Abstract: | The quantities of petroleum hydrocarbons being discharged to the Hudson Raritan estuary have been estimated, in tonnes day?1, from data in the literature as: sewage discharges (35), oil refinery discharges (1.3), non-oil refinery industrial discharges (17), oil spills (1.5), atmospheric deposition (0.002), urban and rural run-off (37). Losses have been estimated in a somewhat similar manner as: permanent deposition in sediments (11), dredging (5.8), advection (6.5), bed sedimentary transport (0.007), decomposition in water and sediments (42), evaporation (0.4), movement of surface slicks (0.4). The results are approximate but suggest that petroleum hydrocarbons originate principally from sewage as well as urban and rural run-off and only moderate proportions are discharged through the estuary mouth. However, this discharge combined with that due to dredging spoil disposal operations results in a considerable quantity of petroleum hydrocarbon entering the adjacent New York Bight. |
