“…However, factors 2 and 3 revealed moderate positive loadings for Mn, Zn, Cd, Pb, Ni, SOD, and CAT and moderate positive loadings of Mn, Cu, SOD, AChE, and GST, respectively. This suggests that Mn, Zn, Cd, Pb, and Ni influence an increase in activities of SOD and CAT while Mn and Cu influence an increase in SOD, AChE, and GST activities; Mn, Zn, Cd, Pb, Ni, and Cu could be products of urban and industrial waste from the catchments of Rabigh lagoon [2,38,39].…”

The pursuit of a good candidate to biomonitor environmental pollutants has been on the increase. In this study, the concentrations of Fe, Mn, Cu, Zn, Cd, Cr, Pb and Ni in sediment, seawater and seagrass Cymodocea serrulata compartments and antioxidant enzymes activities in C. serrulata were determined. Our results revealed that bioconcentration factors for all the metals were less than 1 (BCF < 1) and concentrations in seagrass compartments were in the order root > leaf > rhizome for Fe and Mn, leaf > root > rhizome for Cu, Zn, Pb and Ni, and root > rhizome > leaf for Cd and Cr. Effect range low concentrations (ER-L) revealed that Cu, Zn, Cd, Pb and Ni concentrations were above ER-L values and Cr concentration was below ER-L values while concentrations in seawater for all the heavy metals were above the estimate average element concentrations in seawater (ECS). Significant variation (p < 0.05) was recorded for heavy metals in sediment, seawater, seagrass compartments and heavy metal concentrations across stations. Influence of heavy metals on antioxidant enzymes activities; catalase (CAT), superoxide dismutase (SOD), glutathione S-transferase (GST) and acetylcholinesterase (AChE) were recorded, and high activities of the antioxidants were recorded in station S8 corresponding to high concentrations of heavy metals in the same station. There is a need for the promotion of biomonitoring networks across the marine environment using C. serrulata and antioxidant enzymes as biomarkers of oxidative stress caused by environmental pollutants.

“…Our study adds to only a handful of previous studies from West Africa into abundance and diversity of snails e.g., [2,6,16], and is the first from Gombe State Nigeria, to investigate the abundance and diversity of snails in relation to physicochemical parameters. We have shown that the kwadom stream in Gombe state harbors many individual snail species, including the Biomphalaria pfeifferi; the intermediate host of Schistosoma mansoni, and Bulinus forskalii the intermediate host of Schistosoma haematobium.…”

“…Globally, about 5000 species of snails are spread across the world [3], and they are mostly associated with water bodies e.g., lakes, ponds, streams, and dams playing significant roles in medical and veterinary health [2,4,5]. For example, in tropical countries, schistosomiasis and fascioliasis are zoonotic diseases with a complex transmission cycle involving snails as intermediate hosts [5][6][7].…”

“…However, in Nigeria a dearth of studies means very little evidence is available to the public to suggest that the presence of the snails may increase the spread of any of the diseases. Only few studies that we are aware of, e.g., Omudu and Iyough [16] on river Benue, Dogara et al [2] on Warwade Dam in Jigawa State, and Alhassan et al [6] on different water bodies in Zaria, Kaduna state. No study has reported on the abundance and diversity of snails in the Northeastern part of Nigeria, making our study a unique and important one.…”

Aims: The aim of the study is to investigate the abundance and diversity of snails along Kwadom stream, Gombe state, Nigeria. Study Design: Snails were collected using a benthic scoop net with mesh size of 0.2 mm and hand picking from three sampling stations (home, farmlands, and fishponds sites) along Kwadom stream; between 6:30 am to 11:00 am weekly. In addition, physicochemical parameters (temperature, dissolved oxygen, conductivity, alkalinity, water depth and pH) were measured fortnightly to determine their effect on the diversity of snail species. Place and Duration of Study: The study was conducted along Kwadom stream in Yamaltu Deba Local Government Area of Gombe State, Nigeria from March to July 2021. Methodology: Snails were collected from each of the three stations and identified to species level using hand lens and taxonomy keys. Water physicochemical parameters: temperature, dissolved oxygen, conductivity, alkalinity, water depth and pH were measured using standard method. General linear models (GLM) were used to compare the abundance and diversity of the snails across the sampling station, as well as the effect of physicochemical parameters on the diversity of snails. Results: 160 individual snails were recorded from 11 species, including Biomphalaria pfeifferi– the intermediate host of Schistosoma mansoni. The result showed there was a significant difference in the abundance of snails (p<0.01) across the three study sites – home site 68 (42.5%), farmlands site 56 (35%) and fishpond site 36 (22.5%). The home site had a higher diversity of snail species (p<0.01) relative to the farmlands and fishponds sites. Temperature, conductivity, and alkalinity had a significant effect on the diversity of snails. Conclusion: Overall, Kwadom stream harbors many individual snail species, suggesting the need for educating the public on the mode of transmission of diseases that are caused by these snails.

“…This could be linked to different large-scale sources of these trace elements at different sites of the study area, which is a potent way that can be used to check changes in pollution levels (Roca et al 2017). For example, the range value recorded for Cd could be linked to activities in the dyeing industry or urban wastes combustion, while trace elements like Zn and Cu may be influenced by marina activities and the use of Zn in preventing corrosion of alloys and fouling of paints (Chon et al 2010;Zheng et al 2018;Alhassan et al 2020). The significant variation in trace element concentrations in the compartments of seagrass and across the sites can be as a result of uptake and exclusion capacity of these elements by C. serrulata and different anthropogenic activities in the catchments of the sites (Alhassan et al 2020;Aljahdali and Alhassan 2020b).…”

The search for solutions to environmental pollution has been on the increase, with many questions recently as to which marine organisms can bioaccumulate trace elements in the marine ecosystem. Cadmium, Cr, Cu, Fe, Mn, Ni, Pb, and Zn concentrations in sediment, seawater, and seagrass compartments (root, rhizome, and leaf blade) were determined at Rabigh lagoon, Red Sea. This is to provide an insight into the potential of Cymodocea serrulata to bioaccumulate trace elements and as a good candidate to biomonitor these elements in a natural aquatic ecosystem. Results revealed significant variations in trace element concentrations across the three compartments of C. serrulata and the sites, with site S8 located in the most closed part of the lagoon recording the highest concentrations for all the trace elements. The translocation factor (TF rhizome/root = 1.00) of trace elements was higher in the root compartment. This implies that the root compartment is a better bioindicator of trace elements and has more potential to be utilized for biomonitoring. A significant positive correlation (p < 0.01) was established between the trace element concentrations in sediment, seawater, and the three compartments of C. serrulata except for Mn concentration in the compartments. The seagrass C. serrulata can be used for biomonitoring of trace elements in marine ecosystems as our results provide information on its capacity to bioaccumulate these elements. This is one of the key characteristics of a typical bioindicator of aquatic pollutants.
