“…This indicates that the water is critically polluted with respect to heavy metals. Similar results were obtained by [31] in India; and [61] in Nigeria. Fe has the highest concentration in the Mari catchment and Lom River.…”

“…Therefore, in evaluation of HPI, this parameter does not contribute much on HPI value. However, heavy metals like Pb, Cd, As, and Cr have been given no relaxation in drinking water standard and have been given high weightage (Wi) value in HPI calculation by [31]. Hence, even their smaller concentration in water samples makes the water of poor quality and gives high values of HPI [33].…”

To assess the water quality in the locality of Bétaré-Oya affected by an intensive artisanal and semi mechanized mining activities, 71 samples were collected from sixteen points during the 2015-2016 hydrological year. These points include: three in Lom river which is the main stream of the study area, five in Mari river which is one of the left bank tributaries of the Lom, in Bétaré-Oya and eight in the left and the right bank of Mari. Different physicochemical parameters such as pH, electrical conductivity (EC), alkalinity, turbidity, total suspended solids (TSS), cyanide (CN − ), major elements and heavy metals (Pb, Zn, Cd, Fe, Cu, As, Mn and Cr) were analyzed. Water Quality Indices (WQI), Heavy metal Pollution Index (HPI), sodium adsorption ratio (SAR) and percent sodium (Na%) were also computed to evaluate the suitability of water for drinking and irrigation. The results showed that the surface water from Bétaré-Oya was acidic to basic (5.40 < pH < 8.84), weakly mineralized (11.60 < EC < 122.10 μS/cm) with a high concentration of TSS (2 < TSS < 8996.00 mg/L) and turbidity (1.22 to 4758.00 NTU). The WQI scores show excellently to unsuitable quality in almost all the sampling sites. The water quality is found to be most deteriorated in Lom river and in the downstream of Mari river where an extensive mining activity is carried out, with the high WQI value of 5137.40. Based on heavy metal pollution index, the mean value was 1195.36 and thus under the critical pollution index. We thus notice a serious physical degradation by organic and mineral suspended particles as well as chemical degradation by heavy metals. This results from mining activities in the Lom river and its main tributaries such as the Mari river in the upstream part of the Sanaga basin. According to the percentage of sodium and SAR, these waters can be used for irrigation purposes in almost all types of soils.

“…Station 3 has been identified on this creek to be the centre with the highest activities, this is reflected in the high value of HPI. These site-specific high values are similar to those measured in River PovPov in Itakpe Iron-Ore mining area, Kogi State in Nigeria [48] and River Yamuna, Delhi stretch in India [49].…”

Land use is one major factor that affects river water quality which is related to anthropogenic activities. Studies have shown that abandoned boats on watershed, petroleum and untreated wastewater from abattoirs can lead to anthropogenic pollution in surface waters. This study, therefore, was designed to assess spatial and temporal variation of selected heavy metals and level of pollution in Woji Creek. The study was carried out in the months of August, September and October 2018. Water samples were collected from five stations along the creek over a 3.2 km stretch. Water was collected to be analysed for heavy metals (Nickel, Cadmium, Copper, Lead and Iron). Results were subjected to ANOVA and heavy metal pollution index (HPI) was calculated using aquatic toxicity reference values (TRV) as threshold values. Heavy metal dominance in Woji was in the order of Pb>Ni>Fe>Cd>Cu. In the river, Ni had mean values ranging from 0.379±0.259 mg l −1 in August to 0.545±0.369 in October, while Pb with the highest concentration had mean values ranging from 0.229±0.333 mg l −1 in October to 1.534±0.103 mg l −1 in September. Concentrations of metals analysed were high than the TRV. Temporal analysis of HPI calculated for the study was above the critical heavy metal pollution index (100) (August=329.358, September=361.796, October=112.715). A correlation was observed between heavy metals analysed during the study. Spatial analysis of HPI showed higher pollution level at Station 3 with the highest anthropogenic activity along the creek. Cu showed a negative correlation to other metals analysed. Sources of pollution on this creek was identified to be both natural and majorly anthropogenic sources. This study, therefore, points out the need for proper environmental management as regards commercial activities around the waterways.

“…The effluent released from electroplating and distillery industries also constitute a highly rich source of HMs and hence, considered as hazardous to living beings (Venkateswaran et al 2007;Chandra et al 2008). Furthermore, effluent released from domestic activities is also responsible for HM pollution and thus, is of serious eco-toxicological concerns (Bhardwaj et al 2017).…”
