How to reduce pesticide toxicity.

1. Placement. Many pesticides are catalyzed by oxidants or biological enzymes, and active substances such as oxygen in the air and enzymes in vegetables react with residual pesticides to oxidize and degrade pesticides, which can reduce the amount of pesticide residues and reduce their toxicity. For example, roots, fruits, and other vegetables that are shelf-stable can be stored for a period of time after being bought back to reduce pesticide toxicity.

2. Peel. Generally, the surface of vegetables has the highest amount of pesticide residues, and for melons and fruits such as cucumbers, eggplants, etc., it is better to peel and eat as much as possible.

3. Washing. Organophosphorus pesticides are mostly phosphate esters or amides, which are partially hydrolyzed in water to become low-toxic or non-toxic substances. Most chemical pesticides are acidic, and soaking them in 5% alkaline water can neutralize the reaction and reduce pesticide residues.

5% salt or fruit and vegetable detergent also has a good removal effect on organophosphorus pesticides. Vegetables that should not be peeled should be washed and soaked thoroughly before eating. Adequate washing can remove 75% to 85% of pesticide residues on the surface of vegetables.

For cabbage vegetables with a long growth period, the leaves need to be broken and soaked and rinsed leaf by leaf to achieve the purpose of removing pesticide residues.

4. Heating. Some pesticides volatilize or decompose at high temperatures. For vegetables such as lentils that are suitable for long-term heating, the cooking method of sufficient heating is conducive to reducing pesticide residues.

Consumers can also use a variety of treatment methods to remove pesticide residues and reduce or eliminate their harm to human health according to different types of vegetables.

The content about technology is:

1. Modern science and technology: high technology is like a messenger that communicates the reality and the future, guiding people to constantly open up space for development and move towards a dynamic new world. The contemporary scientific and technological revolution centered on information technology is booming around the world, marking the historic leap of mankind from an industrial society to an information society.

Information technology includes microelectronic technology, optoelectronic technology, computer technology, communication technology, imaging technology, display technology, etc.

2. Life science: Modern life science technology has been unprecedentedly developed in the 20th century, especially the discovery of DNA double helix structure and the implementation of the human genome project, which has made life science technology the mainstream of high-tech in the 21st century.

3. Space science: Space science is one of the fastest-growing cutting-edge technologies in contemporary science and technology. It has always been the dream of mankind to enter space, conduct scientific research there, develop unlimited space resources, settle down, travel, and even establish a space civilization.

4. Science and technology are the primary productive forces. In today's era, scientific and technological progress plays an increasingly decisive role in a country's economic and social development. We must unswervingly implement the strategy of rejuvenating the country through science and education, truly place the acceleration of scientific and technological progress in a key position in economic and social development, form our own scientific and technological innovation system as soon as possible, and make efforts to promote the effective transformation of scientific and technological achievements into real productive forces.

5. When we learn scientific and technological knowledge, we should first grasp the general trend of world development through this kind of study and strengthen our sense of urgency and responsibility to do a good job. An important reason why the Western capitalist countries have been dominating the world for several hundred years is that they first mastered and applied advanced science and technology, and formed an overwhelming superiority over other countries economically and militarily.

1. Science and technology are the primary productive forces. Looking at ancient and modern times, China and foreign countries, every progress of human society is accompanied by the progress of science and technology. In particular, the rapid development of modern science and technology has opened up a broader space for the development of social productive forces and human civilization, and has effectively promoted economic and social development.

The rapid growth of China's computer, telecommunications, biomedicine, new materials, and other high-tech enterprises has greatly improved China's industrial and technological level, promoted a substantial increase in industrial and agricultural labor productivity, and effectively promoted the development of the entire national economy. Practice has proved that high-tech and its industries have become the leading industries in contemporary economic development.

2. Science and technology are the hallmarks of human civilization. The progress and popularization of science and technology have provided mankind with new means for disseminating ideology and culture through radio, television, film, video, and the Internet, and have provided a new carrier for the building of spiritual civilization. At the same time, it is of great significance for enriching people's spiritual life, renewing people's ideological concepts, and breaking down superstitions.

3. The progress of science and technology has created tremendous material and spiritual wealth for mankind. With the advent of the era of knowledge economy, the never-ending development of science and technology and its unlimited creativity will continue to make greater contributions to human civilization. With the continuous expansion of the knowledge system of modern science and technology, the philosophy of science and technology (dialectics of nature), as the highest theoretical summary of the change and development of science and technology, has become increasingly prominent in the dynamic reaction of modern science and technology, and the increasing socialization, systematization and complexity of modern science and technology make science and technology must be included in the field of philosophy.

4. The relationship between science and technology varies from historical period, from the leading technology to the leading development of science, from the separation of technology and science to the precise combination of science and technology, the development of modern science and technology has shortened the time between basic scientific research and the application and development of technology, especially the birth of system science, which has led to automation, computer, The rapid transformation of communication technology from science and technology to industrialization, and the application of systems science to biomedicine have led to the coupling between systems biology and synthetic biology, which will quickly lead to the application of systems medicine and systems bioengineering, which will lead to the biomedical and bioindustrial revolution of individualized medicine, translational medicine and medical engineering systems, and make science and technology more and more prominent as the productive forces of social and economic development.
