Kusvibisa kune zvakawanda zvinokanganisa utano hwevanhu; kunyanya kunonyanya kunetseka igadziriro yekufema. Ongororo ichangoburwa yakabatanidza huwandu hwekusvibiswa kwepamusoro kune huwandu hwehuwandu hwekurohwa, chimwe chinhu chinotsvakwa nevatsvaguri chinosimbisa humbowo huri kukura hwekuti huwandu hwemhepo uye shanduko yemamiriro ekunze zvinokonzeresa chirwere chemoyo.

Yakapiwa paInternational Stroke Conference, ongororo iyi yakashandisa mashoko kubva kuUnited States neChina nokuti “ndidzo nyika mbiri dzinobudisa magreenhouse gasi uye dzinokonzera chikamu chimwe muzvitatu chokupisa kwepasi kusvika pari zvino,” akadaro Dr. Longjian Liu, tungamira munyori wekudzidza uye akabatana purofesa we epidemiology uye biostatistics paDrexel yunivhesiti, mune chirevo. Tsvagiridzo iyi ndiyo yekutanga yerudzi rwayo, ichiongorora kudyidzana pakati pekurohwa kwekurohwa, mhando yemhepo, uye zvinogona kuitika zvetembiricha pamubatanidzwa.

Chikwata chekutsvagisa chakatarisa data remhando yemhepo kubva pakati pa2010 na2013, kubva mudunhu 1, 118 mumatunhu makumi mana nemapfumbamwe muAmerica nemaguta zana nemakumi maviri mumatunhu makumi matatu nemaviri muChina. Zvimedu zviri mumhepo, zvinosanganisira huruva, madonhwe emvura, uye utsi, zvinodaidzwa kuti particulate matter (PM) uye kuyerwa nemamicrometer. Dambudziko guru rehutano kuvanhu rinokonzerwa nezvikamu zvisingasviki 2.5 micrometers mudhayamita (PM2.5), zvimedu zvinogadzirwa nekupisa kubva kumotokari, moto wemasango, magetsi, nezvimwewo.

Maererano nekudzidza, nhamba yose yezviitiko zvekurohwa yakasimuka 1.19 muzana yega yega 10 micrograms pa cubic mita yekuwedzera kwemhepo yePM2.5. Pamusoro pezvo, Liu akati, timu yakawana musiyano wakakura wedunhu mumazinga ePM2.5 ayo akabatana nehuwandu hwezviitiko zvesitiroko - semuenzaniso, dunhu rekumaodzanyemba kweAmerica raive neavhareji yepamusoro pagore Pm2.5, nepo West vaine yakaderera, iyo inopindirana nenyaya yekuti Maodzanyemba aive nepamusoro-soro kupararira kwesitiroko uye Madokero aive neakaderera. Tembiricha yakakonzerawo hunhu hwemhepo uye njodzi yesitiroko.

"Kusiyana kwemwaka mumhando yemhepo kunogona kukonzerwa nekushanduka kwemamiriro ekunze," Liu akadaro. “Muzhizha, kune mazuva mazhinji ekunaya uye kune mhepo, izvo zvinogona kubatsira kuparadzira kusvibiswa kwemhepo. Tembiricha yakakwira inokonzeresa kushushikana kwakanyanya kunogona kukonzera njodzi yekurohwa nekumwe kupisa uye hurwere hwemhepo nerufu.”

Liu akawedzera kuti varwere vesitiroko vari munjodzi yekupererwa nemvura nekuda kwekupisa kwakanyanya, uye kuti vakadzi nevakweguru vanoratidzika kunge vari panjodzi yekubatwa nesitiroko nekuda kwemhando yemhepo uye zvirwere zvine chekuita nekupisa.

Stroke ndechimwe chezvikonzero zvikuru zvekufa muUnited States, ichiuraya vanhu vangangosvika 129,000 gore rega rega. Huwandu hwevanhu pasi rose hwasvika pamamiriyoni makumi matatu nematatu, uye sitiroko ndiyo yechipiri pakufa kwechirwere chemoyo pasi rose. Liu akati kunyangwe vanhu vasingakwanise kudzora mhando yemhepo, zvakawanikwa zvinopa humbowo kune vanogadzira hutano hweveruzhinji kuchengetedza zvirinani vagari.
