“…Electrical conductivity and concentration of total dissolved solids, associated with anthropogenic impacts such as organic enrichment [46] and soil erosion [47], are two important variables in the structure of the aquatic community [46,48]. Measures of these two variables in two streams with high HII score (Taq8 and Taq9) were high, but there was no correlation with the biological metrics used.…”

Generally, aquatic communities reflect the effects of anthropogenic changes such as deforestation or organic pollution. The Cerrado stands among the most threatened ecosystems by human activities in Brazil. In order to evaluate the ecological integrity of the streams in a preserved watershed in the Northern Cerrado biome corresponding to a mosaic of ecosystems in transition to the Amazonia biome in Brazil, biological metrics related to diversity, structure, and sensitivity of aquatic macroinvertebrates were calculated. Sampling included collections along stretches of 200 m of nine streams and measurements of abiotic variables (temperature, electrical conductivity, pH, total dissolved solids, dissolved oxygen, and discharge) and the Index of Habitat Integrity (HII). The values of the abiotic variables and the HII indicated that most of the streams have good ecological integrity, due to high oxygen levels and low concentrations of dissolved solids and electric conductivity. Two streams showed altered HII scores mainly related to small dams for recreational and domestic use, use of Cerrado natural pasture for cattle raising, and spot deforestation in bathing areas. However, this finding is not reflected in the biological metrics that were used. Considering all nine streams, only two showed satisfactory ecological quality (measured by Biological Monitoring Working Party (BMWP), total richness, and EPT (Ephemeroptera, Plecoptera, and Trichoptera) richness), only one of which had a low HII score. These results indicate that punctual measures of abiotic parameters do not reveal the long-term impacts of anthropic activities in these streams, including related fire management of pasture that annually alters the vegetation matrix and may act as a disturbance for the macroinvertebrate communities. Due to this, biomonitoring of low order streams in Cerrado ecosystems of the Northern Central Brazil by different biotic metrics and also physical attributes of the riparian zone such as HII is recommended for the monitoring and control of anthropic impacts on aquatic communities.

“…Values of pH and turbidity were also highest in altered and impacted areas, with lowest RHDI scores, associated with increasing discharge of domestic effluents, since these variables are influenced by the transport and leaching of allochthonous materials (Gholizadeh et al, 2016), especially with urbanization (Menezes et al, 2016). Dumping of solid waste, sewage runoff and storm water exfiltration is common along the Cereja River (Guimarães et al, 2009;Monteiro et al, 2011;Sousa et al, 2016) and much of this enters the stream, especially in the rainy season, elevating dissolved salts and nutrient concentrations (Daniel et al, 2002;Nascimento et al, 2015).…”

“…In Amazon streams, conductivity, pH and turbidity are normally low (Batalha et al, 2014;Bertaso et al, 2015;de Paiva et al, 2017), due to rapid leaching of organic matter and acids and rapid absorption and recycling of nutrients in the riparian forest (Oliveira et al, 2009;Lopes and Magalhães, 2010;Brejão et al, 2021). The increase in conductivity, pH and turbidity from natural areas to impacted areas in the Cereja River is considered harmful to the macroinvertebrate community and may modify biological processes and interfere in aquatic photosynthetic processes (Nascimento et al, 2015).…”

Rich freshwater biodiversity is threatened by increasing deforestation and disorderly urbanization throughout the Brazilian Amazon, especially in streams and creeks, leading to loss of aquatic habitats. Biological information combined with habitat and water quality are effective tools for rapid assessment. The impact of increasing urbanization was assessed in the Cereja River, eastern Amazonia using a Riparian Habitat Diversity Index (RHDI), benthic macroinvertebrate structure and water and sediment variables in ten areas along the Cereja using multivariate analyzes. Increasing urbanization is associated with lower RHDI, abundance, diversity and equity of benthic macroinvertebrates, higher conductivity, pH, temperature, width and percentage gravel. This information is useful for rapid identification of impacts, assessment of recovery of degraded areas and maintenance of non-degraded areas along urban streams.

“…In that case, there are numerous examples, such as mining. In it, trace metals can disperse and sediment in freshwater or marine aquatic environments and influence changes in electrical conductivity (NASCIMENTO et al, 2015;ROUABHI, 2020).…”

Water quality, currently determined through laboratory analysis, can also be determined by the presence or absence of bioindicators sensitive to climate change, and these relationships can be the subject of studies in Environmental Education. The objective of this integrative analysis was to identify the existing gaps in physical-chemical and microbiological analyses, the use of biomonitors, the insertion of climate change and the role of Environmental Education as a fundamental complement to these analyses in the Pará Amazon, especially in the municipality of Paragominas. The secondary data were obtained from academic literatures published between 1997 and 2022, the year in which the National Water Resources Policy turns 25 years old. The data obtained and analyzed indicated that the research on water quality in the Pará Amazon, uses physical-chemical parameters, and compares the laboratory data obtained with the values established in Resolution No. 357/2005. The use of these parameters associated with aquatic bioindicators in Paragominas already presents data directed, with greater frequency, to the Uraim River, igarapé 54 and seven, which leaves a gap as to the Paragominas/Prainha River, which is a receptor of urban effluents and a tributary of the right bank of the Uraim; there are other gaps such as: scarcity of research regarding water quality and climate change are scarce; Environmental Education, although the municipality already has a plan for this, is still only applied in formal education spaces in lower and upper elementary school, but is not applied to users of water resources, which leaves them at the margins of this process. Therefore, these gaps become difficulties in the correct and active application of the NWRP.
