Stream water chemistry were analyzed across Vatinsky Egan River Catchment (West Siberia). The objective of the study is to reveal the spatial and seasonal variations of the water quality and to assess the anthropogenic chemical inputs into the river system. Stream chemistry were monitored in 24 sampling sites for a period extended from January 2002 to December 2005. Spatial distribution of constituents in the Vatinsky Egan River basin indicated pollution from non-point sources associated with oil development. Data revealed that ion concentrations of river waters are usually negatively correlated with stream discharge. The major spatial variations of the hydrochemistry are related to the salinity. Chloride exhibited wide and high concentration range. A comparison with another rivers of West Siberia reveals that Vatinsky Egan River is the most saline and regional impacts further out in the watershed. The salinity of the river water increases substantially as it crosses Samotlor oil field. Many Cl(-) concentrations in the middle and lower parts of the catchment exceed the world average river values by one or more orders of magnitude. For 38% of sampling events, total petroleum hydrocarbons (TPH) concentrations were above the recommended water quality standards.
对瓦廷斯基伊根河流域（西西伯利亚）的溪流水化学进行了分析。该研究的目的是揭示水质的空间和季节变化，并评估河流系统中的人为化学输入。在24个采样点对溪流水化学进行了监测，监测期从2002年1月延长至2005年12月。瓦廷斯基伊根河流域成分的空间分布表明存在与石油开发相关的非点源污染。数据显示，河水的离子浓度通常与溪流流量呈负相关。水化学的主要空间变化与盐度有关。氯化物呈现出广泛且高浓度的范围。与西西伯利亚的其他河流相比，发现瓦廷斯基伊根河是盐分最高的，且流域内的区域影响更远。河水的盐度在流经萨莫特洛尔油田时大幅增加。集水区中下游的许多氯离子浓度超过世界平均河流值一个或多个数量级。在38%的采样事件中，总石油烃（TPH）浓度高于推荐的水质标准。
