COMPARATIVE ANALYSIS OF HEAVY METALS AND ELEMENTAL PROFILES IN TROUT SPECIES FROM TWO DIFFERENT AREAS.

An important concern of man has become to have high-quality food for a healthy life. Fish such as rainbow trout (Oncorhynchus mykiss) and brook trout (Salvelinus fontinalis) are an important bioindicator of pollution. The accumulation of heavy metals represents a potential danger to public health. Trout is preferred and consumed by many people so any possible risk of ingesting metals through food chains should be assessed. The main organs studied according to specialized literature regarding the accumulation of heavy metals are the liver an the kidney, these organs play an important role in preventing the transfer of heavy metals to other organs, for example muscle tissue. As is known, the pollution of aquatic ecosystems has a direct impact on the entire aquaculture activity. Therefore, the purpose of this study was to monitor metals present in the two trout species in different areas. [ABSTRACT FROM AUTHOR]
