装修污染来源
Source of decoration pollution
装修污染气体主要有甲醛、苯、氨和TVOC等，其中甲醛已经被世界卫生组织确定为致癌和致畸形物质。甲醛主要来源于室内建筑材料和家具，如胶合板、刨花板、泡沫填料、木地板、壁纸、油漆和涂料等。甲醛的主要危害表现为对皮肤粘膜的刺激作用，甲醛是原浆毒物质，能与蛋白质结合、高浓度吸入时出现呼吸道严重的刺激和水肿、眼刺激、头痛。 在所有接触者中，儿童孕妇和老年人对甲醛尤为敏感，危害也就更大。苯及TVOC等物质钢制闸门 钢坝 保定轻钢别墅 保定平面设计培训 保定室内设计培训 保定办公家具 保定空调维修 主要来自涂料、油漆及家具使用的胶黏剂，影响中枢神经系统，出现头晕、头痛、无力、胸闷等症状；感觉性刺激，嗅味不舒适，刺激上呼吸道及皮肤。氨主要来自建筑过程中混凝土里面添加的防冻液、尿素等，短期内吸人大量的氨可出现流泪、咽痛、声音嘶哑、咳嗽、头晕、恶心等症状，严重者会出现肺水肿或呼吸窘迫综合症，同时发生呼吸道刺激症状。
Decoration pollution gases mainly include formaldehyde, benzene, ammonia and TVOC, among which formaldehyde has been identified as carcinogenic and teratogenic substances by the World Health Organization. Formaldehyde mainly comes from indoor building materials and furniture, such as plywood, particleboard, foam stuffing, wood flooring, wallpaper, paint and paint. The main harm of formaldehyde is to stimulate the skin and mucous membrane. Formaldehyde is the original plasma toxic substance, which can combine with protein. When inhaled in high concentration, it will cause serious irritation of respiratory tract, edema, eye irritation and headache. Among all contacts, pregnant children and the elderly are particularly sensitive to formaldehyde, which is even more harmful. Benzene, TVOC and other substances mainly come from coating, paint and adhesives used in furniture, which affect the central nervous system and cause dizziness, headache, weakness, chest distress and other symptoms; sensory stimulation, uncomfortable smell and taste, and upper respiratory tract and skin stimulation. Ammonia mainly comes from the antifreeze and urea added in the concrete during the construction process. In a short period of time, when a large amount of ammonia is sucked into the concrete, tears, sore throat, hoarseness, cough, dizziness, nausea and other symptoms may occur. In serious cases, pulmonary edema or respiratory distress syndrome may occur, and respiratory tract irritation symptoms may occur at the same time.
