Cov ntsiab lus cov ntsiab lus
Kev ntsuas ntawm polycyclic aromatic hydromatic hydom nrho hauv kev tshaj tawm xov xwm thiab TV suav nrog kev sab laj PAH, kev tshuaj ntsuam Rawnising, thiab kuaj cov khoom tiav ua tiav, thiab kev sim cov khoom tiav tiav thiab cov khoom tiav.
Kev sim ntawm polycyclic aromatic hydrocarbons (PAHS) feem ntau yog kuaj pom cov ntsiab lus zoo xws li Benzene, pyracenese, pyrenee, thiab Benzo [a].

Kev ntsuas cov khoom nyoos ua voj voog: 5 hnub ua haujlwm. Rau cov khoom tiav, thov sab laj nrog cov neeg siv khoom ntawm lub khw.
Kev Pabcuam Tom Qab
Polycyclic aromatic hydrocarbons (PAHS) yog ib lo lus dav dav rau chav kawm ntawm cov duab uas muaj ntxhiab, feem ntau yog muab los ntawm cov seem hauv Tar refining. Lawv muaj nyob hauv cov roj petrochemical xws li cov roj nyoos, cov roj captant, cov roj av hluav taws xob, cov roj av roj av, asphalt, thiab tseem muaj cov khoom lag luam txhua hnub xws li Raws li tshuaj tua kab, hluav ncaig, cov yoov tshaj cum, feem ntau cov khoom muaj cov khoom siv log roj hmab, feem ntau yuav muaj cov khoom siv log tsheb ntau dua, yuav muaj theem siab ntawm PAHS. Polycyclic aromatic hydrocarbons muaj carcinogenic, mutagenic, thiab kev ua me nyuam system cov khoom siv tshuaj lom.
