回南天牆身天花出水起霉菌!K Kwong教一招清走有毒霉菌

踏入春天本港又開始潮濕,近幾日相對濕度高達95%,早前更有不少市民家中牆壁及天花嚴重出水,令人困擾。回南天濕氣重易起霉菌,化學博士K Kwong近日在Facebook發文,教授一招對付霉菌,建議市民一有發現就出手清潔,避免霉菌繁殖影響健康。

甫轉春季濕度上升,牆壁及天花就會出現大量水珠,嚴重的地區甚至會演變成「水簾洞」,水珠滴不停。濕氣易滋生霉菌,霉菌難清理又會危害健康,不少市民束手無策,十分苦惱。化學博士K Kwong提醒,室內黴菌 (牆霉菌)是香港常見的室內微生物,「喺潮濕、溫暖嘅環境(例如廁所浴室、廚房、冇見窗嘅房)生長。佢嘅霉孢子係空氣飄浮,一黐到有水嘅地方就可以生長。長大後菌絲會變成黑色。」

霉菌有機會導致過敏反應、呼吸道感染、哮喘病人症狀惡化等問題,此外,由於部分霉菌產生的代謝物有毒,長期吸入有可能導致免疫功能、神經系統、器官功能障礙,所以如有發現就要清除。

K Kwong教路一發現霉菌就要立即用1:49漂白水抹上,行動要快,避免霉菌孢子深入牆壁。另外,抹牆時要戴口罩及保持室內通風。如果嫌漂白水味太刺激,可以選用彩漂水(一匙羹開~500mL)。他補充指:「霉菌D蛋白質一黐到漂白水、彩漂水就立即被毀滅。而黑色菌絲亦可以俾漂白水氧化而變成淡色」若發現出完黑色霉之後有敏感,如身痕和鼻敏感,市民可考慮用有 HEPA 濾芯的空氣清新機。

若市民家中採用假天花,K Kwong博士提醒最穩陣用水抹,「如果係金屬用漂白水會腐蝕。」另外,用漂白水抹完後無需要再過清水一次。霉菌滋生速度快,博士強調若有發現一定要盡早處理,越遲抹只會更難搞。同時,博士補充用酒精無法代替漂白水作用,有需要市民記得留意!
