to cause gill damage in fish and clams. A variety of cellular changes were observed after exposure of goldfish for 96 h to a sublethal dose of 10 mg carbaryl/l of water. SEM revealed secondary lamellar fusion, distortion, thinning, and mucus release. TEM responses included enlargement of subepithelial lymphatic spaces and mitochondrial disruption and distortion of the lamellar covering epithelium. Pillar cells became detached and chloride cells were vacuolated. Fish were able to withstand these changes in subacute experiments due to redundancy in gill surface area.
