| 1 | Determination of N-nitrosodimethylamine in drinking water by UPLC-MS/MS显示文摘The method for detecting N-nitrosodimethylamine(NDMA) in drinking water using ultra performance liquid chromatography(UPLC) coupled with tandem mass spectrometry(MS/MS) was improved by optimizing the clean-up procedure to remove the matrix interference in pretreatment process,and was then applied to a survey of NDMA in both raw and finished water samples from five water treatment plants in South China.The NDMA concentrations ranged from 4.7 to 15.1 ng/L in raw water samples,and from 4.68 to 46.9 ng/L in finished water.The NDMA concentration in raw water was found to be related with nitrite concentration,and during the treatment,the NDMA concentration increased following ozonation but decreased after subsequent activated carbon treatment. | Wanfeng Wang Jianying Hu Jianwei Yu Min Yang | 2010 | Journal of Environmental Sciences2010，22，10： | 16 |
| 2 | Comparative study on nutrient composition and antioxidant capacity of potato based on geographical and climatic factors显示文摘Potatoes are consumed in the human diet,but the environmental effects on the nutrient content of their tubers are not known.Five potato varieties from China(Chongqing,Dingxi,Qiqihar,Enshi,and Ulanqab)were selected to compare their nutritional components and antioxidant capacity and to explore the correlation between nutrition and local rainfall,humidity,temperature,and light time.The results indicated the Qiqihar cultivar presents significantly higher antioxidant capacity,and has the most elevated protein and soluble sugar contents.The total phenol(TPC)(325.07μg/g)and carotenoid contents(54.93μg/100g)of the Ulanqab cultivar were the highest.The Dingxi cultivar reveals the highest total flavonoids(TFC)(168.94μg/g),K,Mg,and P contents.The ascorbic acid content(26.09 mg/100g)was the highest in the Chongqing cultivar,and the contents of starch,Ca,total acid,and water were also prominent.The amino acid content(7.350%)in the Enshi cultivar is higher.It was found that soluble sugar was significantly correlated with humidity,temperature,and light time;carotenoids were affected considerably by rainfall;ascorbic acid has a strong correlation with temperature;TPC was moderately associated with humidity and light time.To summarize,tubers’nutrient composition and antioxidant capacity vary with geographical location and climate of origin.This study will help provide a theoretical basis for selecting geographical areas for potato planting and exploring the complex interactive factors between environment and vegetable attributes. | Bing Zhang Ayesha Murtaza Aamir Iqbal Jiao Zhang Tingting Bai Wanlu Ma Xiaoyun Xu Siyi Pan Wanfeng Hu | 2022 | Food Bioscience2022，46，2： | 1 |
