Sediments
can be made toxic in areas where there is considerable deposition
of organic matter. This is assessed by measuring TOC.
The pie graph shows the proportion of the
Barnegat Estuary that is good (green), fair (yellow), poor (red)
or missing data (blue) for sediment total organic carbon (TOC). The small symbols on the map show the rating
at a particular sampling location.
