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.
Turbidity is caused by particles suspended. or dissolved in water that scatter light. making the water appear cloudy or murky. Particulate matter can include sediment -. especially clay and silt, fine organic and. inorganic matter, soluble colored organic. compounds, algae, and other microscopic. organisms.
