Uphando olutsha oluvela kwiDyunivesithi yase-Iowa lubonisa ukuba abantu abanamanqanaba aphezulu ekhemikhali ethile emizimbeni yabo, ebonisa ukuchanabeka kwizibulali-zinambuzane ezisetyenziswa ngokuqhelekileyo, kusenokwenzeka ukuba babulawe sisifo sentliziyo.
Iziphumo, ezipapashwe kwi-JAMA Internal Medicine, zibonisa ukuba abantu abanamazinga aphezulu okuvezwa kwi-pyrethroid pesticides bancinci ngokuphindwe kathathu ukuba bafe ngenxa yesifo senhliziyo kunabantu abanamazinga aphantsi okuvezwa okanye abangenalo ukuvezwa kwi-pyrethroid pesticides.
Iziphumo zivela kuhlalutyo lwesampulu emele ilizwe labantu abadala base-US, hayi nje abo basebenza kwezolimo, utshilo u-Wei Bao, unjingalwazi oncedisayo kwi-epidemiology kwiYunivesithi yase-Iowa yeSikolo seMpilo yoLuntu kunye nombhali wophononongo.Oku kuthetha ukuba iziphumo zineempembelelo kwimpilo yoluntu kuluntu luphela.
Ukwalumkise ngelithi ngenxa yokuba olu luphononongo loqwalaselo, alukwazi ukumisela ukuba ngaba abantu abakwisampulu basweleke ngenxa yokuvezwa ngokuthe ngqo kwipyrethroids.Iziphumo zibonisa ukuba kunokwenzeka ukuba kubekho ikhonkco, kodwa uphando olongezelelweyo luyafuneka ukuphindaphinda iziphumo kunye nokumisela indlela yezinto eziphilayo, wathi.
I-Pyrethroids iphakathi kwezona zibulala-zinambuzane zixhaphakileyo ngesabelo semarike, zibalelwa kuninzi lwezitshabalalisi zasekhaya zorhwebo.Zifumaneka kwiimpawu ezininzi zorhwebo zezinambuzane kwaye zisetyenziselwa kakhulu ukulawula izinambuzane kwiindawo zezolimo, uluntu kunye neendawo zokuhlala.I-Metabolites ye-pyrethroids, efana ne-3-phenoxybenzoic acid, inokufumaneka kumchamo wabantu abavezwe kwi-pyrethroids.
U-Bao kunye neqela lakhe lophando bahlalutya idatha kumanqanaba e-3-phenoxybenzoic acid kwiisampuli zomchamo ukusuka kwi-2,116 yabantu abadala abaneminyaka eyi-20 ubudala nangaphezulu abaye bathatha inxaxheba kwi-National Health and Nutrition Examination Survey phakathi kwe-1999 kunye ne-2002. Isampulu yedatha yafa ngo-2015 kwaye kutheni.
Baye bafumanisa ukuba ngaphezu kwexesha eliqhelekileyo lokulandelelana kweminyaka eyi-14, ngo-2015, abantu abanamazinga aphezulu e-3-phenoxybenzoic acid kwiisampuli zomchamo babengamaphesenti angama-56 amathuba okuba bafe ngenxa yaso nasiphi na isizathu kunabantu abanamaqondo aphantsi kakhulu.Isifo sentliziyo, ngoyena nobangela uphambili wokufa, sinokwenzeka ngokuphindwe kathathu.
Nangona uphononongo lukaBao aluzange lugqibe ukuba izifundo zibonakaliswe njani kwi-pyrethroids, uthe izifundo zangaphambili zibonise ukuba ukubonakaliswa kwe-pyrethroid kwenzeka ngokutya, njengoko abantu abatya iziqhamo kunye nemifuno efafazwe nge-pyrethroids baginya imichiza.Ukusetyenziswa kweepyrethroids ekulawuleni izinambuzane ezitshabalalisayo ezigadini nasemakhaya nako ngumthombo obalulekileyo wohlaselo.Iipyrethroids zikwakho kuthuli lwasekhaya apho ezi zibulali zinambuzane zisetyenziswa.
U-Bao uphawule ukuba isabelo semarike yezibulali-zinambuzane zepyrethroid sinyukile ukusuka kwixesha lophononongo lika-1999 ukuya ku-2002, nto leyo eyenza ukuba kunokwenzeka ukuba ukufa kwentliziyo nokunxulunyaniswa nokuba sesichengeni kwazo kunyuke.Nangona kunjalo, uphando olongezelelweyo luyafuneka ukuvavanya ukuba le ngcamango ichanekile, utshilo uBao.
Iphepha elithi, "Umbutho wokuvezwa kwi-pyrethroid insecticides kunye nobungozi bezinto zonke kunye nokufa kwabantu abadala base-US," yahlanganiswa nguBuyun Liu kunye noHans-Joachim Lemler weYunivesithi yase-Illinois School of Public Health., kunye noDerek Simonson, umfundi ophumelele kwiYunivesithi yase-Illinois kwi-toxicology yabantu.Ipapashwe nge-30 kaDisemba, i-2019 ye-JAMA yangaphakathi yezoNyango.
