Compare to other documents, our study was for the first time validated the quality criteria of ICP-MS for analyzing nineteen metal levels in wastewater samples. The application of this method was then tested by analyzing nineteen metal levels in twenty-three wastewater samples in the Tham Luong Canal in Ho Chi Minh City. Based on these results, the correlation of the concentration of these metals in wastewater samples was determined.

This study has adopted a systematic approach to identify the extent to which 20 kHz ultrasound affects the particle size and solubility of different protein solutions containing 4%, 7% and 10% whey proteins, caseins or a mixture at a range of energy densities (15-400 J/mL) and various pH (4.0-9.0). Milk proteins hold a prominent place in the food industry as they are used in many manufactured products for their functionality and most importantly nutritional benefits.

In this study, the AERMOD modeling system was used to evaluate the impact of the stack emission by the thermal power plants on the ambient atmospheric environment. The annual average concentrations of these pollutants indicate that the high terrain areas at the south and northwest of Cam Pha City, which block the flow of the stack emission, are the most affected regions by exhausted gases from industrial stacks.
