Abstract:
Objective To investigate the pollution of endotoxin in drinking water and the removal efficiency of endotoxin through the conventional drinking water treatment in Wuhan city,Hubei Province.Methods In Mar 2008,the water samples of Pinghumen and Zongguan drilking water plants which sourced from the Yangtze River and Hanjiang River respectively,were collected.The samples were tested by Limulus amebocyte lysate test recorded by Chinese Pharmacopoeia(2005 edition).Results The endotoxin content in raw water of the Yangtze River was(100.98?2.75)EU/ml and in tap water was(18.53?0.01)EU/ml.The endotoxin concent in the raw water of the Hanjiang River was(86.40?1.69)EU/ml and in tap water was(41.68?1.94)EU/ml.The removal rates of two drinking water plants were 81.65% and 51.76% respectively.Conclusion The conventional drinking water treatment can remove the endotoxin in dgreeds,but the content of endotoxin in the product water is still higher.
