摘要

综述了有机和生物炭对持久性有机污染物（POPs）污染土壤的修复机制和技术的研究进展。本文讨论了持久性有机污染物在土壤中的降解、迁移和生物利用度的实际意义。最近的发现有机（和碳）改剂的应用导致土壤pH值、有机质和可溶性有机碳水平的变化，这可能使持久性有机污染物从固体相转变为水相，增加了它们对微生物分解的有效性。生物炭除了具有高表面积和优异的吸附特性（π -π相互作用）外，还可作为降解持久性有机污染物的微生物的电子供体、受体或穿梭体（通过不同的生物或化学反应）。大量有机肥料，如堆肥、生物固体、城市固体废物和生物炭改良剂被用作土壤调理剂，以增强土壤健康和作物生产力，同时也是碳和营养物质的来源，这也会影响土壤中持久性有机污染物的相互作用。

Role of Organic and Biochar Amendments on Enhanced Bioremediation of Soils Contaminated with Persistent Organic Pollutants (POPs)

Purpose of Review

This review provides a comprehensive understanding about the mechanisms and technologies for the enhanced remediation of persistent organic pollutants (POPs)-contaminated soils by organic and biochar amendments. This article discusses the practical implications in relation to degradation, mobility, and bioavailability of POPs in soils.

Recent Findings

The application of organic (and carbonaceous) amendment lead to changes in soil’s pH, OM, and soluble organic carbon levels which might shift POPs from solid to aqueous phases, increasing their availability for microbial breakdown. Biochar can be useful as an electron donor, acceptor, or shuttle for microorganisms that degrade POPs (via different biological or chemical reactions) apart from its high surface area and excellent sorption properties (π–π interactions).

Summary

Large amounts of organic such as composted manure, biosolids, municipal solid waste, and biochar amendments are utilized as a soil conditioner to enhance soil health and crop productivity as well as a source of carbon and nutrients, which can also impact the interactions of POPs in soil.
