Health Risks Assessment of Heavy Metal Pollution in the Soil-Crop System from an E-Waste Dismantling Area

“…The samples of soils were air-dried and processed in an agate-made mortar to pass through 60 meshes sieves for available state and 100 meshes sieves for total-volume, respectively [27]; The samples of vegetables were washed away sediment and other adherents using deionized water and dried until free of water, then crushed, and mixed well for analysis [21,28,29]; The soil-water ratio of 1:2.5 was adopted to determine the soil pH [30]; The soil and vegetable samples were digested with HNO 3 -H 2 O 2 -HF and then determined the content of Cr, Pb, Cr, and Cu through inductively coupled plasma mass spectrometry (ICP-MS, USA) [15]. To ensure accuracy, all samples were repeated and blank samples were added to keep the relative differences within 10% and the spiked recoveries within 95%-110% [31].…”

“…With the tremendous advancement of science and technology in recent years, the lifespan of electronic and electrical products has been shorter, thus forming a large amount of electronic waste. Electronic waste (e-waste) refers to discarded electronic products, consisting of all components and consumables that are part of the electronic products when they are disposed of [11]. Notably, nowadays e-waste is becoming an increasingly prominent source of heavy metals during dismantling and incineration [12][13][14][15].…”

Notably, nowadays e-waste is becoming an increasingly prominent source of heavy metals during dismantling and incineration [12][13][14][15]. According to a recent study, 53.6 × 10 6 metric tons of e-waste was generated in 2019, but most of it was exported illegally to developing countries [11].…”

“…Notably, nowadays e-waste is becoming an increasingly prominent source of heavy metals during dismantling and incineration [12][13][14][15]. According to a recent study, 53.6 × 10 6 metric tons of e-waste was generated in 2019, but most of it was exported illegally to developing countries [11]. However, China is one of the major recipients of e-waste all over the world, while it has been the highest generator of e-waste in the world (7.2 Mt) since 2017.…”

Sustainable Valorization of E-Waste Plastic through Catalytic Pyrolysis Using CO2

“…in the E-waste . Currently, the remaining E-waste has not been properly disposed, which is landfilled, incinerated, and illegally exported to developing countries. , …”
