\n\u003Cbr\u002F> 代谢和降解：环境中甲醛的主要污染来源是有机合成、化工、合成纤维、染料、木材加工及制漆等行业排放的废水、废气等。某些有机化合物在环境中降解也产生甲醛，如氯乙烯的降解产物也包含甲醛。由于甲醛有强的还原性，在有氧化性物质存在条件下，能被氧化为甲酸。例如进入水体环境中的甲醛可被腐生菌氧化分解，因而能消耗水中的溶解氧。甲酸进一步的分解产物为二氧化碳和水。进入环境中的甲醛在物理、化学和生物等的共同作用下，被逐渐稀释氧化和降解。甲醛的氧化降解过程如下：2HCHO+O\n\u003Csub>2\u003C\u002Fsub>---2HCOOH2HCOOH+O\n\u003Csub>2\u003C\u002Fsub>---2H\n\u003Csub>2\u003C\u002Fsub>O+2CO\n\u003Csub>2\u003C\u002Fsub>\n\u003Cbr\u002F>\n\u003Cbr\u002F>残留与蓄积：资料记载，工业企业区土壤中吸附的甲醛含量可达180-720mg\u002Fkg干土。土壤的污染可导致地下水污染，水中甲醛含量可以比表层土高出10-20倍。\n\u003Cbr\u002F>甲醛在环境中颇稳定，当水中甲醛浓度为5mg\u002FL时(20℃)，观察结果表明，5天内可以保持恒定。水中甲醛浓度为<20mg\u002FL时，可以被曝气池中经驯化的微生物降解消化。而含量为100mg\u002FL时，能抑制微生物对有机物的氧化。当水中甲醛含量为500mg\u002FL时，生物耗氧过程全部中止，水中微生物被杀死。\n\u003Cbr\u002F>\n\u003Cbr\u002F>迁移转化：甲醛由于沸点低又易溶于水，所以主要通过大气和水排放进入环境。生产甲醛的工厂其未处理的气体，当排放高度为18米时，其距工厂250-500米的大气样品中，甲醛含量均在0.035mg\u002Fm\n\u003Csup>3\u003C\u002Fsup>以上。1000米远在大气中甲醛浓度在嗅阈以下。以甲醛作鞣剂生产塑料的企业周围大气中的甲醛浓度在嗅阈以下。以甲醛作鞣剂生产塑料的企业周围大气中的甲醛浓度距厂区100米内为0.012mg\u002Fm\n\u003Csup>3\u003C\u002Fsup>；200米处36个样品中有15个浓度低于0.012mg\u002Fm\n\u003Csup>3\u003C\u002Fsup>；400米处均低于0.012mg\u002Fm\n\u003Csup>3\u003C\u002Fsup>。\n\u003Cbr\u002F>工业废水中排放的甲醛含量由于行业不同有很大差别，其中浓度最高的甲醛废水是生产酚醛树脂的上层焦油废水，含甲醛量高达2.5%。 \n\u003Cbr\u002F> 危险特性：其蒸气与空气形成爆炸性混合物，遇明火、高热能引起燃烧爆炸。若遇高热，容器内压增大，有开裂和爆炸的危险。\n\u003Cbr\u002F>燃烧(分解)产物：一氧化碳、二氧化碳。 \n\u003Ch3>3.现场应急监测方法:\u003C\u002Fh3>\n\u003Cbr\u002F>
