“…CCO meets globally the requirements described by Borja and Dauer (2008) for environmental indicators following the DPSIR (drivers-pressures-state changes-impacts-responses) approach (Elliott, 2002;Atkins et al, 2011). To assess the sensitivity and uncertainty versus the inherent variability of the index (Borja et al, 2013), further sampling cycles will be probably necessary in the future. The pertinence of the sub-BQE intertidal macroalgae and the representativeness of sampling sites in corresponding water bodies must be taken into consideration.…”

International audienceAn index CCO (cover, characteristic species, opportunistic species) has been developed for the implementation of the European Water Framework Directory (WFD) in coastal waters, using intertidal macroalgal communities as bio-indicator (Biological Quality Element). CCO is based on the calculation of three metrics corresponding to the global cover of macroalgal communities (metric 1), the number of characteristic species per topographic level/seaweed community (metric 2) and the cover of opportunistic species (metric 3). The final rating is obtained by pooling the scores of the three metrics. Results are given for 32 sites in 29 water bodies, grouped into four biogeographic regions along the Channel–Atlantic coasts of France. Over the six-year study, most of sites were sampled twice each (every three years). CCO index revealed that 25 coastal water bodies of both the Channel and the Bay of Biscay were in good or high ecological quality status (EQS), whereas only 4 of them were moderate and none in poor to bad status. However, significant differences have been found between sites and between geographic regions, water bodies located in Brittany obtaining the best EQS. No significant change occurred between the three-year sampling sets. A significant correlation has been established between a three-component anthropogenic pressure index and CCO ratings, showing the accuracy of CCO to evaluate the impact of anthropic activities on the structure and development of macroalgal communities as indicator of the ecological quality of coastal water bodies

“…Aquatic environment studied (A), and temporal trend in number of paper for each aquatic environment (B). Dimitriou et al, 2012;Borja et al, 2013). Many countries such as China and India are concerned because they are either facing water scarcity or the prospect of future scarcity, which would lead to food scarcity and endanger the public water supply Wu et al, 2012).…”

Aim: Water quality has been the subject of many recent studies, moreover, the physical, chemical and biological parameters of water are used to investigate water quality and can be combined into a single index, the Water Quality Index (WQI), for use by water resource managers and the general public. The aim of this study was to use scientometrics to evaluate how water quality has been addressed in the international scientific literature. Method: For the quantitative analysis of the publications on WQI, we used the search database SCOPUS (http://www.scopus.com). The search was performed using the words "QUALIT* WATER* INDEX*" in papers published in all databases (through 2011). Results: We found 554 articles that dealt with the use of WQI the number of publications has increased significantly over the last 20 years. India had the most studies, with 177 articles, followed by China, Brazil and the United States. These four countries together published 57% of studies on WQI. We generated 15 linear models to explain the number of publication by study sit (country). According to the Akaike Information Criterion (AIC), the best model to explain the number of publications by country was the model that combined Sanitation and Public Supply. Conclusion: Finally, this paper presents the state of scientific literature on WQI and demonstrates the growing interest of the scientific community in this issue, which is certainly due to the importance of the quantity and quality of water for human supply, economics, health and the conservation of water resources.Keywords: scientometrics, river, stream, NSF, sanitation, water supply.Resumo: Objetivo: A qualidade da água tem sido objeto de muitos estudos recentes, além disso, os parâmetros físicos, químicos e biológicos da água são usados para investigar a qualidade da água e podem ser combinados em um único índice, um Índice de Qualidade de Água (IQA), para uso de recursos hídricos gestores e público em geral. O objetivo deste estudo foi utilizar a cienciometria para avaliar como a qualidade da água tem sido abordada na literatura científica internacional. Método: Para a análise quantitativa das publicações sobre IQA, foi utilizada a pesquisa de banco de dados SCOPUS (http://www.scopus.com). A pesquisa foi realizada utilizando as palavras "QUALIT* WATER* INDEX*", em artigos publicados em todos os bancos de dados (até 2011). Resultado: Encontramos 554 artigos que tratavam do uso de IQA, e o número de publicações aumentou significativamente ao longo dos últimos 20 anos. A Índia teve o maior número de estudos, com 177 artigos, seguidos por China, Brasil e Estados Unidos. Esses quatro países juntos publicados 57% dos estudos sobre IQA. Geramos 15 modelos lineares para explicar o número de publicação de estudo por país. De acordo com o Critério de Informação de Akaike (AIC), o melhor modelo para explicar o número de publicações por país foi o modelo que combinou Saneamento e Abastecimento Público. Discussão: Finalmente, este trabalho apresenta o estado da literatura científica...

“…Moreover, because the assessment uncertainty of most national methods was not quantified, there was no way to evaluate if adjustments were justified with regard to the inherent error of the methods. Progress has been made in recent years however, regarding the quantification of uncertainty, e.g., for phytoplankton (Carvalho et al, 2013), phytobenthos (Kelly et al, 2009), macroalgae (Mascaró et al, 2013), and fishes (Borja et al, 2013b).…”
