In recent years, Vietnam has experienced urbanization and industrialization, leading to potential air pollution and climate change risks. To reduce these negative consequences of economic development, Vietnam has promoted a low-carbon economy (LCE) by setting many goals for green growth, air pollution reduction, and increasing the absorption capacity of greenhouse gases (GHGs) in many industrial sectors. However, there is still a lack of a specified policy to promote these goals systematically. This study proposes a set of criteria that could be used to evaluate and certify low-carbon industrial parks (LCIPs). The criteria were developed using Analytical Hierarchy Process (AHP), expert opinion, data normalization, and carbon emission calculation. The set of criteria includes five groups of indicators with eighteen criteria for evaluating LCIPs, which can be applied in Vietnam’s contexts. Using such an index system to Trang Bang IP in the period 2016–2020 as a case study, the results show that the Trang Bang has yet to meet the criteria of LCIPs, particularly in terms of energy consumption and GHGs emission.
The main objective of this study was to isolate and identify the aerobic bacteria in bacterial community of constructed wetland in Vietnam, which were spiked with benzene. For this target, four random samples of rhizosphere soil of phragmiteskarkas from constructed wetlands in Vietnam were collected and mixed together. The soil sample was labeled VS. Bacteria in the sample was grown in 80 mg/L benzene liquid media with optimal conditions of temperature and shaken to find out whether bacteria in the sample can remove benzene or not. The result showed that bacteria in the sample can survive and treat benzene well. Strains of bacteria were isolated through incubation in Burk's medium mixed with benzene. The strain named VS1 from VS sample was obtained. The strain adapted well in agar medium containing benzene as sole carbon source. Through molecular methods, VS1 was identified as PandoraeapnomenusaCM25.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
