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. 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 4 numbers are still quite high such as the percentage of Mn is 0.641 mg/l while allowed standard is 1 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.

Background and rationale Nowadays, the environment is the top concern of all countries and the international community. Along with the development of society, the environment is being polluted by the devastation and development of human, especially the problem of air pollution. Humanity has polluted the atmosphere severely, causing a negative impact to the people, to the ecosystem as well as the lives of other creatures. In recent years, economy is growing faster bring about sources of environmental pollutants.
Vietnam is a developing country but there are no measures to protect the environment properly, thus causing great pressure on the environment. Pollution in major industrial parks, factories and big cities is becoming increasingly serious, having negative impact to the landscape and human health. Therefore, environmental protection is a top priority of the Party and State which are interested in strategic socio-economic development in the period of industrialization and modernization of the country. Cao Bang province is raising economy with the decreasing proportion of agriculture, increasing proportion of industry, construction, trade and services, the rate of urban development as well as industrialization are taking place very quickly.
Cao Bang is one of the provinces where economic growth is high with many areas such as metallurgical industry, Ferromanganese production, and cement production, mining. These activities have adverse effect to environmental quality in Cao Bang. 2 Cao Bang Cement factory has operated for a long time (1997) with outdated the equipment and operating facilities. Although the operation of the plant are bringing socioeconomic benefits, the negative impact on the environment is still not inevitable.
Therefore, the review of the status of ambient air quality in Cao Bang Province is very interesting. Stemming from these problems and realizing the importance of the evaluation of the current environmental quality with the adoption by consensus of the managing board of the University, the board of directors of International Development and Training Centers - Thai Nguyen University of Agriculture and Forestry, along with the direct guidance of Asso Prof. Do Thi Lan, I conduct research project “Assessment of Current Environmental Quality at Cao Bang Cement Factory in Duyet Trung Commune, Cao Bang City, Cao Bang Province” to support the management of environmental protection of Government in Cao Bang city, which proposed some measures in protecting and improving the environment towards the sustainable development. To assess the current environment 1.
To analize the sites which are exited and limited in manegement of environmental quality 1. To propose the solutions in environmental protection. Research questions - What is an overview of Cao Bang Factory? - What is current situation of air and water environment in Cao Bang Cement Factory? - What can human do to reduce impacts on human and environment? 3 1. Significations of the study 1.
Learning and scientific research significance - To apply the knowledge in to practice - To enhance the knowledge in real life - To supplement experiences in work after the graduation 1. Practical significance - To assess the impacts of Cao Bang Cement Factory on ambient environment. - To evaluate the efficiency of waste treatment system. - To suggest the solutions to manage, to reduce and to treat environmental pollutions.
Limitations - Due to limitation of time and resources, this study mainly foucues on the air and water environment in Cao Bang Cement Factory - The measurement and sampling time is only done 2 times/ year. So, the samples cannot in reflect the entire of pollution - The study solely mentions to the wastewater and air of Cao Bang Cement Factory in short term of early 6 months in 2014 1. Definitions This study assesses the status of wastewater and air environment of Cao Bang Cement Factory on early 6 months in 2014 peroids in order to determine the impact of wastewater and emission to the environment. Therefore, a number of solutions are propose to mitigate the effects to the environment surrounding the factory.
Scientific basis of topics 2. The definition of environment Environmental management is an activity in the field of social management, with adjustable impact of human activities based on a systematic approach with information coordination skills for environmental issues related to humans, derived from the quantitative point of view towards sustainable development and rational use of natural resources (Nguyen Ngoc Nong et al, 2006) [11]. Governmental management in environmental protection is a specific content in governmental management. It is the use of management tools based on science, economics, law to organize actions to ensure a balance between economic development - social, and environmental protection, including synthesis of legal measures, policy, technical, social appropriate to protect the environmental quality of life and economic sustainable development of the national society (Environmental Science General Le Van Khoa, 2001 ) [9].
- Environment definition In section 1 of Article 3- Environmental Protection Law on November 29, 2005 states: "Environmental factors including natural and man-made material surrounding human life affecting production, the survival, and development of human beings and other creatures "[7]. - Environmental components: 6 Environmental components are the physical elements that constitute the environment such as soil, water, air, sound, light, organisms, ecosystems and other physical forms. - Environmental function Environment is the living space of humans and other creatures. Environment provides the necessary resources for life and human production activities.
Environment is a place containing the human waste generated by life and its manufacturing operations. Environment mitigates the adverse effects of natural and human-beings on earth. Environment storages and provides information to human. - The concept of environmental protection: Environmental protection activities are to keep the environment healthy and clean; prevent and limit adverse impacts on the environment and respond to environmental incidents; pollution and degradation, restore and improve the environment; extract, use and save natural resources properly; protect biodiversity.
The concept of environmental pollution - According to the World Health Organization: "Environmental pollution is the transfer of energy or waste to environment which likely causes harming to human health, development or degrading organisms or reducing environmental quality ". - According to section 6 of Article 3- Environmental Protection Law in 2005: "Environmental pollution is the transformation of the components of the environment, which are not consistent with environmental standards, adversely affecting human beings. + Water pollution: "Water pollution is a negative change in the term of the physical - chemistry - biology properties of water, with the presence of foreign substances in liquid, solid leading water become toxic to humans and animals.
