Ngokwedatha yamva nje yezerhafu, indlela eTshayina yorhwebo lwe-dichloromethane (DCM) kunye ne-tricchloromethane (TCM) ngoFebruwari 2025 kunye neenyanga ezimbini zokuqala zonyaka zityhile iindlela ezahlukeneyo, ezibonisa utshintsho kwimfuno yehlabathi kunye namandla emveliso yasekhaya.
I-Dichloromethane: Ukuthunyelwa kwamanye amazwe kukhokelela ekukhuleni
NgoFebruwari 2025, iTshayina ingenise iitoni eziyi-9.3 ze-dichloromethane, nto leyo ebonakalisa ukunyuka okumangalisayo kwe-194.2% unyaka nonyaka. Nangona kunjalo, ukungeniswa okuqokelelweyo ngoJanuwari-Februwari 2025 kufikelele kwiitoni ezingama-24.0, kwehle ngama-64.3% xa kuthelekiswa nexesha elifanayo ngo-2024.
Ukuthunyelwa kwamanye amazwe kuthethe ibali elahlukileyo. UFebruwari ubone iitoni ezili-16,793.1 zeDCM ezithunyelwe kwamanye amazwe, ukunyuka kwe-74.9% unyaka nonyaka, ngelixa ukuthunyelwa kwamanye amazwe okuqokelelweyo kwiinyanga ezimbini zokuqala kufikelele kwiitoni ezingama-31,716.3, ukunyuka nge-34.0%. UMzantsi Korea uphume phambili ngoFebruwari, ungenisa iitoni ezingama-3,131.9 (18.6% yezo zizonke ezithunyelwa kwamanye amazwe), kulandelwa yiTurkey (1,675.9 iitoni, 10.0%) kunye ne-Indonesia (1,658.3 iitoni, 9.9%). Ukususela ngoJanuwari ukuya kuFebruwari, uMzantsi Korea ugcine ukhokelo lwayo ngeetoni ezingama-3,191.9 (10.1%), ngelixa iNigeria (2,672.7 iitoni, 8.4%) kunye ne-Indonesia (2,642.3 iitoni, 8.3%) zinyuke kakhulu.
Ukunyuka okukhulu kokuthunyelwa kwamanye amazwe kwe-DCM kugxininisa ukwanda kwamandla emveliso yaseTshayina kunye namaxabiso akhuphisanayo kwimarike yehlabathi, ngakumbi kwizinyibilikisi zoshishino kunye nokusetyenziswa kwamayeza. Abahlalutyi bathi ukukhula oku kubangelwa kukwanda kwemfuno evela kuqoqosho olusakhulayo kunye nohlengahlengiso lwekhonkco lokubonelela kwiimarike eziphambili zaseAsia.
I-Trichloromethane: Ukuthunyelwa Kwempahla Kuyehla Kuqaqambisa Imingeni Yemarike
Urhwebo lweTrichloromethane lubonise umfanekiso obuthathaka. NgoFebruwari 2025, iTshayina ingenise iitoni ze-TCM ezingaphantsi kwe-0.004, ngelixa ukuthunyelwa kwamanye amazwe kwehle ngama-62.3% unyaka nonyaka ukuya kwiitoni ezingama-40.0. Ukuthunyelwa kwamanye amazwe okuqokelelweyo ngoJanuwari-Februwari kufane nale ndlela, kwehle nge-100.0% ukuya kwiitoni ezingama-0.004, apho ukuthunyelwa kwamanye amazwe kwehle ngama-33.8% ukuya kwiitoni ezingama-340.9.
UMzantsi Korea ulawula ukuthunyelwa kwe-TCM kumazwe angaphandle, uthatha i-100.0% yempahla ethunyelweyo ngoFebruwari (iitoni ezingama-40.0) kunye ne-81.0% (iitoni ezingama-276.1) kwiinyanga ezimbini zokuqala. IArgentina neBrazil nganye ithathe i-7.0% (iitoni ezingama-24.0) yexabiso lilonke ngoJanuwari-Februwari.
Ukwehla kokuthunyelwa kwe-TCM kwamanye amazwe kubonisa ukwehla kwemfuno yehlabathi, okunokunxulunyaniswa nemithetho yokusingqongileyo ephelisa ukusetyenziswa kwayo kwiifriji kunye nolawulo olungqongqo kwizicelo ezinxulumene ne-chlorofluorocarbon (CFC). Ababukeli beli shishini baqaphela ukuba ukugxila kweTshayina kwiindlela eziluhlaza kunokuthintela ngakumbi imveliso kunye norhwebo lwe-TCM kwixesha eliphakathi.
Iziphumo zeMarike
Iindlela ezahlukeneyo ze-DCM kunye ne-TCM zibonisa iindlela ezibanzi kwicandelo leekhemikhali. Nangona i-DCM izuza kubuchule bayo bokuvelisa kunye nezinyibilikisi, i-TCM ijongene neengxaki ngenxa yoxinzelelo lokuzinza. Indima yeTshayina njengomthumeli omkhulu we-DCM isenokuqina, kodwa usetyenziso olukhethekileyo lwe-TCM lunokubona ukuhla okuqhubekayo ngaphandle kokuba kuvele ukusetyenziswa okutsha kwemizi-mveliso.
Abathengi behlabathi, ngakumbi e-Asia nase-Afrika, kulindeleke ukuba baxhomekeke ngakumbi kwiimveliso zaseTshayina ze-DCM, ngelixa iimarike ze-TCM zinokutshintshela kubavelisi beekhemikhali ezikhethekileyo okanye kwimimandla enemigaqo-nkqubo yokusingqongileyo engqongqo kangako.
