Evaluating the Endocrine‐Disrupting and Oxidative Stress Potential of a 50‐Component Human‐Relevant Complex Chemical Mixture Using In Vitro Tests

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Humans are chronically exposed to mixtures of environmental contaminants. Exposure to endocrine‐disrupting chemicals (EDCs) contributes to increased health impairment observed globally. This study aimed to evaluate the endocrine‐disruptive and oxidative stress potential of a human‐relevant, complex chemical mixture in vitro.

Eicosapentaenoic and Docosahexaenoic Acid Levels in Mouse Tissues After Intake of Echium and Ahiflower Oils Rich in Stearidonic and α‐Linolenic Acids

open access: yesLipids, EarlyView.
Dietary supplementation with stearidonic acid–rich Echium and Ahiflower oils increases EPA levels across multiple mouse tissues, while DHA responses remain tissue‐specific and limited, supporting the strategic use of plant‐based omega‐3 sources for EPA‐focused interventions. ABSTRACT Omega‐3 fatty acids (n‐3 FA), particularly eicosapentaenoic acid (EPA)

Dioxins Problem. Achieving Zero Dioxin.

open access: yesWaste Management Research, 1997
ダイオキシン汚染は, 今すぐにそれをなくすための対策をとらなければ手後れになるという深刻な事態にまで進んでいる。低レベルのダイオキシンが生体に及ぼす多様かっ微妙な影響が人の健康や生態系, 次世代や種の存続を脅かしている。そうした影響は従来のリスクアセスメントで正確に測り知ることはできない。ダイオキシンの発生に共通する要因は塩素およびその化合物である。が, 未確認あるいは情報の限られている発生源もあり, 未だダイオキシンの発生量はほとんど不明である。世界はダイオキシン等のPOPsを削減/撤廃するため, 地球規模の法的拘束力を持つ条約策定に向けて動き出した。その成功を期すために日本政府の責務も重大である。日本政府は, 人の健康や環境には許容できるダイオキシンのレベルはないという認識のもと ...
