摘　　要：通过对消费者常使用的11种无磷洗衣粉的含磷量及COD的测定,得到磷与COD负荷值,以此估算了2000—2007年我国洗衣粉消费的磷、COD污染负荷总量。结果表明,被检洗衣粉磷与COD负荷平均值(w/w)分别为0.009±0.019和0.34±0.391;45.5%的被检"无磷"洗衣粉不符合国家标准规定的要求。对多年洗衣粉消费产生的磷和COD值估算结果表明,年平均值分别达1.616×104t和86.14×104t,并呈逐年上升趋势,增长率分别达180.15%和198.27%。洗衣粉消费引起的污染应引起消费者的共同关注。Phosphorus and COD content in 11 kinds of local laundry powder commonly used by consumers is tested,finding out the load value of phosphorus and COD,so as to estimate the total amount of phosphorus and COD pollution load of Chinese laundry powder used by consummers in 2000-2007.The results show that the average load value of phosphorus and COD is 0.009±0.019 and 0.34±0.391（w/w） respectively and About 45.5% of the tested laundry power labeled with ＂phosphorus free＂ cannot meet the Chinese National Standard toward the laundry powder;based on the above analytical results,it is estimated that the annual pollution load for phosphorus and COD is 1.616×104 t and 86.14×104 t respectively and what＇s more,the pollution load shows an ever escalating trend year by year with increasing rate of 180.15% and 198.27% for phosphorus and COD respectively.Obviously the powder detergents-induced pollution should arouse more attention by consumers.
