Briefly describe the tasks and objectives of environmental quality assessment.

The task of environmental quality assessment is to, based on a large amount of testing data and investigation results, use specific evaluation standards and methods to explain, determine, and predict the extent to which human activities affect human health, ecosystems, and the environment within a given area. The basic purpose of environmental quality assessment is to provide a basis for environmental management and planning. It also serves to compare the degree of pollution in different regions, thereby enabling the control, protection, utilization, and improvement of environmental quality to ensure it is suitable for human survival and development.

Task； From the perspective of environmental hygiene, the environmental quality within a certain area is investigated and studied using specific evaluation criteria and methods, upon which scientific, objective, and quantitative assessments and predictions are made. Purpose ； (1) To provide a comprehensive overview of the status of environmental quality and its trends over time; (2) To identify the key areas that require focus in pollution control; (3) To serve as a basis for formulating comprehensive environmental protection strategies, as well as urban and environmental plans; (4) To study the relationship between environmental quality and human health; (5) To predict and assess the potential impacts of proposed industrial or other construction projects on the surrounding environment, which is known as environmental impact assessment.

Environmental quality assessment is a scientific method used by people to understand and study the environment. Its task is, based on a large amount of testing data and survey analysis results, to use certain evaluation standards and methods to explain, determine, and predict the extent to which human activities in a given area affect human health, ecosystems, and the environment. The basic purpose of environmental quality assessment is to provide a basis for environmental management and planning. It also serves to compare the degree of pollution in different regions, thereby enabling the control, protection, utilization, and improvement of environmental quality to make it suitable for human survival and development.

Environmental quality assessment involves investigating and studying the environmental quality within a specific area from the perspective of environmental hygiene, using certain evaluation standards and methods, and on this basis making scientific, objective, and quantitative assessments and predictions. A comprehensive assessment of the environmental quality in urban areas should include evaluations of pollution sources, environmental quality, and environmental impacts. On this basis, a comprehensive evaluation of environmental quality can be conducted, and comprehensive strategies for controlling environmental pollution can be formulated to provide guidance for pollution control, environmental planning, and environmental management. The main purposes of environmental quality assessment are: (1) to comprehensively reveal the status of environmental quality and its trends over time; (2) to identify the key areas that require pollution control efforts; (3) to provide a basis for formulating comprehensive environmental protection plans, as well as urban and environmental planning; (4) to study the relationship between environmental quality and human health; (5) to predict and assess the potential impacts of proposed industrial or other construction projects on the surrounding environment, which is known as environmental impact assessment.
