飲用水

作者:水商網
飲用水含義:

飲用水是具有一定品質管控,可供飲用或使用而不會立即造成或長期性危害的水。在多數發達國家,也只有極低比例的水實際使用于飲用或烹飪,常見用途包括洗滌和景觀灌溉等,但其家庭、商業和工業用水皆已達飲用水標準。

水是人體的重要組成部分,也是新陳代謝的必要媒介。人體每天消耗的水分中,約有一半需要直接喝飲用水來補充,其他部分從飯食中直接獲得,少部分由體內的碳水化合物分解而來。成人每天至少需要補充水分1200毫升左右。運動量大的人,需1800~2400cc。

在世界大部分地區,人類未獲得足夠的飲用水取水途徑,使用水來源亦多半受到病媒、病原或過量毒素或懸浮物的污染,不利于人體健康。一旦人類飲用或食用這種受污染的水體,將造成大規模的急性或慢性疾病,這是許多國家的主要死因。降低水傳染病發生率是現今發展中國家的重要公共衛生目標。

飲用水組成成分:

(1)微量礦物;(2)亞硝酸鹽;
