Applying the AQI ( Air Quality Index) to evaluate the current air in 03 research areas: Go Dau Industrial Park, Long Thanh Industrial Park, and Binh Son commune in Long Thanh district. From there, create a table comparing the air quality of these three areas over the years from 2017 to 2020. On that basis, propose solutions to control and improve air environmental quality in the research areas. Assessment results can be used as a data source to build air quality zoning maps. Provide environmental information to the community in a simple, easy-to-understand, and intuitive way. It helps raise ecological awareness. The primary method used in this study is the method of calculating the air quality index Vn_AQI issued by the Vietnam Environment Administration.

In the context of economic integration along with the development of industrial parks, enterprises are always innovating modern and advanced technology, improve the quality of products of enterprises to increase competitiveness in international economic integration. This study assesses the progress of completion, the inadequacies after applying the drawing management process in iso room age Vietnam and the management storage regulations of the enterprise, thereby making flawed comments and propose solutions in the management process after being put into practice at the company. Use interdisciplinary research methods of archiving, drawing records, survey results and speaks to the importance of managing and storing drawings in the mechanical engineering industry.showing the level of completion and outstanding shortcomings of the process. The survey results provide the basis for the shortcomings, which need to be improved in the process and thorough remedies to improve the quality of technical drawing management process

This study aims to assess environmental risk using the improved Nemerow index and the principal component analysis (PCA) method in Long Thanh's Industrial Park in Dong Nai Province. The study was implemented in five industrial parks of Long Thanh District in 2019. The result showed that Loc An - Binh Son industrial park was at extreme high risk of the level (6.7). Three industrial parks of Long Thanh, Go Dau and An Phuoc were high-risk (from 3 to 5) respectively. On the other hand, Long Duc Industrial Park has obtained no environmental risk.

Study on sampling sludge from 04 industrial parks in Binh Duong province such as My Phuoc, Dong An, Viet Huong 1, Song Than 2 to analyze the pollution criteria to assess the pollution possibility of industrial waste sludge. The research results show that: at present, the total volume of sludge generated today in the industrial park fluctuates about 4,450 – 6,255 kg/day, equivalent to dry sludge volume is 1,035.725 – 1,532.11 kg/day. The estimated volume of dry sludge generated from industrial parks in the future from 2019 to 2020 ranges from 30,023 to 31,396 kg/day. Most sludge from 04 wastewater treatment plants hadn’t heavy metals (Hg, Pb, Cu, Ni, Cr, Zn, Cd), especially Dong An Industrial park Treatment plant had Zn, value 49.7 – 49.9 mg/l. The sludge from the wastewater treatment plants of 04 industrial parks had amount of helminth eggs that exceeds the USEPA's regulations on pathogens (type A sludge).

Bien Hoa City is an urban area of Dong Nai province located in the Southern key economic region. Currently, Bien Hoa City has 6 industrial parks in operation with large daily wastewater flow, causing environmental risks, especially from organic pollutants. The study applied the Nemerow risk index and the geographic information systems (GIS). The results showed that the industrial parks were mainly organic pollution levels including N-total, P-total, and Ammonium. The level of environmental risk from organic pollution was recorded in range of medium to very high levels, the ranked in descending order: Agtex Long Binh Industrial Park (P = 24)> Amata Industrial Park (P = 16)> Bien Hoa 2 Industrial Park ( P = 10),> Tam Phuoc Industrial Park (P = 5)> Loteco Industrial Park (P = 3). The results of the study provided good information for the management and improvement of wastewater quality in the industrial wastewater treatment plants of the industrial parks in Bien Hoa City.

Measuring environmental protection activities is a matter of great concern over the years. In this study, the indicators for evaluating environmental protection activities in industrial parks was built according to the PDSIR model and based on Vietnam's legal framework, including 18 main subjects and 35 indicators. The environmental performance index of industrial park (EPIIP) was established based on the multi-criteria evaluation method and the analytic hierarchy process method. The results of the study indicated that the VSIP I industrial park reached 68.95 points (relatively good level). Moreover, the results also showed that VSIP I was one of the industrial parks practicing good performance to protect environmental problems.

The study was conducted at Fuji Seal Vietnam Co., Ltd. to examine the exposure and health risks of workers working in the printing and ink phase area when exposed to solvent vapor through the respiratory apparatus Toluene, Methyl Ethyl Ketone, Ethyl Acetate, Isopropyl Acohol. The results show that: During the monitoring period from July to November 2016, the amount of solvent vapor in the printing area and ink phase is quite high, at the highest Toluene printing area, it was 2.63 times higher than the standard equal to the health risk HQ male is 2.61 and HQ female is 3.37; Ethyl Acetate exceeded the highest of 4.34 times equal to the male HQ risk ratio of 4.29 and female HQ equal to 5.53; MEK exceeds 8.43 times equal to the health risk HQ male is 8.36 and HQ female is 10.79; Isopropyl Acohol exceeds 8.4 times equal to the health risk HQ male is 8.33 and HQ female is 10.75; At the inking area, MEK exceeds 8.43 times equal to the health risk HQ male is 8.36 and HQ female is 10.79. From the calculated data - analysis, found that the health of workers working in the printing and inking areas had high risks, the ability of workers suffering from diseases such as he dache, dizziness, skin damage,... and especially respiratory failure.
