“…2 ranges from 0.03±0.01 -0.06±0.03 mg/kg with an average mean value of 0.04±0.01 mg/kg. The concentration in the study areas were observed to be lower than the values reported by Shingu et al [19,21,26,47] in dust samples collected in Yola, Mubi and Abuja. Similar high values compared to the concentrations in this study were also reported by Ogundele et al [29] in soil samples collected in heavy traffic roads in the North Central Nigeria.…”

“…Zinc owing to its heat conducting properties are used in the production of brake linings, which means that the continual mechanical abrasion of the vehicles could release quantum of Zn particles. Similarly, engine oil combustion processes and attrition of motor vehicle tire could also release Zn into the environments [19,58]. Even though Zn is considered least toxic element and very essential component of healthy diet, beyond the PL limits could lead to health-related complications such as nausea, vomiting, diarrhea, fever and lethargy.…”

“…The environmental menace associated with such heavy traffic activities attracted series of research on roadside soils, waterways and vegetation's along Nigeria highways [2, 10,[15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. These studies used heavy metal enrichment in roadside plants, dust or soils as an indicator to estimates the pollution levels generated by vehicular activities with some attempt toward establishing the ecological associated risk.…”

In this study, the health risk caused by heavy metals exposure to communities along Mubi-Yola highways was evaluated. Samples from Mubi, Hong, Gombi, Song, and Gerei were collected and analyzed for Lead (Pb), Cadmium (Cd), Chromium (Cr), Zinc (Zn), Cupper (Cu), and Nickel (Ni) using Atomic Absorption Spectrophotometer (AAS). The mean concentrations of the metals used for the risk assessment were observed to fall in this order Zn>Pb>Ni>Cu>Cd>Cr. The noncarcinogenic risk based on the target hazard quotient (THQ) and human health index (HI) values for each exposure pathway and for each metal were observed to be less than (<) 1 which means, exposure to the heavy metals has no immediate risks for both the adults and children in the settlements. The lifetime cancer risk (CRI) for the metals for both the ingestion (CRI Ing ) and inhalation (CRI Inh ) exposure pathways were observed to pose no lifetime carcinogenic risk. The CRI for all the exposure pathways and for all age categories were <10 -4. Similarly, the combine Bwatanglang et al.; JSRR, 23(1): 1-13, 2019; Article no.JSRR.48137 2 effect or total cancer risk (TCRI) for each exposure pathway show high probability for carcinogenic risk by ingestion route compared to exposure by inhalation. The order of exposure were observed to be adults

“…Heavy metals pollute both soil and plant and so it is necessary to examine the state of the polluted soil and plant and establish what influence heavy metals have on both. Heavy metals have great significance due to their toxicity and accumulative behaviour or and are not biodegradable (Shinggu et al, 2007). Surface soil may act as carriers and possible source of pollution, since the mobility of these metals is such that remain in upper layers without regard to soil type.…”

ABSTRACT:A literature survey has shown that no study has investigated the oral bioaccessibility of PTEs in Nigeria dusts. Studies on human health risk of PTEs from urban Nigeria dust have been based only on total elemental concentrations. Whilst this protocol is useful in assessing human health of PTEs, it could lead to an over estimation of the risk considering the elemental sequestration in the dust samples. This study deviated from previous studies by examining the total concentrations as well as the oral bioaccessibility of 8 PTEs in 15 urban dust samples collected from Abakaliki, Ebonyi State, Nigeria. The result showed that high concentrations of Pb (ranging from 236 -1815 mg/kg) were observed in 5 locations. The Unified Bioaccessibility Method (UBM) was used to investigate the oral bioaccessibility of these PTEs in the urban dust samples. The result revealed that all the PTEs were more bioaccessible in the gastric phase that the gastric + intestinal phase. The lead tolerable daily intake (TDI), as well as the bioaccessible TDI, was computed and results compared with a guideline value. © JASEM http://dx.doi.org/10.4314/jasem.v18 i2.13.Introduction: The occurrence and distribution of high concentration of PTEs in urban dusts have been widely reported (Okorie et al., 2012;Xinwei et al., 2009;Al-Khashman, 2007). They sources are also well documented (Wei et al., 2010;Manasreh, 2010). The presence of these PTEs in urban dusts is a potential threat to human health and the ecosystem in general. This is because these elements could enter the human body via the exposure pathways (oral ingestion, inhalation and dermal absorption) (Aelion et al., 2008). In addition, it has been reported that these PTEs have irreversible adverse effects on humans particularly children due to their pica behaviour, physiology, unique exposures and special vulnerabilities (Landrigan et al., 2000). This makes children at a higher risk as their immature organs tend to be more susceptible to PTEs than other contaminants (Egeghy et al., 2011).A literature survey has shown that only a few authors (e.g. Shinggu et al., 2007;Mashi et al., 2005) have investigated the occurrence of PTEs in Nigerian urban dusts, but none for Abakaliki, Ebonyi State. The survey also showed that all the studies determined only the total elemental concentrations. No study has investigated the bioaccessibility of PTEs in Nigerian dust. It is to be noted that in assessing the human health risk of PTEs, it is not the total concentration of PTEs in urban dust that is of greatest concern but the fraction that is released in the human body (bioaccessible fraction) when dust is ingested. Thus, the use of only total elemental concentration in assessing human health risk of PTEs could be seen as an over estimation of the risk associated with oral ingestion of soil based on the principle of PTEs sequestration within various heterogeneous dust samples; a scenario whereby the total elemental content present in the ingested dust is not readily accessible for absorption and trans...
