Choyambitsa chosayembekezereka cha khansa ya m'mawere

Kuyambira mu Okutobala chaka chilichonse, ntchito zachipatala padziko lonse lapansi zimayang'ana kwambiri kuphunzitsa anthu za khansa ya m'mawere.

Pankhani imeneyi, kafukufuku waposachedwapa wochitidwa pa akazi masauzande ambiri ku France anasonyeza kuti kupeŵa zinthu zingapo zowononga mpweya kungapangitse ngozi ya kudwala kansa ya m’mawere.

Kafukufukuyu, yemwe adatchedwa "Xenair" pakati pa zomwe adatsimikiza, adatsimikizira kuti kukhudzana ndi nitrogen dioxide (yomwe imapezeka m'mainjini oyatsira magalimoto - makamaka mu injini za dizilo - komanso pakuwotcha malasha, mafuta, gasi, nkhuni ndi zinyalala) kumawonjezera ngozi ya khansa ya m'mawere..

Komanso, kafukufuku wam'mbuyomu adawonetsa kale zomwe zimayambitsa matenda a chibadwa kapena mahomoni omwe amachititsa khansa ya m'mawere, yomwe ndi khansa yamtundu wambiri mwa amayi, komanso zinthu zokhudzana ndi zaka kapena moyo (mowa, masewera olimbitsa thupi, etc.). Komabe, kafukufuku wambiri wasonyeza m’zaka zaposachedwapa zochita za zinthu zina zoipitsa zinthu.

nayitrogeni dioxide

Olemba a meta-analysis yomwe idasindikizidwa mu 2021 idawonetsa kuti kuwonekera kwa nitrogen dioxide ndi chimodzi mwazinthu zomwe zingawopseze, ndipo adati pafupifupi 1700 milandu ya khansa ya m'mawere chaka chilichonse ku France imatha kulumikizidwa nayo. Iwo adawona kuti zomwe zapezedwa zokhudzana ndi zoopsa zomwe zimagwirizanitsidwa ndi tinthu tating'onoting'ono sizotsimikizika.

Olemba a "Kisner Study" adaphunzira za ubale womwe ulipo pakati pa chiwopsezo cha khansa ya m'mawere ndi kuwonekera kwanthawi yayitali pamilingo yochepera 10 yowononga mpweya, yomwe ndi zoipitsa xenoestrogenic, monga dioxins, benzo [a]pyrene (BaP), polychlorinated biphenyls ndi cadmium - ndi zoipitsa zomwe kukhudzana ndi tsiku ndi tsiku, Izi ndi zabwino particles (PM2.5 ndi PM2), nayitrogeni dioxide (NO3), ndi ozoni (OXNUMX), malinga ndi mawu amene anapereka.

Kafukufukuyu adaphatikizanso milandu 5222 ya khansa ya m'mawere yomwe idapezeka pakati pa 1990 ndi 2011 kuchokera kugulu ladziko lonse lotsatiridwa kwa zaka 22, poyerekeza ndi chiwerengero chofananira chaumoyo.

Kuwonekera kwapakati komanso kochulukira kwa mkazi aliyense kunayesedwa pa choipitsa chilichonse, poganizira zambiri, kuphatikiza malo okhala.

Iwo anapeza kuti chiopsezo kukhala ndi khansa ya m`mawere kumawonjezera milandu kukhudzana nayitrogeni dioxide.

kuwononga chilengedwe

Kafukufuku wokhudzana ndi zotsatirazi akuyembekezeka kusindikizidwa mu nyuzipepala ya Environmental Pollution.

Chiwopsezo chowonjezereka chawonetsedwanso kuti chikugwirizana ndi benzo[a]pyrene ndi polychlorinated biphenyls 153, zomwe zimasokoneza endocrine.

Ndizofunikira kudziwa kuti kafukufukuyu adachitidwa ndi mamembala a British University of Leicester, Lyon-Perard Center ndi Ecole Centrale de Lyon kum'mwera chakum'mawa kwa France, Gustave Roussy Institute m'chigawo cha Parisian, National Institute for the Industrial Environment ndi Ma Risks (Ineris) okhala kumpoto kwa Paris, ndi Population Health Center ku Bordeaux (kum'mwera kwa Paris). kumadzulo kwa France). Zotsatira za kafukufukuyu zikugwirizana ndi zomwe zinapezeka mu kafukufuku wina waposachedwapa.
