The Impact

This study was carried out to determine the impact of gas flaring on microbial and physicochemical characteristics of soil around Ebedei and Kwale Flow Stations in Delta State, Nigeria. Soil samples were collected around Ebedei, in Ukwuani local government area, and Kwale, in Ndokwe West local government area both in Delta State, as well as in their environs. While the soil samples were collected for the analysis of physical, chemical and biological properties of the soil. The highest concentration of the heavy metals was obtained at 10m away from the flaring sites (P < 0.05). In both Ebedei and Kwale, the Fe concentration is significantly higher (1080.33 and 1080.68 mg/kg, respectively) that the other two heavy metals. However, there was a significant difference in the concentration of Zn between Ebedei and Kwale (P < 0.05). In both Ebedei and Kwale, the ECEC concentration is significantly higher (8.16 and 6.57 meq/100g, respectively) that the other chemical parameters. The physicochemical properties were similar at the different distances away from gas flaring sites (P> 0.05). EC decreased from 119.12µs/cm (at 10m) to 50.4 (at 100m) and then to 44.37 (at 200m). pH value remained acidic ranging from 4.97 (at 10m) to 5.9 (at 200m); moisture content ranged from 3.25% (at 10m) to 5.89% (at 200m); organic matter ranged from 1.07% (at 10m) to 1.61 % (at 200m); NO3 reduced sharply from 10.35 mg/kg (at 10m) to 3.92mg/kg (at 100m) and then to 2.4mg/kg (at 200m); phosphate dropped from 0.91mg/kg at (at 10m) to 0.95mg/kg (at 100m) to 0.42mg/kg (at 200m). There was a significant difference in the amount of some physicochemical properties in the soil samples collected from the gas flaring areas in Ebedei and Kwale (P<0.05). Ebedei, Kwale and environs constitute part of the most vegetative and productive areas of the Niger Delta region, these areas are also rich in several pharmacological properties and water resources. The Government should ensure the enforcement of laws aimed at minimizing the amount of gas flared into the atmosphere. Urgent efforts should be geared at cushioning the effect of gas flaring on the communities affected, probably by compensating them or, by relocating them to a more environmental friendly settlement with compensations.

This study evaluated the relationship between selected physicochemical properties and microbial populations of the soil of Bagale Forest Reserve, Girei Local Government Area of Adamawa State, Nigeria. Five plots of 20 x 20 m were laid. Soil samples were collected from five different positions at two soil depths of 0-15 cm and 15-30 cm. The soil samples were isolated in the laboratory for microbial populations and determination of physical and chemical properties. The results obtained revealed that fungal population (7.65 x 105 cfu/ml) was the highest at the soil depth of 0-15 cm, representing 39% of the total microbial populations in the sampled soil of the study area. The results further revealed that the population (6.84 x 105 cfu/ml) of the bacteria had a positive effect on soils of the study area in terms of nitrogen fixation by Rhizobacterial spp. Chemical properties of the soil samples revealed that the available phosphorus exhibited the highest percentage (61.7%) at 0-15 cm soil depth. Analyses of soil physical properties recorded the highest percentage (49.0%) of sand at 0-15 cm soil depth. A similar percentage (50.0%) of sand was exhibited at the depth of 15-30 cm. These percentages accounted for the high porosity (29.0%) of the soil observed at the two soil levels in the study area and could be improved through the application of lime fertilizers. Application of appropriate fertilizers like NPK to improve the soil condition of the study area is highly recommended.

This work assessed the presence of heavy metals in water contaminated with petroleum products in Keffi Local Government Area. Two water sampling station were selected based on the stratified method of sampling of Antau River. Station A is located along Federal Government College Keffi popularly known as Antau Bridge where Agricultural and mechanical activities, with sales of petroleum product take place. Station B was located at Dadin Kowa known as Gada Manu where human activities such as bathing and washing takes place which served as control. The distance between stations is 1km. The procedural plan of this study was monthly sampling of water from both Stations. Materials such as funnel, sampling container, distilled water, conical flask, filter paper, 50ml polypropylene centrifuge tube, cooler were used. Heavy metal concentration was determined using X – ray Fluorescent Spectroscopy (XRF) at the Center for Energy Research and Training (CERT), Ahmadu Bello University Zaria. The water parameters of the four samples were determined using the Extech instrument. The result on Physico – chemical parameters revealed the values obtained from contaminated water samples to be pH (7.31), Dissolved Oxygen (1.14), Electrical Conductivity (8.22), Total Dissolved Solid (4.13), Temperature (27.45) and Salinity (0.091) while the controlled Station at point B were pH (7.43), DO (7.35), EC (3.14), TDS (1.54), Temperature (26.75), Salinity (0.o94) respectively. From the result obtained, the heavy metal contaminated samples had the following values: Mg (29.31±), Al (218.69±), Si (230.12±), S (1153.65±), Cl (54.25±), Ca (106.56±), Ti (23.66±), Cr (3.15±), Fe (15.92±), Cd (7.54±). For the control sample at point B, the following values were obtained: Mg (27.49±), Al (223.71±), Si (243.21±), S (94.84±), Cl (23.52±), Ca (28.44±), Ti (32.99±), Fe (16.63±), Cd (7.67±) respectively. The P-value was 0.8105 (p>0.05) for the water quality parameters while for the concentration of heavy metal P-value was 0.2054 (p>0.05). This implies that there was no significant difference between the concentrations of elements. However, the concentration values of heavy metals in the contaminated water at Station A and control water samples at Station B were higher than the World Health Organization values (Standard) for drinking water

Abstract This study was undertaken to determine the effectiveness of biosurfactants - saponin, tannin and rhamnolipids JBR 515 and 425, for the removal of cadmium, zinc and copper from activated sludge immobilized in 1.5% sodium alginate with 0.5% polyvinyl alcohol. We also established the impact of pH value on biosorbent regeneration with the analyzed biosurfactants and determined the critical micelle concentration (CMC) in solutions containing the biosorbent and biosurfactant and in exact samples with heavy metals. Saponin exhibited the highest effectiveness of metals leaching at pH 1-5, and rhamnosides at pH 5-6. In addition, the study demonstrated a significant effect of the ratio of biosorbent mass to washing agent volume (m/V) on the effectiveness of metals leaching. Of the biosurfactants analyzed, saponin was ca. 100% effective in leaching zinc and copper. The effectiveness of the other biosurfactants was lower and depended on the metal being leached

Talinum Triangulare

Introduction: Talinum triangulare is a nutritious vegetable whose consumption is popular in Nigeria. Therefore, the necessity to consume a very quality and hygienic T. triangulare cannot be over emphasized. Aims: To investigate the nutrient contents and level of heavy metals in T. triangulare collected from dumpsite and farmland. Place and Duration of Study: Department of Botany, Lagos State University, (Oko fili in Alimosho Local Government Area) and farmland (Post Service in Ojo Local Government Area) between January to March, 2021. Methodology: The data were analyzed using statistical package for social sciences (SPSS) version 20 and a standard procedure was used for t-test analysis. Results: All the amino acids detected in T. triangulare from both dumpsite and farmland had no significant differences (p>0.05). There are no significant difference (p>0.05) between lead (Pb), cobalt (Co), copper (Cu), chromium (Cr) and selenium (Se) in samples examined across the two sampling sites, while arsenic (except in the soil from dumpsite) and nickel (except in plant from both sites) were not detected. However, the concentrations of heavy metals such as calcium(Ca), iron(Fe), potassium(K), magnesium(Mg), sodium(Na), phosphorus(P), and zinc (Zn) in both the soil and T. triangulare  samples from the dumpsite are significantly(p<0.05) higher than that from the farmland. The respective values of these metals (mg/100g) in the plant at dumpsite and farmland are: Ca (343.400±206.475), Fe (82.000±29.839), K(90.900±10.748), Mg(1595.250±149.553), Na(2217.050), P(502.250±140.077) and Zn(60.620±8.739) respectively. Conclusion: Therefore, T. triangulare examined in this study is safe for consumption, however its excess K, Na, and Mg content can be recommended for people with deficiency in those nutrients.

ABSTRACTSoil transmitted helminthes (STHs) are common public health concern among children in Sub saharan Africa. A study to determine the prevalence and intensity of these parasites among pupils of two primary schools in Nkpor and Mgbodohia communities, Obio/Akpor Local Government Area, Rivers State, Nigeria was conducted. The formo-ether concentration technique was used to concentrate and separate the eggs and cysts from the faeces. Out of 107 pupils (56males and 51 females) investigated, 81 (75.7 %) were positive for at least one gastrointestinal helminth. The parasites identified included Ascaris lumbricoide(58.0%), Hookworms(28.4%), Trichirus trichiura(13.6%) and A.lumbricoide + T. trichiura (6.3%). Ascaris lumbricoide was significantly (P<0.05) higher in prevalence than other parasites. Although more females (54.3%) were infected than males (45.7%), there was no significance(P>0.05) difference in the prevalence in relation to sex. Of the 44 males infected, 24(54.5%), 5 (11.4%), 13(29.5%) and 2(4.5%) haboured A. lumbricoide, T. trichiura, Hookworms and mixed infection (A. lumbricoide + T. trichiura) repectively. Out of the 37 females infected, 21 (56.8%), 3(8.1%), 10(27.0%) and 3(8.1%) haboured A. lumbricoide, T. trichiura, Hookworms and mixed infection (A. lumbricoide + T. trichiura) repectively. There was no significance difference in the prevalence of A. lumbricoide and Hookworms between males (54.5%) and females (56.8%). There was significant difference in prevalence among two major age groups (5-10years-45% and 11-15years-41.9%). Children within the age group of 16-20years had the least infection (9.9%). The intensities of A.lumbricoide, T.trichiura and hookworm were 246.5, 107.5 and 187 Epg respectively. The intensity of A. lumbricoide was significantly difference than other parasites identified.Soil transmited helminthes remain a public health concern among children in the study area. Provision of portable water, toilet facilities, good education on the epidemiology of STHs and regular de-worming will enhance control measures.

The negative impact of gas flaring on the environment cannot be overemphasised. This study assessed the effect of gas flaring on the physicochemical properties and heavy metal contents in soils of Ebocha gas flaring site in Rivers State. It involved the assessment of various distances from gas flaring point to 200 meters away (50 m, 100 m, 150 m, and 200 m) which represents the extent of gas flared pollution on soils to determine the physicochemical properties and heavy metal load. The gas flaring significantly decreased soil organic carbon and calcium content when compared with non-gas flaring polluted soils. Soil acidity increased, soil exchangeable ions decreased. N, P and K were altered in gas flared soils when compared to the controls. There were detrimental effects on soils physicochemical properties. Heavy metals observed were Cd (Cadmium), Ni (Nickel), As (Arsenic), Cr (Chromium), while Pb (Lead) was not detected. The concentration of heavy metals in gas flared soils decreases down soil depth from 0-15 cm to 45-60 cm respectively. The gas flaring extremely caused the acidic nature of gas flared soils. Coefficient of variation (CV) in percentage shows significant increase in acidic nature of the gas flared soils when compared with the control soils.
