“…Furthermore, Bannae and Taheri (2019) observed that snails exposed to sewage containing heavy metals had significantly reduced total antioxidant capacity and increased lipid peroxidation with elevated activities of LDH, alanine transaminase (ALT), and aspartate transaminase (AST). In a similar study to ours, evaluation of soil around Ashaka cement factory PLC, in Northern Nigeria, Kolo et al (2018) found chromium, Pb, and nickel levels to be remarkably high. Blood analysis of the adult and children around the Ashaka cement factory was found to contain a high level of chromium (carcinogenic metal).…”

“…The potential health hazards posed by heavy metals remain a global concern especially in the developing countries, where treatment and elimination of effluents are inadequate or nonexistent (Banaee and Taheri, 2019). Cement kiln dust is a particulate pollutant that is generated from cement production factories during blasting of raw materials, grinding of cement clinker, and packaging or loading of finished cement (Kolo et al, 2018). The cement kiln contains heavy metals, such as lead (Pb), cadmium (Cd), and arsenic (As) (Gupta and Singh, 2011; Schemback, 1998), thus making it a source of environmental pollutant through which the workers and public in and around the cement factories are exposed to heavy metals (Gupta and Singh, 2011).…”

“…The cement kiln contains heavy metals, such as lead (Pb), cadmium (Cd), and arsenic (As) (Gupta and Singh, 2011; Schemback, 1998), thus making it a source of environmental pollutant through which the workers and public in and around the cement factories are exposed to heavy metals (Gupta and Singh, 2011). When these metals are released with the kiln, they spread over wide areas aided by the wind and finally settle on soil through which human exposure could ensue (Kolo et al, 2018). Indeed, exposure to Pb may disrupt cellular redox state, inhibit heme biosynthesis (Mani et al, 2018), and cause mitochondrial apoptosis (Jin et al, 2017).…”

Some snails ( Achatina spp) can be used as a biosensor of heavy metal poisoning. This study thus estimated some heavy metal levels, antioxidant markers, and lipid profiles of snails handpicked around cement factory vicinities in Ogun State, Nigeria. Snails and soil samples were collected from Oke, Ewekoro, Papalanto, and Mowodani Imeko-Afon (control site). Lead (Pb), cadmium (Cd), and arsenic (As) levels were estimated in the soil, snail foot, hemolymph, and shell using Atomic Absorption Spectrophotometry. Triacylglycerol (TAG), phospholipids (PHOL), cholesterol (CHOL), malondialdehyde (MDA), and reduced glutathione (GSH) levels, as well as glutathione- S-transferase (GST), lactate dehydrogenase (LDH), and arylesterase (AR) activities in the hemolymph, were estimated spectrophotometrically. The snails collected from the Oke site had the highest foot Pb (274.66 ± 13.50 mg/g tissue), CHOL, TAG, PHOL levels, and GST activity when compared with other sites. Snails collected from Papa had the highest Cd levels (1.79 ± 0.74 mg/kg), As (1206 ± 18.87 mg/g tissue) in the foot, and LDH activity, while Ewekoro snails had highest MDA levels and AR activities but the lowest GSH levels. Additionally, there were negative correlations between the heavy metal levels and the activities of GST and AR as well as GSH levels, while positively correlating with LDH activity and MDA level. Workers and the general public around cement factories are at a greater risk of heavy metal-induced pathologies. More so, consumption of snails around these sites may be deleterious to health.

“…The life time cancer risk (LTCR) was determined for several of the metals (Cd, As, Cr, Ni, and Pb), oral exposure being considered to bear carcinogenic risks. The cumulative cancer risk arising from exposure to metal carcinogens in consumed foodstuffs is assumed to be a linear sum of each of the individual metal risks [40,43,44], and can be obtained by Equation (6):…”

While the consumption of seaweed and seaweed-based products is very common amongst East Asian nations, forming a notable component of the daily diet, relatively very few studies have concerned the concentrations of heavy metals in these together with potential effects on human health. The present study analyses the concentrations of 17 elements in locally resourced seaweed, also assessing potential noncarcinogenic and carcinogenic risks. The samples were ground, homogenized, and quantified using the ICP-OES technique. It has been found that the essential elements K, Ca, Mg, Zn, and Na typically show concentrations somewhat greater than a number of potentially toxic metals, in particular, Cd, Pb, Ag, and As, with exceptions being Ni, Cr-VI, and Si. Statistical analysis indicates all of the latter to have similar origin, with increased concentration of these metals within the marine ecosystem. While the daily estimated intake of most metals is seen to be within the daily dietary allowance level recommended by various international organizations, the noncarcinogenic risk shows a value greater than unity, estimated via the hazard quotient. This indicates a potential for adverse effects to health arising from consumption of the sampled seaweed. The carcinogenic risk resulting from nonessential elements shows values greater than the United States Environmental Protection Agency (US-EPA) reference limit of 10−4. Considering the nonbiodegradability of heavy metals and metalloids and their potential accumulation in seaweed, there is need for critical examination of metal levels in the seaweeds obtained from the present study locations, together with the introduction of practices of removal of heavy metals via bio-adsorbent techniques.

“…[1][2][3][4] Thus, determining whether the soil needs remediation or not is important for appropriate evaluation of Pb risk to humans. The amount of Pb in soil is usually 2-200 mg kg -1 , 5,6 which is difficult to determine accurately by available analytical methods because of the low content and interference effects. Therefore, a rapid and accurate analytical method is needed to monitor Pb in solid environmental samples.…”

Lead (Pb) is a non-essential but extremely noxious metallic element, which is important for the assessment of environmental pollution. A simple and high throughput method involving fast heat extraction slurry sampling electrothermal atomic absorption spectrometry (HESS-GFAAS) was developed to detect trace Pb content in geological standard reference materials (SRMs). Compared with the traditional digestion method, the HESS-GFAAS method greatly reduces the time of sample pretreatment. The HESS-GFAAS technique improved Pb recovery and precision compared to conventional slurry sampling techniques. This optimized HESS-GFAAS procedure was performed as follows: first, the sample was added into 1 mL HNO3, 1 mL HCl and 1 mL HF, followed by heating for 30 min at 120 ℃ on a heating block; Next, dilute the solution with 50 mL water, and finally, the solution was introduced into a graphite tube with Pd(NO3)2-NH4H2PO4 as the mixed matrix modifier and analyzed by the GFAAS with a Pb electrodeless discharge lamp (EDL). To eliminate the interface of the geological sample matrix, the method of additions calibrate was used for Pb determination in geological samples. The results for 20 of these materials were in good agreement with the reference values. The characteristic mass and limit of detection for Pb based on the integrated absorbance for a 0.2% (m/v) sample were 14.8 ± 0.8 pg and 0.035 mg kg-1 , respectively. The accuracy (96.05-102.4% recovery) and precision (0.13-2.07%) of this procedure are illustrate by the results obtained for the 20 geological reference materials. The proposed method shows great potential for the determination of trace Pb in geological samples.
