摘　　要：水体沉积物中的酸挥发性硫化物(AVS)对于沉积物环境质量,尤其是对于沉积物结合重金属生物有效性的影响,近年来已越来越受到研究者的广泛关注。本文评述了此领域的主要研究进展,包括沉积物中 AVS 的来源和含量、采样和分析技术及其对沉积物环境质量的影响,并对此领域的进一步研究提出了展望。As a reactive pool of solid-phase sulfide that is available to bind metals and render that portion unavailable and nontoxic to biota,acid volatile sulfide(AVS)in aquatic sediments has received more attention recently.The retrospect and prospect on this field were reviewed and criticized in this paper,including:1)the origin of AVS in sediments;2)the sampling techniques and analysis methods of AVS and 3)the toxicity of AVS in sediments and its ef- fect on the bioavailability of sediment-bound heavy metals.The main problems and further studies were also suggested.
