In the dioxins database, the samples of 54 exhaust gases, 167 ambient airs, 213 soils, 121 sediments and 140 river waters were used. Those samples were collected in Fukuoka, Japan from 2000 to 2004. The dioxins database consists of a total of 126 parameters, including isomer concentrations (116 parameters) and congener concentrations (10 parameters). The TEQ indicators were decided from correlation between isomer concentrations (116 parameters) and TEQ in each medium. Consequently, it was confirmed that 2,3,4,7,8-PeCDF in exhaust gas and ambient air, 2,3,4,6,7,8-HxCDF in soil, 1,2,3,4,8/1,2,3,7,8-PeCDF in sediment, and 1,2,3,6,7,8-HxCDD in river water are available as TEQ indicators.

Analysis of Yohimbine Hydrochloride in Health Foods by HPLC
Kunimasa MORITA, Takami MOHRI, Reiko NAKAGAWA Fukuoka Institute of Health and Environmental Sciences, Mukaizano 39, Dazaifu, Fukuoka 818-0135, Japan A reverse-phase HPLC method for determining yohimbine hydrochloride in health foods is described. Yohimbine hydrochloride in health foods was extracted with 0.1% acetic acid in methanol. The sample solution for HPLC was applied to Bond Elut Certify (solid phase extractions) with 2% ammonium hydroxide in methanol as the mobile phase. HPLC analysis was (4.6 x 150 mm, 5 microns) with 0.02 mol/L phosphate buffer pH 7.0 carried out on a column of Cosmosil 5C18-MS- /acetonitrile (65:35, v/v) as the mobile phase and the eluate was monitored by UV detection at 276 nm. The average recovery of yohimbine hydrochloride from health food was 99.5%. The quantitation limit of this method was 0.03mg/g.

Flavonoids dissolve into water in the manufacturing process and outflows may reach the drinking water. Using 15 commercial Flavonoid standards, their solubility and THMFP were examined. Flavonoid solubility as DOC of 30 to 40mg/l under saturated solubility at 20 were  Fisetin, Flavanone, Hesperetin and Fustin. Morin, the highest THMFP value by DOC was between 300 and 400 °g/mgC . Calculating from solubility and THMFP value by DOC ,  higher THMFP values under saturation were shown by Naringenin   Hesperetin and Quercetin. It was assumed that Flavonoids such as Naringenin etc. would have to be diluted about 10000-fold when estimated under the influence of less than 1 °g/l of THM.

2 · 4 評価
BOD, T-N, T-Pの各測定項目は濃度範囲がそれぞれに異なっているため，回帰係数の値も範囲がそれぞれ異なっていた．各項目間の比較を容易にするために，回帰保数（a）の標準化を行った。標準化は回帰係数（a）を平均水質値で除することで行い，インデックス値とした.またN/P比は無次元の値であるが，平均値を使用し他の項目と同様に取り扱い，インデックス値を求めた．下記に計算式を示す.インデックス値＝（回帰係数/平均水質値(BOD, T-N, T-P)又は平均値(N/P比)）×100このインデックス値は，平均水質値に対する１年あたりの変化量（回帰係数（a)）の相当パーセントを表している。また，各調査地点は表1に示す流域に分類し，それぞれの流域，各水質項目のインデックス値について平均値を計算し，インデックス値の頻度分布についてはヒストグラムを作成した.
3　結果および考察
3  : 11  インデックス値及びその頻度分布
県内全河川及び流域毎に計算したインデックス値の平均値を各項目毎に表1に示す。また頻度分布は，県内全河川の計算結果について図１から図３に示す。他の流域のインデックス値の頻度分布は省略する。また，各結果の考察については，以降に述べる．

3 : 2  県内全河川
BODのインデックス平均値は1.2%／年の減少傾向を示していた．BODのインデックス値の頻度分布は（−2≤X < 0）にピークを示し，全地点の29%であった．減少傾向を示す地点は全地点の63%を占めており，県内の多くの地点ではBODは減少傾向にあると考えられる. T-Nのインデックス平均値は0.36%／年のわずかな増加傾向であり，県内の多くの地点でT-Nは増加傾向にあると考えられる. T-Nのインデックス価の頻度分布は，増加傾向を示す（0≤X＜2）にピークを示し，全地点の50%であった．また（2 ≤ X ＜4）の大幅な増加傾向を示す地点も18%あり,増加傾向を示す地点は全地点の69%を占め, T-Nは増加傾向にあると考えられる. T-Pのインデックス平均値は0. 16%／年であり，T-Nのインデックス平均値と比較し増加の傾向は小さく，変化が少なかった。T-Pのインデックス値の頻度分布は，微少な増加傾向を示す(0≤X＜2)の階級にピークを示し,全体の27%を占めていた。また，(0 ≤ X ≤ 2)の階級に属する地点と（−2≤X≤0）の階級に属する微少な減少を示才地点は全体の約49%を占めていた.これらのことから県内の河川の全体的な傾向は，BODは減少傾向にあり，T-Nはわずかな増加傾向を示し，T-Pは変化が少なかった。

The findings showed that rivers in each area classified into 4 typical groups (urban area,  city and surrounding commuter towns,  developing rural areas and coal-bearing areas in the past) by the combination of trends in water pollutions. The concentration of T-N and T-P was increasing even in areas where wastewater treatments had spread. Therefore, further spread of advanced wastewater treatments needs to be promoted in this area. Especially, the concentrarion of T-N was incresing in almost all area in Fukuoka prefcture and breaking the balance of water quality such as N/P ratio.

2・3　分類・同定
夾雑物とともに落下した土壌動物群から実体顕微鏡下でトビムシ類を拾い出し，ガムクロラール封入剤を用いプレパラート標本にし,生物顕微鏡下で同定,計数した.なお，同定は青木淳一編著日本産士嬢動物"に従い属まで分類・同定した。
３　結果及び考察
採集結果を，付表1-1－1-2に示す。なお，付表には資料として記録しておく意味で各林分の各調査月毎の採集結果を記載しているが，本報告では里山のトビムシ相の概要を知るため全期間を通した採集結果について述べv.全期間を通して52属12444個体が採集され，最も個体数が多かったトビムシは，フォルソムトビムシ属Folsomia (4705個体，全採集個体数に対する割合：37.8 %）で，次いでシロトビムシ属Onychiurus (1960個体,同15.8%),ヒメフォルソムトビムシ属Folsomina (1166個体，同9.4%）が多く，全期間を通して見た場合，これらのいずれかがすべての林分で最優占種であった。上記以外に多かったトビムシ類は，メナシツチトビムシ属Isotomiella (694個体,同5.6%),トゲトビムシ属Tomocerus (554個体，同4.6%),ホンシロトピムシ属Tullbergia (513個体,同4.1%),ムラサキトビムシ属Hypogastrura (500個体，同4.0%)であった．また，アヤトピムシ科Entomobryidaeに属するトピムシが二次林であるNo. 2からNo. 7の林分に多く見られた.各林分でのトビムシ類の個体数は図1に示すように, No. 2ツブラジイ林で最多(3160個体)であり,次いで, No. 3コナラ林(1631個体), No. 4コナラ林(1242個体), No. 11ヒノキ林(1075個体), No.7アカマツ林(1060個体)で多かった．逆に個体数が少なかったのは，No. 8クスギ林（259個体）, No.9スギ林（327個体）, No.10ヒノキ林（393個体）, No. 12マダケ林（505個体）であった.このように個体数の各林分間の変動係数値が0.76と大きいことからも示唆されるように林分によって個体数は極端に変動していた。また，表1に示す地形の斜面上部に位置する林分では個体数が多く，斜面下部に位置する林分では少ない傾向が，また，相親植生の二次林の林分では個体数が多い傾向が伺えた。各林分でのトビムシ類の属数は図2に示すように，No. 3コナラ林（36属）, No. 9スギ林（34属）, No. 2ツプラジイ林（33属）, No.7アカマツ林（33属）, No.6アカメガシワ林（32属）で多かった。一方，No. 8クヌギ林（2 1属), No. 5ハゼノキ林(25属), No. 10 ヒノキ林(25属), No. 12マダケ林（25属）で少なかった．各林分間の属数の変動保教値は0.16と小さく，属教は個体数に比べ林分間で大きな差はないものと言える。また，個体数で見られたような地形，相親梳生との間に明瞭な傾向は見られたかった.トピムシの各林分間の属模成の類似性（Jaccardの共通係数）に，No. 1ツブラジイ林，No. 8クヌギ林及びNo. 10ヒノキ林のそれぞれと他の林分間では，相対的に低い共通係数値を示す場合が多かった．すなわち，No. 1ツプラジ2 3 1 12 No. 8
