家居甲醛5大元兇中夾板製傢俬最高??


去除甲醛,首先要找出元兇。TOPick訪問了尚譽環境安全科技的環境安全工程師劉先生(占sir),綜合出家居常見的甲醛5大元兇:

1.      傢俬:衣櫃、沙發、書架
使用夾板、人造木板製作的傢俬,是家居甲醛的最大元兇。他解釋,夾板、人造木板在製作過程中使用了油溶性膠水,而這種膠水正含有甲醛
許多傢俬如鞋櫃、床、茶几等,都由夾板裝合而成,加上夾板有一定厚度,甲醛會慢慢持續滲出來,釋放期較長。

2.      油漆:水晶蠟、光油
油漆都是甲醛的元兇之一,但相比夾板,家居裝修時的油漆塗層通常較薄,因此甲醛釋放期較短。

3.      防水物料
不少業主裝修家居時,為了減少漏水或滲透的可能性,會添加防水物料做成防水層,特別是廚房及廁所的瓷磚地下,防水物料也會釋放甲醛,影響健康。

4.      小孩專用的防撞軟膠墊

5.      黏地氈的膠水
黏地氈時所用的是油溶性膠水,故含有甲醛。不少港人都愛黏牆紙裝飾家居,占sir卻指,用來的黏牆紙的膠水屬於水溶性膠水,不是甲醛釋放的元兇。

sir更強調,溫度和濕度愈高,甲醛揮發得愈快,因此夏季的是相對高危的季節。

用光觸媒除甲醛是否最安全???


中國工程院院士鍾南山早前引用中國環境保護協會資料,指90%白血病兒童患者的家中,曾進行豪華裝修,即每年約有210萬名白血病兒童死於此因;80%的家庭裝修後,甲醛仍超標;70%孕婦流產和環境污染有關。而內地每年因室內環境污染引起的死亡人數更高達11.1萬人。他說,室內環境污染已成現代人健康殺手之一。

據《晴報》報道,浸會醫院臨床腫瘤科顧問醫生梁廣泉表示,室內裝修是誘發癌症的原因之一,若長期吸入甲醛、天拿水,是加大患癌的機會,而食物、環境、污水,及無色、無味、無臭的放射性氣體氡氣等都會影響健康

但本港較少會追查兒童患癌原因或類似的研究,若必需要裝修,應事隔23星期才入住,兒童、孕婦亦須注意。
                                                                                              
事實上,不只新居有甲醛問題,傢俬如衣櫃、沙發、書架、油漆,甚至小孩專用的防撞軟膠墊都會持續釋放致癌甲醛,實在是防不勝防。

吸入甲醛對身體有何影響?
急症科醫生梁啟城指,甲醛具刺激性,吸入少量會刺激眼和鼻,導致流眼水、鼻水,長期吸入則會導致慢性中毒,對肝、肺、腎傷害最大,嚴重情況可致癌。

甲醛對孕婦名初生嬰的傷害最大,前者吸入可致流產或畸胎,後者則會導致心、腦發育不健全。

根據世衞轄下的國際癌症研究所(International Agency for Research on Cancer, IARC),甲醛(formaldehyde)是1級致癌物。引述世衛資料關於中國內地統計,連續46個月,每天在高濃度甲醛(0.40.5ppm)室內空間停留812小時,會增加血癌風險。

不少人會將水果如菠蘿切開,其實水果只能吸味道,無助於去除甲醛。而部分植物如虎尾蘭,及活性碳的確有吸收甲醛之效但始終數棵植物、一點活性碳對全屋的甲醛效用有限。

TOPick訪問了尚譽環境安全科技的環境安全工程師劉先生(占sir),教你選擇高品質除甲醛產品。

除了家裡必須要時刻保持通風,亦可進行光觸媒、空氣觸媒等分解甲醛工程。以占sir公司為例,500呎單位:基本光觸媒除甲醛工程費用約2000元;中等3000元;最貴則為6000元。1000呎單位:基本費用約3000元;中等7000元;最貴則為15,000元。

想經濟一點,亦可在市面上購買空氣或光觸媒自行噴灑

何謂高品質真貨?產地最重要
光觸媒的主要成分為二氧化鈦(TiO2空氣觸媒則為TiO3。在國內見過有冒充的光觸媒,成份其實是氧化劑,只能即時分解當刻的甲醛,效果很短暫;反觀真正光觸媒,分解的甲醛可持續約57年。

TiO2TiO3本來對人體無毒無害不過要使粉狀的光觸媒或空氣觸媒黏附物件表面,就須加入黏合劑,而部分黏合劑可會造成「二次污染」,意思是以另一種未通過安全測試的化學物質去處理原本的有毒物質,安全成疑

日本出產光觸媒噴劑最有保證!寫『日本技術,台灣製造』的都不算,一定要『Product of Origin』是日本。

日本對光觸媒的安全及效能有嚴格規範,2000年成立「日本光觸媒製品技術協議會」推出SITPA認証標誌;2006年成立「日本光觸媒工業會」亦推出PIAJ認証標誌獲認證的產品必須通過安全及效能測試,確保無毒無害。根據日本光觸媒工業會官網,目前只有日本生產的光觸媒才可申請認証。提醒,自行噴光觸媒時,緊記要戴口罩,保護氣管和肺部。

至於工程與自行噴灑的分別,主要是噴灑工具效果不同,工程用的專業工具可噴出平均全面的效果,DIY的效果相對粗糙不均,分解甲醛的效果最多可相差數倍。

5種您可能會忽略的家庭安全威脅 5 Home Safety Threats You Might Overlook

You're a careful parent who steers children away from things that could harm them. But hidden threats lurk in every house—sometimes where you least expect them. For safety's sake, look through your home often. Keep an eye out for not-so-obvious hazards. Here are 5 of them:

Scalding tap water 滚烫自來水

It is common for a home's water heater to be set above 120°F (48.8°C); this can cause a scald burn to a child in seconds. Scalding hot tap water causes 3,800 injuries and more than 30 deaths a year. A lot of victims are young kids.
Solution: Set your hot water heater to no higher than 120° F (48.8°C), and check the temperature of your tap water to ensure it is safe.

Unstable furniture 不穩定的家具

Each year, thousands of young kids are badly injured—and some die—when large TVs and heavy furniture tip over on them. Often, the victims were climbing it, or pulling themselves up on it, or falling against unstable furniture.
Solution: Double-check the stability of large furniture. Anchor stoves, bookcases, shelves, or bureaus to the wall. Get rid of items that may tempt kids to climb.

Window blinds 百葉窗

Hundreds of children have strangled to death after getting tangled up in cords or chains on window blinds. Window coverings sold before 2001 pose the most danger.
Solution: Secure the cords of older window coverings so children can't reach them or replace them with safer, cordless blinds. Move cribs, beds, and other furniture away from windows. Use only cordless window coverings in children's sleep and play areas. 

Poorly stored chemicals化學品儲存不當

Since the year 2000, the number of poisoning deaths has doubled among children. Many poisons are found in the garage, kitchen or bathroom. They include pesticides, automotive products, weed killers, and household cleaning and disinfectant products.
Solution: Store harmful chemicals in their original, labeled containers—safely out of reach. Consider locked cabinets for storage. Never leave chemicals unattended when you are using them.

Home trampolines 家庭彈翻床

Backyard trampolines send tens of thousands of people younger than 20 to doctors and emergency rooms each year. Injuries range from sprains, broken bones, and cuts—to neck and spinal cord injuries, paralysis, and even death.
Solution: Avoid use of home trampolines. In gym classes or competitive sports, use a trampoline only with strict adult guidance and supervision.
