Tsis ntev los no, tus nqi ntawm cov khoom siv tshuaj lom neeg tau nce siab: Muaj ntau hom thiab ntau yam. Thaum Lub Yim Hli, tus nqi ntawm cov khoom siv tshuaj lom neeg tau pib nce siab. Ntawm 248 tus nqi khoom siv tshuaj lom neeg uas peb tau taug qab, 165 yam khoom tau nce tus nqi nrog qhov nruab nrab nce ntawm 29.0%, thiab tsuas yog 51 yam khoom poob tus nqi nrog qhov nruab nrab txo qis ntawm 9.2%. Ntawm lawv, tus nqi ntawm cov MDI ntshiab, butadiene, PC, DMF, styrene thiab lwm yam khoom tau nce siab heev.

Feem ntau qhov kev thov rau cov khoom siv tshuaj lom neeg muaj ob lub caij nyoog siab tshaj plaws, uas yog Lub Peb Hlis-Plaub Hlis tom qab Lub Caij Nplooj Ntoos Hlav thiab Cuaj Hlis-Lub Kaum Hli hauv ib nrab xyoo tom ntej. Cov ntaub ntawv keeb kwm ntawm Tuam Tshoj Cov Khoom Siv Tshuaj Lom Zem (CCPI) txij li xyoo 2012 txog 2020 kuj lees paub txoj cai ntawm kev ua haujlwm ntawm kev lag luam no. Thiab zoo li lub xyoo no, cov nqi khoom tau txuas ntxiv nce txij li Lub Yim Hli, thiab nkag mus rau hauv ib xyoos ntawm kev txaus siab tsis tu ncua hauv Lub Kaum Ib Hlis, tsuas yog xyoo 2016 thiab 2017 tsav los ntawm kev hloov pauv sab kev muab khoom.

Tus nqi roj av ua lub luag haujlwm tseem ceeb hauv kev nce nqi ntawm cov khoom siv tshuaj lom neeg. Feem ntau, tus nqi ntawm cov khoom siv tshuaj lom neeg feem ntau nce thiab nqis raws li kev hloov pauv ntawm tus nqi roj av. Txawm li cas los xij, thaum tus nqi nce ntawm cov khoom siv tshuaj lom neeg, tus nqi roj av tseem tsis hloov pauv, thiab tus nqi roj av tam sim no tseem qis dua li tus nqi thaum pib Lub Yim Hli. Saib rov qab rau 9 xyoo dhau los, tus nqi ntawm cov khoom siv tshuaj lom neeg thiab roj av tau hloov pauv ntau tsuas yog 5 zaug, feem ntau yog thaum lub sijhawm siab tshaj plaws lossis qis tshaj plaws, thiab tus nqi roj av tau nce thaum tus nqi ntawm cov khoom siv tshuaj lom neeg tseem nyob ruaj khov lossis qis dua. Tsuas yog xyoo no tus nqi ntawm cov khoom siv tshuaj lom neeg nce siab heev, thaum tus nqi ntawm cov roj av hloov pauv. Nyob rau hauv cov xwm txheej zoo li no, kev nce nqi ntawm cov khoom siv tshuaj lom neeg feem ntau tau ua rau cov txiaj ntsig ntawm cov tuam txhab cuam tshuam nce ntxiv.

Cov tuam txhab tshuaj lom neeg feem ntau yog ib qho ntawm cov kev sib txuas hauv cov saw hlau kev lag luam, thiab feem ntau ntawm lawv cov khoom lag luam sab saud lossis cov neeg siv khoom kuj yog cov tuam txhab tshuaj lom neeg. Yog li ntawd, thaum tus nqi khoom ntawm lub tuam txhab A nce siab, tus nqi ntawm lub tuam txhab B, uas yog lub tuam txhab sab saud, kuj yuav nce siab. Thaum ntsib qhov xwm txheej no, lub tuam txhab B txiav kev tsim khoom lossis ncua kev tsim khoom kom txo kev yuav khoom, lossis nce tus nqi ntawm nws cov khoom kom hloov pauv qhov kev nyuaj siab ntawm cov nqi nce siab. Yog li ntawd, seb tus nqi ntawm cov khoom lag luam sab saud puas tuaj yeem nce siab yog lub hauv paus tseem ceeb rau kev txiav txim siab qhov kev ruaj khov ntawm tus nqi nce siab ntawm cov khoom lag luam tshuaj lom neeg. Tam sim no, hauv ntau cov saw hlau kev lag luam, tus nqi ntawm cov khoom lag luam tshuaj lom neeg tau pib kis mus zoo.

Piv txwv li, tus nqi ntawm bisphenol A tsav tus nqi ntawm PC nce, silicon hlau tsav tus nqi ntawm cov organic silicon, uas tsav tus nqi ntawm cov roj hmab sib xyaw thiab lwm yam khoom, tus nqi ntawm adipic acid tsav tus nqi ntawm slurry thiab PA66, thiab tus nqi ntawm cov MDI ntshiab thiab PTMEG tsav tus nqi ntawm spandex.

Ntawm 248 tus nqi khoom tshuaj uas peb tau taug qab, muaj 116 tus nqi khoom tseem qis dua tus nqi ua ntej muaj kev sib kis; piv rau lub sijhawm tib yam xyoo tas los, muaj 125 tus nqi khoom qis dua lub sijhawm tib yam xyoo tas los. Peb siv tus nqi nruab nrab ntawm cov khoom hauv xyoo 2016-2019 ua tus nqi nruab nrab, thiab muaj 140 tus nqi khoom tseem qis dua tus nqi nruab nrab. Tib lub sijhawm, ntawm 54 tus nqi khoom tshuaj uas peb tau taug qab, muaj 21 tus nqi tseem qis dua tus nqi ua ntej muaj kev sib kis; yog tias piv rau lub sijhawm tib yam xyoo tas los, muaj 22 tus nqi khoom qis dua lub sijhawm tib yam xyoo tas los. Peb siv tus nqi khoom nruab nrab xyoo 2016-2019 ua tus nqi nruab nrab, thiab muaj 27 tus nqi khoom tseem qis dua tus nqi nruab nrab. Qhov no sib xws nrog cov ntaub ntawv PPI txhua xyoo thiab txhua peb lub hlis.
