Cao Bang city, Cao Bang province Supervisor Assoc.Prof Do Thi Lan Abstract In recent years, environmental pollution is becoming worse Environmental protection is essential, especially for industrial areas Cao Bang Cement Factory is in Duyet Trung commune, Cao Bang province where the environment is being polluted Therefore, we have studied the establishment of “Assessment of current environmental quality at Cao Bang Cement Factory in Duyet Trung commune, Cao Bang city, Cao Bang province " The aim of the study is to assess the current sources of environmental pollution in Cao Bang cement factory and having measures to protect the environment as well Therefore, that citizen can study and work in a safe and clean environment In addition, this enables students to enhance their knowledge, awareness, and responsibility for the environment We conducted to collect documents, take samples to analyze the environmental quality Analyzing criteria of environment in Cao Bang factory, we considered it as the basis of evaluating the current state of the environment The results of analyzing air sampled showed that all the targets are within the permissible limits except the noise in cement works is quite high (86.1 dBA) exceeds 1.1 dBA Moreover, analysis of wastewater sampled in the factory in comparisons with QCVN 40:2011/BTNMT (National technical regulation on industrial waste water) showed that pollutants in waste water that are much smaller than the regulation allows However, index n numbers are still quite high such as the percentage of Mn is 0.641 mg/l while allowed standard is mg/l From results above, we can see that the environmental quality is severely polluted, so we have increased the effective solutions to minimize negative impacts on the environment, especially air environment Simultaneously, there are best solutions to minimize effects to local people as well as workers Keywords Environmental quality, Environmental pollution, Environmental protection, Citizen, Awareness, Assessment Number of pages pages Date of submission January 15, 2015 n
