“…The bioconcentration factor (BCF) reflects the transfer of a heavy metal from the liver tissue to liver flukes, and was obtained by dividing the concentration of a heavy metal measured in the parasite's tissue with the concentration of the same 13 . All the heavy metals identified in this study had BCF values greater than 1.0 (Table 3).…”

Exposure of living organisms to heavy metals can lead to bioaccumulation and can have some detrimental health effects. This study identified the species of liver flukes present in the liver tissues of water buffaloes, determined the concentration and bioconcentration factor of cadmium, copper, lead, and zinc present in both the liver tissues and liver flukes using atomic absorption spectrophotometry. Of the 1,329 liver flukes extracted from the 14 livers, Fasciola gigantica (F. gigantica) was the only species present in the collected liver tissues. The median heavy metal concentrations (µg/g) in the liver tissues were 0.93, 9.13, 4.75, and 48.95 for cadmium, copper, lead, and zinc, respectively. F. gigantica had median heavy metal concentrations (µg/g) of 3. 32, 72.26, 20.82, and 159.37 for cadmium, copper, lead, and zinc, respectively. Both the liver tissues and F. gigantica were identified to contain varying concentrations of these heavy metals (p<0.05). The presence of these heavy metals in both the liver tissues and F. gigantica suggests heavy metal contamination of the areas where the carabaos graze. The bioconcentration factors for cadmium, copper, lead, and zinc were greater than 1.0 indicating that liver flukes are good bioaccumulators and bioindicators of environmental pollution.

“…The values of the parameters such as chloride, sulphate, alkalinity and hardness (total) were high in both groundwater and treated wastewater samples (Table 1). Generally it is assumed that crops irrigated with wastewater show metal toxicity which might pose potential health risks to the consumers (Khan et al, 2008;Shad et al, 2013;Satpathy et al, 2014). Since, the wastewater does not contain high level of heavy metals, therefore no significant transfer of metals to soil and hence to crop plants was reported ( Table 2).…”

In the present investigation, tomato plants irrigated with treated wastewater were evaluated for their toxicity using short term (acute) animal studies. Male wistar rats fed with tomato plants at the dosage of 150 and 300 mg kgG 1 b.wt. for 14 consecutive days showed no symptoms of toxicity. Assessment of haematological parameters such as RBC, WBC, haemoglobin, platelet count showed no significant changes. Plasma and serum analysis also indicated no significant differences in parameters such as urea, AST, ALT, ALP, bilirubin in all the treatments. The present investigations suggested that short term wastewater irrigation in plants do not pose any toxicity to animals. The toxicity depends upon the level of composition of treated wastewater and its transfer to the soil and then plants. Further studies are required to assess toxic effect of long term irrigation with treated wastewater.

“…This is one of the first steps in which heavy metals enter our biosphere and thus, the human food chains [6]. Heavy metals become toxic to the plants when it exceeds maximum acceptable limits [7]. Toxic heavy metals could be absorbed and then accumulated by plants which might eventually enter the human body through the normal food intake.…”

Aim: This study was undertaken to assess the heavy metals contamination level in rice grains (Oryza sativa) from Nasarawa West, Nigeria. Study Design: To estimate the contamination factor, degree of Contamination and Pollution load index of rice samples from Nasarawa west using the world health organization/food and agricultural organization acceptable limits of some toxic Heavy Metals in Food as reference heavy metals concentration. Place and Duration of Study: The research was carried out in the Department of physics, Nasarawa State University, Keffi, from September 2017 to April 2018. Methodology: Fifteen (15) samples each were taken from various locations from the rice fields in Keffi, Kokona, Karu, Nasarawa, and Toto respectively. Rice grain samples were dried in an open air at an ambient temperature to constant weight. Husks were removed. Then, the grain rice samples were pulverized and were passed through a 2.00 mm sieve and stored in closed polyethylene bags for irradiation using ECLIPSE Ш Energy Dispersive X – Ray Fluorescence (EDXRF) XR–100 CR spectrometer supplied by AMTEK INC. MA; USA. Results: The values of contamination factor of rice samples from the study area were in the order of Zn < Cu < Ni < Cr < Pb and are all less than 1, indicating a ‘low risk’ of contamination with the value of Cd >> 6 presenting a very high contamination risk of Cadmium. The Pollution Load Index value observed in Nasarawa West were in the order of Nasarawa (0.0683) < Keffi (0.0773) < Toto (0.0972) < Kokona (0.0988) < Karu (0.1389) and are all less than unity (1), indicating that the rice samples were not polluted by Cd, Cu, Cr, Ni, Pb and Zn. Conclusion: Findings from this study will help in making policies and preferring solution to public health related issues and further studies may be important.
