    Opis:
    Soil based heavy metals resulting from anthropogenic activities in Kaduna Northern Guinea Savanna of Nigeria was assessed. Soil samples were collected at a depth of 15m with a soil auger using 50m × 50m plots laid in each of the four sites (ST1, ST2, ST3 and ST4) replicated three (3) times to make a total of twelve (12) plots. The assessment was done in two (2) seasons (wet season and dry season). Soil based heavy metals were carried out according to AOAC using atomic absorption spectrophotometer. The data collected were analyzed with descriptive statistic as well as Anova using SPSS package. Eleven (11) soil based heavy metals; V, Cr, Mn, Zn, Co, Ni, Cu, Br, Pb, Cd and Fe were revealed in each of the selected sites. There were significant differences (P<0.05) when concentration are compared between seasons within the sites. Higher soil heavy based metals were recorded in the wet season than the dry season in all the sites. The sites behind Kaduna Refinery and Petrochemical Company (KRPC) is significantly higher (P<0.05) in concentration than all other sites while the control (Kamaku National Park) has the least concentration (P<0.05). Pearson correlation showed a significant and positive association between soil based heavy metals and automobile / farming activities in wet season (R = 0.40**) and dry season (R = 0.95**) as well as in industrial / farming activities in wet season (R = 0.88**) and dry season (R = 0.94**) at 0.01 probability level. It is concluded that variation in the assessment of soil based heavy metals in the selected sites are influenced by anthropogenic activities (mainly agriculture and fossil fuel combustion) in the sites. It is recommended that there should be provision for licensing and registration of all major industrial polluters and monitoring their compliance with laid down standard; further research into anthropogenic air pollution and farming activities which leads to increase in soil based heavy metals especially in the Northern Guinea Savanna where there are limited research should be investigated.

    Opis:
    50m x 50m plots were laid in each of the two (2) sites, replicated three (3) times to make a total of six (6) plots in all. The plants in all the sites were grouped into four (4) growth forms (trees, shrubs, herbs and grasses) which are evaluated using line transect method. The data were analyzed using student ‘t’ test and biodiversity index was calculated using Shannon Weiner method. The result showed that the population density and biodiversity index of the plant composition in the control site are more than that of the flare site from all the growth forms assessed due to combustion of fossil fuel and the heat generated from the flaring site. The mean of the plant species at the flare site is 663.00 and the control site is 1495.00. The standard deviation for the flare site is 4.32 and that of the control site is 2.51. The paired sample ‘t’ test correlation coefficient showed that there is strongly positive correlation efficient of 0.86 between plant diversity at the flare site and those at the control site. However, from the above analysis, it is concluded that there is statistically significant difference between plant species in the flare site and the control site (p<0.05) due to gas flaring that kills and suppress the growth of plants in the flare site. It is recommended that gas should be harnessed for use as liquefied natural gas. Government and NGOs should embark on an aggressive afforestation programme. Government should also enforce law against flaring, major industrial polluters and monitor their compliance with laid down standard.

    Opis:
    The study examines the economic analysis of Hydrocotyle asiata in Kaduna, North Local Government Area of Kaduna State. One hundred (100) questionnaires were randomly administered and forty-one (41) were retrieved from the respondents. Descriptive statistics, farm budgetary techniques and marketing efficiency were used to analyze the data collected. The results show that 60.98% of all sellers were male, while that of female was 39.02%. In addition, 48.78% of the marketers were aged between 31 – 40 years and a majority, 68.29% are married. Furthermore, 43.90% of all these individuals had at least primary education, while 4.88% had no formal education. The traders were also found to be faced with challenges of transportation, seasonality, storage, price fluctuation and pest infestation. The marketing of kola (Hydrocolyte asiata) in the study area is profitable and efficient, with a net income of eleven thousand eight hundred and fifty-one naira, twelve kobo (N11,851.12) per annum and a marketing efficiency of 40.40. However, it is recommended that adequate storage facilities be provided to check excessive dryness of the kola and pest infestation during storage. Moreover, the marketers should form a cooperative group in order to access loan and credit facilities from government so as to boost and improve their market.

    Opis:
    This study was used to assess public opinion of the economic and ecological importance of various tree species in Kaduna Metropolis, Kaduna state. A total of one hundred (100) questionnaires were randomly administered among four purposively selected towns (Angwa-Rimi and Kawo new extension in Kaduna North and Bar’nawa and Sabo in Kaduna South) within the two major local governments in the study area. Twenty-five (25) questionnaires were randomly distributed across age and sex in each of the four (4) selected towns. Of these, ninety were retrieved for analysis. Data analysis was achieved through descriptive analysis. This included frequency distribution tables, percentages and charts. The results show that the majority of the respondents were aged between (21-30) and (31-40) years, these figures representing (44.4%) and (30.0%), respectively, of the entire study population. In addition, most had secondary education (53.3%). In the stated opinions, Meliaceae occur most often. Other trees species identified in the study area include Eucalyptus spp, Azadiracta indica, Psidium guajava, Terminalia catapa, Mangifera indica, Anacardium occidentalis, Khaya senegalensis, Gmelina arboria, pinus spp, Carica papaya, Moringa olifera, Gliricidia sepium, Ficus spp, Afzelia spp, Balanite eagyptiaca, Borassus aethiopum, Persae americana, Polyantha longifolia etc. The following characteristics mark these tree species out as being economically and ecologically important: fast growth, deep rooting pattern, coppicing ability, ability to produce large crown size, tolerance to adverse weather condition, ability of trees to produce broad leaves for shade production, erosion protection, ability to provide fruits, aesthetics and beautification values. In conclusion, urban tree planting is a potential strategy to ameliorate ecological and economic concerns; thus, there is need for the dwellers in the study area to intensify efforts towards planting trees around their houses. Without this, the influx of people, urbanization and industrialization will create deleterious environmental conditions in the study area. It is recommended that efforts to make the populace aware of the economic and ecological significance of urban trees be intensified.

    Opis:
    Concentration of seven (7) metals (Pb, Cu, Zn, Mu, Ni, Cr, and Cd) in the samples of soil and some plant species collected from Kachia military shooting range were determined. The mineral ions were assayed using the acid digestion method and atomic absorption spectrophotometry (AAS). Physicochemical parameters (pH, EC, Bulk density, water holding capacity and Total Nitrogen) of the soil samples were also determined. Of the 7 metals determined in the soils samples, the concentration of Pb (14.85 ± 6.78 mg/kg-1) was the highest compared to the concentrations of other metals. Physicochemical parameters were within the range that allows effective phytoremediation. Cu showed the lowest concentration (0.55 ± 1.68 mg/kg-1). Ni was below the detectable limit in most of the samples. Similarly, concentrations of Pb (12.30 mg/kg-1) in the shoot of Albizia zygia among other metals were higher than those of the other metals in the plant tissues. Concentration of Cd (0.07 mg/kg-1) in the root of Eragotis tremula was the lowest. Generally, metal ion concentration in the soil and plant samples of the shooting range (polluted site) significantly) differed from those of the non-polluted site (P<0.05). Combretum hispidium among the plant species had the highest translocation factor (TF = 2.91). Although the TF was higher in the plant of the polluted site TF >1), reasonable amount of them were retained within the underground tissues (roots).
