Since the industrial revolution in the late eighteenth century, the world has discovered new sources of pollution nearly every day. So, air and water can potentially become polluted everywhere. Little is known about changes in pollution rates. The increase in water-related diseases provides a real assessment of the degree of pollution in the environment. This chapter summarizes water quality parameters from an ecological perspective not only for humans but also for other living things.
W ater quality is measured by several factors, such as the concentration of dissolved oxygen, bacteria levels, the amount of salt or salinity , or the amount of material suspended in the water turbidity. In some bodies of water, the concentration of microscopic algae and quantities of pesticides, herbicides, heavy metals, and other contaminants may also be measured to determine water quality. Poor water quality can pose a health risk for people. Poor water quality can also pose a health risk for ecosystems. In the Florida Keys, good water quality is essential to a healthy marine ecosystem. Seagrass and coral reef communities thrive in clean water that is relatively low in nutrients.
Water quality relating to dissolved salts is usually expressed as the conductivity (S/cm) or more commonly, when discussing water purity, by its reciprocal, the.
