Chlorine gas is widely known as obnoxious gas in the environment. It is well documented that little amount of chlorine gas in the atmosphere can cause pulmonary edema, pneumonitis, emphysema, bronchitis, and irritation of eyes, throat, and nose, just to mention a few. The thrust of this work is to investigate the breathing disease and health hazard emanating from the inhalation of chlorine concentration in particulate matter during job activities. This work was conducted among 120 employers from nine (9) industries. Information of the various ailments were gathered by using questionnaires and spirometry. The spirometry has an opening in which one blows in air to determine the lung volume. The commonest symptoms in the work were cough 47.5%, phlegm expectoration 50.0%, wheeze 5.8%, chest tightness 10.0%, chest pain 5.7%, breathlessness 8.3%, and cough with phlegm 8.3%. The concentration of chlorine in the total suspended particle ranged from 0.005 to 0.189 ppm, while the mean concentration of chlorine in the inhalable particle ranged from 0.112 to 0.270 ppm, and the concentration of chlorine gas in respirable particle ranged from 0.070 to 0.266 ppm. Further study should be conducted to enable establishment of reference level for the state.

尼日利亚贝宁市大气颗粒物中氯浓度的毒理学评估

氯气是众所周知的环境中的有害气体。众所周知,大气中少量的氯气会导致肺水肿、肺炎、肺气肿、支气管炎以及眼睛、喉咙和鼻子的刺激,仅举几例。这项工作的重点是调查在工作活动中吸入颗粒物中的氯浓度所引起的呼吸疾病和健康危害。这项工作是在来自九 (9) 个行业的 120 名雇主中进行的。通过使用问卷和肺活量测定法收集各种疾病的信息。肺活量计有一个开口,可以在其中吹入空气以确定肺容积。工作中最常见的症状是咳嗽47.5%,咳痰50.0%,喘息5.8%,胸闷10.0%,胸痛5.7%,呼吸困难8.3%,咳痰8.3%。总悬浮颗粒物的氯浓度范围为0.005至0.189 ppm,而可吸入颗粒中氯的平均浓度范围为0.112至0.270 ppm,可吸入颗粒中氯气的浓度范围为0.070至0.266 ppm。应进行进一步研究,以便为国家建立参考水平。
