Temperature, pH and trace elements (F, P, Cr, Cu, Zn, Cd, and Pb) contents were determined in 16 stations as well as in 2 industrial and 2 domestic discharge sources, in the central coastal area of the Gulf of Gabes. Compared to the northern and southern areas of the study area, the highest contents of contaminants were reached in the central area which hosts the coastal industrial complex. The seawater in this central area was also found to be acid and of higher temperature. Based on the Water Pollution Index results, an increasing degradation gradient of the seawater quality was revealed from northern and/or southern stations to central ones, categorized as 'strongly to seriously affected'. Phosphogypsum wastes dumped by the Tunisian Chemical Group (GCT) seem to have continuously degraded the seawater quality in the study area. A rapid intervention is needed to stop the effects on the marine environment.
在加贝斯湾中部沿海地区的 16 个站位以及 2 个工业和 2 个生活排污口采集了水样，测定了温度、pH 值和微量元素（F、P、Cr、Cu、Zn、Cd 和 Pb）的含量。与研究区域的北部和南部相比，污染物含量最高的是沿海工业综合体所在的中部地区。该地区的海水呈酸性，温度也较高。根据水污染指数的结果，从北部和/或南部站位到中部站位，海水水质的退化程度逐渐增加，被归类为“严重到极强影响”。突尼斯化工集团（GCT）倾倒的磷石膏废物似乎持续降低了研究区域的海水水质。需要采取快速干预措施来阻止对海洋环境的影响。
