In this paper, the contents of four typical metals (Pb, Cd, Hg, and As) in asparagus, water, and soil from Chongming Island were quantitatively determined by inductively coupled plasma mass spectrometry (ICP-MS). The contents of these metals in asparagus showed a common rule of Pb > As > Cd > Hg in different harvest seasons and regions. Significant seasonal differences were found in the contents by difference analysis, but no obvious regional differences were observed. Furthermore, the asparagus did not accumulate these four metals from the soil in Chongming Island by the assessment of bio-concentration factor. The asparagus was proved safe by the analysis of single-factor pollution index and Nemerow pollution index. Through combining the analysis of the above indexes and the geological accumulation index, we found that 51.62% of soil samples were mildly polluted by cadmium. The results of health risk analysis showed that the risk value of children was higher than that of adults under oral exposure, but the four metals in asparagus possessed no obvious risk to health. The above assessments illustrate that the daily consumption of asparagus in Chongming Island will not cause potential health impacts. It is of benefit to ensure the quality and economic interests of asparagus planting in Chongming Island through the investigation of this study.

“…Sources include historically emitted leaded gasoline, nonferrous (brass and bronze) foundries, smelters, lead-acid-battery manufacturing, iron and steel production, power plants (refineries/coal burning), landfills, sewage sludge incinerators, waste incinerators, hazardous waste sites, and older homes that contain lead-based paint/pipes [ 12 ]. Lead emissions are common from industrial facilities lacking adequate air emission control equipment from coal burning power plants [ 13 , 14 ], coking operations [ 14 , 15 ], iron and steel manufacturing [ 16 , 17 , 18 ], oil refining [ 16 , 19 , 20 ], smelting [ 17 , 21 , 22 ], and waste incineration [ 16 , 17 , 23 ]. All these facility types, accompanied by emission deregulation, a lack of enforcement to existing regulatory limits, and limited air pollution control equipment, contribute airborne and deposition lead pollution to the DMA and especially the City of Detroit located in Wayne County [ 1 ].…”

This research investigates the relationships between airborne and depositional industrial lead emission concentrations modeled using Environmental Protection Agency’s (EPA’s) American Meteorological Society/Environmental Protection Agency Regulatory Model (AERMOD) and childhood blood lead levels (BLL) in the Detroit Metropolitan Area (DMA) 2006–2013. Linear and mediation interaction regression models estimated the effects of older housing and airborne and depositional lead emission concentrations on black and white childhood BLLs, controlling for neighborhood levels of racial isolation and poverty—important social structures in the DMA. The results showed a direct relationship between airborne and depositional lead emissions and higher childhood BLL, after controlling for median housing age. Lead emissions also exacerbated the effect of older housing on black and white children’s BLLs (indirect relationship), after controlling for social structures. Findings from this research indicate that black and white children exposed to lead-based paint/pipes in older housing are further impacted by industrial lead pollution that may lead to permanent neurological damage.

“…In this study, the human health risk evaluation model proposed by the technical guidelines for the risk assessment of soil contamination of land for construction in China (HJ 25.3-2019) was used. This model is usually divided into two parts: cancer and noncancer submodels (Hu et al, 2017;Wang et al, 2020). Since heavy metals are nongaseous pollutants, the human health risks of heavy metals in the remediated soil are primarily attributed to oral ingestion, skin contact, and direct inhalation.…”

The centralized utilization of heavy-metal-contaminated soil has become the main strategy to remediate brownfield-site pollution. However, few studies have evaluated the ecological and human health risks of reusing these remediated soils. Considering Zn as the target metal, systematic pHdependent leaching and the Community Bureau of Reference (BCR) extraction were conducted at six pH values (pH = 2, 4, 6, 8, 10, 12) for the remediated soil treated through thermal curing. The pHdependent leaching results showed that with the formation of ZnCr 2 O 4 spinel phases, the remediated soil exhibited strong inherent resistance to acidic attack over longer leaching periods. Furthermore, the BCR extraction results showed that the leaching agent pH value mainly affected the acid-soluble fraction content. Moreover, a strong complementary relationship was noted between the leaching and acid-soluble fraction contents, indicating that the sum of these two parameters is representative of the remediated soil risk value. Therefore, we proposed a two-step calculation method to determine the sum of the two heavy metal parameters as the risk value of remediated soil. In contrast to the traditional one-step calculation method, which only uses the leaching content as the risk value, this two-step calculation method can effectively avoid underestimating the risk of remediated soil.
