The spatial-temporal variation in crustacean assemblages of the Odiel-Tinto estuary, one of the most polluted areas in the world, was studied in 2000, 2002 and 2004. The crustacean assemblages were mainly established according to the natural gradient from estuarine to marine environment (based on water and sediment characteristics such as dissolved oxygen, salinity, granulometry or organic content). Pollutants such as copper, zinc or phosphates could also explain partially this pattern based on BIOENV and canonical correspondence analyses. However, there were clear symptoms of perturbation, mainly in the inner areas, such as a low number of species and a low abundance, especially in relation to the typical estuarine species (e.g. Cyathura carinata, Corophium spp.). This study provides baseline information which can be used as a reference point in a long-term perspective.
2000 年、2002 年和 2004 年，研究了世界上污染最严重的地区之一——奥德耶尔-廷托河口的甲壳类动物群的时空变化。甲壳类动物群主要是根据从河口到海洋环境的自然梯度建立的（基于溶解氧、盐度、粒度或有机含量等水和沉积物特征）。根据 BIOENV 和典范对应分析，铜、锌或磷酸盐等污染物也可以部分解释这种模式。然而，在内区存在明显的干扰迹象，例如物种数量少、丰度低，特别是与典型的河口物种（例如 Cyathura carinata、Corophium spp.）相比。本研究提供了基线信息，可以作为长期参考点。
