本研究の目的は、近年経済発展が著しいベトナムの首都ハノイおよびその近郊を対象に、現地研究者との共同研究を通じて電気・電子機器廃棄物(e-waste)やプラスチック廃棄物(PW)、そして使用済み自動車(End-of-Life Vehicles: ELV)に含まれる難燃剤、可塑剤、紫外線吸収剤、酸化防止剤などの有害化学物質、そして生活・工業排水に混入している医薬品・日用品関連化学物質(PPCPs)を対象に、環境汚染の実態と生物蓄積、そしてリスクを究明することにある。さらに、PW処理施設では排水と近隣河川におけるマイクロプラスチック(MP)汚染の実態と、MPに含有もしくは吸着する内分泌かく乱性化学物質の探索・同定を試みる。初年度は、愛媛大学沿岸環境科学研究センターの生物環境試料バンク（es-BANK）に冷凍保存されていたベトナムの環境試料を用いて、難燃剤や可塑剤として使用されるリン酸エステル系難燃剤(PFRs)と新規残留性有機汚染物質(POPs)の短鎖塩素化パラフィン(SCCP)、コーティング剤等に使用されている有機フッ素化合物(PFAS)、プラスチック原料や酸化防止剤として使用されるビスフェノール類、ベンゾフェノンおよびベンゾトリアゾール系紫外線吸収剤の分析法開発を進めた。現在、標準品を用いたガスクロマトグラフ（タンデム）質量分析計(GC-MS[/MS])、液体クロマトグラフタンデム質量分析計(LC-MS/MS)、液体クロマトグラフ四重極飛行時間型質量分析計(LC-QTOFMS)の測定条件の最適化は完了している。また、プラスチック添加剤の溶出試験から核内受容体のアゴニスト・アンタゴニスト活性を測定するためのin vitroバイオアッセイ法の構築に着手した。

The purpose of this study, in recent years, is to conduct a joint study on the general purpose of this study. The purpose of this study is to conduct an exhibition in recent years. In recent years, in recent years, the purpose of this study is to jointly study the general purpose of this study, the purpose of this study, the recent years' exhibition in recent years, and the purpose of this study, in recent years, in recent years, the purpose of this study is to conduct a joint study on the general purpose of this study, the purpose of this study, in recent years, in recent years, the purpose of this study, in recent years, has been held in recent years. The purpose of this study is to conduct a joint study of the general purpose of this study, the purpose of this study, in recent years, in recent years, the purpose of this study is to study the electrical equipment in the suburbs of the capital, the suburbs, and the local researchers to jointly study the electrical equipment of general Acidizing prevents hazardous chemicals, domestic and industrial drains from mixing with waste water, medical supplies, daily necessities, chemical substances (PPCPs), environmental pollution, ecological biological storage, environmental pollution, environmental pollution and environmental pollution. In the construction of PW, the drainage system is close to the river, and the MP contains the same concentration of endocrine absorption, endocrine absorption, disordered chemicals, and so on. Environmental Science Research in the Coastal area of Taiyuan University in the first year of the year, the Coastal Environmental Research Institute of Taiyuan University (es-BANK) has been used in cold storage for the use of waste materials for the environment, and for the use of fuel-burning plastic materials. The use of thermal acid is based on the new regulation residue of the fuel engine (PFRs), the organic residue dye (POPs), the short-term organic dye (SCCP), and so on. For example, the use of organic compounds (PFAS), acidification of raw materials to prevent the use of chemical compounds, such as organic compounds, chemical compounds, etc., to prevent the use of chemical compounds, such as organic compounds, chemical compounds, etc., to prevent the use of chemical compounds, such as organic compounds, chemical compounds, chemical compounds, organic compounds At present, the standard products use GC- MS [/ MS], LC-MS/MS and LC-QTOFMS to optimize the measurement conditions. The drug was dissolved in the nuclear capacitor. The activity was measured by the in vitro method.
