Evaluation of Pollutants Along the National Road N2 in Togo using the AERMOD Dispersion Model

Abstract

BACKGROUND: Air pollution has become a major problem around the world and is increasingly an issue in Togo due to increased vehicular traffic. Gaseous pollutants are released by engines and are very harmful to human health and the environment. The fuels used on the major road in Togo, the N2, are adulterated with unknown contents and are of poor quality. Many of the vehicles come from neighboring countries, such as Benin, Ghana and Nigeria. OBJECTIVES: ), and particular matter (PM) on the international road, the National Road N2, in Lomé, compared to the World Health Organization's (WHO) standard limit. METHODS: and PM contained in the fuel. RESULTS: was twice the permissible limits set by the WHO. CONCLUSIONS: was twice the permissible limit. The fuels used on this road were very rich in sulfur. The sulfur level in fuels must be monitored by stakeholders in Togo. COMPETING INTERESTS: The authors declare no competing financial interests.
