ABSTRACT

The environmental consequences are defined as consequences of accidental release of hazardous substances to the natural environment. This release can lead to many hazards depending on the material stored. The consequences of these hazards to the environment are widespread and have significant importance to human communities living in the surroundings. The mathematical models are extremely useful tools to predict the impacts of chemical process accidents. The objective of this paper is to develop a software package for accident simulation and damage potential estimation. The software is coded in visual basic and is compatible with windows working environments. The software is called Simulation of chemical industrial accident. This application is a comprehensive software package which can be integrated with geographical information system to predict and display the consequence of chemical hazards. The software is a user-friendly and effective tool for evaluating the consequences of major chemical accidents, process decision making for land-use planning, namely locating suitable hazardous installations, hazardous waste disposal areas and emergency response plan

ABSTRACT

A study was conducted to determine the influence of parent material on the contents and distribution of boron and zinc in soils of Bauchi State, Nigeria. Fourty nine, 30, and 20 top 0-30cm soil samples developed from basement complex rock, Kerri-Kerri Formation and Chad Formation, respectively, were collected and analysed using standard laboratory procedures. Results obtained indicate that parent material influenced Zn but not B contents in the soils. Generally, both B and Zn varied widely [CV > 30%] between locations in the State, irrespective of the parent material. Organic carbon significantly [P < 0.01] and negatively correlated with Zn in soils from BCR [r = -0.410] and CF [r = -0.563] and positively with B in soils developed from KKF [r = 0.471] and CF [r = 0.345]. With means of 0.41 and 1.46 mgkg[-1] for B and Zn respectively, their contents are considered adequate for crop growth. Crops grown on soils in some localized areas identified with values below the critical limits for these micronutrients may, however, benefit from their application
