This work assesses potential physicochemical, metallic, and radiological contamination of liquid discharges from the phosphoric acid (PA) production unit at the coast of El Jadida Province in Morocco. The physicochemical parameters: pH, conductivity, salinity, turbidity, total hardness, nitrate, nitrite, orthophosphate, and heavy metals were analyzed in PA and beach samples. ²³⁸U, ²³²Th, and ²²⁶Ra were determined by gamma spectrometry, the Radon contents were determined using solid state detectors (LR-115). It is concluded that phosphate effluents are strongly acidic with a mean pH-value of 1.8 and that the discharges still contain relatively high levels of fluoride, phosphorus and radiological substances.

这项工作评估了摩洛哥杰迪代省海岸磷酸 (PA) 生产装置液体排放物的潜在物理化学、金属和放射性污染。对 PA 和海滩样品中的物理化学参数：pH、电导率、盐度、浊度、总硬度、硝酸盐、亚硝酸盐、正磷酸盐和重金属进行了分析。²³⁸ U、²³² Th 和²²⁶ Ra 采用伽马能谱法测定，氡气含量采用固态检测器（LR-115）测定。结论是，磷酸盐废水呈强酸性，平均pH值为1.8，排放物中氟化物、磷和放射性物质的含量仍较高。
