Introduction

The Environmental Chemistry Teaching Laboratory (ECTL) provides teaching and research capacity in the areas of analytical and environmental chemistry. Scientists identify and measure concentrations of toxic chemicals in many different media including air, water, soil, hazardous waste streams, and biological or human tissues. These efforts require the application or adaptation of existing procedures as well as the development of new analytical methods when required. The cycling of chemical species, the effect of man-made inputs, and environmental analytical methodology are stressed. This laboratory is active in several research areas including emerging contaminants, advanced analytical techniques, and conventional and novel physical-chemical treatment processes for water and waste systems.
