Disinfection by-product (DBP) research in China: Are we on
This review summarizes the main achievements on DBP research in China, which included: (1) the investigation of known DBP occurrence in drinking water of China; (2) the enhanced removal of DBP precursor by water treatment process; (3) the disinfection optimization to minimize DBP formation; and (4) the identification of unknown DBPs in drinking
Ecological Risk Assessment of Phthalate Esters (DBP and DEHP
According to Table 2, the concentrations of DBP and DEHP in surface water in China range from 0.01 to 133.7 μg/L and from 0.01 to 148.75 μg/L, respectively. The ecological risk of DBP and DEHP in six regions in China was assessed by HQ comparing the exposure concentrations and WQCs derived in this study.
SGS: High Levels of DBP Found in Chinese Wine Product
The supplier and China's Alcohol Association confirmed that high levels of Dibutyl Phthalate (DBP) had been found, but they explained that this incident might have been caused by the migration of DBP from plastic containers and pipelines used in production and storage.

DBP is also found in sediment and soil, and in aquatic and soil-dwelling organisms near to sources. The highest levels in air occur around PVC processing plants. More... 3.4 When DBP is present, it does not appear to have adverse effects on most organisms in the environment.
Dibutyl phthalate contamination accelerates the uptake and
In addition, DBP levels of up to 15.72, 15.11 and 57.7 mg/kg have been detected in Shandong Province (Jin et al., 2018), Hubei Province (Wu et al., 2015) and South Xinjiang (Lu et al., 2018), respectively. The toxicological effects of DBP in different organisms have been reported.
- How many DBP compounds are regulated in China's drinking water?
- In China, Standards for drinking water quality of China (GB/T5749-2006) was promulgated in 2006 and took effect in 2012, which regulated a total of 106 contaminants, including 14 DBPs. In terms of the number of regulated DBP compounds, the DBP regulations in the drinking water of China are more stringent than those in the United States.
- How to control drinking water quality risk induced by DBPs in China?
- Although the research of DBPs in China cover the whole formation process of DBPs, there is still a challenge in effectively controlling the drinking water quality risk induced by DBPs, an integrated research framework including chemistry, toxicology, engineering, and epidemiology is especially crucial.
- What are the research directions of DBP research in China?
- With respect to DBP research field, accurately qualitatively and quantitatively evaluating the formation level of known DBPs in drinking waters, optimizing the treatment process to minimize the formation of DBPs, and carry out frontier identification on unknown DBPs are currently the main research directions in China.

- Which universities authored the most DBP research papers in China?
- Among the remarkable DBP research papers authored from China, the top 10 most productive institutions in terms of publication numbers in China are plotted in Fig. 4, with Tongji University, Chinese Academy of Sciences (CAS) and Tsinghua University being the top 3 institutes.
- Will dwtps increase the operating complexity of DBPs in China?
- The DWTPs in China are attempting to optimize the combination of precursor removal and disinfection process to simultaneously meet pathogen reduction and regulatory limits on DBPs, which will in no doubt increase the operating complexity for DWTPs.
- What are the Wine Standards in China?
- At present, the most important current wine product standard in China, Wine GB 15037-2006, is mandatory. The standards system of wine in China is composed of a series of standards and relevant normative documents, pivoting on the Food Safety Law of the People’s Republic of China.
