On July 5th, research conducted by Associate Professor Dr. Nguyen Van Thuoc from Ho Chi Minh City University of Technology revealed that 1.6 tons of hazardous industrial chemicals are released directly into the environment each year, accompanied by harmful emissions such as phenol, methylbenzene, and benzene.
A multitude of health issues arise from exposure to these toxic gases, including dermatitis, headaches, cerebral hemorrhage, skin cancer, and testicular cancer. Associate Professor Dr. Nguyen Van Thuoc has employed biological methods to treat these emissions. For less polluting gases such as Cyclic, biological filtration is sufficient, achieving treatment efficiency of 80% to 90%. In contrast, for hazardous emissions, all four biological processes are applied: biological filtration, biological trickling towers, drip filtration, and biofilm for organic and inorganic compounds in the emissions that are highly toxic. This method has been tested and has demonstrated treatment efficiency exceeding 90%.
It is worth noting that this is one of the cost-effective methods, with low operational and investment costs compared to other chemical methods currently available. Ho Chi Minh City is also in the process of implementing this method for industrial emission treatment.
