The prediction of appropriate stack height at the Makurdi industrial layout in Benue State of Nigeria is carried out using the point source Gaussian plume model. The model takes into account the ambient environmental conditions and emission source parameters to calculate and estimate the appropriate stack height for three prevailing atmospheric stability classes, A, D and F within the Makurdi Industrial layout. The research estimates an appropriate stack height of ~65.0m for the Makurdi industrial layout. The results set a baseline for environmental safety standards for industries operating at the industrial layout and can be adopted by the National Environmental Standard Enforcement and Regulatory Agency (NESERA), and other concerned authorities in environmental monitoring and pollution control.

This article describes a computer program that estimates air pollutant concentrations in the vicinity of an elevated point source. The program is intended to be used in screening applications, i.e. applications where it is necessary to make a rapid analysis of a number of scenarios in order to identify situations where there may be cause for concern. The program uses a steady state Gaussian plume model and is based, with a number of exceptions, on Turner’s workbook. It is capable of calculating concentrations in cases of straightforward advection-diffusion, i.e. with a very high mixing layer, as well as in cases of fumigation or multiple reflections. The atmospheric stability classification is done with a scheme which applies to Highveld conditions. Both plume rise and plume spread are calculated using formulas established by Briggs. The effect of topography on the plume trajectory is taken into account in a rudimentary manner.

Non Point Source Pollution

With the effectively control of the point source pollution, non-point source pollution has become the most serious pollution source in our country. In addition, the agricultural non-point source pollution control has become the most important part of the environmental protection. By referring to related journals, this article makes a comprehensive analysis on definition, characteristics, mechanism, harm and prevention countermeasures of agricultural non-point source pollution.
