Environmental protection against pollution and associated risk management and policies require multidisciplinary team work and the integrated action of professionals with complementary expertise capable of understanding each other and promoting synergies; say, chemists, geologists, ecologists, cellular and molecular biologists, toxicologists, and environmental engineers and managers. Likewise, responses over a time-scale of minutes, together with consequences at a time scale of decades or centuries need to be considered; and global processes and local scenarios altogether. This approach may be achieved by different specialists, but the latest trend is to incorporate people able to integrate all these diverse concepts, instruments and time-scales. Scientists and technologists with such a wide-ranging profile are becoming leaders in environmental contamination and toxicology research.
