吃飯,別在桌上墊報紙

文章snakehsu » 週四 2月 08, 2007 9:06 pm


用報紙當桌布,聽著似乎有不少好處,但事實究竟如何?

吃飯時不能用報紙墊桌子,更不建議用印刷物直接接觸食物,否則很可能導致油墨污染。

報紙油墨含毒多

油墨中的主要污染物是重金屬,包括鉛、鉻、鎘、汞等,它們都可能對人體產生一定危害。

比如,鉛元素不僅會阻礙人體血細胞的形成,還能通過血液進入腦組織,造成腦損傷。當體內的鉛積累到一定程度時,就會出現精神障礙、噩夢、失眠、頭痛等慢性中毒症狀。

此外,報紙印刷時使用的油墨通常含有乙醇、異丙醇、甲苯、二甲苯等具有毒性的有機溶劑。雖然這些有機溶劑幹燥後,絕大部分危害會消除,但殘留部分仍然會對人體形成潛在危險。

特別是報紙彩頁,油墨面積大、墨層厚,有機溶劑的殘留會比較多。如果長期吸入,可能影響到大腦的中樞神經,對健康造成極大危害。

有機溶劑的危害會比較明顯地體現在新報紙上,所以決不能用新報紙墊桌子。

如果只能用報紙墊,就一定要避免手或餐具接觸報紙,以將潛在危害降到最低
