Toxicology, simply put, analyzes and studies the entry of toxic substances into the organism, produces biochemical effects and changes in biophysics, disrupts or destroys the normal physiological functions of the organism, and results in specialized knowledge of body damage. In this world, there are many substances that are toxic to people's physical and mental health. With some highly toxic products, people may lose their lives when they are touched, others may not be very obvious, and the response may not be very rapid and dramatic, but it will cause long-term harm to the human body. With the improvement of people's living standards, people are paying more and more attention to environmental protection. Green packaging has emerged as the times require. However, in fact, the toxicological analysis and research in the process of production and use of the packaging and packaging industry are still insufficient. Poisoning has already occurred due to the improper use of packaging. In addition, scientific popularization, publicity and education are not enough, legislation and law enforcement are not in place, and the existence of local protectionism has made the problem more serious. In fact, carrying out toxicology analysis and research related to packaging not only involves environmental protection issues, but also relates to the market competitiveness and sustainable development of enterprises. Let's take a closer look at this issue.
First, toxicological analysis and research related to packaging First, the existence of toxic substances. Can be roughly divided into the following three situations:
1 The substance itself is toxic. For example, various pesticides, household pesticides, etc., many heavy metals such as lead, cadmium, mercury, arsenic and other chemical materials such as stupid, formaldehyde, cyanide, etc. are toxic, and some are highly toxic. These poisons must be properly packaged. And in the packaging process, try not to let the human body directly contact these substances.
2 The toxic substances contained in the product will volatilize and pollute the air during use. This situation is more common in the packaging industry. Paints and glues are commonly used in the packaging industry. Which may contain a variety of heavy metals and organic volatiles. Organic-based volatiles, such as formaldehyde, may be used in wood-based panels and paperboard, which are easily volatilized when molded into packages. Again, pigments used in making containers from crystal glass are often toxic. Making and using pottery can lead to problems with lead and cadmium poisoning. When making metal containers, you will encounter leaded solders and so on.
3 The product itself is not toxic, but it will produce toxic substances under certain conditions. Such as chemical reactions with other substances or thermal decomposition and so on. Many plastics decompose at high temperatures, producing a variety of toxic substances. Commonly used packaging materials, such as those known as "white pollution", produce toxins that damage the liver when they are above 60°C. If these materials are used for packaging, they must not be exposed to high temperatures. For example, automatic strapping machines can release harmful fumes when they are hot-melt adhesive plastic strapping, and they often run straight into the operator's eyes and mouth, irritating the operator’s eyes. And respiratory system. There is also a situation where these material packages are toxic to humans when used in food packaging. A common example is a normal polyethylene plastic bag.
Second, the harm of toxic substances to human health. There are roughly the following situations:
1 Corrosive. Such as various acids and alkalis, various detergents, removers and so on.
2 irritating. Various volatile gases can irritate people's eyes, nose and mouth, throat, etc. It can sometimes cause allergies and rashes.
3 toxicity. Toxic substances can affect almost all organs and tissues throughout the body.
Studies have shown that carbon monoxide, manganese, lead, mercury, methylmercury, etc. can damage the brain; carbon monoxide, sulfur dioxide, etc. will damage the heart; mercury and cadmium will damage the kidney; selenium, chlorinated hydrocarbons, etc. will damage the liver; fluorine, Lead, zinc, etc. can damage the bones; arsenic, bismuth, nickel, chromium, acid and alkali can damage the skin; chlorine and cadmium can damage the blood vessels; lead, fluoride, arsenic, vanadium, etc. can damage the intestine; fluorine and selenium can damage Teeth; Formaldehyde and other volatile gases can damage the eyes, nose, and throat; benzene can damage hematopoietic function; asbestos, dust, radon, sulfur dioxide, ammonia, cadmium, ozone, nickel carbonate, hydrogen sulfide, etc. can damage the lungs and so on.
4 radioactive. Many printing machines and detection equipment used in the packaging industry generate ionizing radiation. Nowadays, people are generally concerned about major toxicities to the human body, such as fatal or carcinogenic, while neglecting other forms of poisoning to people's physical and mental health, such as headache and lack of energy.
