“…The most frequently used tools considering the different environmental quality evaluation forms of aquatic ecosystems are bioindicators [6,[12][13][14][15], environmental variables [16,17] and landscapes [5,18]. Benthic macroinvertebrates stand out among water quality bioindicators (such as macrophytes, benthic macroinvertebrates, phytoplankton, zooplankton, and fish) due to their ability to reflect environmental alterations over a long-term period through changes in structure and distribution [6,19,20], and therefore they were chosen as biological indicators in this study.…”

Perception of the local community: What is their relationship with environmental quality indicators of reservoirs?

Evaluating the conservation of aquatic ecosystems, especially those which serve to supply, has been carried out using a variety of tools. However, the perception of water quality by the local community which lives in direct contact with water resources has not been considered with enough importance. This study analysed the relationship between the conservation status of reservoirs as perceived by the local community and their conservation status according to physical, chemical, and biological indicators. To do so, we calculated the Trophic State Index (TSI) of the reservoirs, the diversity and richness of benthic macroinvertebrate and we analysed the human influence in the riparian zone. Thus, we created the Community Conservation Perception Index (CCPI) to quantitatively associate the perception of the local community with environmental quality indicators (TSI, diversity, richness and anthropogenic influences in the riparian zone). We found that interviewee perception of reservoir conservation (using the CCPI) was related to trophic state, richness and diversity of benthic macroinvertebrate, and the presence of residences and agriculture in the riparian zone. It is necessary to consider the environmental perception of the local community as a relevant factor in management programmes and the conservation of ecosystems, even if artificial, as is the case with reservoirs. These communities can significantly contribute to maintaining the environmental quality through their performance in participatory management in projects such as: participating in the investigation of pollution in reservoirs, collecting parameters related to water quality, and community action in designing conservation strategies.

“…Bio-remediation of pollutant have been found to be efficienct (Bilal et al, 2016a;Bilal et al, 2016e;Obek and Sasmaz, 2011;Sasmaz, 2008Sasmaz, , 2009Sasmaz et al, 2016a;Obek, 2009, 2012; and the effect on bio-treatment on toxicity have also been studied i.e., the efficiency of the aquatic macrophytes Salvinia auriculata Aublet in purification of polluted effluents, and toxicity was monitored by A. cepa test (2015) (Gonçalves et al, 2015). Three collections were performed in September 2011, the first analysis was performed with water collected directly from River Santa Catarina, Mexico and sampling was performed seven days after the contact of the effluent with the macrophytes, and then after fifteen days.…”

All sorts of pollution on the planet can be traced back to development of industries and the most important among them is water pollution. Clean technologies, management practices and regular monitoring of effluents could be helpful to minimize the contamination of watersheds. Allium cepa (A. cepa) has been recognized as a promising genetic model to detect the toxicity of industrial wastewater, contaminated soil, river water, nuclear contamination and even for those systems which are considered non toxic. A. cepa is distinguished as a low cost test, easy to handle and sensitive to both in vivo and in vitro models. It offers the detection of damages in genetic material quantitatively and the results can be generalized for other biological and ecological systems. Moreover, the pollutants can be classified on the basis of this test present in industrial effluents and their mechanism of action on genetic material. This review focuses on the studies undertaken to evaluate the toxicity of industrial wastewater, contaminated river and soils.
