Dilution and dispersal calculations were used to analyze the effect of the seawater scrubber's effluent on the pH, O~ concentration, and heavy metal levels of the Oslofjord. Results suggested that surface discharge would lower the pH by 0.5 in large areas and deep water discharge would seriously increase the COD; however, lime treat- ment of the effluent in the first case and aeration in the second would considerably reduce the hazard. The potential increase of heavy metals could not really be determined, but was judged to pose only small problems. (sir)

Within the record period, spills of vegetable oils at Vancouver Harbor have caused greater bird losses than petroleum spills. Vegetable oils cause feather wetting but do not exhibit odor and slick

characteristics of petroleum oils. Because most are edible, their potential harm may go unnoticed; storage and shipment of vegetable oils may be overlooked in oil spill contingency planning. Department of Environment, Canadian Wildlife Service, Box 340, Delta, British Columbia, Canada V4K 3Y3.

to assess environmental pollution levels of Masan Bay [Korea]. (In Korean; English sum- mary.) J. oceanol. Soc. Korea, 14(1): 15-25.

Bioassays on 4 commercially important shellfish revealed highest mortality among Mytilus edulis (100% after 120 hours at one station), lowest among Tapes japonica. Water quality analysis showed severe pollution in the inner bay with high levels of ammonia, COD and SS, and lack of dissolved oxygen. Increased pollution led to a decrease in diatoms and an increase in dinoflagellates. In the inner bay, 4% of the standing' crop was diatoms while 96% (94% Prorocentrum micans, known to be pollution-tolerant) was dinoflagellates. In the out- er bay, 80% of the phytoplankton was diatoms; 20%, dinoflagellates. Fisheries Research and Development Agency, Busan, Korea. (slr)
