“…Combination of peeling process and without washing increased the removal efficiency of residues to 96.98, 96.07, 95.50 and 98.32% loss of pirimiphos-methyl, malathion, fenitrothion and fenpropathrin, respectively. Also our results were in harmony with those of Powell et al (1970), Zidan et al (1991), Ramadan (1991) and Ismail et al (1993).…”

Different pesticide residues (carbofuran, carbosulfan, methomyl, malation, silycron and cypermethrin) were extracted from treated samples of tomatoes fruits and potatoes tubers before and after food processing. GLC, spectrophotometric and enzymatic methods were used to determine pesticide residues in different samples. Pesticide residues for all pesticides were detected with the previous methods with some variation in results depending on the methods sensitivity. The pesticide residues concentration in potatoes tubers were ranged between 8.74 and 7.24 ppm for cypermethrin and malathion with using spectrophotometric methods, while these residues concentrations were ranged between 8.407 and 7.79 ppm for carbofuran and malathion by using enzymatic methods. Silycron residues was 8.3 ppm with using GLC. Also the same parameters was used with tomatoes fruits. The detected concentrations for malathion was ranged between 8.22 and 0.534 ppm with used spectrophotometric methods before and after food processing. The detected pesticide residues of methomyl and malathion were used to determine their effects on some enzymes activities (in vivo).Results showed that all concentrations were affected gradually on the alanine amino transaminase (ALT), aspartate amino transaminase (AST), acid phosphatase, alkaline phosphatase and acetyle cholinestrase (AchE) activities.

“…In the 1970s, when the registration of dieldrin and aldrin treatment was enforced, it was reported that dieldrin penetrates carrot, soybean, peanut, potato, radish, rye and tomato plants [2][3][4][5][6][7][8][9][10][11][12][13] ; however, dieldrin residues in cucumber fruits are the most remarkable, and are thus a serious problem (Figs. 1-2).…”

Dieldrin uptake by cucumber fruits was examined using a variety of cucumber scions and squash rootstocks. The effect of activated carbon on reducing uptake was also determined. Three varieties of cucumber (Cucumis sativus L.; Sharp 1, Natsusuzumi and Nankyoku 2) and three varieties of squash (Cucurbita spp.; Kirameki, Yuyuikkiblack and Shintosa) were used. There was no significant difference in dieldrin uptake between cucumber scion varieties. The order of uptake between the varieties of rootstock was ShintosaϾYuyuikki-blackϾKiramekiϭself-rooted plants. In the case of Shintosa, a change to Kirameki or self-rooted plants reduced the dieldrin concentration to 53-34%, treatment of soil with activated carbon to 57%, and the combination of changing the rootstock to Kirameki with activated carbon to 16%. In the case of Kirameki, treatment of soil with activated carbon reduced the dieldrin concentration in cucumber fruits to 42%. In the case of self-rooted plants, a change to grafting culture with Kirameki rootstock and treatment of soil with activated carbon was effective in reducing dieldrin concentration.

“…Powell and coworkers (315) studied the effects of commercial processing on residues of aldrin and dieldrin in tomatoes and residues in subsequent crops grown on the treated plots. Aldrin and dieldrin residues were determined after acetonitrile extraction and cleanup on a Darco G-60 Solka Floe column.…”
