大気汚染は心臓病に繋がる

Air pollution link to heart disease

 Researchers reported a link yesterday between long-term air pollution and the early stages of artery disease in people long before they showed obvious symptoms.
 They suggested tiny particles of pollutants from fossil fuels used in motor vehicles and industrial processes such as smelting and processing metals were triggering inflammatory reactions in the respiratory system and blood vessels; and that this began a long process that leads to a hardening of the arteries, then heart disease and strokes.

 研究者たちは、昨日、長期にわたる大気汚染と明らかな兆候を示すずっと以前の人々の動脈硬化の初期の段階との関係を報告した。
 彼らは、自動車や金属を融解したり加工処理したりする産業工程で用いられる化石燃料の微小な汚染粒子が呼吸器系や血管の炎症性反応を引き起こし、しかもこのことは動脈硬化、さらに心臓疾患や心臓発作に繋がる長い過程の始まりであることを示した。
