In recent years, there have been more studies on the Vietnamese workers’s life in the industrial zones. However, the research on career and social status of the workers is still a desert. This article investigates how Vietnamese workers perceive their career and social status. Data were collected through survey by quantitative questionnaire and in-depth interviews with 800 samples in industrial zones of Binh Duong Province of Vietnam. Finding results show that: (1) The workers evaluated their career and social status at an average level in compared to other classes in society. (2) With an average level, the voices of workers have not received adequate attention from the companies, government and unions when conflict of interest occurs. The workers’s experiences in daily social interaction is one of the reasons why workers perceive themselves in lower status than other classes in the social hierarchy. Further studies should be attentioned on individual experience through discourse to understanding the worker’s life.

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).

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.

Binh Duong has rapidly transformed during the period 1999-2009, from a agricultural province to industrial one. The paper explores the shift of occupation-based social structure of Binh Duong during that period. Using the data sets of Census 1999 and 2009, the paper analyses the evolution of the occupational figure in Binh Duong by ten occupational categories and four occupational strata, and the differences in this figure by residence, gender, ethnic, and religious variables. Findings show that the occupational structure of Binh Duong is more developed than the one of the Southern Key Economic Zone. Its change in rural areas is more significant than in urban areas. There are not considerable differences by gender, ethnicity, and religiousness. The findings are suggestive for a further analysis using the data set of Census 2019 on the evolution of occupational figures in Binh Duong during the previous twenty years (1999-2019).
