Yintoni ekufuneka siyazi malunga nekhompawundi enetyhefu: Dibutyltin
Ikhemikhali eyityhefu, i-dibutyltin ekwizinto ezininzi ozisebenzisa yonke imihla. Luhlobo lwe-organotin ehlanganiswe ne-tin, i-carbon kunye ne-hydrogen. Isetyenziselwa ukuveliswa kwezinto ezibangela ushishino, izinzisi kunye nee-biocides ukuze zisetyenziswe kumacandelo amaninzi. Njengomphumo wolu setyenziso lubanzi, i-dibutyltin ifunyenwe (njengentsalela ye-metabolic) kwi-eco-system kunye newebhu yokutya kunye ne-bio-eye yaqokelelwa zizidalwa eziphakamisa inkxalabo yezempilo kwimpilo yabantu.
I-Dibutyltin yaziwa kakhulu ngeempembelelo zayo eziyityhefu kwizinto eziphilayo kunye nokusingqongileyo. Impembelelo yokusingqongileyo ye-dibutyltin ifundwe ngenxa yeziphumo zayo ezininzi ezimbi ezifana nokusebenza njengesiphazamisi se-endocrine esibeka umngcipheko kwizidalwa zasemanzini, abantu kunye nezilwanyana. I-Dibutyltin ifunxwa zizityalo kunye nezilwanyana xa ingena kwindawo yazo, ebangela ukuba imichiza iqokelele kwizinto zezityalo okanye izicubu zezilwanyana. Ngokomzekelo, i-dibutyltin ifunyenwe ibangela ukukhubazeka kunye nokunciphisa ukusebenza kwamaqanda kwizilwanyana ezihlala emanzini (i-oyster okanye i-shrimp) edlala indima ebalulekileyo kwisiseko se-webs yokutya kwamanzi.
I-Dibutyltin isetyenziswa kumashishini amaninzi kwaye inokungena kwiityathanga zokutya kunye nokukhusela okude kakhulu kokuvezwa komntu. I-Dibutyltin inokubakho kwiintlanzi, i-shellfish kunye nezinye izilwanyana zasemanzini ezidliwa ngabantu. Iikhemikhali zinokuba neempembelelo ezingalunganga ezahlukeneyo kwimpilo yabantu, ngakumbi ukuba ziza kumanqanaba aphezulu ukusuka ekusetyenzisweni kwezilwanyana zaselwandle ezifana nokungahambi kakuhle kophuhliso, ukuphazamiseka kwe-endocrine kunye noxinzelelo lomzimba. Ngaphaya koko, i-dibutyltin inokubakho kwindawo ephantsi nakwinyama evela kwizilwanyana ezingavezwanga ngqo kuyo.
Ikwasetyenziswa kumashishini ahlukeneyo njengesizinzisi, i-catalyst kunye ne-biocide umzekelo iipeyinti, iiplastiki kunye namalaphu. Kodwa ngenxa yetyhefu kunye neengxaki zempilo eziza nayo, abaphandi basebenzela ukufumana ezinye iikhemikhali ezinokuthi zithathe indawo ye-dibutyltin kwezi ntlobo. Ezinye iindlela eziphantsi kophando ziquka izizinzisi zezinto eziphilayo, ii-biocides kunye ne-catalysts ezibeka ingozi encinane kwindalo kunye nempilo yabantu.
I-Dibutyltin ibekelwe imiqathango engqongqo ngakumbi ukuze isetyenziswe kwaye ikhutshwe kumacandelo amaninzi amashishini ngamanyathelo olawulo. IManyano yaseYurophu, umzekelo, yanqanda i-dibutyltin kwiipeyinti ezichasene nokungcola kwaselwandle kwangoko ngo-2003 ngenxa yeempembelelo zayo eziyingozi kwizinto eziphilayo zasemanzini. Amanye amazwe angakumbi aye avala ukusetyenziswa kwe-dibutyltin, kwaye kukho iintshukumo eziqhubekayo zokuyenza lukhuni le migaqo. Ngokugqibeleleyo, kubalulekile ukujonga ezinye iindlela ezingeyongozi kwaye zikhuselekile ze-dibutyltin kuba iziphumo zayo eziyityhefu kwindalo kunye nempilo yabantu zinokuqhubeka kude kube kwixesha elizayo.
