Ukungcoliswa komoya wangaphandle kanye nezinto ezincane (PM) kuhlukaniswa njengezinto ezibangela umdlavuza kubantu zeQembu 1 lomdlavuza wamaphaphu. Ukuxhumana kokungcola nomdlavuza we-hematologic kuyasikisela, kodwa lezi zomdlavuza azifani ngokwe-aetiologically futhi ukuhlolwa kohlobo oluthile akutholakali.
Izindlela
I-American Cancer Society Cancer Prevention Study-II Nutrition Cohort yasetshenziswa ukuhlola ukuhlobana kokungcola komoya kwangaphandle nomdlavuza we-hematologic wabantu abadala. Izibikezelo zonyaka zezinga leqembu le-Census block zezinto ezincane (PM2.5, PM10, PM10-2.5), i-nitrogen dioxide (NO2), i-ozone (O3), i-sulfur dioxide (SO2), kanye ne-carbon monoxide (CO) zanikezwa ngamakheli okuhlala. Izilinganiso zengozi (HR) kanye nezikhawu zokuzethemba ezingama-95% (CI) phakathi kokungcola okuguquguqukayo kwesikhathi kanye nezinhlobo ze-hematologic zalinganiselwa.
Imiphumela
Phakathi kwabahlanganyeli abangu-108,002, kwatholakala umdlavuza we-hematologic ongu-2659 kusukela ngo-1992–2017. Amazinga aphezulu e-PM10-2.5 ahlotshaniswa ne-mantle cell lymphoma (HR nge-4.1 μg/m3 = 1.43, 95% CI 1.08–1.90). I-NO2 ihlotshaniswa ne-Hodgkin lymphoma (HR nge-7.2 ppb = 1.39; 95% CI 1.01–1.92) kanye ne-marginal zone lymphoma (HR nge-7.2 ppb = 1.30; 95% CI 1.01–1.67). I-CO ihlotshaniswa ne-marginal zone (HR nge-0.21 ppm = 1.30; 95% CI 1.04–1.62) kanye ne-T-cell (HR nge-0.21 ppm = 1.27; 95% CI 1.00–1.61) lymphomas.
Iziphetho
Indima yokungcola komoya kumdlavuza we-hematologic kungenzeka ukuthi yayingabhekwanga kahle ngaphambilini ngenxa yokungafani kwezinhlobo ezithile.
Sidinga umoya ohlanzekile ukuze siphefumule, futhi izinhlelo eziningi zidinga izici zomoya ezifanele ukuze zisebenze kahle, ngakho-ke kubalulekile ukuqaphela indawo esizungezile. Kulokhu, sinikeza uhla lwezinzwa zemvelo ukuthola izinto ezifana ne-ozone, i-carbon dioxide kanye nama-volatile organic compounds (ama-VOC).
