This study is aimed at determining the physicochemical characteristics of selected wetlands of Kogi State. From each sampled wetlands (Abu’ja and Egwubi), surface water was collected and examined for the following physicochemical parameters: hydrogen ion concentration, electrical conductivity, total dissolved solids and temperature (0C) using Hanna meter. Dissolved oxygen was determined using dissolved oxygen meter. The data collected was analyzed using the Statistical Packages for Social Sciences version 20.0, Paleontological Statistics version 3.14 and Microsoft Office. Physicochemical parameters studied were not normally distributed from test of normality. They were compared using Man-Whitney U and Kruskal-Wallis H nonparametric tests for comparisons between two and more than two groups respectively. In Abu’ja wetland, the temperature for all the months were similar except for January and December which were significantly cooler (p < 0.05); pH was similarly constant except for January and August (p < 0.05). Dissolved solids ranged from 95 to 118 ppm with similar values between months except in March. Mean electrical conductivity ranged from 0.15 to 0.22 ms/cm. These values were similar between months in Abu’ja. Significant fluctuation occurred in dissolved oxygen on monthly basis. In Egwubi study station, temperature ranged from 20oC to 31 oC, significant difference occurred between January and May and between September and November (p < 0.05), pH was also similar between months. Dissolved solids ranged from 26 to 90 ppm. Electrical conductivity ranged from 0.2 to 0.14 ms/cm. Significant differences only occurred between April and August (p < 0.05). Dissolved oxygen was similar throughout the study period. Our result indicated that the essential minerals and other physiochemical parameters are widely distributed but some are not within the normal range of portable water for humans. Both study wetlands showed low pollution, organic waste in Abu'ja site may be handled by autochthonous bacteria and through self purification of the water body. Nutrient levels are high in wetland habitats as wetlands have rich biomes and support high level of biodiversity. The water is suitable for irrigation and livestock consumption.  The presence of the plankton is a pointer to the fact that the two wetlands possess adequate water quality for establishment of great biodiversity.

Water plays a key role in the survival, growth and reproduction of aquatic organisms. Therefore maintaining good quality of water physico-chemical parameters would ensure optimum productivity of aquatic fauna. The study evaluated water physical and chemical parameters (temperature, hydrogen ion concentration (pH), conductivity, dissolved oxygen (DO) and biochemical oxygen demand (BOD) of Bodo Creek. Sample was collected for 5 months (July 2020 – November 2020) at locations previously studied (before-spill baseline studies, 3 years, 5 years, and 7 years after-spill); by using the sampling methods used in previous studies. Spatially, there was no statistically significant difference in temperature (p > 0.05 = 0.997), pH (p > 0.05 = 0.496), DO (p > 0.05= 0.34) and BOD (p > 0.05 = 0.644). However, the difference in conductivity between the stations was statistically significant (p < 0.05 = 0.006). On monthly basis, there was a significant difference in temperature (p < 0.05 = 0.000) and pH (p < 0.05 = 0.005). In contrast, there was no statistically significant difference in conductivity (p > 0.05 = 0.633), DO (p > 0.05 = 0.559) and BOD (p > 0.05 = 0.75). Most of the physico-chemical parameters were not within the WHO recommended levels for the survival of aquatic lives, indicating a high level of environmental pollution in Bodo Creek. This study provides dataset for future evaluation of the water physico-chemistry of Bodo Creek.

Abstract: Five physicochemical parameters (water content, electrical conductivity, total acidity (pH), ash mass fraction and concentration of free acids) were analyzed in 15 sunflower honeys collected from several localities in Vojvodina, Republic of Serbia. The mean values of analyzed honeys were: water content 16.87%; concentration of free acids 27.43 mEq/kg; electrical conductivity 0.34 mS/cm; pH 3.64. The selected physicochemical characteristics of all honey samples from Serbia analyzed in this research can be considered to be within the parameters expected for sunflower honey in general. The values for ash mass fraction, electrical conductivity and concentration of free acids in all sunflower honey samples showed similar trends. High correlation was established between electrical conductivity and ash mass fraction. Statistically significant difference at p≤0.05 (p=0.017) was established only for average values of free acids concentration between honey samples originating from the localities Kanjiža and Čelarevo. All of the analyzed honeys were found to meet national and European legislation for all investigated parameters. Therefore, further research on physicochemical properties of sunflower honey is required to confirm the quality and authenticity of this product and for better understanding the benefits of this honey.

Abundance And Diversity

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.
