“…Pb, Cr, As, Ni, V, and Co in the dust fall implies no contamination. The analysis results regarding the heavy metals in the construction waste soil obtained by Wu et al [ 40 ] showed that Cd, Zn, Pb, and Cu are characteristic pollutants of construction waste in landfills. Other studies show that in other countries in the world (such as Malaysia, Philippines, Laos, and Iran), Zn and Cr are the main heavy metal pollutants in the construction waste landfill soil [ 41 , 42 ].…”

In this study, a large construction waste dump in Beijing, China, was used as the study area. Nineteen effective atmospheric dust samples were collected. The mass fractions of 14 metal elements (Ca, Fe, Al, Mg, Mn, Zn, Cr, Cu, V, Pb, Ni, As, Co, and Cd) were determined for the samples using ICP-MS. The pollutants and the potential ecological risk levels of 10 different heavy metals were evaluated using the enrichment factor, geo-accumulation index, and a potential ecological risk assessment method. The results showed that the Ca, Fe, Al, and Mg contents in the dust fall were considerably high and accounted for 98.81% of the total mass of the analysed metals. Cd and Zn were the main metal contaminants in the dust fall in the vicinity of the construction waste dump, followed by Cu and Mn. The Cd, Zn, Cu, and Mn contents in the construction waste had a significant impact on atmospheric pollution within 250 m of the dump. Moreover, Cd had the largest contribution to the comprehensive ecological risk posed by the heavy metals in the dust fall and was determined to be the primary ecological risk factor in the atmospheric environment in the vicinity of the construction waste dump.

The issue of construction waste reduction has become a global focus, and analyzing the spatial and temporal distribution pattern of construction waste production and the influencing factors is of great significance for different regions to adopt scientific and effective reduction measures according to their own development characteristics. In this paper, panel data of 31 provinces in China are selected from 2013 to 2021 to present the spatial and temporal evolution pattern of construction waste production, and the spatial lag model (SLM) is used to analyze the influencing factors and effects of construction waste production from the perspective of economic and social development. It aims to explore the optimization measures and promotion strategies for construction waste reduction, and to provide reference and assistance for the global construction waste reduction cause. The study shows that China's construction waste production is mainly clustered in the eastern coastal area, with obvious spatial autocorrelation, and the clustering effect shows a trend of rising and then falling, with the peak point appearing in 2018. In terms of the influence effect, the demographic and affluence factors have a more obvious impact on construction waste production than the technological factors. There is a clear spatial spillover effect in the influence of all three aspects on construction waste production, in which urbanization, the scale of the construction industry, the per capita consumption level, the population size and the gross domestic product per capita are the main reasons for the spatial aggregation of construction waste production. Among the construction waste reduction strategies, in addition to the improvement of labor efficiency, the level of technological application, and the requirements of building codes, other strategies need to be considered according to the characteristics and current situation of the socio-economic development of each region. This study is an important reference for countries to analyze the situation of construction waste production and adopt reasonable reduction strategies.

In this study, to investigate the contamination characteristics and potential health implications of heavy metals in road dust of the typical county in central China, heavy metals (Cd, Co, Cr, Cu, Mn, Ni, V, Pb, Zn) in typical road dust with large traffic flow, in different functional areas of Yangxin County, were determined. The results of the geo-accumulation index (Igeo) showed that Co, Mn, Ni, and V were not polluted, while other heavy metals caused different degrees of pollution. According to principal component analysis (PCA), there were three main sources of heavy metals. The result of statistical analysis showed that heavy metal pollution in road dust mainly comes from traffic activities, industrial production activities, building pollution, and the natural environment. The carcinogenic and non-carcinogenic risks of children and adults were within the safe range, and hand–oral contact was the main exposure route of non-carcinogenic risks. The non-carcinogenic risk and carcinogenic effects of heavy metals in urban road dust were acceptable to children and adults. However, we should still pay attention to the impact of heavy metals on the ecological environment and human health.
