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 Effects on Fish and Aquatic Life. The significance of excessive turbidity in water on fish and other aquatic life begins by modifying the temperature structure of lakes. Bottom temperatures are generally lower in turbid lakes or ponds than in clear ones. In many lakes, lower temperatures means lower productivity. Turbidity also interferes with the penetration of light.
