“…The construction waste in most countries is transported to the suburbs for open stacking or traditional landfilling without any treatment [ 6 ]. Thus, waste not only occupies extensive areas of land, but also affects soil and groundwater environments in the vicinity of the construction waste dump [ 7 , 8 , 9 ]. Moreover, during the long-term stacking of construction waste, a large amount of dust is released [ 10 ].…”

“…Roussat et al [ 16 ] research showed that demolition waste can contain arsenic, fluoride, chromium, cadmium, sulfate, dissolved organic carbon (DOC), and polycyclic aromatic hydrocarbons. Somasundaram et al [ 8 ] detected heavy metals, such as Cr, Hg, and Zn, in concrete and cement waste. They emphasized that the presence of heavy metals in construction waste is largely determined by the source of construction waste.…”

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 leachate generally contains four kinds of pollutants: dissolved organic matter, inorganic large components, heavy metals, and heterogeneous organic compounds [4]. There are lots of heavy metals in the leachate, due to the high heavy metal contents in construction waste [5]. The heavy metals and other harmful substances penetrate into and gradually accumulate within the soil, posing a threat to the ecoenvironment and human health.…”

This paper attempts to identify the content distribution of heavy metals in the soil around a construction waste landfill, and evaluate their impacts on human health. Firstly, parallel samples were collected from the soil in the study area. Then, seven heavy metals, namely, Fe, Cr, Pb, Cu, Hg, As and Cr, in the soil samples were detected and tested by inductively coupled plasma emission spectrometry, inductively coupled plasma mass spectrometry, and atomic fluorescence photometry, and the vertical distributions of these heavy metals were determined. After that, the cumulative risks of heavy metals in the soil were evaluated by single index method and Nemerow index method. Finally, these heavy metals were subjected to health risk analysis. The results show that the vertical distribution of Cu changed significantly in the soil around the landfill; the cumulative pollutions of Fe, Cu, and Hg in the soil reached the heavy level; the non-carcinogenic risks of As and Cr are relatively high, while Cr poses a carcinogenic risk to the human body. The research results provide effective data support to the site selection and operation of construction waste landfills.

“…The amount of C&D waste generation in the European Union was reported about 461 million tons annually (6). In South Korea, C&D waste equals 49.9% of the to-tal generated waste with the production rate of 68 million ton/year (7). The generation rate of C&D waste in the UK estimated about 100 million tons per year (8).…”

Construction and Demolition Waste and Its Management Challenges in Iran: A Case Study in Tabriz City

et al. 2019

View full text Add to dashboard Cite

Background: The management of construction and demolition (C&D) waste is among the fastest-growing concerns in Iran. Moreover, the basic prerequisites for the effective performance of every waste management program are the accessibility of adequate and precise data on characteristics and its current management condition. Objectives: Estimating the amount of C&D waste in Tabriz metropolitan city (Iran) was one of the key aims of the current study. Another objective of this study was to evaluate of C&D waste handling and their final disposal. Methods: The C&D waste generation rate was estimated according to the waste weight per area of construction and demolition in Tabriz. Then the C&D waste management condition was assessed using a checklist, visiting the disposal site, intervening authorities, and analyzing scientific databases. Results: The amount of C&D waste generation rate in the Tabriz city was estimated to be in the range of 167034 to 848480 ton/year or 0.114 to 0.534 ton/year per capita and 2.267 ton/m 2 of demolition. In this area, like most other parts of the country, no scientific and systematic program was observed for source reduction (reduce, reuse, and recycle of the C&D waste). Due to the non-availability of any standard disposal site, all the C&D waste (except for some recycled items such as metals) were deposited at the nearest distance from the city in public lands, waterways, valleys, roadsides and so on. Conclusions: According to the findings there is a great urgent need for applying specific practical policies, rules, and regulations for source reduction (reduce, reuse, and recycle (3R)) of C&D waste. Moreover, a central disposal site should be allocated to dispose of the remaining C&D waste according to the environmental and health considerations.
