The English/Spanish & Spanish/English Dictionary of Environmental Science and Engineering is aimed at the professional practitioner in the areas of business, consultancy, government, regulation or academia. It is particularly useful for environmental scientists, ecologists, geologists, hydrologists, water and wastewater engineers, landfill and contaminated land specialists and administrators. The diverse specialisms of the two authors and their knowledge of environmental assessment, hydrogeology and environmental engineering ensures that the book has thorough coverage. With nearly 30,000 entries, the book combines a traditional dictionary approach with a modern and up-to-date style of presentation. The authors have used their wealth of technical knowledge and their understanding of Spanish to produce a book of true value and timeliness. In addition, the external advisors, Manuel Regueiro y Gonzalez-Barros from Spain and Alberto Bustani Adem from Mexico bring their distinct cultural backgrounds to bear to ensure that the dictionary reflects modern usage and terminology in both Spain and Latin America.
