“…The natural gradients in salinity, granulometry and organic content have been described as the most important factors to explain the distribution and abundance of macrobenthic community in numerous estuarine ecosystems (Wolff 1983;Warwick et al 1991;Attrill et al 1996;Rakocinski et al 1997;Ysebaert et al 2002;Mucha et al 2003;Sousa et al 2006). In general, The Tinto-Odiel system has shown typical water and sediment characteristics of estuarine areas at the spatial scale.…”

“…Independently of sampling year, the structure of the community has been mainly determined by granulometry and the organic matter content in sediment, which are considered as the major structuring factors for the natural macrobenthic distribution pattern together with salinity (Warwick et al 1991;Ysebaert et al 2002;Mucha et al 2003;Sousa et al 2006). Community variables such as Shannon Diversity or taxa number showed the typical trend of estuaries, with a progressive increment towards the mouth river, but in a wide interval (e.g., H'= 0.96 and only 2 families at O1 until H'= 2.84 and 46 families at C4), which seem to demonstrate a strong stress on communities, at least at inner areas.…”

“…Sediments contaminated with heavy metals have been found to enter aquatic environments via several pathways, including atmospheric deposition, industrial activities and agricultural activities [5][6][7][8]. When compared with the previous two pathways, agricultural activities are known to be significant non-point sources of heavy metals in the environment [9,10].…”

“…The dissected parts were pooled into eight different parts namely; scales, muscle, bone, gills, operculum, intestine, liver and cartilage. All the eight parts were dried at 80˚C according to [16] ( Mucha et al, 2003) until a constant dry weight.…”
