So, in many countries it is the object of numerous environmental laws and regulations. This relates not only to drinking water but ultimately also for the whole water cycle, for example surface and ground water, process and waste water.
WebChlorophyll is a green pigment found in plant cells, algae cells, and cyanobacteria. The primary function of chlorophyll molecules is radiation absorption, which provides energy essential for photosynthesis. Hand-held chlorophyll meters typically provide a relative indication of chlorophyll in plant leaves.
