2025年2月24日 · Volatile organic compounds (VOC) means any compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates and ammonium carbonate, which participates in atmospheric photochemical reactions, except those designated by EPA as having negligible photochemical reactivity 2.

2025年2月24日 · Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors.

VOC (volatile organic compounds) are all compounds that appear in the gas chromatogram between and including n-hexane and n-hexadecane. Compounds appearing earlier are called VVOC (very volatile organic compounds); compounds appearing later are called SVOC (semi-volatile organic compounds).

中華民國行政院環境保護署環署的標準較寬鬆，訂定總揮發性有機化合物 (TVOC)含量為少於0.56ppm (等同1287微克/立方米,1287μg/m³,1.287毫克/立方米或560ppbv0.2) [2] 中華人民共和國頒布的《民用建築室內環境污染控制規範》中，室內空氣中TVOC的含量，已經成為評價居室室內空氣質量是否合格的一項重要項目。 在此標準中規定的TVOC含量為Ⅰ類民用建築工程：0.5 mg/立方米、Ⅱ類民用建築工程：0.6mg/立方米 (等同600微克/立方米,600μg/m³,261ppbv或0.261ppm) …

2022年11月21日 · Low-VOC paint means that the paint contains less than 50 grams per liter of volatile organic compounds. No-VOC or zero-VOC paint can still have some VOCs, but it must have less than 5 grams per liter. Even if they have no or low VOC, these paints may still contain other harmful chemicals.

VOCs包含各種可於室溫下揮發的有機化合物。 在一般的室內環境中,有過百種化合物(包括甲醛)可歸類為VOCs。 這些VOCs可由多種不同源頭釋出,包括建造物料、 • 應依照製造商的指示處理油漆、黏合劑、清潔劑及其他含VOCs的產品,以及避免在沒有適當通風的密封空. 間內使用這些產品。 • 選用釋出較少甲醛及VOCs的實木家具。 避免選用無覆蓋的壓木家具,應選擇以膠板或防水物料覆蓋表面和邊緣的壓木製品,以減少釋出甲醛。 天或數周,讓它們先透氣然後才放入室內。 於入伙前 …

2024年7月19日 · What Does Low VOC Mean? Low VOC refers to volatile organic compounds that are not harmful to the environment and humans. It mostly refers to paints and other products that have a very low or zero VOC, e.g. sealants, adhesives and cleaners. Low VOCs are good for both the environment and living organisms.

2024年8月13日 · Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors.

2024年10月21日 · Volatile organic compounds, or VOCs, are gases that are emitted into the air from products or processes. Some are harmful by themselves, including some that cause cancer. In addition, some can react with other gases and form other air pollutants after they are in the air. VOCs can be found in the air indoors and outdoors.

2025年1月29日 · When you hear the term volatile organic compound (VOC), you might picture something complex and scientific. But here’s the simple truth: VOCs are a large group of organic chemical compounds that easily turn into gases at room temperature. Essentially, their main traits are high vapor pressure and low water solubility.
