“…The behavior and ecological characteristics of the grey mullet ( Mugil cephalus ) species makes it suitable for the monitoring of marine coastal metal pollution [ 17 , 18 , 19 ]. Grey mullet is a bottom-dwelling species that feeds on detritus, microscopic invertebrates, and algae [ 2 , 20 ], and it is known to accumulate a high level of heavy metals in its organs from the surrounding environment [ 21 ].…”

The environmental monitoring of chemical toxicants has been a widely studied topic in the last few decades. The main aim of the present study was to determine the total concentration of nine elements (Cd, Cr, Pb, Ni, Al, Cu, Fe, Mn, and Zn) in the fish species grey mullet (M. cephalus) and in the coastal marine waters collected from various sampling points along the Black Sea (Bulgaria) and the Ionian Sea (Italy). Further, those results were applied to predict the pollution degree in those coastal marine environments. The fish samples were subject to acid digestion followed by appropriate analytical determination. The metal concentrations in marine water samples collected from the Black Sea (Bulgaria) and the Ionian Sea (Italy) were also analyzed. Unpaired Student’s t-test and the one-way ANOVA were applied for the statistical analysis of the data. The statistical results revealed a significant variation (p < 0.0001) in the concentration of various fish tissues. The accumulation of toxic and essential elements differs significantly in grey mullet species caught from the Black Sea (Bulgaria) and the Ionian Sea (Italy). The results from this study may serve as a convenient approach during marine pollution programs set by both countries (Italy and Bulgaria).

“…Consequently, the south-south and south-west have abundant surface and groundwater, and annual rainfall is high. Specifically, the major sources of water in the south-south are creeks, rivers, shallow wells and boreholes; and studies of water quality in this part have been tailored to them ( Ihunwo et al., 2020 ; Ocheli et al., 2020 ; Owamah, 2020 ; Owoyemi et al., 2019 ). Similarly, studies in the south-west have been related to several rivers, lagoons, groundwaters, lake and stream, as these are abundant ( Ebele et al., 2020 ; Ezemonye et al., 2019 ; Gbadebo, 2020 ; Odukoya et al., 2017 ; Ogunbanwo et al., 2020 ).…”

“…To illustrate, PTEs such as As, Cd, Hg, and Pb have no health benefits when ingested through drinking water; rather, they are associated with cardiovascular disorders, renal injuries, and cancer risk in humans ( Yao et al., 2021 ). Also, they can induce neurotoxicity, oxidative stress, and alter immune systems in aquatic animals ( Ihunwo et al., 2020 ).…”

The appropriate acquisition and processing of water quality data are crucial for water resource management. As such, published articles on water quality monitoring and assessment are meant to convey essential and reliable information to water quality experts, decision-makers, researchers, students, and the public. The implication is that such information must emanate from data obtained and analysed in an up-to-date, scientifically sound manner. Thus, inappropriate data analysis and reporting techniques could yield misleading results and mar the endeavours of achieving error-free conclusions. This study utilises the findings on water quality assessment in Nigeria over the last 20 years to reveal the likely trends in water quality research regarding data collection, data analysis, and reporting for physicochemical, bacteriological parameters, and trace organics. A total of 123 Web of Science and quartile ranked (Q1-Q4) published articles involving water quality assessment in Nigeria were analysed. Results indicated shortcomings in various aspects of data analysis and reporting. Consequently, we use simulated heatmaps and graphs to illustrate preferred ways of analysing, reporting, and visualising some regularly used descriptive and inferential statistics of water quality variables. Finally, we highlight alternative approaches to the customarily applied water quality assessment methods in Nigeria and emphasise other areas of deficiency that need attention for improved water quality research.

“…Some anthropogenic activities around the study area with the tendency to impact metallically on the environmental condition and physicochemistry of the creek include: traffic emissions, mechanic workshops, urban and industrial effluents discharge, market, construction and metallurgical works, scrap yard, entrepreneurial firms, sewage disposal, boat manufacturing and maintenance companies, etc. Relatively high level of metallic contaminants such as Pb and Ni metals were reported in investigation patterning to the creek [25]; and that these biologically indestructible heavy metals accumulate in the tissues of living organisms [26].…”

“…Consequently, leading to the ingestion of metals adhered to suspended particles by fishes and other aquatic organisms; hence increasing the risk associated with bioavailability and bioaccumulation [46]. This could account for the high concentration of metals detected in different tissues of grey mullet sampled from Woji creek [26]. Metals bound to particulates in surface water also led to an increased ability for metal transport from the source of metal input to other reaches [47,48,49].…”

The present study is designed to use FactSage version 7.3 to simulate and predict the ionic speciation of lead (Pb) and nickel (Ni) in surface water sampled from Woji creek in Rivers State, Nigeria. Along the 3 km stretch (stations 1 to 5) of Woji creek, in-situ records were taken for temperature, pH and electrode potential (Eh); surface water samples to be assessed for Pb and Ni were collected in sterile bottles. Along the creek, surface water Eh is in the order: station 2 > station 4 > station 5 > station 3 = station 1, with mean value of Eh as 140 ± 20 mV. Surface water pH was close to neutral, and in line with: station 4 > station 2 > station 5 > station 1 > station 3; with 6.81 ± 0.13 as the mean value of pH. The trend of temperature values was recorded as: station 1 > station 2 = station 3 = station 4 > station 5; with the mean value deduced to be 25.6 ± 0.4. Mean concentration of Pb and Ni across the creek were 0.92 ± 0.27 mg/l and 0.46 ± 0.23 mg/l respectively. Pb species exists predominantly in the forms: Pb6(OH)84+(aq) (45%), Pb4(OH)44+(aq) (45%). Other forms of Pb present in the surface water are PbO(s) (5%), PbO2(s) (4%) and Pb2+(aq) (1%). NiO(s) had the highest proportion of Ni in the surface water (67%), followed by Ni(OH)2(s) (30%) and Ni2+(aq) (3%). The predicted metallic species could possibly be sorbet to particulates; thereby increase their chances of bioavailability and subsequent ingestion by fishes and other aquatic organisms. This will in turn influence their bioaccumulation via food chain and increase the tendency of risk impact on man and aquatic ecosystem.
