These small solid particles cause the liquid to appear turbid. Turbidity (or haze) is also applied to transparent solids such as glass or plastic. In plastic production haze is defined as the percentage of light that is deflected more than 2.5Â° from the incoming light direction.
Analyze effects of human action on an ecosystem BACKGROUND: Turbidity measures the cloudiness of water: the higher the turbidity, the cloudier the water. The numerical measurement is usually given in Jackson Turbidity Units (JTUs) or Nephelometric Turbidity Units (NTU); both are equal. Turbidity is caused by suspended inorganic matter
