666 is a toxic substance with moderate toxicity, and it is required to avoid entering the human body through oral, respiratory and ** contact in the production, transportation, storage and use. The IMO of various countries recommends that in the process of transportation, 666 is a toxic substance, which needs special packaging and marking, has storage requirements, and should be separated from food such as grain during shipmentCare should be taken to remove contaminated means of transport. Due to the potential harmfulness of 666, many countries in the world have taken measures to stop production and use, and China is no exception.
However, a certain number of 666 finished products still exist in local areas, and even may still be used, and the poisoning accidents caused by them should be paid attention to.
When other isomers are replaced by high-propylene hexahexane, the good insecticidal effect of hexahexane pesticides can be maintained, so as to eliminate the chronic residual toxicity of and -hexahexane isomers. Because isomers are the most stable, persist the longest in the environment, and are the most chronically toxic, they accumulate 10-30 times more in adipose tissue than isomers. According to the results provided by the EPA in the United States, almost 100% of American human bodies have -666 residues, so dietary and environmental exposure are the main sources of pollution, and only by prohibiting the use of 666 can we really solve the problem.
-
Place a large number of plants at home, ventilate for 5 hours a day, and spray regularly with a sprayer into the house, and you can remove 66 powder in about 1 month.
-
It should be the taste, right?Or are you still alive?It is recommended that you open the windows for ventilation. Or find the local ** department, there is a department that is responsible for this kind of problem.
-
It's the taste, isn't it all discontinued?
-
It is an insecticidal drug, generally used for lice, jumping, ants and other insects, it is highly toxic, and people should stay away.
-
The use of highly toxic agricultural essentials is now prohibited.

Hexahexane powder, also known as hexachlorocyclohexane, is commonly known as lindane.
It is often applied to vegetables and fruits. It has contact killing, stomach poisoning and fumigation effects on insects.
It is a broad-spectrum insecticide used to control a variety of pests such as fruit trees, vegetables, rice, and cash crops. It is also a soil insecticide.
Toxic, teratogenic, and easy to remain. Not only can pesticides left on fruits and vegetables cause harm to people, but also in the soil, which can affect the growth of crops in the following year.
The pesticide has been banned in many parts of the world, including Chinese mainland. It is usually presented in a crystal-like manner, which is not easily soluble in water and is not easily biodegradable, which will affect the nerve center, liver and kidneys of the human body, and can easily lead to the birth of malformed babies.

The chemical name of hexahexane powder is hexachlorocyclohexane, the chemical formula C6H6Cl6, is a hexachlor substitute for benzene, also known as hexachlorocyclohexane, also known as hexahexahexane powder is highly toxic, once used as a pesticide, the state has expressly banned the production, sale and use of pesticides "Hexahexabhane" chemical formula structure and ** please see.
-
It is hexachlorocyclohexane, with the chemical formula C6H6Cl6, which is a hexachlor substitute for benzene and a derivative of hydrocarbons. Extremely insecticidal, the pesticide was once widely promoted in China and is now banned internationally.
-
Organochlorine pesticides (DDT, 666) have been used in large quantities around the world, causing environmental pollution and entering the human body through the food chain. China has banned the use of these two pesticides since 1983, but because this kind of pesticide has the characteristics of long half-life, not easy to decompose and lipophilic, it has caused long-term accumulation in human fat. In the early 80s, relevant experts predicted that after 15 20 years of deactivation of organochlorine pesticides (DDT, 666) in China, the accumulation level in the human body could be reduced to the level of some developed countries in the early 80s.

I know this smell, I think it must have been the east wind blowing that night, there is a chemical plant in the east of Shulinzhao Town, which is the smell emitted during the production process. It's okay. How many years have the employees been there, and there are no problems.
-
I don't know.. Your question is so regional!
-
Check with the relevant authorities, is there a factory near the village, if not, don't worry.
-
Note that it does not have a benzene ring. Product name: hexachlorocyolohexane 66 powder.
Scientific name: Hexachlorocyclohexane.
The benzene ring is a complex bond, not a single and double bond alternation, and the circle can indicate that we see it as a whole bond.
-
The ring in the benzene ring is the bond between c and c, and the position of the angle between each two wires is the position of c.
-
c6h6cl6 (hence the name six-six-six).
Hexahexane is a hexachlorine substitute for cyclohexane: hexachlorocyclohexane.
Chemical formula; Hexahexafen (the name when powdered).
English name: hexachlorocyolohexane 66 powder scientific name: 666 Chinese name.

The previous question was answered correctly on the first floor. The benzene ring is a regular hexagon with a circle inside, which originally had no circle, and inside are three evenly spaced lines, representing the alternation of single and double bonds. In fact, there is no difference between the six carbons of the benzene ring, so the circle is used instead.

Chinese name: 六六六; Hexachlorocyolohexane Hexachloro
Scientific name: Hexachlorocyclohexane Chemical formula: C6H6Cl6 (hence the name hexahexane).
Hexahexane is a hexachlorine substitute for cyclohexane, not a 6-chloro-substitute for benzene, and the 6-chloro-substitute for benzene is benzene hexachloride (C6Cl6) Many people confuse!
-
Hexahexa powder is an insecticide, also called "trichlorfon".
-
A pesticide. It is not allowed to be used.
-
The toxicity of hexahexa powder is actually not high, and even some pesticides that are being used now have higher toxicity than hexahexa powder in a short period of time, and hexahexabic powder is banned not because of its high toxicity, but because its structure is too stable and not easy to degrade in the environment, it can exist in the fat of animals through the food chain, and people are at the top of the food chain, and humans are enriched in the human body through ingestion, forming long-term harm to the entire environment.
-
After using it for decades, it was suddenly not allowed to be used, and now the ground is full of ants, and as soon as it is bitten, it will swell up, and it will be hospitalized in serious cases.
The inventions of chemists have propelled human progress and development. It is for the service of human beings, can make people do things that can not be done, modern workers lack this industry civilization allows people not to spend a lot of physical strength to do a task can be completed, hundreds of years of industrial civilization achievements more than thousands of years of human achievements, there is a great use. >>>More
