木炭生产过程中经常伴随着气体和颗粒物排放到大气中，职业接触工人可能会受到影响。这项横向比较研究是为了评估一氧化碳（CO）、二氧化碳（CO2）、二氧化硫（SO2）、二氧化氮（NO2）和颗粒物的水平木炭生产过程中产生的PM2.5及其与木炭工人中某些生物标志物的关系（受试者）和非木炭工人（对照）如Igbo-Ora中的碳氧血红蛋白（COHb）、呼气第一秒用力呼气量（FEV 1）、呼气峰流速（PEFR）和体重指数（BMI），奥约州和奥贡州的阿斯塔纳塔是尼日利亚西南部的两个主要木炭生产中心。有目的地选择了Igbo-Ora的四个社区和Amarata的六个社区，并使用适当的气体测量仪评估污染气体的水平，使用Thermo Scientific MIE pDR-1500评估PM2.5，使用Piko-1肺活量计测量FEV 1和PEFR，同时使用非侵入式脉冲CO血氧计（Rad 57）评估COHb。对数据进行统计分析，并将结果与推荐的指南进行比较。受试者和对照组的FEV 1、PEFR、COHb和BMI分别为2.35 ± 0.73和2.69 ± 0.56，253.72 ± 103.45和330.02 ± 94.61分别为13.28 ± 3.91和8.50 ± 3.68（p <0.01）; 21.97 ± 2.19和23.36 ± 3.74（p < 0.05）。木炭工FEV 1（p < 0.01）和PEFR（p < 0.01）的实际值与期望值之间有显著性差异。CO与COHb呈正相关，FEV 1和PEFR与PM2.5呈负相关。该研究表明，木炭工人暴露于高水平的CO和PM2.5，与对照组相比，导致FEV 1和PEFR的呼吸功能降低以及COHb水平升高。还建议对参与木炭生产的人员进行常规呼吸和碳氧血红蛋白评估。
Charcoal production is often accompanied with gaseous and particulate emission into the atmosphere and occupationally exposed workers could be affected. This cross sectional comparative study was carried out to assess the levels of carbon monoxide (CO), carbon dioxide (CO2), sulphur dioxide (SO2), nitrogen dioxide (NO2) and particulate matter (PM2.5) generated during the phases of charcoal production and their relationship with certain biomarkers among charcoal workers (subjects) and non-charcoal workers (controls) such as carboxyhaemoglobin (COHb), forced expiratory volume in the first second of expiration (FEV1), peak expiratory flow rate (PEFR) and body mass index (BMI) in Igbo-Ora, Oyo State and Alabata, Ogun State, which are two of the major hubs of charcoal production in South Western Nigeria. Four communities in Igbo-Ora and six communities in Alabata were purposively selected and levels of pollutant gases were assessed using appropriate gas meters, PM2.5 was assessed with Thermo Scientific MIE pDR-1500, FEV1 and PEFR were measured with Piko-1 spirometer while COHb was assessed using non-invasive pulse CO-oximeter (Rad 57). Data were statistically analyzed and results were compared with recommended guidelines. The mean FEV1, PEFR, COHb and BMI for subjects and controls were 2.35 ± 0.73 and 2.69 ± 0.56, 253.72 ± 103.45 and 330.02 ± 94.61 (p < 0.01), 13.28 ± 3.91 and 8.50 ± 3.68 (p < 0.01) and 21.97 ± 2.19 and 23.36 ± 3.74 (p < 0.05) respectively. There was a statistically significant difference between actual and expected values of FEV1 (p < 0.01) and PEFR (p < 0.01) among charcoal workers. There existed a positive correlation between CO and COHb while FEV1 and PEFR correlated negatively with PM2.5. The study showed that charcoal workers are exposed to high levels of CO and PM2.5, contributing to lowered respiratory functions for FEV1 and PEFR and high levels of COHb compared to the control group. Routine respiratory and carboxyheamoglobin assessment of persons involved in charcoal production is also recommended.
