Environmental monitoring i.e. the measurement of chemical exposures and effects in the receiving environment is a valuable tool for environmental assessment, environmental impact assessment (EIA) and environmental performance assessment. While environmental assessment predicts the environmental impact of an effluent, chemical release or product use, the only way of validating that prediction is to study the actual receiving environment. The environment itself is the final arbiter. Monitoring the receiving environment takes into account the interaction of chemical mixtures effluents, environmental amelioration and their long-term effects on exposed organisms.
Environmental laboratory plays a very important role in assessing the status of environment comprising both a-biotic (soil, water and air) and biotic (flora, fauna and human being) components. An environmental laboratory is a facility for processing samples taken from the environmental regime (air water, soil, and biota)both from the environment as well as from sources disposing into the environment (industries, domestic and agriculture sources, automobiles etc.). Laboratory services includes are mentioned below:
