The
Central Pollution Control Board estimated the total waste generation in
the coastal regions of our state and published it during 1996. (Series.COPOS/9/1995/96).
It was reported that the total solid waste generated in the coastal areas
is to the tune of 7,191 tonnes per day. While the effluents generated
are 24,66,114 m3 /day which includes 21,16,136 m3/pay from the aquafarms.
Once
the discharges enter the wetland area they are partially filtered by the
wetlands. The magnitude of this filtering depends on the size of the wetland.
Where there are no wetlands the pollutants are discharged directly into
the lagoon cells and further into the shelf water cells. In addition oil
is discharged from the shipping and oil related industries resulting in
pollution and bioaccummulation of heavy metals and synthetic compounds.
