Can washing-pretreatment eliminate the health risk of municipal solid waste incineration fly ash reuse?

Characterisation of excavated fine fraction and waste composition from a Swedish landfill

“…Furthermore, using the fines as a cover layer can be only possible if the concentrations of zinc and copper are reduced to the Swedish EPA limits. This can be done by using the washing method (Wang et al, 2015) (this method will be studied further in a future planned study). The final chosen solution was to re-dispose the fine fraction as an inert waste, which was in accordance with the Swedish EPA limits.…”

Enrichment of heavy metals in fine particles of municipal solid waste incinerator (MSWI) fly ash and associated health risk

“…The onsite workers contacted heavy metals through three main routes of exposure: ingestion, inhalation, and dermal contact (Wang et al, 2015). To estimate the occurrence of negative health effects from the Dp10-5, Dp5-2.5, Dp2.5-1, and Dp1 particles in re-suspended fly ash dust during the disposal and recycling processes, risk assessment models and relevant parameters from the US EPA (EPA, 1989(EPA, , 2001Schoof, 2003;Wang et al, 2013) were used in this study.…”

Extending MoS2-based materials into the catalysis of non-acidic hydrogen evolution: challenges, progress, and perspectives

“…However, it is still doubted whether the dual active sites indeed have a driving role in the alkaline HER activity. It is likely that the boosted HER kinetics can be caused by the changed electronic structure after introducing the dualsite rather than the promoted water dissociation due to the functional separation of active sites [75,76]. The improved HER performance can also derive from the optimized HBE caused by the change of electronic structure on active sites when a second species is introduced.…”
