Ibikoresho byo Gupima Ibidukikije Bigamije Ubuziranenge bw'Umucyo

Umwanda wo mu kirere n'udukoko two mu bwoko bwa PM bishyirwa mu cyiciro cya mbere cy'itsinda rya mbere ry'indwara za kanseri y'ibihaha. Impuzandengo y'umwanda iterwa na kanseri y'amaraso iragaragaza ibimenyetso, ariko izi kanseri ziratandukanye mu buryo bw'umwimerere kandi nta suzuma ry'ubwoko bwazo rihari.

Uburyo
Inyigo ya kabiri y’umuryango w’Abanyamerika urwanya kanseri yakoreshejwe mu gusuzuma isano iri hagati y’imyanda ihumanya ikirere yo hanze na kanseri y’amaraso y’abantu bakuru. Isuzuma ry’umwaka ry’itsinda ry’abantu ku rwego rw’ibarura ry’ibintu bito (PM2.5, PM10, PM10-2.5), azote dioxyde (NO2), ozone (O3), sulfur dioxyde (SO2), na monoxide de carbone (CO2) ryashyizwe hamwe n’aho batuye. Ibipimo by’ingaruka (HR) n’intera z’icyizere cya 95% (CI) hagati y’imyanda ihindagurika mu gihe n’ubwoko bw’amaraso byagereranyijwe.

Ibisubizo
Mu bantu 108.002 bitabiriye, kanseri 2659 z’amaraso zagaragaye kuva mu 1992–2017. Igipimo cyo hejuru cya PM10-2.5 cyagaragaye ku ndwara ya lymphoma ya mantle cell (HR kuri 4.1 μg/m3 = 1.43, 95% CI 1.08–1.90). NO2 yagaragaye ku ndwara ya lymphoma ya Hodgkin (HR kuri 7.2 ppb = 1.39; 95% CI 1.01–1.92) na lymphoma ya marginal zone (HR kuri 7.2 ppb = 1.30; 95% CI 1.01–1.67). CO yagaragaye ku ndwara ya marginal zone (HR kuri 0.21 ppm = 1.30; 95% CI 1.04–1.62) na T-cell (HR kuri 0.21 ppm = 1.27; 95% CI 1.00–1.61).

Umwanzuro
Uruhare rw'imyuka ihumanya ikirere ku ndwara za kanseri z'amaraso rushobora kuba rwaragabanutse mbere bitewe n'ubwoko butandukanye bw'indwara.

Dukeneye umwuka mwiza kugira ngo duhumeke, kandi inyinshi mu bikorwa bisaba imiterere ikwiye y'umwuka kugira ngo dukore neza, bityo ni ngombwa kumenya ibidukikije. Muri urwo rwego, dutanga uburyo butandukanye bwo kumenya ibintu nk'umwuka wa ozone, umwuka wa karubone n'ibintu bihumanya ikirere (VOCs).
