“…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.

“…It was found that dieldrin readily remained in vegetables in the 1960s. 4,9,10,[20][21][22][23][24][25] In this study, we obtained levels of drins residue in cucumbers. Dieldrin residue over the tolerance (0.02 ppm) was detected in 12 samples, which is 3.6% of 330 cucumbers produced in Tokyo.…”

Soil samples were obtained from 814 farms in Tokyo in 2002. Dieldrin residue was detected in 85 soil samples at concentrations ranging from 0.01 ppm to 2.6 ppm. The residual amount in 70% of dieldrin-positive samples was 0.1 ppm or less. Concentrations of dieldrin residue in cucumbers cultivated in Tokyo exceeded the tolerable level (0.02 ppm) and ranged from 0.02 ppm to 0.1 ppm in 12 of 330 samples. The horizontal distribution of dieldrin in fields was not uniform and the range varied from the quantitative limit (0.01 ppm) to 0.73 ppm. The vertical distribution of dieldrin was also inconsistent. With deeply plowed fields, the vertical distribution was from the surface to a depth of 70 cm, although dieldrin was detected at 30 cm in fields that had not been plowed. As the cucumber roots grew about 1 m in the horizontal and vertical directions, we need to analyze soil samples to a depth of 1 m to prevent dieldrin residue from contaminating cucumbers.
