Water Quality Parameters


What is Chlorophyll (CHL)?

Chlorophyll does much more than make plants green; in fact, it is a critical component of photosynthesis, a process by which plants create their own food. Photosynthesis both sustains plant life and produces oxygen. Chlorophyll in a plant absorbs light and uses the energy to convert carbon dioxide and water into glucose. Plants use the glucose together with nutrients to make new plants. This process produces oxygen which is then released by the plant.

How and Why is CHL Measured in Water?

Much like its terrestrial counterparts, algae’s growth within water is contingent upon successful photosynthesis. CHL provides a reliable metric by which to monitor algal growth. By understanding algal growth, researchers gain essential insights into the trophic activities taking place in water bodies.

CHL is an indication of how much phytoplankton is in the water. Phytoplankton are at the base of the food web in the ocean.  When phytoplankton levels are too low, the food web is broken and other life in the water may not survive. Conversely, when phytoplankton levels are too high, sunlight can be blocked and some marine life can be smothered. 

PME manufactures several devices capable of monitoring CHL.
