What is Chemical Environment What is Environmental Chemistry

In thermodynamics, in order to clarify the object of study, the part of matter or space under study is often divided from other surrounding matter or space, and it is called a system, also known as a system.

The other parts of matter and space that are connected to the system are called surrounding

According to the exchange of energy and matter, the system is divided into three categories:

1. Open system, also known as open system. There can be both material and energy exchange between the system and the environment.

2.A closed system is also known as a closed system. There is only an exchange of energy between the system and the environment, but no exchange of matter.

3.Isolated system, also known as isolated system. There is neither material nor energy exchange between the system and the environment.

Definition: The study of chemical phenomena and their environmental and ecological effects that occur in the Earth's environment.

Environmental chemistry is one of the important sub-disciplines of environmental science, which studies the migration, transformation and degradation of chemical substances in the environment and the role of chemical substances in the environment. The Research Center for Eco-Environmental Sciences of the Chinese Academy of Sciences also hosts the academic journal Environmental Chemistry. In addition, there are a variety of books called "Environmental Chemistry".

Hope it helps!

It refers to the environment in which the chemical properties produced by the constituent factors of soil, water, air, etc., have a certain effect on the life of living organisms.

Environmental chemistry is a discipline that studies the migration, transformation and degradation of chemical substances in the environment, and studies the role of chemical substances in the environment.

Environmental chemistry is a science that applies the principles, methods and techniques of chemistry to study the transformation, fate and control of chemical substances (especially chemical pollutants) in the ecological environment system, as well as the ecological effects.

Environmental chemistry mainly studies the chemical principles and methods of the existence, chemical characteristics, behavior and effect of harmful closed front substances in environmental media and their control.

Analysis: One of the important sub-disciplines in environmental science. The factors that cause environmental pollution can be divided into three aspects: physical, chemical and biological, and the pollution caused by chemical substances accounts for about 80% and 90%.

Environmental chemistry is from the perspective of chemistry, the law of change of environmental quality caused by human activities and the methods and principles of environmental protection and governance. In terms of the main content of its destruction, in addition to studying the detection methods and principles of environmental pollutants (belonging to the scope of environmental analytical chemistry) and the chemistry, chemical principles and chemical processes in environmental pollution and treatment technology, environmental chemistry needs to further study the origin, migration distribution, mutual reaction, transformation mechanism, state structure change, pollution effect and final destination of chemical pollutants in the environment at the atomic and molecular levels. With the deepening of environmental chemistry research, which liquid has laid a solid foundation for the development of environmental science and provided an important scientific basis for the control of environmental pollution.

The main research areas and contents of current environmental chemistry:

1.The basic laws of migration and transformation of pollutants (mainly chemical pollutants) in the environment (including atmosphere, hydrosphere, soil, lithosphere and biosphere) are studied, and environmental pollution chemistry is a new marginal sub-discipline between environmental science and chemistry.

2.The types and compositions of pollutants in the environment and their quantitative analysis methods are studied to form environmental analytical chemistry (often referred to as environmental analysis). It is a sub-discipline of environmental chemistry.

3.To study the migration and transformation of natural and human-released chemical properties in the environment and their relationship with environmental quality and human health, and to form environmental geochemistry. It is an emerging marginal sub-discipline between environment and geochemistry.

Chemistry is the basic science on which human beings depend, the science that provides materials and medicines for human beings, and the science through which human beings understand, transform and control nature. Since chemistry provides the basic material for other sciences, it is also the basis for the development of other sciences. At present, the development of high technology is largely due to the development of high-tech materials, and at the same time, high-tech has in turn promoted the development of chemistry.

In other words, chemistry provides a variety of new materials for other disciplines, and other disciplines provide new equipment, new methods, and new means for chemistry.

In the process of implementation, chemical engineering can easily produce by-products that are not needed by human beings, which affect the environment and cause environmental pollution due to improper treatment or unavoidable. However, the treatment of environmental pollution and the treatment of various by-products can only be improved by relying on chemical means. Therefore, chemistry is also needed to improve the environment.

In fact, environmental pollution is not all the responsibility of the chemical industry, other industries also pollute the environment, but the pollution of the chemical industry is more direct and more obvious. Treatment, overcoming and controlling these pollution are inseparable from chemistry. It is only through chemical means that it can be fundamentally cured.

Therefore, it can be said that chemistry and the environment go hand in hand.

In addition, human activities inevitably deplete natural resources, and this consumption inevitably leads to changes in the natural environment. To recognize these problems and control the negative effects of this change on the world, all disciplines must do everything in their power to minimize the negative effects. That is, human beings must do their best to recognize and control nature and control themselves.

There is no fault in scientific disciplines, and human beings should not have any prejudice against scientific disciplines, so that it is possible to make human beings better.

Let's start with their definitions, and then learn more about relationships. Definition: Environmental chemistry is one of the important sub-disciplines in environmental science.

It is a science that mainly applies the basic principles and methods of chemistry to study the characteristics, state of existence, chemical transformation process and its change law, chemical behavior and chemical effects of chemical substances in environmental media such as atmosphere, water, and soil. Environmental science is the study of the relationship between humans and the environment. An integrated approach to the study of environmental systems.

Most environmental problems involve human activities, so knowledge from the social sciences can often be used in environmental science research. It is a discipline that studies the interaction between human activities and the environment, and seeks ways and methods for the co-evolution and sustainable development of human society and the environment. Relationship:

At the macro level, it studies the antagonistic and unified relationship between human beings and the environment, which promotes each other and restricts each other, and reveals the basic laws of coordinated development of social and economic development and environmental protection. At the microscopic level, it studies the accumulation process and movement laws of molecules and atoms of pollutants in the environment, especially pollutants emitted by human activities, and explores their impact on life and its mechanism of action.
