“…In addition, Pb levels (38,972 μg⸱m −2 ) for adults working at lead battery manufacturing sites in the UK were also much higher than that of the current study [ 41 ]. The difference could be largely explained by the relatively severe environment pollutant situation and the close human behavior (such as the occupational exposure) in those studies [ 42 ].…”

The soil environment contributes considerably to human exposure to metals. This study aimed to comprehensively compare children’s exposure to soil metals using different sampling approaches (i.e., hand wipe, indoor dust and outdoor soil) and assessment strategies, combing the method of external exposure evaluation and the correlation with internal biomarkers. Environmental exposure samples (hand wipe, outdoor soil and indoor dust), blood samples and child-specific exposure factors were simultaneously collected for 60 children aged 3 to 12 years from an area of northwestern China. Eight typical toxic metals were analyzed. Results showed that metal levels in hand wipes were associated with children’s age, years of residency and the ground types of the play areas. Hand-to-mouth contact was an important pathway for children’s metal exposure, with the corresponding oral exposure cancer risk to Cr already exceeding the maximum acceptable level. In comparison, metal concentrations in hand wipes were one to seven times higher than those in outdoor soil and indoor dust. Even greater discrepancies were found for the estimated exposure dose, which could lead to differences of several to dozens of times. In addition, Pb, Mn and Cr in hand wipes were significantly correlated with those in blood, whereas no relationships were found with soil and dust. This study indicates that the selection of different sampling and assessing strategies could lead to great differences in children metal exposure outcomes. It also suggests that hand wipe, which could reflect the true and integrated exposure level and the individual difference, serves as a better matrix to assess children’s metal exposure compared to soil and dust. Further studies should standardize the sampling method for hand wipes and verify its applicability for other age groups.

“…Perhaps most importantly, a dust wipe collects a broad spectrum of particles representing ingestion, inhalation, and dermal contact exposure pathways more closely. 12,13 Dust wipe sampling has been used to assess potential skin absorption and ingestion (particularly with respect to children) by contact exposure and uptake from a contaminated surface, 4 particularly for Pb contamination assessment. 14 While dust wipe sampling is oen used to assess Pb and asbestiform contaminants in indoor environments, 15,16 its application for assessing other trace metals and outdoor environments is less common.…”

“…In the past 10–20 y, urbanization and industrialization in these areas have developed at an unprecedented rate. Previous studies demonstrate that industrial activities always lead to a significant increase in the concentrations of heavy metals in dust [ 12 , 13 ]. Consequently, humans who live and work in the city–industry integration areas, specifically near the factories, may have more potential health risks due to high heavy metal exposure currently and in the future.…”

“…Consequently, humans who live and work in the city–industry integration areas, specifically near the factories, may have more potential health risks due to high heavy metal exposure currently and in the future. Existing studies to determine and monitor urban road dust heavy metal pollution levels have been focused on functional areas such as bus stations or parks [ 14 , 15 ], while the studies on the spatial variation of heavy metal concentrations have been focused on the areas around high pollution factories far away from residential areas [ 12 , 16 ]. There have been few studies focusing on the dust heavy metal contamination caused by the modern high-tech manufacturing factories, especially those located in the typical city–industry integration areas with dense populations.…”

Road dust samples around three typical factories, F1, F2, and F3, in the National Zhengzhou Economic and Technology Development Zone (ZETZ), China, were collected to study the variation in heavy metal concentration (As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn), pollution, and health risk with distance from the factories. The results indicated that the concentrations of all the elements near F1 were higher than near both F2 and F3. Apart from Co, Mn, and Cu in some dust samples, all the element concentrations were higher than the corresponding background values (BCs), to varying degrees. The spatial distributions of the heavy metals surrounding the factories followed the normal distribution. The peak values of element concentrations occurred at 300~400 m away from the factories, except for Hg, which continued increasing more than 500 m away from the factories. The fluctuation curves of the pollution load index value calculated according to the BCs for F1, F2, and F3 all had two peaks, a “small peak” and a “large peak”, appearing at about 30 m and 300 m, respectively. For the hazard index and the total carcinogenic risk, the peak values all appeared at 400 m, with the curves following the normal distribution. Exposure to road dust containing non-carcinogenic and carcinogenic elements around F1 was greater than around F2 or F3. In conclusion, our results provide a reference for pursuing effective prevention of dust heavy metal pollution around modern manufacturing factories.
