Aquatic biota benthic organisms

Direct penetration of huge amounts of harmful and dangerous substances into the Danube, imperilled its biota and resulted in pestilence of snails and fish, while in the waste water canal of the southern industrial zone of Pancevo town, biota was completely destroyed. This primarily affected benthic organisms, composition and abundance of communities in the localities examined. The consequences were observed at the level of organisms due to their way of life, low mobility and connection with substrate. Some of the pollutants had higher specific gravity than river water and were directly deposited into the sediment. Destruction of the aquatic habitats led to a different extent to decay of individuals, parts of populations and whole communities.
