Distribution,transport and effects of bisphenol A and nonylphenol in corn with reclaimed water irrigation
Reclaimed water irrigation is an important measure to alleviate water scarcity in agriculture.However,the health risks of endocrine disruptors in reclaimed water are unclear.In this study,we investigated the accumula-tion and transport patterns of nonylphenol and bisphenol A in the soil-corn system using a pot experiment.We eval-uated the effects of nonylphenol and bisphenol A on root characteristics and maize yield.The results show that 1)the levels of nonylphenol and bisphenol A in soil and maize plants increased with initial concentration.The levels of nonylphenol and bisphenol A in the root system of maize are higher than those in the stems and leaves,and the lev-els of nonylphenol and bisphenol A in the root system range from 0.0450 to 0.1575 mg/kg and from 0.3344 to 1.1344 mg/kg,respectively.2)The treatments at higher concentrations has signifi cant inhibitory effects on maize root and yield indices,and there are inhibitory effects on root length,root volume,root surface area,cob thickness,cob length,and 100 kernel weight,respectively.3)Bisphenol A and nonylphenol have weak transport capacity in vari-ous tissues of maize,and the transport coefficients of bisphenol A and nonylphenol are mostly less than 1.
