Ungcoliseko lomoya wangaphandle kunye nezinto ezincinci (PM) zihlelwa njengezinto ezibangela umhlaza kubantu kwiQela loku-1. Unxulumano olungcolisayo nomhlaza we-haematologic luyabonisa, kodwa ezi ntlobo zomhlaza azifani ngokwendalo kwaye uvavanyo oluncinci alukho.
Iindlela
I-American Cancer Society Cancer Prevention Study-II Nutrition Cohort yasetyenziswa ukuhlola unxulumano phakathi kongcoliseko lomoya lwangaphandle nomhlaza we-hematologic wabantu abadala. Uqikelelo lonyaka lwenqanaba leqela le-Census block lwezinto ezincinci (PM2.5, PM10, PM10-2.5), i-nitrogen dioxide (NO2), i-ozone (O3), i-sulfur dioxide (SO2), kunye ne-carbon monoxide (CO2) zabelwe iidilesi zokuhlala. Umlinganiselo weengozi (HR) kunye ne-95% yezithuba zokuzithemba (CI) phakathi kongcoliseko olutshintshatshintsha ixesha kunye neentlobo ze-hematologic ziqikelelwe.
Iziphumo
Phakathi kwabathathi-nxaxheba abayi-108,002, abantu abayi-2659 abanesifo somhlaza segazi esibangelwa yimeko ethile bachongwa ukususela ngo-1992–2017. Amanqanaba aphezulu e-PM10-2.5 adibene ne-mantle cell lymphoma (HR nge-4.1 μg/m3 = 1.43, 95% CI 1.08–1.90). I-NO2 idibene ne-Hodgkin lymphoma (HR nge-7.2 ppb = 1.39; 95% CI 1.01–1.92) kunye ne-marginal zone lymphoma (HR nge-7.2 ppb = 1.30; 95% CI 1.01–1.67). I-CO idibene ne-marginal zone (HR nge-0.21 ppm = 1.30; 95% CI 1.04–1.62) kunye ne-T-cell (HR nge-0.21 ppm = 1.27; 95% CI 1.00–1.61) lymphomas.
Izigqibo
Indima yongcoliseko lomoya kumhlaza we-hematologic isenokuba yayingathathelwa ngqalelo ngaphambili ngenxa yokungafani kweentlobo ezahlukeneyo.
Sidinga umoya ococekileyo ukuze siphefumle, kwaye uninzi lwezicelo zifuna iimpawu zomoya ezifanelekileyo ukuze zisebenze ngokufanelekileyo, ngoko ke kubalulekile ukuba siqaphele indawo esikuyo. Kule meko, sinikezela ngeendidi ezahlukeneyo zeenzwa zokusingqongileyo ukuze sibone izinto ezifana ne-ozone, i-carbon dioxide kunye nee-volatible organic compounds (ii-VOC).
