An incident that the rare job is poisoned

An incident that the rare job is poisoned

Incident: Strange patient
Since January of 2007, occupational disease of Beijing Chaoyang hospital and poisoning in the medical department and accepting 7 strange patients for medical treatment successively. They all come from a printing factory in Hebei, and work in the same workshop.
"These patients are all under the condition that the local hospital treatment came to naught, through hold a consultation, come the intersection of we and the intersection of hospital and treatment. " Occupational disease of Beijing Chaoyang hospital and poisoning medical head of the department Hao FengTong and introducing, "check to find, all patients have more or less thoraxes to accumulate the liquid, the lung fiber appears to a certain degree on later stage, such a clinical case is rare, previous we have not met. "
7 workshops of printing factory which female workers belong to, the main task is to carry on PS edition and gush out and spread the color. For this reason, they want to use several kilograms of coating per person per day, the machine utilizes the pressure to turn the liquid coating into aerosol, gush out and apply to PS edition. So, give out the dense " similar paint " in the air Taste.
According to the report of the media, that year, the factory received a form business, coloured for lucite of about 5000 square meters, the printing factory has gone to Tianjin to specially purchase a batch of coating. Soon, these female workers' cheek, neck begin to present erythema of the petal of the Chinese rose. No one took notice of at that time, about half a year later, they began the asthma uncomfortable in chest, and more and more serious. In the local hospital, they are diagnosed as " pulmonary tuberculosis " ,However, there is not any result in the treatment to the ill.
Toss about in bed, come the intersection of Beijing and Chaoyang behind the hospital, when being admitted to hospital and checked, the doctors find these female workers damage the lung at various degrees. The ones that study in image check more ocular: The chest X-ray examination and CT checks to find, all female workers have thoraxes to store up the liquid, some female workers among them have pericardiums to store up pathological change of the quality among the liquid and lung at various degrees.
18 months later, 2 female workers successively died.
Investigate: Terrible workshop
In order to clear up 7 female worker's ill truth, another respiratory medicine doctor of Hao FengTong and hospital specially goes to Chengde, carry on the on-the-spot investigation.
When getting to the printing factory, Hao FengTong finds in surprise, the primary condition not in accordance with production operation of place that these female workers work. This is the workshop transformed in a storehouse, without a window, only a door suitable for coming in and going out. In addition ventilation of workshop arrange dust facility even broken, and there is maintenance. Professional sensitiveness let the intersection of phoenix and general term for paulownia, phoenix tree and tung tree Hao realize in female worker intensive winter, spring when have illness coming on still, because the open air is colder, the only gate that can make the air circulate is basically turned off.
"This means, has noxious substances in the environment, can not almost be ventilated, equal to causing the contamination mode under a kind of close toxicological environment artificially. " Therefore the intersection of phoenix and general term for paulownia, phoenix tree and tung tree Hao assert, this close workshop is causing 7 female worker infected " killers " .
Then, " poisonous " Where does the source come from? It is numerous to engaged in printing the enterprises of the homework of spraying of PS edition both at home and abroad, has not found yet that there are similar situations. Hao FengTong checks mixture of sour ester of raw materials polypropylene of spraying in the course of arranging checking, find this batch of coating bought from Tianjin is typical " Have no products three times " : There is no name of product to annotate, chemical composition does not prove, there is no information of place of production.
In order to further prove that the result is inferred, the doctors trust the medical laboratory, test toxicity to the big mouse contaminating, symptom that the big mouse appears as people quickly, also the obvious thorax appears to accumulate the liquid.
As to this, the intersection of phoenix and general term for paulownia, phoenix tree and tung tree Hao draw the preliminary conclusion: "7 female workers work in the same printing factory and a workshop, there is not a protective measure too, contacted the same products, time exceeds 5 months, later similar symptom appeared, accumulate the liquid as the important characteristic with the thorax, and the lung fiber appears. So can infer out 7 female worker's ill important factors, first, the coating products have problems, second, close some noxious substance high density under the environment. "
Difficult problem: The permanent lung is damaged
19 more -year-old by spring such as king such as female worker ' Assumed name) On later stage treating, it is being very frequent that water of chest is being punctured. In order to lighten the agony that is punctured repeatedly, the doctor decides to hold the emulsion hose up in her thorax, it is convenient to guide regularly.
However, all medical means can not prevent the fiber process of lung from accelerating. 18 months later, Wang ChunXin's lung function is nearly lost, " the whole thorax is become the cubicle one by one by the parcel, want to be got through into a large ' the room ' to be very difficult, basically at a loss what to do. " Finally, because Wang Chun breathes the depleted death.
To 5 female workers that also alive now, though their life can be paid by oneself, but labour capacity has been basically lost. After 2 years, they, to curing and still holding the hope, before Hao FengTong remembers 4 months, and female workers make telephone consultation.
Nowadays, the medical subject and printing factory are still keeping in touch with poisoning occupational disease of Chaoyang hospital of Beijing. Hao FengTong reveals to the reporter, 2 months ago, this printing factory returns the incoming telegram to inquire whether there is the new way that treats female workers.
The doctor participating in treating and curing has not got yet so far " Cause trouble " This batch original for material prescription,cannot last compositions concrete, for one of regrets.
Expect: The occupational environment needs to strengthen and supervise
"I think, it causes the ignoring of workplace environmental security of the job for a long time that the tragedy happens in this. " The intersection of phoenix and general term for paulownia, phoenix tree and tung tree Hao appeal for setting up more effective job supervisory system, devotes more efforts to supervising to enterprise's production environment.
In June of this year, the figure that the intersection of National Federation of Trade Unions and labour protection department is announced reveals, China has already exposed to the critically ill the total number of person which hurt the factor of jobing exceeded 200 million. On the other hand, a lot of homework workers are not included in guarding.
The expert points out this incident while reviewing, so long as any link operates normally, these 7 female workers might not contaminate. For example the printing factory repacks the warehouse into the production scene, why not report to the related departments for approval? Machinery ventilation facilities can't run well, there are no windows in the production scene, why does anybody come to manage? Someone can " Ask, park " Do not conform to the enterprises of the rule?
The more awkward one is, occupational disease that these 7 female workers suffer from, it is unable to sort out so far. According to 10 big classes and 115 kinds of the legal " occupational disease catalogue ", 7 female workers' disease is all unable to " sit in the right seat " .
The background is understood - -
" nanometer causes a disease " Right and wrong
In 7 female worker's job poisoning, cause educational circles pay close attention to extensively, above-mentioned author, the intersection of Beijing and the intersection of Chaoyang and the intersection of hospital and occupational disease and poison medical YuGuo Song, doctor of department, get " nanometer disease " out of of thesis This concept. It is said, irritate lotion, water of chest and lung and find the particle with a diameter of 30 nanometers while living and examining organizing in these female workers' workplace, bronchus alveolus. Observe at mirrors electric,last skin in lung these particle with among and in qualities nuclear afterbirth thick liquid at cells leather.
Nanotechnology has already been applied to production fields of industry such as Aero-Space, military affairs, medical science, coating,etc. extensively. Song YuGuo calls upon in the thesis, the pathogenic phenomenon of nanometer must cause the attention of the medical circle.
The thesis to entitled as " the intersection of nanometer and contact and thorax of particle accumulate liquid, the intersection of quality and the intersection of fiber and take, the intersection of granulation and swollen relevance among the lung ", have caused the dispute of the educational circles, has brought this incident into the public visual field. British Nature thinks, this is that the nanometer particle of the record causes the research thesis of the human disease for the first time, dispute and add fuel to the flames for the health risk of relevant nanotechnology at the same time.
As to this, relevant experts think " nanometer disease " Formulation not proper,if you can't is there expert too, query last the occupational disease for nanometer particle. The square loyal professor of the physical researcher of research institute of Chinese Academy of Sciences thinks, speaking from the physics meaning, the volume of the nanometer particle is really smaller than the cell membrane, the possibility entered exists. But to its ability of movement, penetrate the affirmation of ability, need more evidences.
U.S.A. environmental protection association health problem chief scientist John and Barr and Booth points out, even if the nanometer particle has the ability to enter our health, reach the position where the general chemical material can't be reached, think it is groundless too that the nanometer particle has idea endangered. Environment and job medical expert's Sidon of breath toxicologist Donaldson of British Edinburgh University and Britain Aberdeen university hold the suspicious attitude to this. According to existing evidence can't think the intersection of identification and the intersection of nanometer and particle and causality between the disease only by they, should consider the intersection of homework and environment, possible job before the patient expose factor,etc..
In fact, since nanotechnology is after born in latter stage of the eighties of last century, the dispute about influencing the health in this new science and technology has never been stopped. In the field of nanometer, a lot of classical formulae are no longer applicable, novel characteristic and function of the material structure display. Have and study and claim, some nanometers of particles that project science makes recently may initiate cancer. For example, carbon nanotube, nanometer oxidize nanometer material thinking to cause animal's lung to be dirty, liver, kidney and blood system such as titanium to damage two times.
