Abstract Expanded urbanization particularly in developing nations have as of late become a significant source of worry because of their adverse consequences on the environment. This study was conducted to determine the extent of pollution, sources, and potential ecological and health risks associated with heavy metals in Akure region, Nigeria's soils and street dusts. Thirty-four samples including 16 soils and street dusts samples each were gathered with two control samples gathered from a suburb a long way from the city. To collect fine particles, they were air dried and sieved. Chemical analysis of samples werecarried out utilizing Atomic Absorption Spectrometer (AAS) at Sustainable laboratory, a certified laboratory in Akure, Nigeria. Metals analysed were: As, Cd, Co, Cr, Cu, Ni, Pb, Zn and Fe. Contamination, ecological and health hazard evaluations were carried out utilizing universally acceptable indices. Potential sources were disentangle utilizing measurable technique like bivariate, factor and hierarchical cluster analyses. Results uncovered that the mean amount of Pb, Zn and Fe in street dusts were: 32.33 mg/kg, 72.53 mg/kg, and 115.21 mg/kg separately while in soil tests it was 34.34 mg/kg, 67.76 mg/kg, and 115.21 mg/kg. The examination further showed that metals particularly Cr present slight to high ecological dangers. Health hazard evaluation uncovered that the occupants of the area particularly kids are more inclined to non-cancer-causing health risks. Metals were mostly from anthropogenic sources. To reduce the impact of toxic metals in the city, it is proposed that ecological enactment and mindfulness be practiced.

AbstractHeterogeneity between ambient and personal exposure to heavy metals has been documented. However, few studies have investigated potential health risks posed by inhalational exposure to airborne heavy metal(loid)s at the individual level. A total of 404 personal fine particles (PM2.5) samples were collected from 61 adult residents (aged 18–63 years) in Hong Kong during 2014–2015. Heavy metal(loid)s were analyzed using energy dispersive X-ray fluorescence. Among the analyzed heavy metal(loid)s, zinc (Zn) was the most abundant component in personal PM2.5, followed by lead (Pb), copper (Cu), and vanadium (V); cobalt (Co) and cadmium (Cd) were not detectable. Health risks of personal exposure to heavy metal(loid)s via inhalation were assessed for adults, including non-cancer risks that were characterized by hazard quotient (HQ) and hazard index (HI). The results indicated that non-cancer risks of heavy metal(loid)s were attributable to Cu, with a 95th HQ value > 1. Arsenic (As) and hexavalent chromium [Cr (VI)] were also significant contributors to inhalation cancer risks (> 1 × 10−6) for the adult participants. Finally, we employed a Monte Carlo simulation to evaluate the uncertainty associated with health risk assessment. The mean and median upper-bound lifetime cancer risk associated with inhalation exposure to carcinogenic heavy metal(loid)s exceeded the acceptable level (1 × 10−6) for adults. Traffic emission (including non-tailpipe exhaust), shipping emission, and regional pollution were significant sources of heavy metals. These findings suggest that emission controls targeting local vehicles and vessels should be given priority in Hong Kong.
