ABSTRACT
Mex Bay has flushing time rangi~ fro- 1.1 day in
winter and 2.8 day In summer. Mass helenee estilet.s of S~
trace metals (Pb, Cd aid Hg) in the Bay revealed that the
net seaward fl,uxta of Pb end Cd are cOf’siderably higher thllln
the metel. Inputs from umum and chloralkall effluents. For
II; the net seowerd ftu,'( i. c~retively smeller than that
auppl ied by the effl~t8. Thie suggeste the i~rtance of
other sources end sinks In the mess balance forMUlations of
these metals. Th~ mean concentrations of the total Pb, Cd
and ~; In the Bey wGters do not SeeM, until now, to reach
the levele that threaten the living organiSMS existing In
this area.
