英文摘要:
The purpose of this study was to conduct a preliminary assessment of the potential impacts of Atlantic Canadian seafood processing effluents on the aquatic environment through physical-chemical characterization. Shellfish and finfish effluent samples were collected and characterized by biochemical oxygen demand (BOD5), chemical oxygen demand (COD), turbidity, total suspended solids (TSS), ammonia nitrogen (NH3-N), adsorbable organic halides (AOX), soluble BOD5 and soluble COD. Effluent concentration ranges were BOD5 (179 to 276�mg�L−�1), COD (458 to 1717�mg�L−�1), turbidity (28.8 to 88.3�NTU), TSS (27.2 to 120.1�mg�L−�1), NH3-N (1.5 to 12.9�mg�L−�1) and AOX (3.2 and 0.4�mg�L−�1) for flatfish and salmon processing effluents respectively, and cleanup shift AOX (3.5 and 0.5�mg�L−�1). The characteristics of these effluents assessed have the potential to contaminate and degrade receiving water body environments. Improved performance may be possible with further treatment technology optimization on an effluent-specific basis. � 2016 Elsevier Ltd
