Tsvagiridzo itsva kubva kuYunivhesiti yeIowa inoratidza kuti vanhu vane mwero wakakwira weimwe kemikari mumiviri yavo, zvichiratidza kusangana nemishonga inouraya zvipembenene inowanzoshandiswa, vane mukana wakakura wekufa nechirwere chemoyo.
Mhedzisiro, yakabudiswa muJAMA Internal Medicine, inoratidza kuti vanhu vane mazinga akakwirira ekubatwa nemishonga yepyrethroid vane mukana wakapetwa katatu kuti vafe nechirwere chemwoyo pane vanhu vane mazinga akaderera ekuratidzwa kana kuti vasina hutachiona hwepyrethroid pesticides.
Mhedzisiro yacho inobva mukuongororwa kwemuenzaniso wemumiriri wenyika wevakuru vekuUS, kwete chete avo vanoshanda mukurima, akadaro Wei Bao, mutevedzeri wepurofesa wechirwere chechirwere chechirwere chechirwere chechirwere paUniversity yeIowa Chikoro chePublic Health uye munyori wechidzidzo ichi.Izvi zvinoreva kuti mhedzisiro ine chekuita nehutano hweveruzhinji kuruzhinji rwevanhu.
Akayambirawo kuti nekuti ichi chidzidzo chekutarisa, hachigone kuona kana vanhu vari mumuenzaniso vakafa nekuda kwekusangana kwakananga kune pyrethroids.Mhedzisiro yacho inoratidza mukana wakakura wekubatanidza, asi kutsvagisa kwakawanda kunodiwa kudzokorora mhedzisiro uye kuona maitiro ebhayoloji, akadaro.
Pyrethroids ndeimwe yezvipembenene zvipembenene zvakanyanya kushandiswa nemugove wemusika, zvichiverengera kuwanda kwezvipembenene zvekutengesa zvemumba.Iwo anowanikwa mumhando dzakawanda dzekutengeserana dzezvipembenene uye anoshandiswa zvakanyanya kudzora zvipembenene mune zvekurima, zveveruzhinji uye zvekugara.Metabolites ye pyrethroids, yakadai se 3-phenoxybenzoic acid, inogona kuwanikwa muweti yevanhu vari pachena kune pyrethroids.
Bao nechikwata chake chetsvakurudzo vakaongorora dhata pamusoro pe3-phenoxybenzoic acid mazinga mumasampuli eweti kubva kuvanhu vakuru 2,116 vane makore 20 zvichikwira vakapinda muNational Health and Nutrition Examination Survey pakati pa1999 na2002. data data yakanga yafa ne2015 uye nei.
Vakaona kuti pamusoro peavhareji yekutevera nguva yemakore gumi nemana, ne 2015, vanhu vane mazinga akakwirira e-3-phenoxybenzoic acid mune weti samples vaiva 56 muzana mukana wekufa kubva kune chero chikonzero kupfuura vanhu vane mazinga akaderera ekuratidzwa.Chirwere chemwoyo, icho chiri chikonzero chikuru chekufa, chinogona kuitika zvakapetwa katatu.
Kunyange hazvo ongororo yaBao isina kuona kuti zvidzidzo zvakaiswa sei kune pyrethroids, akati zvidzidzo zvekare zvakaratidza kuti kuratidzwa kwakawanda kwepyrethroid kunoitika kuburikidza nekudya, sezvo vanhu vanodya michero nemiriwo yakapfapfaidzwa nepyrethroids vanodya kemikari.Kushandiswa kwemapyrethroids ekudzora zvipembenene mumagadheni nedzimba zvakare kwakakosha sosi yekutapukira.Pyrethroids inowanikwawo muguruva remumba umo mishonga iyi yezvipembenene inoshandiswa.
Bao akacherekedza kuti chikamu chemusika chemishonga yepyrethroid chakawedzera kubva panguva yekudzidza ya1999 kusvika 2002, zvichiita kuti kufa kwemoyo kune chekuita nekufumurwa kwavo kwakawedzerawo.Nekudaro, kumwe kutsvagisa kunodiwa kuti uongorore kana iyi hypothesis ndeyechokwadi, Bao akadaro.
Pepanhau, "Kubatanidzwa kwekusangana nemishonga yepyrethroid uye njodzi yezvose-zvinokonzera uye chikonzero-chaicho kufa pakati pevakuru veUS," rakanyorwa pamwe naBuyun Liu naHans-Joachim Lemler weYunivhesiti yeIllinois Chikoro chePublic Health., pamwe chete naDerek Simonson, mudzidzi akapedza kudzidza paYunivhesiti yeI Illinois mune chetoxicology yevanhu.Yakabudiswa muna Zvita 30, 2019 chinyorwa cheJAMA Internal Medicine.
