“…For non-carcinogenic risk, this study revealed that the ingestion of road dust appeared to be the primary exposure route for toxic metals to both age groups, followed by dermal contact and inhalation, respectively (Table 2). Similar results were also reported in many other scienti c works (Dehghani et al 2017;Rahman et al 2019;Heidari et al 2021;Yesilkanat and Kobya 2021). Both age groups showed the highest ADI ing , ADI inh and ADI dermal for Pb, and lowest ADI ing and ADI inh for As, although the lowest ADI dermal was found for Cd.…”

“…Multivariate statistical analysis has been widely used in grouping and identifying the source of pollution in different environmental mediums (Yang et al 2011). Positive matrix factorization (PMF) is a multivariate statistical model which has been used for source apportionment, and recently many researchers applied it for environmental samples (Jiang et al 2020; Kolakkandi et al 2020;Men et al 2020;Guo et al 2021;Heidari et al 2021;Zhu et al 2021). PMF showed restriction to non-negative values to get more meaningful factors and provide numerical information regarding the contribution of every source type (Men et al…”

This study investigates pollution levels, source apportionment, ecological and human health risks associated with toxic metals (Pb, As, Hg, Cr, and Cd) in road dust from the most populated Dhaka city and a connected major highway in Bangladesh. The mean concentration of Pb, Hg, and Cd were 1.3, 29.3, and 13.2 times higher than their corresponding background values with spatially uneven distribution all over the study area. Metal pollution indices, the geo-accumulation index (Igeo), NIPI, PI, indicated extreme contamination at many sites depending on local environmental factors. The potential ecological risk (\({\text{E}}_{\text{r}}^{\text{i}})\) revealed that 84% and 54% of samples showed the extreme ecological risk for Hg and Cd pollution, respectively. On the other hand, the potential ecological risk index (PERI) and nemerow integrated risk index (NIRI) showed that most sampling sites suffered high to extreme ecological risk. Source apportionment using positive matrix factorization (PMF) identified coal combustion and gasoline (50.14%), traffic exhaust (35.26%), and industrial and agriculture activity (14.60%) were the main source of toxic metals of the study area. Non-carcinogenic health risk indicated that adults are more vulnerable than children, and hazard index (HI) of Hg for both age groups and Cd for adults were significantly higher than the safe level. The carcinogenic risk (CR) levels of toxic metals were acceptable (10− 6 to 10− 4), although the maximum limit of Cr for children and As for adults was close to the unacceptable limit (10− 4). Continual exposure to toxic metals through road dust might develop lifetime cancer risk in local inhabitants.

“…Metal(loid)s are present in the natural environment but their anthropogenic sources which include domestic, industrial, and agricultural wastes have exacerbated their levels in aquatic systems. Heavy metals are of great concern and a growing problem worldwide, contributing to 9 million excess deaths ( Heidari et al., 2021 ; Dippong et al., 2017 ) and could cause health problems ( Dippong et al., 2020 ). Sources of heavy metals in aquatic systems include leaching of rocks especially by rainwater, atmospheric deposition of airborne dust or industrial emissions, forest fires, and vegetation ( Dippong et al., 2017 ), and fertilizers, animal agriculture wastes, etc.…”

Farmed crustaceans are an important component in addressing the rising animal protein demand. The present study determined the concentrations of fourteen elements (Ag, As, Be, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Sn, Pb, and Zn) in the edible abdominal muscle of cultured freshwater crayfish species ( Faxonius virilis; Procambarus acutus acutus ) from Missouri. Also, this paper describes the dietary intake and the human health risks from the consumption of crayfish muscle in the adult population. Overall, 172 animals were captured between February 2017 and January 2018 for assessment. Concentrations of metals (Ag, Be, Cd, Cu, Co, Cr, Fe, Mn, Ni, Pb, Sn, Mo, and Zn) and metalloid (As) in the muscle tissue were determined after microwave-assisted acid digestion by ICP - OES. Health indices (EDI/EWI: estimated daily/weekly intakes; THQ: target hazard quotient; TTHQ: total target hazard quotient; ILCR: incremental lifetime cancer risk; and ∑ILCR: cumulative lifetime cancer risk) were calculated and compared to thresholds. Of all samples, the highest concentrations (mg kg −1 wet weight) of metal(loid)s in muscle were Ag (0.11), As (3.15), Be (0.21), Cd (0.11), Co (0.32), Cr (1.22), Cu (107), Fe (23.0), Mn (8.54), Mo (0.62), Ni (2.65), Pb (1.76), Sn (5.91), and Zn (19.2). In both species, the average As, Cd, and Zn concentrations were below the legal limits. However, the levels of Cu, Pb, and As, in some samples, were in exceedance of the maximum levels. In both species, a significant correlation (p < 0.05) was observed between the carapace length (CL) and animal body weight (BW). In P. acutus , CL, BW, and animal total length were homogenous (p > 0.05) among the sexes. Non-parametric Kruskal–Wallis test results indicated significant differences (p < 0.05) in the levels of As, Be, and Zn in F. virilis , and Be and Cr in P. a. acutus among the genders. Significant inter-species differences (p < 0.05) were observed in the levels of Be, Ni, and Pb and the growth factors. The EDI/EWI values were below the permissible limits. THQ and TTHQ values, being below 1.0, indicated no probabilistic health risk. Regarding carcinogenic risk, only As and Ni indicated cancer risk (ILCR >10 −5 and ∑ILCR >10 −5 ) to the adult population. High metals/metalloid exposure from crayfish muscle consumption posed potential health hazards to the adult population.

“…According to the investigation, the recycled products are used primarily for industrial purposes, including copper smelting raw materials, cables, wood preservatives, fungicides, etc., but some of the recycled products flow to the feed processing industry and even to the food processing industry [5]. Previous studies have established that heavy metals can cause anemia, bronchitis, and even damage to the nervous system [6] through ingestion, inhalation, and dermal contact [7]. For example, cadmium can replace calcium in the bone when it goes into the body, causing severe softening of the bones and also causing dysfunction of human organs [8].…”

With the vigorous development of the 5G industry, the characteristic hazardous waste, spent coppery etchant, was also produced in large quantities. In recent years, there are many companies that have begun to collect spent coppery etchant for the purpose of producing recycled products, such as copper sulfate, copper oxide, basic copper chloride, and copper powder, which often contain large amounts of heavy metals. However, due to the lack of relevant standards and applicable regulatory measures, some of the recycled products flow to the feed processing industry and even to the food processing industry. This study investigated the pollution status of heavy metals in recycled products of spent coppery etchant and evaluated the impact of recycled products exposure on human health. The results showed that the content of Zn was the highest, which was 21 times higher than the corresponding standard limit. Human health risk assessment indicated that the hazard quotients of As account for 87.5% of the entire HI value, while the average carcinogenic risk values of As for copper sulfate, copper oxide, basic copper chloride, and copper powder are 1.09 × 10−5, 3.19 × 10−5, 1.29 × 10−5, 7.94 × 10−6, respectively. Meanwhile, suggestions on the supervision of recycled products and the concentration limits of heavy metals in recycled products were put forward.
