Levels and patterns of polycyclic aromatic hydrocarbons and polychlorinated biphenyls in municipal waste incinerator bottom ash in Zhejiang province, China

Plastic Degradation and Its Environmental Implications with Special Reference to Poly(ethylene terephthalate)

“…However, there is a significant trade-off in that incineration of plastics leads to the formation of numerous harmful compounds, most of which are released to the atmosphere [45]. PAHs, PCBs, heavy metals, toxic carbon-and oxygen-based free radicals, not to mention significant quantities of greenhouse gases, especially carbon dioxide, are all produced and released when plastics are incinerated [53][54][55][56][57]. The significant environmental drawbacks of plastic disposal via both landfill and incineration were the driving force behind the development of plastic recycling processes.…”

Polycyclic Aromatic Hydrocarbons in Soil Around Coal-Fired Power Plants in Shandong, China

“…Furthermore, the PAH concentrations in this study were higher than those in most e-waste recycling sites in Guangdong (1,230 μg/kg) and Taizhou (262.6-3,420.2 μg/kg; 330-790 μg/kg) in China [30][31][32]. The PAH concentrations in this study and other areas around the power plants were lower than those of a thermal desorption plant (3,338.2 μg/kg), municipal waste incinerator in Zhejiang (222.53-6,883.91 μg/kg), and manufacturing gas plant (1,669,300 μg/kg) [33][34][35]. By contrast, they were higher than those of fuel stations (0.82-62.98 μg/kg), urban highway (523 μg/kg), industrial areas (471.3 μg/kg), and municipal solid waste site (1,974 μg/kg) [36][37][38][39].…”

Emission, distribution and toxicity of polycyclic aromatic hydrocarbons (PAHs) during municipal solid waste (MSW) and coal co-combustion

“…A modified MSW sample was comprised of food residue (64.93%), wood waste (1.48%), paper (12.94%), textiles (3.11%), plastics (15.07%) and noncombustibles (2.47%) based on the literature and field research in Beijing, China (Zhou et al, 2014). Polyvinyl chloride was used to represent the plastics due to its high fraction in MSW in China (Shen et al, 2010;Yu et al, 2016). Food waste, wood waste and textiles were collected from a canteen and refuse collection station of a university, respectively.…”

“…Zhang et al determined the amount of PAHs in fly ash samples collected from a MSW incinerator and found that 3-and 4-ring PAHs were the principal constituents of PAHs . Similarly, the bottom ash obtained from a MSW incinerator was analyzed and the results showed that the patterns of PAHs were also dominated by 3-and 4-ring PAHs (Shen et al, 2010).…”
