Her areas of competence are: ore treatment, environmental geochemistry, controlled waste disposal, licencing and control of mining activities and chemical industry.

"Without a doubt, this book is a prime example for environmental assessment of Arsenic contamination where natural processes and anthropogenic activities interfere with each other. The concepts and methods presented here are not restricted to the Brazilian environment but can be transferred also to other regions of the globe as well as to other pollutants. The book provides environmental scientists, technicians and planners with an excellent example on how to design and conduct interdisciplinary studies on environmental pollution and how to draw sensible conclusions from their findings."—S.
