This research presents a novel approach to assessing the health implications of black soot using a MiniVol air sampler. The MiniVol air sampler was used to collect PM from the ambient air at six monitoring sites in Port Harcourt, Nigeria. Sampling was conducted every day for seven days, for a period of 24 hours. PM2.5Â concentrations at Uniport Junction, GRA Junction, Slaughter Roundabout, Abuloma Jetty, Rumuomasi Roundabout, and New Road Borokiri were 38.6 g/m3Â , 28.3 g/m3Â , 93.7 g/m3Â , 72.9 g/m3Â , 30.6 g/m3Â , and 31.3 g/m3Â , respectively. PM10Â concentrations ranged from 71.2 g/m3Â to 60.6 g/m3Â , with 103.3 g/m3Â , 85.5 g/m3Â , 40.1 g/m3Â , and 35.2 g/m3Â being the highest. The level of PM2.5Â and PM10Â pollution in the ambient air was high across the six sampling sites, with mean PM2.5Â and PM10Â concentrations exceeding the WHO (2011) guideline. The flame atomic absorption spectrometry (FAAS) technique was used. The presence of heavy metals, such as mean metal concentrations of lead, cadmium, chromium, mercury, and nickel, ranged from 0.009 g/m3Â -0.532 g/m3Â , 0.002 g/m3Â - 0.544 g/m3Â , 0.002 g/m3Â -0.338 g/m3Â , 0.001 g/m3Â , and 0.001 g/m3Â -0.432 g/m3Â , across the six sampling sites. The GC-MS was used to determine the presence of PAHs in particulate matter. Correlation results revealed a strong positive correlation between PM2.5Â and PM10. The findings also revealed a positive relationship between the metals as well as between the metals and PAHs, resulting in asthma, lung cancer, breathing difficulties, and miscarriages among pregnant women, which have affected the health implications of the people living in the environment.
