Abstract
The suspended fine particulate matter concentrations in Makurdi and Otukpo Metropolis were measured using Haz-Dust Sampler (AMS 95015). The measurements were carried out at major observed emission sources such as residential and traffic related sources. On the average, traffic- related sources recorded the highest concentration of suspended fine particulate matter in both metropolis with the highest concentration in Otukpo metropolis (594 : g/m ). Generally the measured values from all the sources are above World Health Organization (WHO) standards and National Air Quality Standard (150-230 : g/m 3 for 24 hrs). Results show that Otukpo metropolis has the highest fine particulate concentrations from residential and traffic related sources. In order to keep the suspended fine particulate concentrations from rising above prescribed standards, appropriate control measures are recommended.
