The rubbish is burnt! Dioxin threatens human health seriously

The rubbish is burnt! Dioxin threatens human health seriously
Since January 15, 1990, Belgium, Holland, Germany, France cause and contain the poisoning of high density dioxin in beasts and birds products and dairy products because animal's feed is polluted by dioxin apart, have caused the extreme fear in Europe and even the whole world at one time. Dioxin is chlorine Third Ring Road aromatic hydrocarbon compound, praised as " repeats killers " the environment ,A toxicity extremely strong special organic compound, include many chlorine take the place of two and dioxin, many chlorine take the place of, take the place of, unite benzene,etc. by two the intersection of benzene and furan with many chlorine. Its toxicity is 50-100 times higher than sodium cyanide, it is 900 times higher than Arsenicum.
Pollution source
Dioxin in include, smelt while being a series of mainly and pulp bleach and produce some harmful by products produced under weed killer and industrial production process of insecticide, but there can also be volcano eruption and natural course such as the forest fire and emerge. It include, take the place of harmful by products formed in the hot course of the organic matter in chlorine of producing also at the same time. Wish outside, the car exhausts and cigarettes can produce dioxins to burn, because not totally burnt, burning to solid offal is causing dioxins to release on the main reason in the environment, in the developed country, dioxin produced to burn the domestic waste accounts for dioxins and always produces 95% in the source in fact, dioxin spread all over on include air, soil, water, precipitate, food (milk product, meat, and and ink have shell animals especially) in the world In all media inclusive. It is the highest in soil, precipitate and animal, the content in water and air is relatively low. Store the industry waste oil of dioxins with higher content in all parts of the world extensively. The long-term storage of this kind of material will cause dioxins to release to the environment, and then cause the pollution of mankind and animal food source.
Expose the route
Because the lipid solubility that dioxin has, memory is deposited in animal fat and milk, fish, poultry, domestic animal and egg, meat, milk are the food easiest to pollute. It is estimated, 90% of the crowds are through the diet (take animal food as the core) And the unexpected one is exposed to dioxin. Dioxin in the food is polluted and mainly discharged the thing (such as burning the rubbish, producing the chemicals) by all kinds of It causes dioxins due to farmland and serious deposition of liquid to accumulate the land and water food chain formed through the living beings. Pollute way, include animal feed is pollute also while being other, overflowing and discharge of the waste liquid and food processing of special way of animal husbandry wrong of the way to deal with filth of sewer,etc.. It engaged in on some it is special job ' pulp factory, paper mill, last factory and offal places dangerous) Workers may expose as dioxin at density getting higher environment
Mainly endanger
The route that dioxin enters the human body is mainly respiratory tract, skin and digestive tract. It can cause serious skin damaging disease, has the strong one carcinogenic and causing lopsided function, also have reproduction toxicity, immune toxicity and endocrine toxicity at the same time. If the human body is exposed to two evil Britain and Chinese of higher density in a short time, may know to lead to the fact the damage of the skin if presents chlorine analeptic and skin black spot, the change of liver function appears. If it will cause the damage to the nervous system, endocrine system and reproduction function in immune system, development to expose for a long time. Studies have suggested, exposed to the intersection of worker and their cancer mortality under the high the intersection of dioxin and environment of density than ordinary the intersection of crowd and high 60 percentage points. The most sensitive consequences brought include behind dioxin enters the human body: Membrane peculiar smell disease in the uterus, influencing the nervous system behavior (discern) Development effect, influencing reproduction (quantity, women of the sperm secrete the reproductive system deformity of the urine) Systematic development effect and immunity toxic effect.
Precautionary measures
It is still very difficult to deal with dioxin as to environment and mankind pollution-free material at present. Though is still studying other methods, still can yet be regarded as the most feasible method to burn, this kind of method needs more than 850 degrees of high temperature. In order to destroy a large number of materials polluted, even need 1000 degrees or higher temperature sometimes.
In order to reduce dioxins the danger to human health, the most basic measure is to control the discharge of dioxin in the environment, thus reduce it in silence with heavy food chain. Over the past ten years, whom a lot of developed country take control measure that dioxin release make incident to expose dioxin reduce greatly already. It is through the unexpected exposing to dioxin of diet because of 90% of the people, so, it is a very key link to protect the food and supply. The food pollution can take place until any stage of dining table. Guarantee the security of the food is one from production to continuous course of consuming. In initial production, processing, assigning and selling the course, good control and operation convention are essential for making safe food. The food pollution monitoring system must guarantee dioxins do not exceed fixed tolerance. Suspect there are contamination accidents while happening, the country should take the emergency measure to determine, arrest and handle those unsafe food. Should check on exposed intensity and influence to exposed crowd.
