Abstract:

This literature review of the effects of turbidity and suspended material in aquatic environments covers the following subjects definitions, units of measure, and methods of measurement origins and effects in aquatic environments. Turbidity, regardless of the multiplicity of definitions, units of measure, and methods of measurement, is an expression of the optical properties of water that cause light to be scattered and absorbed rather than transmitted in a straight line. Turbidity is not the same as siltation, although the terms have been used synonymously in the past. The various units of measure include the Jackson Turbidity UNIT JTU, Formazin Turbidity Unit FTU, and Nephelometric Turbidity Unit NTU. The methods of measuring percent transmission or the weight per volume concentration of suspended particulates are based on either gravimetric or optical techniques.
