物分解性廃棄物」の2種類に分けて排出するよう依頼した。フエ市では透明な3種類の色のごみ袋を配布し，「生物分解性廃棄物」，「非生物分解性廃棄物」，「資源化物」の3種類に分けて排出するよう依頼した。調査世帯には毎日訪問し，生物分解性廃棄物については対象世帯で毎日分類・計量した。一方，非生物分解性廃棄物・資源化物については，カントー市の第1回調査（乾期），フエ市の調査では1週間ごと，カントー市の第2回調査（雨期）では毎日，調査世帯から研究室に持ち帰って分類・計量した。

ごみ組成の分析に当たっては，Tanikawa $ ^{10)} $ ，Ojeda-Benitez et al. $ ^{11)} $ ，Burnley et al. $ ^{12)} $ ，Kawai $ ^{13)} $ ，Dahle'n and Lagerkvist $ ^{14)} $ ，Gomez et al. $ ^{15)} $ といった先行研究を参照し，カントー市の調査では物理組成10区分，用途・形状別83区分のごみ細組成分類表（表4.4.3）を作成し，これに従って分類した。フエ市の調査ではインフォーマルセクターにおける資源化物の分類区分に従ってさらに組成を細分化し，第1回調査では90区分，第2回調査では135区分のごみ細組成分類表を作成し，これに従って分類した。計量に当たってはタニタ製のデジタルキッチンスケールを用い，世帯別・細組成別に1g単位（湿重量）で計量・記録した。また，対象世帯に対して個人属性，資源化物の排出先等についての面接調査を併せて実施した。

##### 4.4.2.4 解析手法

各世帯の対象期間の総排出量を排出日数・家族人数で除して排出原単位（g/人/日）を算出し，物理組成別・細組成別の排出原単位の基本統計量を求めた。また，これらの排出原単位と個人属性等の要因との関連性について，一元配置分散分析・順位相関分析により検討し，主要物理組成の発生率について，これら関連要因を用いた線形回帰分析を行った。全ての統計解析は，SPSS ver. 15.0 を用いて実施した。
