“…A model of health risk assessment (HRA) was developed to establish potential health risks posed to humans and caused by contaminants in different environmental compartments [1,6,9,27,51,52]. Since part of the investigated area is located within the industrial zone of the petrochemical industry, adequate equations for composite workers were used [35,36].…”

The pollution state and health risk assessment of potentially toxic elements (PTE) in soil and sediment samples of the petrochemical industry and its surrounding area are evaluated in this study. The pseudo-total contents of Ba, Cd, Co, Cu, Cr, Mn, Ni, Pb, V, Zn, As, Hg, and Se were measured by inductively coupled plasma–optical emission spectrometry (ICP/OES) in analyzed samples. Instead of determining total content, we performed aqua regia of the samples. The silicate matrix remained, and the quantities of elements that are within the silicate matrix do not represent an environmental danger. The soils from the chlor–alkali plant are highly polluted by Hg (the enrichment factor values were above 6000), and by Cu, Cd, Pb, and Zn, while the sediment samples from the wastewater channel are polluted with Cr, Cd, and Hg. The measured element contents are used for calculating health risk criteria for a composite worker (a worker who is exposed, long-term, during the work day) and for residential people. Hg is the element that mainly contributes to non-carcinogenic risks within the petrochemical area. The highest value of total carcinogenic risk obtained in the sediment sample from the wastewater channel, and the metal that mostly contributes is Cr. The areas closest to the petrochemical industry have higher values of health risk criteria parameters and pollution indices. The areas that are located further to the north and south from the petrochemical industry are less burdened with the analyzed elements, which is significant because the closest city and village are situated in those directions.

“…They suggested that the high levels of Pb in F 2 were a result of the complexation with humic substances formed by composting in presence of e-waste and Pb was the most bioavailable metal in their study. Furthermore, Rivera et al (2016) established Pb to be easily extracted with EDTA and Cd being associated with the exchangeable fraction. Takáč et al (2009) attributed metals extracted with EDTA as a potential mobilizable fraction with up to 99.6% of Pb in their study associated with this fraction.…”

Informal E-waste recycling can pose a risk to human health and the environment which this study endeavours to evaluate. The distribution of a number of heavy metals in soil from an informal recycling site in the largest market for used and new electronics and electrical equipment in West Africa was investigated. The potential bioavailability of heavy metals, extent of contamination, potential risk due to the recycling activities and impact of external factors such as rainfall were also assessed. The concentrations of all the heavy metals tested were higher in the area where burning of the waste occurred than at the control site, suggesting an impact of the recycling activities on the soil. The order of total metal concentrations was Cu > Pb > Zn > Mn > Ni > Sb > Cr > Cd for both the dry and wet seasons. The total concentrations of Cd, Cu, Mn, Ni and Zn were all significantly higher (p < 0.001) in the dry season than in the wet season. The concentrations of Cu (329-7106 mg kg), Pb (115-9623 mg kg) and Zn (508-8178 mg kg) were consistently higher than international soil guideline values. Using a sequential extraction method, the potential bioavailability of the heavy metals was indicated as Cd > Sb > Zn > Cu > Ni > Pb > Cr. When the risk was assessed using the Potential Ecological Risk Index (PERI), Cu was found to contribute the most to the potential ecological risk and Cd gave rise to the greatest concern due to its high toxic-response factor within the study site. Similarly, utilising the Risk Assessment Code (RAC) suggested that Cd posed the most risk in this site. This research establishes a high level of contamination in the study site and underscores the importance of applying the appropriate chemical speciation in risk assessment.

“…XRF spectrometry is based on the wavelength-dispersive principle, which states that individual atoms emit a relative abundance of X-ray photons of energy or wavelength feature that can be estimated (Weltje & Tjallingii, 2008). This technique has been applied in the examination of Earth materials from a range of settings and environments (e.g., Chalmers & Bustin, 2017;Löwemark, Jakobsson, Mörth, & Backman, 2008;Oyedotun, 2016;Özkul, Çiftçi, Tokel, & Savaş, 2017;Rivera, Giráldez, & Fernádez-Caliani, 2016;Sabaou et al, 2009). The wide range of XRF's uses is due to its capacity to provide probable higher precision and accuracy than alternative methods (Taggart, Lindsay, INWASCON …”

X-ray fluorescence (XRF) spectrometry is a well-known, well-established and widely applied technique in the determination of many major elemental compositions of earth materials. XRF confers the ability to analyse solid samples non-destructively through X-radiation. The orderliness and clarity of its emission spectrum, its great accuracy and precision make this technique a geochemical method of choice in mineralogy and investigation of the chemical composition of earth materials. There are limitations regarding the age and calibration of instruments, costs of setting up, matrix effects to be considered and the stringent sets of standards; however, XRF laboratory analyses remain the standard technique for providing high-quality geochemical data analyses in the investigation of earth elemental composition. With further improvements in XRF technology, it is expected that this technique will be of continued importance/utility in geological and geomorphological investigations.
