Seasonal determination of heavy metals in muscle, gill and
Aquatic biota is contaminated with heavy metals as a result of anthropogenic activities and industrialization. Heavy metals, that is copper (Cu), chromium (Cr), lead (Pb) and zinc (Zn), were analysed in Oreochromis niloticus collected from the Gomti River at Lucknow and Jaunpur sites, India, from 2011 to 2012. Accumulation of heavy metals was estimated in different tissues of tilapia.

Copper Alloys
Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion. The best known traditional types are bronze, where tin is a significant addition, and brass, using zinc instead. Both these are imprecise terms, both having been commonly referred to as lattens in the past.
