| A determination method of carbendazim (MBC), thiophanate-methyl (TM), and benomyl (BM) in agricultural products by using HPLC was investigated. MBC, TM and BM were extracted with methanol from homogenates of agricultural products. The methanol extract was evaporated down to ca. 70 mL, and 100 mL of 10% sodium chloride solution added, and defatted by n-hexane partitioning. The three compounds were extracted with ethyl acetate- n-hexane (1:1) from the aqueous layer and adjusted to pH 6 - 7. BM was hydrolyzed to MBC while being extracted with methanol. TM in the ethyl acetate - n-hexane (1:1) extract was converted to MBC by refluxing at 120°, for 30 min with copper acetate in 50% acetic acid. For tea samples, the three compounds were cleaned up using Bond Elut® PSA after refluxing with copper acetate. Total concentration of BM, TM and MBC were measured as that of MBC by HPLC. Recoveries at the 0.10 µg/g level were more than 70% from agricultural products except for some crops. The detection limits were 0.01 µg/g in all samples, except for tea where the limit was 0.05 µg/g. |

| Kusaya is a traditional marine product processed by drying fishes such as "Muroaji" (Scad) and "Tobiuo" (Fly fish) after soaking in fermented brine. Kusaya has been made exclusively in the Izu-Islands, in the Tokyo district of Japan. Recently a new semi-dried product of one, called "Soft-type", has been put on the market and has been accepted favorably by consumers. Utsubo (Moray eel) is one of the popular fishes caught around the Izu-Islands, and served raw or as himono (dried products). The consumption of these fish products is increasing, not only in the local area but also in urban areas, while their nutritional data, except conventional Muroaji-Kusaya, is not found in the only integrated nutritional data book, "Standard tables of food composition in Japan". Under these conditions, for the sake of consumers and producers convenience, a determination of the macro components and minerals in "Soft-type" (Muroaji-Kusaya), Tobiuo-Kusaya, and Utsubo (raw, himono) was made. The nutrient values of "Soft-type" (Muroaji-Kusaya) were found to be 56.6 g water, 35.5 g protein, 4.6 g fat, 0.2 g carbohydrate, 3.1 g ash, 995 mg sodium, 81 mg calcium, and 2.5 mg iron. Tobiuo-Kusaya contained 59.8 g water, 35.1 g protein, 0.4 g fat, 0.2 g carbohydrate, 4.4 g ash, 717 mg sodium, 148 mg calcium, and 0.5 mg iron. Utsubo (raw) contained 77.5 g water, 18.4 g protein, 1.5 g fat, 1.0 g carbohydrate, 1.6 g ash, and 87 mg sodium. In Utsubo (himono) there was shown to be 55.2 g water, 27.4 g protein, 10.6 g fat, 2.3 g carbohydrate, 4.9 g ash, and 882 mg sodium. (All values are expressed as amounts per 100 g edible portions.) |

| Pesticide residues in 66 samples of 19 species of domestic vegetables and fruits, obtained from the Tokyo marketin fiscal year 2004, were investigated. Five kinds of pesticides were detected in 9 samples of 8 species of domestic vegetables (detection rate: 17.6%). Their concentrations were between trace (0.005 - 0.01 ppm) and 1.74 ppm. Fifteen kinds of pesticides were detected in 12 samples of 5 species of domestic fruits (detection rate: 80.0%). Their concentrations were between trace and 1.77 ppm. Residues of these pesticides were at the levels lower than Japanese MRLs. |

| Organophosphorus and organonitrogen pesticide residues in 259 imported crops, obtained from the Tokyo market in fiscal year 2004 were investigated. In twenty five species of crops, residues of 15 organophosphorus insecticides, 8 organonitrogen fungicides, and 1 organonitrogen insecticide were detected. Concentrations of organophosphorus insecticides (methamidophos, chlorpyrifos, triazophos, etc.), organonitrogen fungicides (triadimenol, triflumizole, myclobutanil, etc.), and organonitrogen insecticides (buprofezin) were between trace (0.005 - 0.01 ppm) and 0.33 ppm in 51 crops, and trace and 0.18 ppm in 16 crops, and 0.04 ppm in 1 crop, respectively. Nineteen of the pesticides detected in 21 species of crops are regulated by the maximum residue limits (MRLs) of Japan. Methamidophos in 3 samples of litchi produced in China and Thailand exceeded the MRLs of Japan. |

| Pesticide residues in 259 imported crops were investigated from April 2004 to March 2005. Residues of organochlorine pesticides, 3 kinds of insecticides (total-BHC, Dicofol, and total-Endosulfan), and 5 kinds of fungicides (Captan, Chlorothalonil, Iprodione, Procymidone, and Vinclozolin) were detected in 14 species of 24 crops between trace (0.005 - 0.01 ppm) and 0.64 ppm. Amongst N-methyl carbamate pesticides, one kind of insecticide (Carbaryl) was detected in 2 species of 3 crops between 0.13 and 0.22 ppm. From the pyrethroid pesticide group, 6 kinds of insecticides (Bifenthrin, Cyhalothrin, Cypermethrin, Fenpropathrin, Fenvalerate, and Permethrin) were detected in 12 species of 21 crops between trace and 0.46 ppm. In the others, 3 kinds of fungicides (Imazalil, o-Phenylphenol, and Thiabendazole), one kind of herbicide (2,4-D), and one kind of insecticide (Piperonyl butoxide) were detected in 8 species of 30 crops between trace and 6.6 ppm. Residues of these pesticides were at the levels lower than the maximum residue limits (MRLs) of Japan,the MRLs of the each country, and the Codex MRLs for pesticides. |

| 35 Survey of Bromine Residues in Imported Agricultural Products
|
| Yumiko YAMAKI, Tsuneo HASHIMOTO, Takeo SASAMOTO and Akihiro IBE |
| Bromine residues in imported agricultural products were analysed by GC-ECD. One hundred and eighty-three samples (fruits, grains, nuts, and hops) were purchased at retail stores in Tokyo between April 2003 and March 2005. Fifty-five samples contained bromine in the range of one to 22 ppm. All bromine residues in fruits and grain samples were below the maximum residue limits (MRLs) as specified in the Japanese Food Sanitation Law. The residues in other agricultural products with no MRLs were below the levels based on the final draft of provisional MRLs in food toward the introduction of the Japanese "Positive List" system. |

| Dioxins, which include polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and coplanar polychlorinated biphenyls (Co-PCBs) were analyzed in imported farmed and wild salmon. The residue levels of dioxins in farmed salmon were 0.38 - 5.2 pg TEQ/g wet weight, but in wild salmon the level was 0.95 pg TEQ/g wet weight. In each sample, the residue level was less than the tolerable daily intake (TDI) at usual intake levels. The major exposure path of farmed salmon to dioxins was possibly thought to be thought their feed. The contribution ratio of Co-PCBs to dioxins was much greater than that of PCDDs or PCDFs, and these were thought to originate from PCB-containing materials. |

| 38 Dietary Daily Intake of Nonylphenol in Metropolitan Tokyo Area
|
| Akiko YASUI, Mitsuo OISHI, Fusako ISHIKAWA, Tetsuya SHINDO, Masao HORIE and Koichi ITO |
| Studies of the daily intake of Nonylphenol (NP) through foods obtained in the Tokyo metropolitan area were carried out from 2002 to 2004, by the total diet-market basket method. In adult foods, The daily intake of NP was estimated to be 74 ng/kgbw/day in 2002 and 67 ng/kgbw/day in 2003, respectively. NP was below the detectable limit in 2004(ND<5 ng/g). In infant foods, studied in parallel with adult foods in 2002, the daily intake of NP was estimated to be 140 ng/kgbw/day. Detectable NP was not observed in the study of baby food in 2003 and the study of "the meal including take-away foods" in 2004. These studies indicate that the amount of NP intake contributed by food is very low. |

| 39 Hygienic Chemicals Studies on Organotin Compounds Content of Tributyltin and Triphenyltin Compounds in Fish and Shellfish, 2002 - 2004
|
| Kazuko MIZUISHI, Yasushi ONO and Shuzo OGINO |
| A survey of tributyltin (TBT) and triphenyltin (TPT) compounds in fish and shellfish was performed from 2002 to 2004. The fish and shellfish, 480, were purchased from the Tokyo central market and consisted of groups: A) cultured fish and shellfish, B) bay or inshore fish and shellfish, C) offshore fish, and D) imported fish and shellfish. The annual averages of TBT in the samples were 0.007 ppm in 2002, 0.008 ppm in 2003, and 0.005 ppm in 2004, respectively, and the annual averages of TPT were 0.004ppm in 2002, 2003, and 2004. The over all averages of the three years for TBT and TPT were 0.007 ppm and 0.004 ppm, respectively. Both values were almost 40% lower than the averages from the previous investigation of TBT and TPT in fish and shellfish, performed during 1999 - 2001. A law banning the production and use of TBT and TPT has been in force since 1991 in Japan. It was evident that, following the restriction on the production and use of TBT and TPT in 1991, their levels in fish and shellfish had decreased, drastically at first stage and then gradually afterwards. These decreases may reflect the banning of TBT and TPT use in marine environments in Japan. |
