<prompt> Fingqa isihloko: Ososayensi bathi intuthu evela ekudleni okushisiwe ekhishini ingalimaza ubuchopho bezingane ezingakazalwa. Ngokufanayo, ukungcola okubangelwa imililo yamalahle nemisi yezimoto kuphazamisa izingxenye zobuchopho ezikhulayo ezisekela ukucubungula ukwaziswa nokuziphatha. Ukuhlolwa kwezingane zasemadolobheni kusukela ngaphambi kokuzalwa kuze kube yilapho zineminyaka eyisikhombisa kuya kweyisishiyagalolunye ubudala kwembula ukuthi lezo ezichayeke ezingeni eliphezulu lokungcola komoya zazinengxenye encane yemithambo-luvo emhlophe ebuchosheni bazo obungakwesobunxele, okwenza ubuhlakani bube buthakathaka futhi kubangele i-ADHD nobudlova. Skrolela phansi ukuze ubone ividiyo. Ochwepheshe baxwayisa ngokuthi intuthu evela ekudleni okushisiwe ekhishini ingalimaza ubuchopho bezingane ezingakazalwa. Njengoba zikhula zabangela izinkinga ekugxileni, ekucabangeni, ekwahluleleni, nasekuxazululeni izinkinga. Lolu cwaningo lwase - U.S. lwabheka i - PAH enobuthi bezinzwa - ama - polycyclic aromatic hydrocarbon - nemiphumela yayo ebuchosheni bezingane zasemadolobheni. Zitholakala emiphungeni yezimoto, emlilweni wamalahle noma emafutheni ezikhungweni zokushisa, ezitshalweni zikagesi, emlilweni wasendle nasekushisweni kwezolimo, intuthu kagwayi nasezindaweni zokulahla imfucuza eyingozi. Ucwaningo lwangaphambilini luye lwabonisa ukuthi i-PAH ingakwazi ukuwela kalula i-placenta futhi ithinte ubuchopho bengane engakazalwa futhi ucwaningo olwenziwe ezilwaneni lubonise ukuthi ukuchayeka ngaphambi kokubeletha kuphazamisa ukuthuthukiswa kokuziphatha, ukufunda nokukhumbula. Lolu cwaningo olwenziwe i- Institute for the Developing Mind e- Children s Hospital Los Angeles kanye ne- Columbia University s Centre for Children s Environmental Health lwahlola imiphumela ekwakhekeni kobuchopho ngenxa yokuchayeka kuma- PAH phakathi nenkathi yokugcina yokukhulelwa. Lalihilela ukuthatha izithombe zobuchopho zezingane ezingu-40 eNew York, ziqashwe ngaphambi kokuzalwa kuze kube yilapho sezineminyaka eyisikhombisa kuya kweyisishiyagalolunye. Umusi wethrafikhi, ukungcola okuvela emlilweni wamalahle nomusi wokudla okushisiwe kuphazamisa izingxenye zobuchopho obusakhulayo ezisekela ukucubungula ulwazi nokuziphatha. Babeyingxenye yochungechunge olunezimbhangqwana ezingaphezu kuka - 600 zomama nezingane lapho abacwaningi baseColumbia babike khona ngaphambili ukuthi ukuchayeka ku-PAH esemoyeni ngesikhathi sokukhulelwa kwakuhlotshaniswa nokuphazamiseka okuningi kokukhula kwezinzwa. Lezi zihlanganisa ukubambezeleka kokukhula lapho eneminyaka emithathu, ukwehla kwe-IQ yokukhuluma lapho eneminyaka emihlanu, nezimpawu zokukhathazeka...  <response>: Intuthu evela ekudleni, ukungcola, imililo yamalahle kanye nomgwaqo kuphazamisa ukuthuthukiswa. Ucwaningo lwaseMelika lwasebenzisa ukuhlolwa kwezingane zasemadolobheni ukuze kuhlolwe ukukhula kwamangqamuzana obuchopho. Izingane zabonisa izimpawu zokucindezeleka lapho zineminyaka eyisikhombisa uma zivezwa intuthu.
