The European Southern Observatory is planning to construct its Very Large Telescope on Cerro Paranal, a site with superb astronomical observing conditions located in the Atacama Desert of Northern Chile some 100 km south of the town of Antofagasta and 16 km from the Pacific Ocean. This region of Chile is know for its rich mineral resources. One of these, Nitrates, are mined by surface, strip mining causing extensive area air pollution. To estimate the effects of a Nitrate mine which may be started 25 km SSE from Cerro Paranal a model for this pollution, based on estimates of aerosols resulting from similar mines north of Antofagasta, was developed. These estimates are based on measurements of the solar aureole brightness. The expected deteriorating effects on atmospheric extinction, sky thermal emissivity and night-time sky brightness appear acceptable.
