This study provides data for total and non-residual vanadium distributions in the northern Saronikos Gulf and shows that close to the Athens sewage outfall (ASO), the combined domestic and industrial wastes have resulted in a considerable increase in concentrations of vanadium in sediments and suspended solids. This appears to be the main vanadium source in the area; a second major source is a fertilizer plant (FP) near the entrance of Piraeus Harbour (PH), the impact of which is also important. Atmospheric inputs from the Piraeus industrial site and frequent crude oil spillages from ships and land-based sources seem to contribute significantly to the observed vanadium distribution, which is clearly affected by the prevailing circulation of surface waters and winds. The high percentage of the 0.5 NHCl-leachable vanadium fraction in the most polluted sediments, together with positive correlation with organic carbon and certain other trace metals (i.e. Ag, Co, Cr, Fe, Zn) and negative correlation coefficients with Al and Sc, indicate that a considerable portion of the vanadium is of "anthropogenic" origin not related to lithogenous particles. It enters the system in association with relatively large organic aggregates, either authigenic or derived from sewage.
本研究提供了萨罗尼科斯湾北部钒的总量和非残留分布数据,并表明在靠近雅典污水排放口(ASO)处,生活和工业废物的混合排放导致沉积物和悬浮固体中钒的浓度显著增加。这似乎是该地区钒的主要来源;第二个主要来源是比雷埃夫斯港(PH)入口附近的一家化肥厂(FP),其影响也很重要。比雷埃夫斯工业场地的大气输入以及船舶和陆源频繁的原油泄漏似乎对观测到的钒分布有显著贡献,而钒分布明显受到表层水和风向的主导环流影响。在污染最严重的沉积物中,0.5N HCl可浸出钒组分的比例较高,且与有机碳及某些其他痕量金属(即Ag、Co、Cr、Fe、Zn)呈正相关,与Al和Sc呈负相关系数,这表明相当一部分钒来自与陆源颗粒无关的“人为”来源。它与相对较大的有机聚集体结合进入系统,这些聚集体要么是自生的,要么来自污水。
