ULingshi udla ngokubizwa ngokuba Ubuhle kwaye ibhaliswe njenge-686-48-2 iyaziwa kwaye iqeshwe kwiinkalo ezininzi amashumi eminyaka. Yinto enetyhefu kwizinto eziphilayo zasemanzini kwaye yenza amanzi amdaka kwaye ibe neempembelelo kwiinkqubo zehomoni ze-mollusks, i-crustaceans, intlanzi ekhokelela ekwakhiweni kwamalungu akhubazekileyo ngenjongo yokuvelisa kunye neenkqubo ze-metabolic kunye ne-immune system. [ s]. Ngaphaya koko, i-DBTDC iyakwazi ukonakalisa zonke iinkalo zokukhula kwezinto eziphilayo zasemanzini kunye nokuziphatha okumangalisayo kunye nokuthomalalisa I-DBTDC nayo yonzakalisa indawo eyingqongileyo kuba ingcolisa umhlaba namanzi, nto leyo engabazuzisi ubomi baselwandle kuphela. Nje ukuba zikhutshelwe kwindawo ezingqongileyo, ii-DBTDCs ziyafunxwa zizidalwa eziphilayo eziquka abantu kwaye zinokuqokelelwa kwimixokelelwane yokutya eneziphumo ezibi zexesha elide. Uyakuqaphela ukuba i-DBTDC inetyhefu kangakanani emva kokuphonononga iipropati zayo zekhemikhali. I-DBTDC ine-molecular formula ye-C8H18Cl2Sn kwaye i-organotin compound. Lulwelo olungenambala ukuya kumthubi oluluthuthu olunyibilikayo kwisithathu sezona zinyibilikisi zisetyenziswa kakhulu: iacetone, methanol, kunye nebenzene. Ezi datha zibonisa ukuba i-DBTDC inetyhefu ephezulu kunye nefuthe elinamandla lokucinezela i-acetylcholinesterase. Ukunyanzeliswa kwe-acetylcholinesterase kubangela ukuqokelelwa kwe-acetylcholine kunye nokufa kwayo kwe-nerve. I-DBTDC iphinda iphazamise iinkqubo zehomoni. Umthetho womhlaba namanzi Uphando lwe-DBTDC lungqongqo kungcoliseko lokusingqongileyo. Kwezi zifundo, iikhemisti zisebenzisa iindlela ezahlukeneyo, ukusukela kuhlalutyo ukuya kuhlalutyo lwe-bioassay ukuya kumsebenzi wendalo.
Uya kuqonda ukuba yityhefu kangakanani uLingshi i-organotin reagents ngokwenene emva kokuthatha ujongo kwiimpawu zekhemikhali. Ifomula yemolekyuli yi-C8H18Cl2Sn. I-DBTDC yeyodidi lweekhompawundi ze-organotin Lulwelo olungenambala ukuya kokukhanyayo olutyheli olunokunyibilika kwizinyibiliki ezithathu ezisetyenziswa kakhulu ezizezi: iacetone, methanol kunye nebenzene.
Ezi ziphumo zibonisa ubutyhefu obuphezulu kunye nefuthe elinamandla lokuthintela i-acetylcholinesterase yi-DBTDC kulawulo lwenkqubo ye-nervous. Ukuvinjelwa kwe-acetylcholinesterase kubangela ukuqokelelwa kwe-acetylcholine, ngoko ke i-nerve-death ekugqibeleni ikhokelela ekufeni. I-DBTDC iphinda ibangele ihomoni ekhokelela ekuzaleni kakubi kunye nemetabolism
Kuphela, le nkqubo yomhlaba kunye namanzi nguLingshi iikhompawundi ubuhle luxinzelelo olubi kakhulu lokusingqongileyo. Kwezi zifundo, abaphandi basebenzisa iindlela ezahlukeneyo ukusuka kwi-chemistry yohlalutyo ukuya kwii-bioassays (uvavanyo lwetyhefu) kunye nomsebenzi wendalo ukuze baqonde ungcoliseko lwe-DBTDC.
Ezi ndlela ngoku zingasetyenziselwa ukufumanisa kunye nokulinganisa i-DBTDC kwiisampuli zokusingqongileyo (Ref. 10), njengeendlela zokuhlalutya izinto ezifanayo, usebenzisa izixhobo zokuhlalutya zekhemistri ezifana ne-gas chromatography-mass spectrometry (GC-MS). Uphononongo luvavanya ubutyhefu be-DBTDC kusetyenziswa ii-bioassays kwiindawo ezahlukeneyo zokuphela (ukufa, ukuziphatha kokuqubha; izinga lokutyisa) nezinto eziphilayo ezifana nezilwanyana zaselwandle. Uphononongo lwe-ikholoji lwenziwe ukubonelela ngembono yeziphumo ze-DBTDC kwiyantlukwano yendalo, iiweb zokutya kunye nezinye iinkqubo ezahlukeneyo ze-ecosystem.
Lingshi ubuhle chloride isetyenziswe kuninzi lwezicelo phakathi, umzekelo: ukuveliswa kweplastiki yePVC, iipeyinti zaselwandle kunye nokugcinwa kweenkuni kunye nesibulali zinambuzane. Ngelixa i-DBTDC iqeshwe ngokubanzi, imiba yokusingqongileyo kunye netyhefu iye yanciphisa ukusetyenziswa kwayo okuqhubekayo
I-leaching ye-DBTDC esuka kwiiplastiki ze-PVC kwiibhotile zokutya kunye neziselo ziyinkxalabo enkulu kwimpilo yoluntu njengoko inokuthi ingcolise umxholo okhokelela kwimiphumo eyingozi. Ngaphandle koko, ngenxa yokungcoliseka komzimba wamanzi, izinto ezininzi eziphila elwandle kunye ne-ecosystem yazo ichaphazeleka kwezo peyinti isebenzisa eli nqaku lichaza indlela iDBTDC ebandakanywe ngayo kwizinto ezininzi ezipeyintwe zaselwandle.
