@article { , title = {Bioindicators assessing water quality and environmental impacts of water treatment plant sludge.}, abstract = {This study had as objectives to assess water quality using macroinvertebrate communities in Gaviao artificial reservoir (Brazil), used to supply potable water to 2.5 million people, and to evaluate how these organisms responded to the discharge of water treatment sludge into a natural wetland. A total of 1,621 specimens across 23 taxa were identified. Mollusca were the dominant and most frequent group while Insecta presented the most richness. Based on feeding mode, there were more predator organisms than scrapers. The Biological Monitoring Working Party (BMWP') method showed to be more sensible to water quality variations than ASPT index, going from polluted to questionable water quality more frequently. The chemical parameters analysed showed no significant variations and were not a sensitive method for assessing water quality. No organisms could be found downstream of the sludge discharge point, indicating a high impact of sludge disposal on local biota.}, doi = {10.1504/IJESD.2017.10001350}, eissn = {1478-7466}, issn = {1474-6778}, issue = {1}, journal = {International journal of environment and sustainable development}, note = {COMPLETED -- Pub replied to say cannot use VOR as not OA 24/1/2018 LM -- According to ORCID contact has been employed at RGU since Feb 2014 so no exception available. 22/1/2018 LM -- Chased AAM with contact, but also emailed support@inderscience.com to check to see if could use VOR access on their website to this issue is FREE 16/1/2018 LM -- Requested doc 18/12/2017 LM -- Info via WoS alert 13/12/2017 LM ADDITIONAL INFORMATION: Pestana, Carlos -- Panel B}, pages = {25-42}, publicationstatus = {Published}, publisher = {Inderscience}, url = {http://hdl.handle.net/10059/2677}, volume = {16}, keyword = {Macroinvertebrates, Bioindicators, Artificial reservoir, Water quality, Water treatment sludge}, year = {2017}, author = {Alves Abreu da Costa, Talitha R. and Weber, Olmar Baller and Pestana, Carlos J. and Capelo-Neto, José} }
