“…The survival, composition, diversity, behaviour, and physiology of aquatic organisms are in uenced by dissolved oxygen (Onyena et al, 2021). Dissolved oxygen levels in all study stations ranged from 1.03 to 5.72 mg/l (Table 3) and the mean dissolved oxygen value of 4.14 ± 1.59 mg/L, was less than the WHO standard of 6 mg/L.…”

Drinking water quality is a critical factor affecting human health particularly in natural resource-dependent countries including Nigeria. Hydrocarbon related pollution, mining waste, microbial load, industrial discharge and other anthropogenic stressors degrade drinking water quality in coastal communities and pose serious public health and ecological risks. This study evaluated the physicochemical properties of drinking water in selected communities (Okerenkoko, Kurutie and Oporoza) in Gbaramatu Kingdom, in the Niger Delta region of Nigeria, to assess the water quality using the water quality index (WQI) and pollution models. Nitrate, chromium, cadmium, copper, lead, aluminium, pH, total hardness, total dissolved solids, cyanide and residual chlorine were measured in twelve selected locations across three communities. WQI results of 139 to 44180 indicated that analyzed water samples exceeded the critical WQI value of 100, in addition the mean pH of the water samples recorded 8.11 ± 0.32, indicating unsuitability for consumption. Nickel ranging from 0.014 to 0.176 mg/L and residual chlorine 11.6 to 7407 mg/L were the major contributors to the degradation of water quality and exceeded the WHO recommended limit of 0.02 and 0.25 respectively. While groundwater had better organoleptic properties compared to surface and rain water, the geo-accumulation index showed that water sources vary from moderately to heavily contaminated with Ni and Cd. The WQI and pollution model results indicate that immediate action is required by stakeholders to address water quality deterioration (e.g., providing alternative water supply) as existing water resources in the area pose significant health risks to the local population.

“…In this study, deposit-feeding detritus consumers, usually known as detritivores, mostly included the anellids Oligochaeta and Polychaeta (mostly Capitellidae and Spionidae). Both taxa are opportunistic feeders, well-adapted to degraded aquatic habitats, such as estuaries and lagoons [62,63], due to organic pollution or eutrophication [61,64,65].…”

“…The ECELS index is based on 5 components: littoral morphology, human activity, water characteristics, emergent vegetation and hydrophytic vegetation [36]. The index can range from 0 to 100, divided into 5 categories: bad (<30), poor (30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45)(46)(47)(48)(49), moderate (50)(51)(52)(53)(54)(55)(56)(57)(58)(59)(60)(61)(62)(63)(64)(65)(66)(67)(68)(69), good (70-89) and high (≥90). Since the values of CDI increase at high disturbance, while the ECELS indices decreased (or vice versa), we inverted the ECELS values before calculating the Integrated Disturbance Index (IDI), following Ligeiro et al [35].…”

Coastal wetlands are suffering from anthropogenic alterations worldwide. Aquatic monitoring based on macroinvertebrates has been successfully used to assess the ecological condition of many aquatic systems worldwide. Nonetheless, studies are still insufficient for the coastal wetlands of the South Pacific. Here, we present a preliminary attempt to select metrics based on aquatic macroinvertebrates to incorporate into coastal wetlands biomonitoring in the Chilean Mediterranean ecoregion. We sampled 25 sites in ten coastal wetlands during the austral spring of 2019. We used an integrated index that considers both human activities at catchment and at local scales to identify sites less or more disturbed. We tested a total of 70 metrics (either traditional or new metrics) representing different aspects of community structure/composition, functions and tolerance to pollution. Two metrics were finally retained: detritivore abundance (traditional metric) and geometric mean body size (new metric). These metrics were able to detect sites impacted by human activities. Thus, they might be considered as candidate metrics for the biomonitoring of these systems and to develop future indices. Moreover, because of their generality, they might also be applicable to coastal wetlands in other Mediterranean regions, including sites where taxonomic identification is still a challenge.
