What are the hazards of household chemicals and the harm of chemicals to the environment

List all the chemicals.

1. Pollution to the atmosphere: some volatile toxic chemicals, once leaked, will soon be emitted into the air, polluting the atmosphere and threatening the lives of humans or animals;

2. Pollution of soil: like pesticides, harmful chemicals in the soil continue to accumulate due to a large number of uses, and even harm groundwater;

3. Pollution of water bodies: due to the accidental leakage of some chemical plants or harmful and toxic chemicals, water pollution is caused, and a large number of water organisms, fish, shellfish and shrimp die, and even directly pollute drinking water sources. For example, chemistry such as the Songhua River pollution incident is a kind of natural science, which studies the composition, properties, structure and change laws of matter at the molecular and atomic levels, and creates new substances.

The world is composed of matter, and chemistry is one of the main methods and means used by human beings to understand and transform the material world. It is a discipline with a long history and vitality, and its achievements are an important symbol of social civilization, and today's society has been completely inseparable from chemistry.

The exploration of chemistry has been around since the beginning of human beings, because with human beings there is a need for chemistry. It is closely related to our lives and is everywhere in our daily lives. Mr. Yang Shi, a famous chemical predecessor in China, said

Agriculture, lightness, weight, eating, wearing, and using are all inseparable from chemistry. "Without the material civilization created by chemistry, there would be no modern life for human beings. However, mankind is facing the most serious environmental crisis in history, due to the rapid increase in population, the consumption of resources is expanding day by day, the per capita possession of arable land, fresh water and minerals and other resources is gradually decreasing, and the contradiction between population and resources is becoming more and more acute; as a national economy.

The chemical industry and related industries, one of the pillar industries, have made important contributions to the creation of human material civilization, but also continuously emitted a large number of toxic substances in production activities, which brought certain harm to the environment and human health. For example, the greenhouse effect.

Acid rain and ozone depletion are examples of environmental effects derived from air pollution. The environment will affect people's quality of life, physical health and production activities, and make people's living environment quality deteriorate. Serious pollution incidents not only cause health problems, but also social problems.

At present, environmental pollution problems have occurred to varying degrees in the world, and the aspects with global impact include atmospheric environmental pollution, marine pollution, and urban environmental problems.

Wait. As far as the environmental problems of the atmosphere are concerned, the main ones are acid rain, the greenhouse effect, the hole in the ozone layer, and photochemical smog. Wait.

Hydrofluorocarbons.

Freon refrigerants are broadly divided into 4 categories.

First, it is chlorofluorocarbon products, referred to as CFCS. It mainly includes R11, R12, R113, R114, R115, R500, R502, etc., which are listed as Class I controlled substances by the Montreal Protocol due to their destructive effect on the ozone layer and the maximum.

Second, it is hydrochlorofluorocarbon products, referred to as HCFCS. Mainly including R22, R123, R141B, R142B, etc., the ozone layer depletion coefficient is only a few percent of R11, therefore, HCFC substances are currently regarded as the most important transitional substitutes for CFC substances. In the Montreal Protocol, R22 is limited to 2020 and R123 to 2030.

Third, it is hydrofluorocarbons: referred to as HFCS. It mainly includes R134A (alternative refrigerant for R12), R125, R32, R407C, R410A (alternative refrigerant for R22), R152, etc., with an ozone depletion coefficient of 0, but a high warming potential.

It is not specified in the Montreal Protocol and is characterized as a greenhouse gas in the Kyoto Protocol to the United Nations Framework Convention on Climate Change.

Fourth, it is a mixture of refrigerants.

Hello! Please describe the problem in detail!

The hazards of some chemicals can be divided into two aspects: health and environment.

The emission of chemicals can lead to air pollution, air pollution and water pollution, disrupt the environmental balance, and affect the living environment of animals and plants.

In addition, some chemicals can cause irreversible harmful effects on the human body, such as a variety of cancers, nervous system, immune system and other diseases.

Therefore, the regulation and control of chemicals should be strengthened to minimize and control their emissions.

At the same time, the public should be made more concerned about the use and storage of chemical products to reduce the harm to human health and the environment.

For example, exposure to certain chemicals may cause inflammation or allergic reactions. Inhaling certain chemicals can cause respiratory problems, including asthma and lung infections. To make matters worse, certain chemicals have the potential to be carcinogenic, which means long-term exposure may cause cancer.

Chemicals are an inevitable part of our lives. They are used for a variety of different purposes, from detergents to pharmaceutical products. However, these chemicals also pose a number of potential hazards.

First of all, chemicals can be harmful to the human body.

Second, chemicals can also be harmful to the environment. Many chemicals produce toxic waste during the manufacturing process, which can contaminate soil and water sources. Additionally, certain chemicals may cause air pollution, which can negatively affect human and animal health.

To reduce these risks, it is important to ensure that chemicals are handled and stored correctly. This includes placing chemicals in a safe location and ensuring that they have not been exposed to other substances. When working with chemicals, people should wear appropriate protective gear, such as gloves and face shields, to protect themselves from hazards.

In addition, it is important to ensure that waste is disposed of correctly to avoid further harm to the environment.

In conclusion, chemicals are potentially dangerous. However, with proper handling and storage, people can minimize these risks as much as possible. Ultimately, this will help ensure that our living environment is safer and healthier.
