investigating the effects of desalination effluent on the physical and chemical factors of sea ‎water and macrobenthic communities (norwejhe desalination plant, bandar shirino)‎

in this study, the effects of salinity pollution and temperature of the effluent of the norwegian ‎desalination plant on the physicochemical factors of sea water and ‎macrobenthic communities were investigated. among the physical and chemical factors, the most changes ‎were related to salinity and temperature and were measured between stations 1 and 8 (p<0.05). ‎in the cold season, the salinity and temperature at station 1 (freshwater effluent outlet) were ‎‎38.67±0.32 ppt and 23±0.58 °c, respectively, and at station 8 (control point), 0.78 ppt. 35.67 ± ‎‎19.33 ± 0.21 degrees celsius and in the hot season, the salinity and temperature in station 1 were ‎‎36.33 ± 0.60 ppt and 31.67 ± 0.17 degrees celsius, respectively, and 40.67±0.23 ppt and ‎‎35.67±0.10 °c were measured at station 8. in this study, the predominance was with amphipoda ‎in summer and isopoda in winter. pearson's correlation showed a negative and significant ‎relationship between the density of macrobenthos with salinity and temperature. the diversity ‎index in station 1 was the lowest compared to the reference station. the findings of this study ‎show the effect of desalination wastewater discharge on the physical and chemical characteristics ‎of water and the population of macrobenthos. among the investigated parameters, salinity and ‎temperature were the most effective influencing parameters, which decreased with the distance ‎from the wastewater discharge site.‎
