| Abstract: | The much publicised problem with major asbestos pollution and related health issues in South Africa, has called for action
to be taken to negate the situation. The aim of this project was to establish a prioritisation index that would provide a
scientifically based sequence in which polluted asbestos mines in Southern Africa ought to be rehabilitated. It was reasoned
that a computerised database capable of calculating such a Rehabilitation Prioritisation Index (RPI) would be a fruitful departure
from the previously used subjective selection prone to human bias. The database was developed in Microsoft Access and both
quantitative and qualitative data were used for the calculation of the RPI value. The logical database structure consists
of a number of mines, each consisting of a number of dumps, for which a number of samples have been analysed to determine
asbestos fibre contents. For this system to be accurate as well as relevant, the data in the database should be revalidated
and updated on a regular basis. |
