“…Cadmium content of crayfish in this study is a cause for serious concern because of its diverse toxic effects including teratogenicity, carcinogenicity, nephrotoxicity, endocrine and reproductive toxicity compounded by its long biological half-life (20 -30 years in humans), low rate of excretion from the body and storage in soft tissues (Liver and Kidney) (Rani et al, 2014). Higher cadmium concentrations ranging from 0.17 -1.94 Mg/kg and 0.4-1.40 Mg/kg were reported for crayfish obtained from creeks in Rivers State, Nigeria and from Sabo U. U.

Intense pressure from both onshore and offshore oil exploration and exploitation activities, together with the accompanying urbanization and industrialization has resulted in massive contamination of land and water resources in Niger Delta, Nigeria. Whereas crayfish is very sensitive to contaminant in the aquatic environment and constitute an important part of human diet, its quality and safety from environmental pollutant is of serious health concern. Evaluation of dietary intake, potential carcinogenic and non-carcinogenic risk of lead, cadmium, mercury and arsenic exposure via consumption of dried crayfish purchased from major markets in Calabar, Nigeria was carried out between June and August 2021. Thirty-six composite samples of dried crayfish purchased from 180 vendors were used for the study. Heavy metals concentrations were determined using Atomic Absorption Spectrophotometer (Model AA-6800, Japan) after wet digestion. Metals concentrations (Mg/kg) were of the ranges 0.02 -0.24, 0.14 -0.86, 0.32 -0.72, 0.04 -0.19 for Pb, Cd, Hg and As respectively. The mean content of cadmium and mercury exceeded FAO/ WHO and Commission of European Communities maximum levels for crustaceans. Average Estimated Daily Intake for each of the metals was found to be above the recommended daily intake level except for arsenic. The average estimated daily intake values for Cd and Hg were also above the tolerable upper intake level.

“…Heavy metals are generally referred to as those metals which possess a specific density of more than 5 g/cm 3 and adversely affect the environment and living organisms [1]. They are elements that contaminate food and make them harmful to human health when present in quantities that are higher than the permissible limit [2]. Some trace elements such as arsenic (As), cadmium (Cd), mercury (Hg) and lead (Pb) are toxic even at small concentrations [3].…”

AIM: This study investigated the concentration of heavy metal (Arsenic), taken up by waterleaf plant cultivated in three contaminated soil type namely; sandy, loamy and clay. The health risk associated in exposing the waterleaf plants was accessed from the different soil types at different treatment levels of 40mg/kg (low) and 80mg/kg (high) of arsenic. Methods: Three soil types namely; sandy, loamy and clay were spiked with 40 mg/kg and 80 mg/kg of arsenic. The waterleaf plant was grown on the spiked soil samples for the period of 2, 4, 6 and 8 weeks. Each soil sample was taken before the spiking of the soil to serve as the basal control soil sample. This will determine the content of arsenic in the soil. After the stipulated growth period, the soil sample was collected into a clean sample bottle likewise the waterleaf plant which was harvested, washed, oven dried and ground into a powdered form which was acid digested. The heavy metal content in both the plant and soils were determined by atomic absorption spectroscopy. Results: The results of arsenic concentration in waterleaf from loamy soil at 40 mg/kg were 0.118 mg/kg, 0.189 mg/kg, 0.295 mg/kg, and 0.332 mg/kg at weeks 2, 4, 6, and 8 respectively. At 80 mg/kg, arsenic concentrations in loamy soil were 0.200 mg/kg, 0.388 mg/kg, 0.612 mg/kg and 0.693 mg/kg respectively. For sandy soil, the concentration of arsenic in the waterleaf plant treated at 40 mg/kg were 0.083 mg/kg, 0.219 mg/kg, 0.279 mg/kg, and 0.310 mg/kg for weeks 2, 4, 6 and 8 respectively and 0.159 mg/kg, 0.400mg/kg, 0.572 mg/kg, 0.632 mg/kg at 80 mg/kg respectively while in clay soil, the arsenic concentration was 0.079 mg/kg and 0.167 mg/kg for weeks 2 and 4 at 40 mg/kg and 0.190 mg/kg and 0.320mg/kg for 80 mg/kg for weeks 2 and 4 respectively. No growth was recorded in weeks 6 and 8. The mean values of the arsenic concentration in the plant spiked with 40 mg/kg and 80 mg/kg respectively were significantly different (p<0.05)from each other but that for the loamy soil at 40 mg/kg was not significantly different (p>0.05).The Estimated Daily Intake for arsenic was <1, Target Hazard Quotient was < 1 and the Health Risk Index for adults that would be exposed to arsenic was <1 except for the loamy soil which was ≥ 1 at week 4 and 6 for treatment level 80 mg/kg. Conclusion: Arsenic concentration increases in the plant with increasing period of growth, while in the soil, the reverse occurs. The result shows that the waterleaf plant absorbed heavy metal (Arsenic) from the contaminated soils but at concentrations that do not pose any health risk within the experimental period of exposure. However, it is possible that with extended duration of exposure, consumption of plants exposed to contaminated soils with heavy metals could be hazardous.

Aim: Assess the levels of heavy metals: arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), and zinc (Zn) in three different sites of the major rice growing soils and determine its accumulation in the rice grown on the same site in Nnatu St Azuuiyi Udene, Abakiliki, Ebonyi State. Study Design: Soil and rice samples were collected from three different farm locations into properly labeled plastic bags respectively using a 9mm soil Augerin Nnatu St AzuuiyiUdene, Abakiliki, Ebonyi State. Methodology: The collected samples were air-dried, ground, sieved and acid digested. The heavy metals in the samples were measured by atomic absorption spectrophotometer PG instrument AA500 FPC model. Results: The Mean ± SD (mg/kg) of heavy metals in rice were; As: 0.0013, Cd: 0.001, Pb: 0.002, Zn: 0.3620. Cu: 0.001 in site 1 whereas in Site 2; As: 0.0013, Cd:0.001, Pb:0.002, Zn:0.5040, Cu:0. 001. In site 3, the metals in rice were; As: 0.0013, Cd: 0.001, Pb: 0.002, Zn: 0.1950, and Cu: 0.040 respectively. The levels in the soil samples in site 1 were; As: 0.0013, Cd: 0.001, Pb: 0.002, Zn: 1.932. Cu: 0. 0267. In site 2, As: 0.0013, Cd: 0.001, Pb: 0.002, Zn: 1.597, Cu: 0.1550 and in site 3. As: 0.0013, Cd: 0.001, Pb: 0.002, Zn: 3.383, Cu: 0.0730 respectively. The mean values for arsenic, cadmium and lead in the soil and rice samples, respectively, were not significantly different (P > 0.05) in the three different sites whereas, for copper and zinc, the mean values were significantly different (P < 0.05) from each other at the different spots with an elevated concentration of copper and zinc in the soil samples than in the rice samples. However, these values were far lower than the values indicated by the World Health Organization as hazardous. Conclusion: The rice samples grown in Nnatu St AzuuiyiUdene, Abakiliki is safe for consumption.
