Abstract
Nigeria as a developing country is witnessing population growth and rapid urbanization. Consequently, the demand for electric power supply and other infrastructures to support the growth is on the increase. In response, many thermal power plants (TPP) that run on liquid and gaseous fossil fuels are widely used in the country. However, the effects of the emissions from these power plants on human health and the environment have become matters of serious concern. High concentrations of various air pollutants have been reported across the country, and evidences of air pollution related morbidities abound. This paper presents the major types of Air pollutants and Greenhouse gases emitted by these units and their adverse impacts on the environment and health of the citizenry. Abatement techniques for some of the major emissions are also highlighted. The monitoring of the level of emissions and their control systems at these thermal power plants is strongly suggested so as to ensure their strict compliance to appropriate Ambient Air Quality Standards. There is urgent need to put in place legislations to enforce air quality standards in Nigeria as well as reduce the indiscriminate use of diesel and petrol generators through adequate public power supply. These will guarantee the health of the citizenry and the safety of the environment.
