Abstract:
Objective To assess the risk of nonylphenol in reclaimed wastewater used in city to damage the human endocrine system and to present the data for making the related water quality standard. Methods Based on the monitored results of nonylphenol in the reclaimed wastewater from a reclaimed water plant in Beijing and referenced the phenol toxic parameter from integrated risk information system of the Unite State Environmental Protection Agency and the nonylphenol tested toxicity data from related literature, the risk assessment of nonylphenol on human health was conducted using four step health risk assessments when the sewage was reclaimed as a different approach to use. Results The endocrine disruption risk of nonylphenol in reclaimed wastewater on human health was about in a range of 10-8-10-10, which could even be ignored. Conclusion The risk of nonylphenol is acceptable to human health when the reclaimed wastewater were used for municipal, agricultural irrigation, urban lake supplement, then, nonylphenol as a human health risk factor can be ignored when making the standard of nonylphenol in reclaimed water.
