E boetse e tsejoa e le chloroethylene, ethylene monochloride, kapa monochloroethylene, vinyl chloride ke khase e khanyang e ka chesang kapa e nang le metsi a monko o monate o monate. Vinyl chloride ke sehlahisoa se entsoeng ke batho. Ha e hlahe ka tlhaho tikolohong.
Lisebelisoa
Ho fihlela bohareng ba mashome a supileng a metso e supileng, vinyl chloride e ne e sebelisoa mefuteng e sa tšoaneng ea bareki, ho kenyelletsa litlolo, e le sekheo sa makotikoti a aososol, 'me e le se pholileng.
Kajeno, vinyl chloride e atisa ho sebelisoa ho etsa polymer e bitsoang polyvinyl chloride (PVC). PVC e fumanoa lihlahisoa tse sa tšoaneng tsa polasetiki, tse kenyelletsoang ho kenya mohala le ho kenya liphahlo.
Vinyl chloride e boetse e sebelisoa ha ho etsoa lihlatso tsa sakerete.
Kamoo Vinyl Chloride e Kenyang 'Meleng oa Motho
Hangata li-vinyl chloride li kenella 'meleng oa motho ka ho phalla:
- Moea o phefumolohang o haufi le libaka tse kotsi tse senyehileng / libaka tsa marulelo moo liindasteri tsa lipolitiki li lahlang lihlahisoa tsa litšila.
- Ho phatlolla moea sebakeng sa ho sebetsa se silafalitsoeng moo li-plastiki li hlahisoang kapa li sebelisoa.
- Ho tsuba sakerete kapa mosi oa cigar.
Ntho e sa tloaelehang, vinyl chloride e ka kenngoa ha motho a noa metsi a tsoang selibeng se silafetseng.
Vinyl Chloride ka cigarettes
Li-vinyl chloride li ka fumanoa mosi ka bobeli le ka mosi oa mosi oa mofuta o tlase, ka tloaelo ho na le li-nanogram tse 5 ho isa ho tse 30 ka sakerete (nanogram ke 0.000000001 gram).
Liphuputso tsa nako e telele tsa ho pepesehela vinyl chloride liphoofolong li bontšitse hore kankere ea sebete le lesela la mammary le ka eketseha ha maemo a tlaase a vinyl chloride a teng moeeng (50 ppm).
Le hoja re sa tsebe hore na mosi oa sakerete o kenngoeng ka hare-hare o hloka eng ho bontša likotsi tsa bophelo bo botle ba vinyl chloride, rea tseba hore e tlatsetsa kankere ebile ha e kotsi ho phefumoloha ka bongata.
Likotsi tsa Bophelo
Likotsi tsa bophelo tsa ho pepesehela vinyl chloride li itšetlehile ka lintlha tse 'maloa:
- Chelete eo motho eo a ileng ae pepesa.
- Nako le nako ea ho pepeseha.
- Bolelele ba ponahalo e 'ngoe le e' ngoe.
- Mofuta oa ho pepesa; ho inhalation kapa ho kenngoa ha lijo.
Lintlha tse ling tse lokelang ho nkoa li kenyeletsa hore na ho ne ho e-na le lik'hemik'hale tse ling tse teng nakong ea ho pepesa vinyl chloride, hammoho le lilemo, thobalano, lijo le bophelo bo botle ba motho ea hlalositsoeng.
Ha vinyl chloride e kenella maling, e ea sebeteng, moo e fetohang lintho tse ling.
Vinyl kloride ka boeona e siea 'mele ka hare ho letsatsi ka motsoako, empa lintho tse hlahisoang sebeteng li nka nako e telele ho tsoa' meleng. Tse ling tsa tsona li kotsi ho bophelo ba batho ho feta vinyl chloride hobane li itšoara ka lik'hemik'hale tse tloaelehileng 'meleng' me li fetola kamoo li sebelisetsoang kateng / li arabelloa ke physiologically.
Vinyl Chloride le Kankere
Vinyl chloride e ka eketsa monyetla oa ho hlahisa likarolo tse ngata tsa kankere, ho akarelletsa:
- Kankere ea sebete
- Kankere ea boko
- Kankere ea molomo
- Lymphoma
- Lefuemia
US Dept. ea Bophelo le Litšebeletso tsa Botho, Mokhatlo oa Machaba oa Lipatlisiso ka Kankere, le US Environmental Production Agency kaofela ba hlokometse vinyl chloride e le lefu la motho le tsebahalang.
Ho Eketsehileng ho Lik'hemik'hale ka Mosi oa Sirena
Ho fihlela joale, lipatlisiso li senole lik'hemik'hale tse fetang 7 000, tse kenyelletsang lik'hemik'hale tse 250 tse chefo le tse 70 tse nang le mosi oa sakerete, 'me ntle ho pelaelo li senola ho hongata nakong e tlang.
Haeba o ntse o tsuba, ka kopo qala ka leeto le pholosang bophelo ba ho khaotsa ho tsuba . U se ke ua lieha. Qala ka lenaneo la hau la ho tlohela hona joale. U ke ke ua ikoahlaea.
