Concentrations of polychlorinated biphenyl in indoor environment of public bars and its health implications.

This study determined the indoor air levels of polychlorinated biphenyls (PCBs) in some selected public bars in Southern part of Nigeria. The result obtained was used to carry out health risk assessment of exposure to PCBs in these indoor environment.s.

Indoor levels of polycyclic aromatic hydrocarbons (PAHs) from environment tobacco smoke of public bars.

In this work level of Polycyclic Aromatic Hydrocarbon (PAHs) from indoor Environment Tobacco Smoke (ETS) of pubic bars in Nigeria was investigated. Indoor air samples were obtained from different public bars using Polyurethane foam (PUF) passive samplers. Analysis of PAHs was carried out using GC-MS operated in selected ion monitoring mode.
