Serpentine subgroup (part of the kaolinite-serpentine group in the category of phyllosilicates) [1] are greenish, brownish, or spotted minerals commonly found in serpentinite. They are used as a source of magnesium and asbestos , and as decorative stone. [ 5 ]
Soil with serpentine is poor in calcium and other major plant nutrients, but rich in elements toxic to plants such as chromium and nickel. [20] Some species of plants, such as Clarkia franciscana and certain species of manzanita , are adapted to living on serpentinite outcrops .
Nutrient pollution, a form of water pollution, refers to contamination by excessive inputs of nutrients.It is a primary cause of eutrophication of surface waters (lakes, rivers and coastal waters), in which excess nutrients, usually nitrogen or phosphorus, stimulate algal growth. [1]
Symphyotrichum depauperatum (formerly Aster depauperatus), commonly known as serpentine aster or starved aster, [4] [5] is a rare species in the family Asteraceae adapted to serpentine barrens, an ecosystem with a high concentration of toxic metals in the soil.

Plants are exposed to toxic metals through the uptake of water; animals eat these plants; ingestion of plant- and animal-based foods are the largest sources of toxic metals in humans. [32] Absorption through skin contact, for example from contact with soil, or metal containing toys and jewelry, [ 33 ] is another potential source of toxic metal ...
