Abstract:
The subsequent chapters of the Thesis deal with the toxic
effects of mercury, copper, zinc und~1ead on these bivalve
molluecs, their accumulation and distribution among various
organs of the animals and also the motel retention winstica
by the three species. Static biousauy tests have been conducted
in these studies. It was found that the concentrations of
the various metals studied in these organism are well below
the permitted level given far ease ahellfienes (crab and ehrimgi
and that these maliuscs are very good integrators ef trace
metals from their environment and may be used as an indicator
organism sf metal pallutaute.
The present investigutionsemphaeie the need for a clean
coastal water and gives a serious warning regarding the possiblc
route of heavy metals in ta human body thraugh marine food
