  Pollution by heavy metals deserves a special attention because of their high toxicities and persistence in aquatic environment, especially with respect to such ecosystems that receive chronic inputs of these metals. Physicochemical properties such as pH, Dissolved Oxygen (DO) and Biochemical Oxygen Demand (BOD) that can influence the availability of the metals in aquatic environment were investigated. Water, sediment and floodplain samples were digested by standard laboratory methods. Metal analyses on water, sediment and flood plain samples were carried out by Atomic Absorption Spectrophotometry (AAS). On the whole, the pH of water, sediment and floodplain samples were in the range of neutrality to a little alkalinity (6.52-7.70). The Dissolved Oxygen (DO) for the two seasons were significantly (p>0.05) low in all the study sites. Biochemical Oxygen Demand (BOD) for Rivers Bunsuru and Gagare were also significantly (p>0.05) low when compared with WHO standard of 7.0 mg L-1. Rima River and Goronyo Dam had BOD (p<0.05) on the high side. Except for Rima River, all other rivers had Cu concentrations significantly (p<0.05) high. Lead (Pb) concentrations during the rainy season sampling from River Rima and Goronyo Dam were present above the WHO acceptable limit of 2.0 μg g-1. Other mineral elements and Cd were however within the WHO limits. Significant levels of Pb in water, sediment and floodplain samples mean possible Pb toxicity to aquatic organisms and by implication man through food chain. Presence of Cd even at WHO acceptable limit is at the potential risk of bioaccumulation.

  Wild leafy vegetables are widely eaten in developing countries and serves as nutrient supplements. The present study examined the effect of feeding albino rats with 75% Melocia corchorifolia leaves with respect to their body weight, liver and kidney biochemical, haematological and histological response. Results showed that the rats fed with M. corchorifolia leaves experience decrease in body weight compared to the control group. The Packed Cell Volume (PCV), haemoglobin concentration (Hb) and Red Blood Cells (RBC), White Blood Cells (WBC), platelets, Mean Carpuscular Volume (MCV), Mean Carpuseular Haemoglobin (MCH), Mean Carpuscular Haemoglobin Concentration (MCHC) and leukocyte (lymphocyte, neutophils, monocytes, eosinophils and basophils) differential counts were not significantly (p>0.05) different between control and treatment. Similarly, serum total protein, globulin and bilirubin were not significantly different, but that of albumin was significantly lower (p<0.05) in the treatment than control group. The serum enzyme activities, i.e., aspartate amino transferase (AST), alanine amino transferase (ALT) and alkaline phosphatase (ALP) were significantly (p<0.05) elevated in sample treatment than the control; which is an indication of organ toxicity by cellular destruction induced by the phyto-toxin present in the fed. Renal function indices-serum creatinine, urea, uric acid and electrolytes were not significantly different (p>0.05) between control and treatment. The results of this study showed that Melocia corchorifolia leaves have a relatively low or no toxicity profile.

  Plants are the major sources of microelements to populace of the developing world. However, presence of antinutritional factors limit their optimal utilization. In this paper, antinutritional content and their effect on bioavailability of Ca, Fe and Zn in Melocia corchorifolia leaves was investigated. The result indicated that the plant leaves had high level of tannin (4,689.06±2.60 mg/100 g dry weight, DW). The concentration of other antinutritional factors per/100 g DW is as follows: phytate (88.57 mg), total oxalate (585.00 mg), soluble oxalate (217.50 mg), cyanide (16.02 mg) and nitrate (74.41 mg). The predicted Ca, Fe and Zn bioavailability showed that [Oxalate]/[Ca] and [Oxalate]/[(Ca + Mg)] are below the critical level of 2.5 known to impair calcium bioavailability. Furthermore, [Phytate]/[Ca], [Phytate]/[Fe] and [Phytate]/[Zn] are below the critical level of 0.5, 0.4 and 1.5 respectively. However, [Ca][Phytate]/[Zn], 16.72, is above the critical level of 0.5, which indicates significant effect of phytate on Zn bioavailability. From the results it can be concluded that M. corchorifolia leaves could be an important bioresource for Ca and Fe but not for Zn considering the predicted bioavailability.

  The Pulp of Gardenia aqualla fruit was analyzed for nutritional and anti-nutritional composition. The results obtained were moisture content (80.33%), ash (5.00%), crude lipid (1.70%), crude protein (3.85%), crude fibre (trace), available carbohydrate (89.45%) and the energy value (388.50 kcal/100 g). Elemental analyses shows that Sodium is the most abundant element (203.33 mg/100 g) while manganese is the least (0.2 mg/100 g), Lead was also detected (0.37 mg/100 g). The anti-nutritional parameters analyzed include; Phytate (26.57 mg/100 g), Soluble Oxalate (1.70 mg/100 g), Saponin (1.50 mg/100 g), Nitrate (0.38 mg/100 g) while Hydrocyanic acid content are (1.14 mg/100 g). The antinutrients to nutrients ratio indicate the bioavailability of some important minerals except in the case of [Phytate][Fe] and [Phytate][Ca] in the pulp which are found to reach the critical levels and therefore are expected to hinder Iron and Calcium bioavailability in the pulp.
