The role of the Professional Engineer in the 21st century

In light of the current world economic and environmental crisis due in part to
unsustainable development and poor financial planning, 21st Century engineers are faced with unprecedented challenges of developing a sustainable world in balance with the forces of nature to combat global environmental, social and economic crises. The European Union, the United States of America and a number of other countries have identified that smart solutions and highly skilled professionals are needed to survive climate change and create long-term prosperity. In this paper the evolution of the changing career of the engineer will be presented. The policy background to the current system of engineering education at bachelor’s and graduate level in Ireland will be introduced and perceptions of engineering as a profession by society in general, and by
school leavers selecting third level courses will be discussed. The role of the engineer as a specialist, expert or generalist will also be studied in terms of the changing demands and needs of society. Finally the responsibility of universities, through broad-based multidisciplinary teaching and training, to prepare the next crop of engineers will be examined.

Geochemical analysis of sediments from a polluted waterway in the vicinity of a metallurgical plant, Minas Gerais, Brazil

Mining and metallurgical industries are the most responsible for heavy metal contamination. These contaminants are often associated to poor management strategies and the lack of suitable containment areas. This is the case of one of the largest metal alloy producers in the São Francisco river basin, in Minas Gerais state, Brazil. During operation, the tailings of this activity have been accumulated in the surrounding area, leading to heavy metal contamination (Mn, Cu, Zn, Ni, Pb, Cd, Cr and As), much above the critical levels, which accumulate in the sediments of the nearby waterways, in the soils of the drainage area, and in the water column. In this work we are going to discuss both the contamination level and its extent in the Consciência river, a small tributary of the São Francisco river, the longest river entirely Brazilian, by analyzing the geochemistry and mineralogy of the accumulated sediments. It will be also discuss the reclamation strategies of this site and the impact on the environment.
