Levels of some heavy metals in vegetables from artisanal mining sites of Dilimi River, Bukuru and Barkin Ladi North Central Nigeria: any public health concern?

North Central Nigeria is the food basket of Nigeria but is also known for its artisanal mining with attendant public health consequences which is hitherto unquantified. Vegetables grown close to these mining sites may be contaminated with heavy metals. This study has estimated health risk associated with heavy metals HM (Cd, Cr, Cu, Zn, Se and Ni) in vegetables harvested inform the mining areas of Dilimi, Bukuru and Barkin Ladi by calculating the Daily intake, Target Hazard Quotient (THQ), Hazard Index (HI) and the Cancer risk (CR) for adults and children in the local population. Vegetable, soil, irrigation water and sediments samples were collected, digested, ashed and analyzed for HM using an Atomic Absorption Spectrometer (AAS). The concentration of heavy metals in vegetables were in the order Cd < Se < Cr < Cu < Ni < Zn. There were higher HM levels in soil than vegetables samples. The daily intake of HM from vegetable consumption decreased in the following order Cd < Se < Cr < Cu < Ni < Zn. At least 62.5% of vegetable samples had THQ values > 1 in Dilimi, Bukuru and Barkin ladi (Adults) while 13% of vegetable samples had THQ values > 1 in children. The THQ of nickel ranged from 0.38-2.73 and 0.21-1.53 in adults and children respectively. The bio-concentration factor ranged from 0.026-7.52, 0.01-0.36 and 0.0011-1.23 in Dilimi, Bukuru and Barkin Ladi respectively for all the studied heavy metals. The cancer risk values ranged from 0.011-0.04 and 0.00066-0.02 across all the studied areas for adults and children respectively. HI values for adults were all >1 and also the total cancer risk was above the acceptable range of 10-4. Since THQ is > 1 in most of the samples, HI values > 1 for adults in all the vegetable and cancer risk above the acceptable limit consumption of vegetables from the study areas is not free of risk.

Prevalence of Human Malaria Infection and its Transmission Pattern in the Highlands and Lowlands of Plateau State, Nigeria

Objectives: To quantify the prevalence of Plasmodium species and transmission patterns of human malaria in the highland and lowland areas of Plateau State, Nigeria. Methods/Statistical Analysis: Malaria prevalence studies were conducted from November, 2015 through to October, 2016. Microscopic examination using thin and thick blood smears was employed. Determination of malaria parasite presence and Plasmodium species identification was carried out using X100 objectives under oil immersion. Chi square (χ2) statistics was used to test statistical significance of the relationship between sex, age and occupation. Findings: The results show the overall prevalence of malaria infection in the study area was 48.1%. The most prevalent malaria parasite recorded in this study was Plasmodium falciparum (94.1%). This was followed by Plasmodium malariae (5.9%). Sex related prevalence by LGA show that infection did not differ significantly in all the LGAs (P> 0.05) except in Barkin Ladi LGA where males had significantly higher infection than females (P 0.05). Transmission occurred all year round. In the highlands, transmission peaked in June whereas in the lowlands, it peaked in July. The variation in transmission patterns observed in this study will be informative in planning programmes geared towards controlling the disease. Application/Improvements: This study has provided a better understanding of the epidemiology of malaria in Plateau state which will help in formulating specific and efficient intervention strategies.

Lead Levels in Vegetables from Artisanal Mining Sites of Dilimi River, Bukuru and Barkin Ladi North Central Nigeria: Cancer and Non-Cancer Risk Assessment

Lead (Pb) contamination of foods and especially of frequently consumed vegetables is a growing public health concern worldwide. Although levels of exposure in developed countries have declined over the past decades, the same cannot be said of developing countries. Health risk assessment has increasingly been employed to determine the potential hazard of heavy metal exposure to humans. In this study vegetable samples (tomatoes, red pepper, brown beans, lettuce, cabbage, Irish potatoes, onions, green beans and carrot), soil samples, irrigation water and sediment samples were collected from the Dilimi River, Bukuru and Barkin Ladi communities in north central Nigeria and analyzed for Pb content using atomic absorption spectroscopy. The results showed levels with ranges from 0.5 – 2.4 mg/kg (Dilimi River), 0.3 – 1.7 mg/kg (Barkin Ladi) and 1.46 – 1.89 mg/kg (Bukuru) in vegetables were largely above the maximum permissible limit recommended by WHO/FAO. The lead levels found in soil samples, which ranged from 9.19 – 36.042 mg/kg, also exceeded some safety standards. At least 75% of the calculated estimated daily intakes of Pb from different vegetable samples were also higher than the permissible tolerable daily intakes PTDI (0.0035 mg/kg day-1) of Pb in both adults and children. Target hazard quotient THQ values > 1 were also observed in children. In conclusion, there is a health risk from consumption of vegetables in these mining communities.

Characterization and photocatalytic activity of Barkin-Ladi ilmenite ore under visible light irradiation

Photocatalysis is an advanced oxidation process that can be carried out at room temperature under atmospheric pressure using atmospheric oxygen as the oxidant and the sun as the source of energy. This work focuses on the composition and photocatalytic activity of the raw and calcined samples of ilmenite ore obtained from Barkin-Ladi, Plateau State, Nigeria, using methyl orange as the model substrate under visible light irradiation. The ilmenite ore was characterized using X-ray fluorescence (XRF) spectroscopy and X-ray diffractometry (XRD). Barkin ladi ilmenite ore is basically composed of the rutile phase of TiO2 and ilmenite (FeTiO3) and small amount of gangue minerals. Upon calcination at 800 °C, FeTiO3 of the ore converted into a mixture of Fe2O3 and TiO2. The photocatalytic activity of the ilmenite ore did not change much after calcination at 500 - 700 °C. The ilmenite ore calcined at 800 °C exhibited the lowest photocatalytic activity. Significant improvement of the photocatalytic degradation of methyl orange was observed upon addition of H2O2 into the system.Key words: Photocatalyst, Ilmenite ore, Calcination, Methyl orange, Degradation

Seroprevalence of foot and mouth disease (FMD) among sedentary cattle in northern Plateau, Nigeria

This study was aimed to determine the seroprevalence of foot and mouth disease (FMD) in cattle and identifying the potential risk factors associated with the disease among sedentary cattle in northern part of Plateau state, Nigeria. Two hundred and seventy cattle aged from 6 months to ?3 years old were randomly selected and identified and whole blood collected from the jugular vein using plain evacuated tubes. Whole blood was processed and separated and sera were screened for foot and mouth disease virus (FMDV) 3D non-structural proteins using blocking enzyme linked immunosorbent assay (ELISA). Overall, 55.9% (95%CI: 49.96-61.77) FMD seroprevalence was obtained from the study area. Seroprevalence was highest in Riyom (82.5%), followed by Barkin Ladi (66.2%), Jos South (55.5%) and Bassa (41.2%) (x2 = 17.21, P&lt;0.05). Risk factors for age, management system and location were significant associated (P&lt;0.05) with seroprevalence of FMD. However, there was no significant association with sex (P&gt;0.05). The prevalence odd ratio of FMD was more in Riyom than in Jos South, Barkin Ladi and Bassa (P&lt;0.05). Prevalence odd ratio of FMD was more in extensively managed system relative to intensively managed system, more in adult cattle aged &gt;2 years old. This study has indicated that FMD is an important disease among sedentary cattle in Northern Plateau, however little is currently known about the economic impact of the disease on the local farmers and their livelihoods. As a control measure, efforts should be improved on animal movement during outbreaks while prophylactic control using vaccination should be considered as another option using vaccines containing virus representative of the region.Asian J.

Seroprevalence of bovine brucellosis in northern Plateau State, North Central Nigeria

ObjectiveTo determine the seroprevalence of brucellosis among cattle in some local government areas (LGA) of the northern part of Plateau State, Nigeria. MethodsSera obtained from a total of 270 randomly selected cattle from different herds in the four selected LGAs were for Brucellaantibodies using the Rose Bengal Plate Test (RBPT). ResultsAn overall brucellosis seroprevalence of 9.6% (26/270) was obtained. The seroprevalence of Brucella antibodies among the cattle across the LGA ranged from 0%-37.3% with Riyom and Bassa LGA having the lowest and highest seroprevalence respectively while Barkin Ladi LGA had no sero-positive cattle. Females had a higher percentage of seropositives compared to males while cattle reared under extensive system of management had a higher (11.6%) percentage of sero-positives compared to cattle kept under the intensive system of management. However, there was no statistically significant (P>0.05) association between serological status and sex or management practice. ConclusionsThe results of this study indicates that bovine brucellosis is still a problem among the cattle population in Plateau State, Nigeria. And the public and other animals are at risk of exposure to the disease agent in these animals which are still shedding the organism.

Parasitological Evaluation of Domestic Water Sources in a Rural Community in Nigeria

Aim: To evaluate the level of safety of water sources in a rural settlement in Nigeria with reference to parasitic infections and to make appropriate recommendations to the government and the community dwellers. Study Design: Investigative study. Place and Duration of Study: Samples were collected in Heipang, Barkin Ladi Local Research Article British Microbiology Research Journal, 3(3): 393-399, 2013 394 Government Area of Plateau State, Nigeria between October-December, 2012. They were processed at the General Laboratory of National Veterinary Research Institute, Vom, Nigeria. Methodology: 100 water samples were collected from domestic water sources. 10 of the samples were from streams, 60 from ponds, 20 from wells and 10 were from bore holes. Samples were investigated for presence of parasites using standard World Health Organisation approved laboratory techniques. Each sample was subjected to macroscopy, filtration, centrifugation and microscopy. Results: It revealed that 59 out of 100 water sources investigated had parasitic infestation. Ponds had the highest degree of parasitic contamination (78.3%), streams followed closely with 50%, while wells and bore holes had 35% and 0% in that order. Helminths were the leading parasitic genera encountered with Ascaris species accounting for 33.9% of the parasites. Hookworm was the second most common helminth with the prevalence of 20.3%. Strongyloides species accounted for a paltry prevalence of 3.4%. Protozoan cysts of Balanditium coli and Entamoeba histolytica accounted for 18.6% of parasites each. Conclusion: These findings clearly show that most water sources in the study area constitute grave epidemiological threat to public health. Inhabitants of such communities should boil or treat their water before consumption while government authorities should provide safe drinking water to the rural dwellers.

Comparative Study of Some Heavy and Trace Metals in Selected Vegetables from four Local Government Areas of Plateau State, Nigeria

This study was conducted to analyze some heavy and trace metal contents of selected edible vegetables commonly sold in four local government areas (LGAs) of Plateau State, Nigeria, with a view to unearth their toxicological implications on the populace. The vegetables sampled are Spinacia oleracea (spinach), Lactuca sati (lettuce), Cucumis sativus (cucumber), Daucus car (carrot) and Brassica oleracea (cabbage), while the metals analysed are Cd, Pb, Fe, Cr and Mn. Atomic absorption spectrophotometer was used to determine the concentration of the various metals and Tukey-Kramer multiple comparison tests in a one-way analysis of variance was used to compare variations in metal concentrations. Cd and Pb were not detected in all the vegetables sampled from Bassa LGA, but were detected in vegetables of Jos-North, Jos-South and Barkin Ladi LGAs. Cd and Pb concentrations in most samples from Jos-North, Jos-South and Barkin Ladi LGAs were above the WHO maximum permissible limits for vegetables. Cr concentrations in all the vegetables from all the LGAs were far above the WHO maximum permissible limit in the order: Jos-South > Jos-North > Barkin Ladi > Bassa. Fe concentration in most vegetables from all the LGAs is above the WHO maximum permissible limit in the orders: Jos-North - Lettuce > Spinach > cucumber > carrot > cabbage; Jos-South - Lettuce > Spinach > cabbage > carrot > cucumber; Barkin Ladi - Lettuce > cucumber > Spinach > carrot > cabbage; Bassa - Letuce > carrot > spinach > cabbage > cucumber. Mn order of concentrations in the vegetables is: Jos-north - spinach > Lettuce > carrot > cucumber > cabbage; Jos-South - spinach > lettuce > cabbage > carrot > cucumber; Barkin Ladi - Lettuce > cucumber > Spinach > carrot > cabbage; Bassa - Lettuce > spinach > cabbage > carrot > cucumber. The order of lead concentrations in the vegetables are: Jos- North - cabbage > spinach > carrot > lettuce > cucumber; Jos-South - Lettuce > cucumber > carrot > cabbage > spinach; Barkin Ladi - Lettuce > spinach > cucumber > carrot > cabbage. The results indicate that vegetables from Jos-North, Jos-South and Barkin Ladi are contaminated with the metals sampled, while lettuce and spinach are very good bioaccumulators of these metals.

Participatory rural appraisal of livestock diseases among the Fulani community of the Barkin Ladi Local Government Area, Plateau State, Nigeria.

The effect of long-acting oxytetracycline treatment in the development of sequestra in contagious bovine pleuropneumonia (CBPP)-infected animals was determined. Thirty five clinically healthy zebu cattle, negative for CBPP antibodies (as tested by a competitive ELISA), were infected with Mycoplasma mycoides subsp. mycoidessmall colony variant - field isolate. All the animals were monitored for clinical signs of illness and regularly sampled for serological and bacteriological analysis. Nine animals were treated with long-acting tetracycline upon the first evidence of clinical signs of illness. The 26 remaining animals were left untreated and served as control animals. Post-mortem examinations were performed to assess the presence or absence of CBPP gross lesions. The experimentation lasted for 10 months during which, 13 animals (all untreated) died with acute lung lesions. When the 22 surviving animals (13 untreated and 9 treated) were slaughtered at the end of experimentation, chronic lesions were observed in all of them. Among the 13 untreated animals, 10 had visible lung sequestra and 3 had cicatrical lesions indicative of resolved lung lesions. Conversely, among the 9 treated animals, only 1 had a small lung sequestrum and the remaining 8 had pulmonary adhesions. The results presented demonstrate that, under the experimental conditions used, treatment with oxytetracycline did not result in significant sequestra formation in CBPP-infected animals. Full field validation is required in order to confirm these findings. Key words: Participatory rural appraisal, open-ended interview, proportional piling, key informants, animal disease control.

Impact of technological change on output of potato production in Plateau State, Nigeria.

This study assessed the impact of technological change on output, of potato in Plateau State, Nigeria. It was carried out in four Local Government Areas Jos south, Bokkos, Mangu and Barkin Ladi were purposively randomly selected from eight noted for potato production. The sample size was 240 households but only 182 were used in the analysis of the data. The primary data were collected using structured questionnaire and data were collected forthnightly. Two improved potato varieties (Nicola and Lady Christy) and one local variety (Empi) were used in this study. The production systems were Furrow/Flood Irrigation and Manual watering. Cobb-Douglas production functions were estimated for the potato varieties and production systems. Chow's test's were carried out to test for structural shifts in production functions, for production system and varietal effects, homogeneity of slopes and differences in intercepts. The results showed that under Furrow/Flood Irrigation Production System, R was 0.48 for Lady Christy, 0.60 for Empi, 0.29 for Lady Christy and 0.21 for Nicola. The coefficients of the variety dummy variable were positive and statistically significant at 5% level, indicating that Nicola and Lady Christy gave higher yields than Empi (Local variety). The coefficients of the production systems dummy variables were not significant even at 10% level, so there was no difference between the yields of the improved varieties and the local variety in the two production systems. Covariance analysis for the three potato varieties grown in the two potato production systems were statistically significant at 10% level. The introduction of Nicola and Lady Christy caused a shift upwards of the Empi (Local variety) production function. There was homogeneity in the slopes of the production functions and so confirmed that the potato production functions were factor neutral. There was a decreasing returns to scale for almost of the production functions.Keywords: Technological change, output of potato, Production function.

Economic Mineral Potentials Of Tailing Dumps From Alluvial Mining In Parts Of Jos Plateau, Northcentral Nigeria

Several tonnes of mine tailing dumps abound in the alluvial tin mining areas of the Jos Plateau. These tailings are considered low in contents of cassiterite, columbite, tantalite, zircon and other minerals normally won from tin mining. Four of these dumps in four different mines located in Barkin Ladi (BL), Gurum (GM), Sabon Gida Dan Yaya (SGDY) and Sabon Gida Kanar (SGK) have been studied to assess their economic potentials. Samples were collected and analysed using AAS for tin, niobium, tantalum and iron; colorimetry for titanium and gravimetry for zirconium. The results of the initial geochemical analyses showed the contents of tin ( Keywords :Jos Plateau, Alluvial, Tin mines, Tailings, Recovery.

Effect Of Technological Change On Output And Factor Shares In Potato Production In Jos Plateau Area Of Plateau State, Nigeria

This study was carried out in four Local Government Areas in Plateau State – Jos South, Bokkos, Mangu and Barkin Ladi, which were randomly selected from eight noted for potato production. The sample size was 182 used in the analysis of the data. The primary data were collected using structured questionnaires forthnightly. Two improved potato varieties (Nicola and Lady Christy) and one local variety (Empi) were used in this study. The production systems were Furrow/Flood Irrigation and Manual watering.The factor shares in the cost of production were estimated and the technical change biases measured. The factor shares were estimated using a normalized Cobb- Douglas profit function to indirectly estimate the partial elasticities of the Cobb-Douglas production function with constant returns to scale. Capital had the highest cost-share of 57.2% under the Manual watering production system, while labour had the least ( 12.5%). The technological change biases introduced by different potato varieties under the different production systems were factor-saving for labour and fertilizer but factor-using for land and capital in Nicola under Furrow/Flood irrigation production system. Normalized Cobb-Douglas profit function indirectly estimated the partial elasticities of the Cobb-Douglas production functions with constant returns to scale for potato in Jos Plateau.

Efficacy of single-dose amodiaquine co-administered with sulfadoxine/pyrimethamine against falciparum infection in Barkin Ladi, an area of multi-drug resistant malaria

A study was conducted in Barkin Ladi on the North Central plateau of Nigeria to assess the efficacy and tolerability of a single-dose (10 mg/kg) amodiaquine co-administered with sulfadoxine/pyrimethamine (SP) against Plasmodium falciparum malaria in children less than 5 years of age using a 14-day protocol. The combination was highly efficacious in 41 patients involved in the trial, producing rapid parasite clearance (MPCR= 2.73 days) and faster clearance of fever (MFCR= 1.2 days). Adequate clinical and parasitological response (ACPR) achieved was 97.6%, while there was 1 (2.4%) case of late parasitological failure (LPF). The single-dose combination produced a significant improvement in PCV (p

Declining efficacies of chloroquine and sulfadoxine-pyrimethamine combination against &lt;i&gt;Plasmodium falciparum&lt;/i&gt; on the North Central Plateau, Nigeria: parasitological performance of the drugs

The sensitivity of Plasmodium falciparum to chloroquine (CQ) and sulfadoxine-pyrimethamine (SP) combination was assessed in vivo in children under five years of age in Barkin Ladi, in the cool Plateau of North Central Nigeria using the standard 14-day protocol. This was the first study of its kind, in this part of the country, under the new roll-back-malaria (RBM) initiative of the World Health Organization (WHO) Plasmodium infection was detected in 42% of the children screened: pure P. falciparum, 97% pure P. malariae, 2 mixed P. falciparum and P. malariae, 1%. The computed parasite density index (PDI) was 7.42. Children who qualified for enrolment into the study (54 for CQ and 55 for SP) were on average 31.1+14.7 and 26.5 + 14.9 months old, weighing 12.1+2.9 and 10.8+3.6 kg, respectively. Average drug consumptions were 304.0+72.3 mg for CQ and 0.6+0.2 tablet for SP. Cure rates were only 43% and 85%, while mean parasite clearance times (MPCTs) were 5.07 and 3.37 days, respectively confirming a significant decline in sensitivity of P.falciparum to the drugs. The need for an effective first-line drug as well as for combining SP with an effective anti-malaria drug is strongly emphasized. Nigerian Journal of Parasitology Vol. 25, 2004: 57-63

Comparative assessment of the clinical performance of chloroquine and sulphadoxine/pyrimethamine in the treatment of &lt;i&gt;Plasmodium falciparum&lt;/i&gt; infection in Plateau State: an open randomised study of 109 children with acute uncomplicated malaria

Background : Malaria remains one of the most common threats to child survival in Nigeria. Chloroquine (CQ) is the first line drug of choice against uncomplicated malaria. In view of reports indicating an increasing resistance of P. falciparum to CQ, a regular surveillance of malaria therapy requires constant evaluation of its efficacy and that of suitable alternatives. Objective : To compare the current efficacy of CQ with that of sulphadoxine/pyrimethamine (SP) in the treatment of P falciparum infection in Plateau State. Patients and Methods : Using a 14-day protocol, an open randomized study of the efficacy of CQ and SP in the treatment of uncomplicated P. falciparum infection was conducted in 109 febrile children under five years of age in the Barkin Ladi Local Government Area of Plateau State. Adequate clinical response (ACR), adequate clinical and parasitological response (ACPR) and clinical efficacy (CE) were assessed in the two treatment groups. Results : Out of the 708 children screened for P. falciparum parasitaemia, 378 (53.4 percent) tested positive. One hundred and nine of the 115 children who qualified for enrollment, completed the study. Fifty-four and 55 children received CQ and SP, respectively. The mean (SD) duration of illness before presentation at the hospital was 1.5 (0.71) days. The means of age, temperature, packed cell volume and parasite counts on admission to the study were similar in the two treatment groups. Thirty-nine (75 percent) of the 52 children who received CQ, and in respect of whom the data was complete, attained clinical cure compared to 52 (94.5 percent) of 55 children on SP (p= 0.013). Twenty-seven (51.9 percent) of 52 children treated with CQ versus 48 (87.3 percent) of 55 children on SP achieved adequate clinical and parasitological cure (p=0.00010). Thirty (57.7 percent) of 52 children on CQ versus 48 (87.3 percent) of 55 children who received SP were clinically cured (p = 0.0012). Failure to achieve fever clearance by day 14 was noted in eight (16.7 percent) of 48 children on CQ against four (7.3 percent) of 55 children on SP. Conclusion : Although both drugs fell short of a hundred percent cure rate, CQ performed less creditably than SP in the treatment of uncomplicated malaria. There appears to be an urgent need to seek other effective alternative first-line anti-malarial drugs in the country. Nigerian Journal of Paediatrics Vol. 31(3) 2004: 87-92

Farmers’ Assessment of the Training and Visit Extension System in Central Nigeria: Evidence from Barkin Ladi, Plateau State

The Training and Visit (T&V) extension has been criticized for being top-down, top-heavy, inefficient and ineffective. The purpose of this study therefore was to assess the effectiveness of the T & V extension in Barkin-Ladi Local Government Council (LGC), Plateau State in Central Nigeria. Four specific objectives guided the study. A total of 60,000 farmers who had been in active production between 1986 and 1995 in the LGC constituted the population for the study. A three percent sample (1,800) was randomly selected for the study. A structured questionnaire was used to collect data pertinent to the study. Data were descriptively analysed. Demographically, majority of the respondents were males, aged 25-26 years, and married. Slightly less than 50 percent (43.5%) were literate. Majority had farmed for at least 11 years (53%) and had land holdings almost exclusively by inheritance (96%). Other results of the study indicated that although majority of the respondents had contact with extension agents, most depended on other sources for agricultural information. Respondents reported that the frequency of extension visits were unsatisfactory, but found the information given by extension agents very useful. Majority of the respondents were aware of recommended agricultural technologies. The adoption of fertilizer and improved crop varieties was higher than capital-intensive innovations such as mechanized land preparation and use of fishing gear. Recommendations were made on the basis of major results of the study.

Bovine trypanosomosis in sedentary cattle at previously assumed trypanosoma-free Jos plateau, Nigeria

The occurrence of trypanosomosis was investigated in sedentary Bunaji (Bos indicus) cattle grazing at 5 different villages of Barkin Ladi Local Government Area of Plateau State, Nigeria. Two hundred cattle was examined, 76 (38.0%) of which had trypanosome infection. Three species, Trypanosoma vivax (78.9%), T. Congolense (15.8%), and T. brucei (5.3%) were encountered. More males (42.9%) than females (31.8%) were affected while animals of 3-5 years age cohort had the highest infection rate of 46.7%. The existence of trypanosome infections in sedentary cattle populations of the Jos Plateau seem to suggest that the area which was previously assumed to be Trypanosoma-free may have acquired infection status.
