About this Research Topic
There is a knowledge gap and confusion about the application of organic amendments to PTE-contaminated soils and possible PTE contaminations via organic amendments. Organic amendments can act as both a sink and a source of PTEs in soils. Therefore, the selection of materials must be done after careful evaluation. Unexpected mobilization of PTEs in contaminated soils could lead to enhanced environmental issues. Also, some contaminants like microplastics in organic amendments such as from municipal solid wastes can increase the PTE mobility. Furthermore, the addition of different organic amendments changes the geochemical properties of soils such as pH and Eh affecting the dissolution of otherwise stable PTEs in soils differently. This research topic is aiming to address the PTE immobilization and mobilization mechanisms in soils with different properties, which are driven by the different types of organic amendments. Production of engineered soil amendments from different organic feedstocks to remediate the PTE-contaminated soils and their suitability for different soil types are also in scope to be discussed under this topic.
• Organic soil amendments on behavior of PTEs in soils.
• Engineered organic soil amendments to immobilize PTEs in soils.
• Soil nutrient cycling in PTE-contaminated soils with organic amendment applications.
• Role of microplastics in PTE immobilization and mobility.
• Both reviews and research articles can be submitted.
