The full name of dioxin is polychlorinated dibenzo-p-dioxin and polychlorinated dibenzofuran. The microbes and hydrolysis of nature have little effect on the molecular structure of dioxins. Therefore, it is difficult for natural dioxin to be eliminated by natural degradation. It includes 210 compounds. It is very toxic, 900 times that of pi cream. It is known as the poison of the century. One ten thousandth or even one hundredth of a gram of dioxin can cause serious harm to health. In addition to its carcinogenic toxicity, dioxins also have reproductive toxicity and genotoxicity, which directly harm the health and life of future generations. Therefore, dioxin pollution is a major issue related to the survival of mankind and must be strictly controlled. The International Agency for Research on Cancer has listed it as a human primary carcinogen.
Dioxin source
Waste incinerators, including: municipal domestic waste, hazardous waste, medical waste or multi-purpose incinerators for sewage in sewers; cement kilns burning hazardous waste; pulp production using elemental chlorine or chemicals that produce elemental chlorine as bleach The following heat treatment processes in the metallurgical industry; regenerative production of copper, sintering plants in the steel industry, regenerative production of aluminum, and regenerative production of zinc. There are also open burning wastes, including landfill incineration, and household burning sources. It can be said that dioxin is produced in places where there is burning.
Dioxin detection and analysis
At present, the investigation and control of dioxins at home and abroad are also paid more attention. There are also research institutions, research projects to eliminate dioxin, and control and control of dioxins are urgently needed.
Sample collection and pretreatment
Extraction of dioxins
Purify sample
Enrichment of dioxins
Active Pharmaceutical Ingredients
Active Pharmaceutical Ingredients(API) refer to the raw materials used in the production of various preparations. They are the effective ingredients in the preparations. They are various powders, crystals, extracts, etc., prepared by chemical synthesis, plant extraction or biotechnology, but Substances that the patient cannot take directly. API is intended to be used in any substance or mixture of substances in the manufacture of pharmaceuticals, and when used in pharmaceuticals, it becomes an active ingredient of the pharmaceuticals. Such substances have pharmacological activity or other direct effects in the diagnosis, treatment, symptom relief, treatment or prevention of diseases, or can affect the function or structure of the body. According to its source, active pharmaceutical ingredients are divided into two categories: synthetic chemical active Pharmaceutical ingredients and natural chemical active Pharmaceutical ingredients.
