Scientists need to improve understanding of the significance of analytical results relative to the environment. Scientific methodology has progressed yielding an impressive ability to measure minuscule quantities of contaminants, but the ability to understand the significance of those levels in the environment has not kept pace. Scientists must also improve their ability to accurately measure materials in complex matrices. The third area requiring attention in this decade is sampling protocols. Too much contamination and improper sampling strategies are negating the accuracy of high-precision analytical efforts. These are the challenges of the 1990s.
