How harmful is the leakage of C9 in Quangang, Fujian Province

4, Fujian Donggang Petrochemical Company 6.97 tons of carbon nine leakage. Some fishermen were ill and hospitalized after rescuing the fish row. I believe that many people don't know what carbon nine is. Today's editor will come to popularize science for you and explore the harm to human body.

Wu Lixin, a researcher at Fujian Institute of physical architecture, Chinese Academy of Sciences, said that C9 is a flammable dangerous product with anesthetic and irritant effects. Inhalation and exposure to high concentration of this product's steam will cause eye, nose, throat and lung irritation, headache, dizziness, etc., and long-term repeated exposure can cause skin degreasing; eating contaminated animal and plant seafood, as well as the risk of poisoning and carcinogenesis.

Leakage of 6.97t C9 due to aging of hose

Previously, media reported that since 3:00 a.m. on November 4, the air in Shangxi village, Houlong Town, Quanzhou City, Fujian Province, and Fengqian village and Fengwei town had peculiar smell, which spread in the main urban area along with the wind direction and wind speed, and some sea areas had yellow brown oily leakage. According to the preliminary investigation, the incident originated at 1:14 a.m. on the 4th, the leakage occurred at the connecting hose between Ningbo Tiantong 1 × ship and the wharf where Fujian Donggang Petrochemical Industry Co., Ltd. carried out the C-9 shipment, resulting in a total of 6.97 tons of C-9 leakage.

According to the external report of Quanzhou Quangang District Environmental Protection Bureau, "it is due to the aging and damage of the gasket of the hose flange connected to the wharf by the tanker, resulting in the leakage of some oil products". After the leakage of carbon IX, Quangang District immediately launched the emergency plan for environmental emergencies, established working groups for on-site disposal, mass work, marine impact, incident investigation, etc., and rapidly carried out the emergency disposal work. As of 18:00 on April 4, the clean-up work of the carbon nine leakage sea area has been basically completed.

Uncover the secrets of carbon 9

What's the 'culprit' of this event, C9? Wu Lixin, a researcher, told reporters that C9 is a kind of polymer mixture, which is obtained by condensing the distillates containing nine carbon atom aromatics in the by-products of petroleum catalytic reforming and cracking in the presence of acid catalyst, mainly including trimethylbenzene, cumene, n-propylbenzene, ethyl toluene, etc.

Due to smelling the peculiar smell in the air, the local villagers are worried that the inhalation of volatile organic compounds in the air will affect their health. For this problem, Wu Lixin told reporters, C9 is a flammable dangerous product, which can cause pollution to the water, soil and atmosphere; it has anesthesia and stimulation effects. Inhalation and exposure to high concentration of this product steam has anesthesia and stimulation effects, which will cause eye, nose and throat And lung stimulation, headache, dizziness and other central nerve and upper respiratory tract irritation symptoms, long-term repeated contact can cause skin degreasing; at the same time, eating animal and plant seafood polluted by carbon 9, there are risks of poisoning, cancer and so on.

How should individuals protect

So, what are the protective measures for the villagers living near the carbon nine leakage area? Zheng Huidong, deputy dean of the school of petroleum and chemical engineering of Fuzhou University, reminded that if the residence is close to the leakage location, it is necessary to wear a mask containing activated carbon filter to avoid inhalation risk; to avoid eating contaminated animal and plant seafood, once eaten by mistake, rinse your mouth immediately and find abnormal feelings of lips, mouths and tongues Or numbness, accompanied by headache and dizziness symptoms, should be timely medical treatment; if skin, clothing contact, first wash with water, then wash thoroughly with detergent, soap and seek medical treatment.

Chen kaihan, senior experimenter of Quanzhou Normal University, said that although the water quality is up to standard, the problem of enrichment of the leaking part should not be underestimated. First, the leaking carbon nine may flow to stagnant water areas such as coast, reef and breeding area; second, it may be attached to seaweed, fish, soil and seabird; finally, it may also accumulate into animal oil and liver. Therefore, sea area management is a long-term and systematic work.

According to the relevant person in charge of Quangang agriculture, forestry and Water Bureau, the Bureau has issued an emergency notice on 4 days, asking to suspend the arrest, sale and consumption of aquatic products in the area of Xiaocuo village, reminding the general public to suspend the arrest, sale and consumption of marine products in the area, and whether they can be eaten will be tested by the authority. At the same time, the Environmental Protection Bureau of Quangang District also reported that at present, the investigation of the incident has been carried out in an all-round way, and professional organizations have been entrusted to carry out sampling and testing of water quality and seafood, and all relevant departments have made every effort to do relevant work according to their respective functions, so as to ensure that the incident is handled safely according to laws and regulations;
