Iwo ese ane mishonga yezvipembenene inonzi pyrethrins yaishandiswa muPersia yekare.Nhasi, tinozvishandisa mumashampoos ezviyo.
Tikugashirei kuJSTOR Daily's detox series, kwatinofunga nzira yekudzikamisa kuratidzwa kune zvinhu zvinoonekwa zvisina kuchengetedzeka nemasainzi.Kusvika pari zvino, takavhara zvinodzoreredza moto mumukaka, mapurasitiki ari mumvura, mapurasitiki nemakemikari mudhijitari detoxification.Nhasi, isu tinoteedzera kwakabva inda shampoo kuPersia yekare.
Mumakore mashoma apfuura, zvikoro munyika yose zvanga zvichirwisana nekupinda inda dzemumusoro.Muna 2017, muHarrisburg, Pennsylvania, vana vanopfuura zana vakawanikwa vaine inda, izvo zvakanzi nedunhu rechikoro "zvisina kumboitika."Uye muna 2019, chikoro chiri muSheepshead Bay chikamu cheBrooklyn School chakashuma denda.Kunyange zvazvo Centers for Disease Control and Prevention ichiwanzotenda kuti inda hadzina kukuvadza utano, dzinogona kuva dambudziko guru.Kuti ubvise inda uye mhute (mazai avo madiki), unofanirwa kugeza bvudzi rako ne shampoo ine mushonga unouraya zvipembenene.
Mishonga inouraya zvipembenene mumashampoos akawanda epa-the-counter ine komboni inonzi pyrethrum kana pyrethrin.Mushonga wacho unowanikwa mumaruva akadai setansy, pyrethrum uye chrysanthemum (inowanzonzi chrysanthemum kana chrysanthemum).Izvi zvinomera zvinogara zvine esters matanhatu akasiyana kana pyrethrins-organic makomisheni ane chepfu kune zvipembenene.
Zvakaonekwa kuti maruva aya aive nemishonga inouraya zvipembenene mazana emakore apfuura.Mukutanga kwema1800, Persian pyrethrum chrysanthemum yakashandiswa kubvisa inda.Maruva aya akatanga kurimwa zvokutengeserana muArmenia muna 1828, uye akarimwa muDalmatia (yava kunzi Croatia) anenge makore gumi gare gare.Maruva akagadzirwa kusvikira Hondo Yenyika Yekutanga.Chirimwa ichi chinoita zvakanaka munzvimbo dzinodziya.Muma1980, kugadzirwa kwepyrethrum kwaifungidzirwa kuva anenge matani 15 000 emaruva akaomeswa pagore, ayo anopfuura hafu yawo aibva kuKenya, uye mamwe acho akabva kuTanzania, Rwanda neEcuador.Vanhu vanenge 200 000 pasi rose vanotora chikamu mukugadzirwa kwayo.Maruva anotangwa nemaoko, oomeswa muzuva kana nemichina, ozokuyiwa kuita upfu.Ruva rega rega rinenge 3 kusvika 4 mg yepyrethrin -1 kusvika 2% nekurema, uye inoburitsa anenge 150 kusvika 200 matani emishonga yezvipembenene pagore.United States yakatanga kuunza hupfu muna 1860, asi kuedza kwekugadzirwa kwekutengeserana kwepamba hakuna kubudirira.
Mumazuva ekutanga, pyrethrum yakashandiswa sehupfu.Zvakadaro, kutanga kubva kutanga kwezana ramakore rechi 19, kuisanganisa neparafini, hexane kana zvinonyungudutsa zvakafanana kugadzira mvura yekupfapfaidza inoshanda kupfuura hupfu.Gare gare, analogis akasiyana-siyana ekugadzira akagadzirwa.Aya anonzi mapyrethroids (pyrethroids), ari makemikari ane chimiro chakafanana nepyrethroids asi ane chepfu kutumbuyu.Mumakore ekuma1980, mapyrethroids mana akashandiswa kuchengetedza zvirimwa-permethrin, cypermethrin, decamethrin uye fenvalerate.Mishonga mitsva iyi yakasimba uye inogara kwenguva refu, saka inogona kuramba iri mumhoteredzo, zvirimwa, uye kunyange mazai kana mukaka.Zvinopfuura chiuru zvesynthetic pyrethroids zvakagadzirwa, asi parizvino kune isingasviki gumi nembiri yekugadzira pyrethroids iri kushandiswa muUnited States.Pyrethroids uye pyrethroids inowanzoshandiswa pamwe chete nemamwe makemikari kudzivirira kuora kwavo uye kuwedzera kuuraya.
Kusvika nguva pfupi yadarika, pyrethroids yaionekwa seyakachengetedzeka kuvanhu.Kunyanya, zvinokurudzirwa kushandisa zvitatu zvepyrethroid deltamethrin, alpha-cypermethrin uye permethrin kudzora zvipembenene kumba.
Asi zvidzidzo zvenguva pfupi yapfuura zvakaona kuti pyrethroids haina njodzi.Kunyangwe iwo ari 2250 nguva yakawanda kune chepfu kune zvipembenene kupfuura vertebrates, anogona kuve nemhedzisiro inokuvadza pavanhu.Apo masayendisiti paYunivhesiti yeIowa akaongorora hutano hwehutano hwevanhu vakuru ve2,000 kuti vanzwisise kuti muviri unoputsa sei pyrethroids, vakawana kuti makemikari aya anowedzera katatu njodzi yechirwere chemwoyo.Ongororo yapfuura yakawanawo kuti kuratidzwa kwenguva refu kune pyrethroids (semuenzaniso muvanhu vanoaisa) kunogona kukonzera matambudziko ehutano akadai sedzungu uye kuneta.
Pamusoro pevanhu vanoshanda zvakananga nepyrethroids, vanhu vanosanganawo navo kunyanya kuburikidza nechikafu, nekudya michero nemiriwo zvakapfapfaidzwa, kana kana dzimba dzavo, patsangadzi nemapindu zvakapfapfaidzwa.Zvisinei, mishonga yemazuva ano yepyrethroid ndiyo yechipiri inonyanya kushandiswa pasi rose.Izvi zvinoreva here kuti vanhu vanofanirwa kunetseka nekugeza bvudzi ravo nepyrethrum-ine shampoo?Kugeza kushoma hakugone kukuvadza vanhu, asi zvakakosha kutarisa zvinongedzo pamabhodhoro emishonga yezvipembenene anoshandiswa kupfapfaidza dzimba, magadheni nenzvimbo dzine umhutu.
