Viwango fulani vya uchafuzi wa hewa vilivyochukuliwa kuwa salama hapo awali vinaweza kusababisha idadi ya magonjwa na kuzuia ukuaji wa ubongo kwa watoto, watafiti wanasema.<\/p>\n

Utafiti mpya wa longitudinal, uliochapishwa kwenye jarida Mazingira ya Kimataifa<\/a>, alibainisha kuwa hata viwango vya chini vya uchafuzi wa mazingira vinaweza kuingilia kati miunganisho kati ya maeneo ya ubongo, ambayo inaweza kusababisha tishio kubwa kwa maendeleo ya utambuzi.<\/p>\n

Waandishi wa utafiti, kutoka Chuo Kikuu cha Kusini mwa California (USC), walitumia data ya uchunguzi wa ubongo kutoka kwa washiriki zaidi ya 9,000 katika utafiti wa Maendeleo ya Ubongo wa Vijana (ABCD), utafiti mkubwa zaidi wa kitaifa kwa afya ya ubongo wa vijana nchini Marekani.<\/p>\n

Walipata katika baadhi ya maeneo ya ubongo, kulikuwa na ongezeko la idadi ya miunganisho ikilinganishwa na kile kinachochukuliwa kuwa kawaida, wakati maeneo mengine ya ubongo yalionyesha miunganisho machache.<\/p>\n

Jinsi uchafuzi wa mazingira huathiri ukuaji wa ubongo?<\/strong><\/p>\n

Uhusiano kati ya maeneo mbalimbali ya ubongo ni muhimu kwa maendeleo yake na utendaji wa kila siku. Mawasiliano huwa na sehemu muhimu katika vipengele mbalimbali, kuanzia jinsi ubongo unavyokusanya taarifa na jinsi tunavyofikiri na kuhisi.<\/p>\n

Miunganisho mingi kati ya hizi hughushiwa mapema, kati ya umri wa miaka tisa na 12. Huchukua jukumu kubwa katika ukuaji wa akili wa kiakili na kihisia wa watoto.<\/p>\n

"Ubora wa hewa kote Amerika, ingawa 'salama' kwa viwango vya EPA [Shirika la Ulinzi wa Mazingira], unachangia mabadiliko katika mitandao ya ubongo wakati huu muhimu, ambayo inaweza kuonyesha alama ya mapema ya hatari ya kuongezeka kwa shida za utambuzi na kihemko baadaye maishani, "soma mwandishi mwandamizi Megan Herting, profesa msaidizi wa Sayansi ya Idadi ya Watu na Afya ya Umma huko USC, aliiambia. Earth.com.<\/a><\/p>\n

Herting na timu yake walichunguza uhusiano kati ya uchafuzi wa hewa na maendeleo ya ubongo kwa kufuatilia uchunguzi wa MRI unaofanya kazi kutoka kwa washiriki 9,497 wenye umri wa miaka 9-10. Sehemu ndogo ya kikundi hiki ilichaguliwa kwa uchunguzi wa ziada miaka miwili baadaye ili kuona mabadiliko katika muunganisho wa ubongo baada ya muda.<\/p>\n

Watafiti walilenga mitandao mahususi ya ubongo, ikiwa ni pamoja na mitandao ya salience, frontoparietal na default-mode, pamoja na amygdala na hippocampus.<\/p>\n

Wanasayansi walitumia data ya EPA, ikiwa ni pamoja na viwango vya chembe chembe ndogo (PM2.5), dioksidi ya nitrojeni (NO2) na ozoni ya kiwango cha chini (O3), kuweka ramani ya uchafuzi wa hewa katika makazi ya kila mshiriki na kuona jinsi yanahusiana na mabadiliko katika muunganisho wa ubongo. baada ya muda.<\/p>\n

Utafiti ulifunua kuwa mfiduo wa juu wa PM2.5 ulisababisha kuongezeka kwa muunganisho kati ya maeneo ya ubongo, wakati kuongezeka kwa mfiduo kwa NO2 ilipungua muunganisho. Mfiduo wa O3 ulihusishwa na miunganisho zaidi ndani ya gamba lakini miunganisho michache na maeneo mengine muhimu ya ubongo.<\/p>\n

"Kwa wastani, viwango vya uchafuzi wa hewa viko chini sana nchini Marekani, lakini bado tunaona madhara makubwa kwenye ubongo. Hilo ni jambo ambalo watunga sera wanapaswa kuzingatia wakati wanafikiria kuhusu kuimarisha viwango vya sasa,\u201d mwandishi mkuu wa utafiti Devyn Cotter alisema.<\/p>\n

Utafiti huo unasisitiza hitaji la wadhibiti kuzingatia afya ya ubongo pamoja na afya ya kupumua na moyo na mishipa huku wakiweka viwango vya ubora wa hewa.<\/p>\n
