“…The presence of Pb, Ni, Cr, and Cd in the fish samples indicates that the dams and their aquatic resources have been subjected to pollution from various sources, including both point and non-point pollution. This finding is consistent with the results reported by (Durodola et al, 2019), which highlight the introduction of contaminants (both synthetic and organic) into aquatic environments due to industrialization and agricultural advancements. There were no significant differences (p > .05) in the concentrations of Pb, Ni, Cr, and Cd among the six dams.…”

This study aimed to assess the levels of certain heavy metals in tilapia fish (Oreochromis niloticus), as well as vegetables, and to evaluate the potential health risks associated with the presence of toxic elements from Dec. 2019 to June 2023. A total of 60 tilapia fish, 12 okra (Abelmoschus esculentus) and 12 bitter leaf (Vernonia amygdalina) from six major dams in Osun State were prepared for analysis using wet digestion with aqua-regia. The concentrations of heavy metals were measured using an Atomic Absorption Spectrophotometer (Shimadzu AA-630). The health risk associated with fish consumption was estimated using various parameters. Statistical analysis was conducted using the Statistical Package for Social Sciences (SPSS) version 16.0. The concentrations of micro elements followed the order of Fe > Zn > Cu > Mn in decreasing concentrations. These concentrations exceeded the permissible limits set by the World Health Organization (WHO) for Ni, Cd, Pb, and Cr, which are 0.6, 0.3, 0.3, and 0.7 mg L-1, respectively. The results obtained for okra and bitter leaf were within the limits established by the World Health Organization (WHO). Therefore, the presence of these metals indicates the need for close environmental monitoring of the six selected dams.

“…High levels of arsenic above permissible limit were reported earlier in about 46% beverages from Nigerian market [10]. Exposure to high doses of arsenic is toxic and can cause various health effects, such as irritation of the stomach and intestines, nerve injury and stomach aches [11,12].…”

Some commonly consumed differently packaged soft drinks were investigated for their levels of As, Cd, Co, Cu, Mn, Pb and Zn. This was done in order to evaluate the effect of container materials on the levels of potentially toxic metals in the drinks and the health related short and long-term implications of regular consumption of these products. Batches of differently packaged soft drinks (in glass bottles, cans and plastic bottles) in Nigeria were purchased from wholesale stores in Ile-Ife, Nigeria. Atomic Absorption Spectrophotometer (AAS) was used to quantify the total amount of metals in the acid digested samples. The study revealed that most of the analyzed potentially toxic metals were at concentrations above the recommended WHO and USEPA permissible limits. The effect of packaging materials on the concentration of some of the analyzed metals in the soft drinks was significant at 95% confident level. From the results of this study, it could be concluded that caution should be exercised regarding regular and consistent consumption of these soft drinks as such habit might constitute a significant source of exposure to potentially toxic metals.

“…The health of any herb growing on a particular soil environment depends largely on the health of the soil accommodating the herb and can be monitored using bioaccumulation factor (BAF). The consumption of contaminated herbs from e-waste disposal sites with high concentrations of heavy metals can cause health hazards to consumers (Odoh and Ajiboye 2019;Durodola et al, 2019;Mirosławski and Paukszto 2018;Abbas et al, 2017). The potential health risk of herbs/plants on human health after the consumption of contaminated plants can be assessed by the hazard quotient and hazard index.…”

Considering that about 80 % of the world population uses herbs for the treatment of illnesses and the contamination that is prevalent at electronic waste (e-waste) disposal sites, this study evaluated the concentrations of heavy metals and health risks in the use and consumption of Rhynchospora corymbosa, Pentodon pentandrus and Cyclosorus dentatus, herbs commonly found in electronic waste disposal site in Lagos State, Nigeria using appropriate standard methods. The mean concentrations of the heavy metals in the plant were: 100.78±0.91, 0.16±0.02, 25.68±0.44, 258.94±1.62, and 8.51±0.04 mg/kg for Pb, Cd, Ni, Cu and Cr, respectively. Pentodon pentandrus had the highest Pb, Cu and Ni concentrations, Cyclosorus dentatus had the highest Cd concentration while Rhynchospora corymbosa recorded the highest concentration of Cr. The bio-accumulation factor of Cu in Pentodon pentandrus and in Rhynchospora corymbosa and of Cr in Rhynchospora corymbosa were higher than 1. The estimated daily intake of Pb and Ni in Pentodon pentandrus, Cyclosorus dentatus and Rhynchospora corymbosa exceeded the Provisional Maximum Tolerable Intake, indicating an intolerable risk to the consumers’ health. The hazard index of each of the plants indicates that the cumulative health effects of the heavy metals would cause potential health hazards to the consumers. This useful information gives an accurate indication of the levels of contamination of the plants and the potential health risk effects of the consumption of these herbs from the dumpsite.
