With proper leaching tests, health hazards associated with municipal solid waste incineration (MSWI) ashes, i.e., incineration bottom ashes (IBA) and incineration fly ashes (IFA), can be quantitatively defined. However, it must be coupled with specific environmental scenarios to draw the proper conclusions. Several environmental stresses based on current management of MSWI ashes were herein simulated with laboratory leaching studies to understand their impacts. The impact of bulk metal recovery on the IBA leaching potential was firstly investigated, suggesting the promoted release for certain metals including those with a relative high content (> 1000 mg/kg) such as Ba, Cu, Pb and Zn. The impact of seawater was also simulated. Most metal release was altered with the new chemistry established. Batch leaching tests were further performed under both salty and acidic environment to understand their aggregated effects, indicating an overwhelming influence from seawater buffering. Lastly, batch leaching tests of the IBA/IFA mixture were performed under various mass ratios, while data were compared with those by their individuals and the theoretical leaching value, unveiling different leaching characteristics during landfill disposal. Hereby, a comprehensive characteristic metal leaching potential was achieved under various ash managements. It provides insights into environmental risks relevant to their current practices.

通过适当的浸出测试，可以定量定义与城市固体废物焚化（MSWI）灰相关的健康危害，即焚化底灰（IBA）和焚烧飞灰（IFA）。但是，必须结合特定的环境方案得出正确的结论。本文通过实验室浸出研究模拟了基于MSWI灰当前管理的几种环境压力，以了解其影响。首先研究了散装金属回收对IBA浸出潜力的影响，表明某些金属（包括相对较高含量（> 1000 mg / kg）的金属，如钡，铜，铅和锌）的促进释放。还模拟了海水的影响。随着新化学的建立，大多数金属的释放发生了改变。进一步在盐和酸性环境下进行了分批浸出试验，以了解它们的聚集效应，表明海水缓冲作用产生了压倒性的影响。最后，对IBA / IFA混合物进行了不同质量比的分批浸出测试，同时将数据与他们的个人数据和理论浸出值进行了比较，揭示了垃圾填埋场处置过程中的不同浸出特性。由此，在各种灰分管理下获得了综合的特征性金属浸出潜力。它提供了与当前实践有关的环境风险的见解。在各种质量比下对IBA / IFA混合物进行分批浸出测试，同时将数据与他们的个人数据和理论浸出值进行比较，揭示了垃圾填埋场处置过程中的不同浸出特性。由此，在各种灰分管理下获得了综合的特征性金属浸出潜力。它提供了与当前实践有关的环境风险的见解。在各种质量比下对IBA / IFA混合物进行分批浸出测试，同时将数据与他们的个人数据和理论浸出值进行比较，揭示了垃圾填埋场处置过程中的不同浸出特性。由此，在各种灰分管理下获得了综合的特征性金属浸出潜力。它提供了与当前实践有关的环境风险的见解。
