Abstract
In this paper we evaluate the environmental impact of dust emission from a magnesite calcination factory during the last 40 years over an area of about 600 ha in northern Spain. Our study aimed to determine the contamination levels through the spatial modifications induced on the soil pH by deposition of the dust, mostly composed of magnesium oxides. A soil survey of the area has been conducted by collecting soil samples at three different depths (0–2, 2–32 and 32–52 cm) following a square grid pattern. Our survey has evidenced an important and general pH increase of the soils. Thus, from original values of around 7, pH reaches alkaline values of above 9·5. IDRISI GIS techniques have been used to analyse and represent the spatial distribution of the pH values. Variations in the expected concentric circular pattern of soil pH distribution appear to be related to climatic factors, such as precipitation, wind direction and intensity. Also topography affects pH distribution through its ‘screen’ effect. The contamination levels in the area have a strong environmental impact responsible for the abandonment of some agricultural lands. Copyright © 2000 John Wiley & Sons, Ltd.
