The present work determined the concentration and spatial distribution of heavy metals (As, Hg, Cr, Cd and Pb) in soil samples from Makurdi and its environs using geographic information system (GIS). The specific objective is to produce the spatial distribution maps showing the spatial distribution of toxic heavy metals in the study area. Inverse Distance Weighting (IDW), a GIS technique was used to produce dotted maps showing the spatial distribution of heavy metals in neem bark for better visualization of contamination zones and non-contamination zones. The map reveals few hotspot areas showing areas of high concentrations of the heavy metals investigated which were identified in red colours, the following concentration ranges were obtained;As (4.71 - 6.43 mg/kg), Cd (13.9 - 16.84 mg/kg), Cr (46.3 - 60.84 mg/kg), Hg (3.70 - 5.05 mg/kg) and Pb (24.02 - 31.34 mg/kg). These hotspot areas were found close to business outlets, fuel filling and service stations, farm sites where the application of fertilizers and pesticides were persistent coupled with heavy traffic of vehicles and other machinery which was associated with As, Hg, Cd, Pb and Cr been released into the environment thus, suggesting anthropogenic activities controlling the concentration of these heavy metals in the study areas. The cumulative effect of these heavy metals into the barks of neem could pose as danger, because this plant is used as herbs in folk medicine.

Honey bees derive their nutrients from nectars and other plant materials. These naturally available materials are affected by the residual presence of pesticides. The concentration of pesticides in honey comb then reflects the leftover after degradation. In this study, samples of honey were collected from five different farms in Plateau State and analyzed for pesticide residues (atrazine, cypermethrin) and heavy metals (Pb, Cd, Cr, Fe and Mn) using GC-MS and AAS techniques. Results of the analysis indicated that atrazine and cypermethrin were found in the range (0.01 - 0.36 and 0.11 - 0.26) mg/kg, respectively in all the samples. Mn and Fe were found across the samples while Cd was detected only in the sample obtained from Maraban Jos (0.0013 mg/kg). Except Bokkos and Maraban Jos, Pb was detected in other samples. This study revealed that all samples contained the selected pesticide residues above the maximum residue limits recommended by European Union, while concentration of heavy metals in all the samples except Mn was below the maximum concentration limits recommended by Food and Agriculture Organization. The high concentration of pesticide residues in the samples indicates contaminated environment in which the bees fed;therefore intermittent monitoring of the quality of honeys produced would be necessary as this calls for urgent attention.

作者： Peter O. Onuwa Lami A. Nnamonu Ishaq S. Eneji rufus Sha’Ato Department of Chemistry and Centre for Agrochemical Technology University of Agriculture Makurdi Benue State Nigeria

Analysis of six heavy metals (Cr, Mn, Ni, Cu, Zn and Mo) in human scalp hair was carried out among various occupational distributions to ascertain their heavy metal burden, using energy dispersive x-ray fluorescence technique (ED-XRF). The result of the analysis shows that mean concentrations (mg/kg) of heavy metals obtained were as follows: Cr = 17.1 ± 12.7;Mn = 3.11 ± 0.50;Ni = 11.3 ± 9.3;Zn = 451 ± 128;Cu = 83.3 ± 35.8 and Mo is 9.16 ± *** the mean concentrations of Cr, Cu, and Mo were higher in the females, that of Mn, Ni and Zn were more in the males. Statistical analysis of the results for both genders at 0.05 probably shows significant difference for Ni, Zn and Mo while Cr, Mn and Cu showed no significant difference. The relationships between age, body mass, height, and heavy metal concentrations were also investigated. Statistical analysis of the results indicates that there was no correlation between the body mass (R2 ≤ 0.048), height (R2 ≤ 0.002) and heavy metal concentration in hair. Zn showed the highest deviation among other elements in the individual samples for both genders which reflect the individual variation in the concentration of Zn.

A plot of 24 m × 10 m under fallow management after several years of cultivation to maize （Zea mays） was planted to tea （Camellia sinensis） cuttings at 1.0 m ×0.6 m and treated with or without fertilizer. The tea cuttings were applied NPK 25：5：5 （reference fertilizer）, cocoa husk, cow-dung, tea fluff and poultry droppings as manures, mixtures of the manures with urea in 3：1 ratio of N contents as organomineral and the control （no fertilizer）, monitored for growth performance for two years at Kusuku （6°50＇N; 11 °07＇E）, Nigeria. The organic based fertilizers generally outperformed NPK 25：5：5 and control in all the growth parameters. Organominerals resulted in an overall higher plant height, girth, number of leaves and branches compared to the manures in the first year of establishment, while the values were higher for manure treated plants in the second year. This trend was attributed to quicker release of nutrient by the organominerals in the first year, while the manures had undergone adequate decomposition for sufficient nutrient release to the advantage of the tea plants in the second year. However, comparative cost analysis showed that organominerals were more economical to achieve optimum tea production at minimum cost in the locality.

星期五加13历来被认为是非常不吉利的,这是从神话、故事、风俗习惯中一些不好的联想而来的. 据讲,上帝创造了第一个男人--亚当,然后从亚当身上取下一根肋骨用它创造了第一个女人--夏娃.亚当和夏娃被安排看管天堂的伊甸园.上帝让伊甸园里的每种树都生长.其中有一棵美观且果实甜美的树,这是一棵生命之树,一棵能辨别善恶的智慧树.上帝嘱咐他俩'听着,此事非同小可,你们二人可以随便吃任何树上的果子,就是不能吃智慧树上的果子,千万别碰.如果你们吃了这棵树上的果子,就会死去.'

冷季暴雨特别是南方冷季暴雨不但常有发生,其强度和灾害甚至不亚于暖季暴雨。统计表明约有80%的华南冷季强降水与热带卷云羽(简称TP)活动相对应。为此,本文利用近7年FY-2静止气象卫星、TRMM卫星合成降水率数据、ECMWFInterim再分析资料以及地面与探空的常规观测资料等,综合分析了与华南冷季暴雨相关的热带卷云羽的相关特征。分析结果表明,与华南冷季降水有关的TP云产生的源地主要集中在0°~10°N、70°~140°E之间区域内。青藏高原大地形作用对TP引起的华南冷季降水分布具有不可忽视的作用。Hovm6ller图分析显示,TP云在爆发前,云系大多呈连续西传的特征,传播速度约为15~20 m·s^(-1),与大尺度斜压波波速相当或略快。一般来说,与弱降水相比,引起强降水的TP云在爆发前移速较快,受来自对流层中上层的动力强迫影响较大。TP云爆发后,云内强对流区总体移动速度不快,大部分集中在TP云的西南端较小范围内。副热带高空急流只是使得TP云的云盖快速向东扩展。上述特征可能是造成华南冷季强降水中只有个别站点强度大而整体降水强度不强的可能原因。
