“…Rivers are natural resources that offer a wide range of ecosystem services from drinking to water utilities in industry, agriculture, transportation and recreation [31,32]. Rivers need have a healthy ecosystem and a good water quality in order to provide these services.…”

“…Rao et al [51] reported that some consequences of sand mining activities like addition of nutrients, changing the ow of water, raising the water temperature and the addition of chemicals can contribute to oxygen depletion in water. Dissolved oxygen (DO) is one of the major parameters used in the determination of water quality [32] and the level is critical to support aquatic biodiversity. CCA showed that dissolved oxygen was one of the major positive factors in uencing the zooplankton community.…”

Certain anthropogenic activities have negative impacts on the aquatic ecosystems. Plankton are sensitive to their environment and are used to monitor anthropogenic impacts. A South-eastern Nigeria River was studied from December 2017 to November 2018 in 6 stations; to assess the plankton community, water quality and anthropogenic impacts. The river was subjected to intense sand mining activities among other activities. The plankton was sampled with filtration method while water was collected and analysed using standard methods. A total of 36 phytoplankton species and 27 zooplankton species were recorded with Chlorophyceae and Rotifers being the most abundant groups. The most abundant species - Melosira granulata (phytoplankton) and Daphnia pulex (zooplankton) are pollution indicators. Some of the physicochemical parameters showed that the river was perturbed by the anthropogenic activities in the watershed. However, the plankton assemblage and community structure gave an indication of a stable environment; though the zooplankton fauna showed some level of stress. The impacts of sand mining activities on water quality and plankton were more in the downstream stations (4–6) where sand mining was intense while perturbation from swimming children and related activities were observed in station 1 especially during the dry season. The presence of eutrophic indicators and tolerant species showed that the river was tending towards eutrophication. Sand mining activities contributed to the nutrient enrichment of the river. CCA showed the major water quality parameters that influenced the plankton community structure. There is need to regulate illegal sand mining activities in the river.

“…The addition of nutrients, changing of flow of water, raising the water temperature and the addition of chemicals are some of the consequences of sand mining activities that could contribute to oxygen depletion in water [36]. Dissolved oxygen (DO) has been described as one of the major parameters used in the evaluation of water quality [37] and the level is necessary to support aquatic biodiversity. [38] reported that dissolved oxygen is essential to support aquatic life and good fish production at levels >5 mg/L.…”

Aquatic ecosystems respond differently to diverse anthropogenic activities in their watersheds. Phytoplankton is sensitive to their environment and is used to monitor anthropogenic impacts. A study was carried out in a South-eastern Nigerian River between December 2017 and November 2018 in 6 stations; to assess the phytoplankton community, water quality, and anthropogenic impacts. Sand mining was a major activity in the river among others. The phytoplankton was sampled with the filtration method while water was collected and analyzed using standard methods. A total of 36 phytoplankton species were recorded with Chlorophyceae being the most abundant group. The most abundant species - Melosira granulata is a pollution indicator. The water quality and phytoplankton structure showed that the water was tending towards eutrophication. This is attributed to the observed anthropogenic activities and cumulative impacts of all the activities in the watershed. The impact of sand mining activities was observed more in the downstream stations (4 – 6) while perturbation from swimming children and related activities was observed in station 1. The community structure reflected the impacts of the activities while CCA showed the major water quality parameters that influenced the phytoplankton community structure.

“…Moreover, chronic exposure to heavy metals for a long time (at even low doses) may cause many types of cancer (Park et al, 2004). It is also known that heavy metals are being discharged into the environment in significant quantities every day ( Aydin et al, 2021; Choudri et al, 2019; Massoudieh et al, 2010; Tokatlı, 2017; Yu et al, 2011; Zhang et al, 2020).…”

In the present study, the spatial–temporal variations of iron, lead, copper, cadmium, mercury, nickel, and zinc accumulations in the water of Şehriban Stream (northern Turkey) were investigated. Water Quality Index (WQI), Heavy Metal Evaluation Index (HEI), Pearson Correlation Index (PCI), and Factor Analysis (FA) were used in analyzing the water quality. Sampling was performed in 12 stations on monthly basis between February 2019 and January 2020 (a hydrological year). The data showed that the Şehriban Stream had significantly high water quality characteristics and the investigated toxicants were not found as dangerous for health. Although there was a slight decrease in the water quality from upstream to downstream, the stream was found to have 1st class water quality in general. As a result of WQI and HEI, although it was determined that the water quality decreased slightly in autumn, the stream was found to be “A Grade – Excellent (<50)” and “Low Contamination (<10),” respectively. As a result of PCI, strong positive correlations were found between almost all the toxicants investigated here (p < 0.01). As a result of FA, 2 factors (“Agriculture – Forestry” and “Rock Structure”) explained 86% of the total variance.
