| 中文摘要 |
| 微塑料(MPs)在土壤中广泛存在,其潜在生态风险已经引起了全球的关注. 微塑料能够与土壤中的镉(Cd)发生相互作用,为生态系统安全和人体健康带来新的风险. 文献计量学统计结果显示,土壤微塑料与Cd复合污染研究是当前的研究热点,尚处于起步阶段. 系统梳理了国内外关于土壤微塑料和Cd复合污染的研究现状,阐述了微塑料和Cd在土壤中的相互作用和对Cd生物有效性的影响,以及复合污染的生态危害和健康效应. 结果表明,微塑料含Cd添加剂的浸出、微塑料对Cd的吸附与解吸是影响土壤Cd分布以及生物有效性的重要因素,过程主要受到微塑料的结构与性质(如:种类、粒径和老化程度等)、丰度、土壤理化性质(如:pH、温度、电导率等)和暴露时间等影响. 微塑料能够影响Cd在生物体内的累积,改变Cd的毒性效应,为生态系统安全和人体健康带来较大的负面影响. 阐明了围绕微塑料与Cd复合污染开展进一步研究的必要性,指出仍需深入探究微塑料-Cd相互作用过程中的动态平衡机制,系统考察多因素交互作用下复合污染的生态健康效应,以及加强对自然条件下复合污染生态效应、健康风险以及修复技术的研究,研究可为农田土壤微塑料和重金属污染的生态风险评估和管控提供重要参考. |
| 英文摘要 |
| Microplastics are widespread in soils, and their potential ecological risks have attracted global attention. The interactions between microplastics and Cd in soil may pose new risks to ecosystem safety and human health. Bibliometric statistical results show that the research on microplastics and Cd combined pollution is one of the current research hotspots and is still in its infancy. This study systematically reviews the current research status of microplastics and Cd combined pollution worldwide and outlines the interactions between microplastics and Cd in soil and their effects on the bioavailability of Cd, as well as the ecological hazards and health effects. The results showed that the cadmium-based additives leached from microplastics and the adsorption/desorption of Cd by microplastics were the main factors influencing the distribution and bioavailability of Cd ions in soil. The impacts were determined by the structure and properties of the microplastics (such as type, particle size, and aging process), the physicochemical properties of soil (such as pH, temperature, and conductivity), and the duration and dose of exposure. In general, microplastics could affect Cd accumulation in organisms, change the toxic effects of Cd, and lead to more harmful effects on ecosystem safety and human health. This study highlights the necessity of further research on the combined pollution of microplastics and Cd, emphasizing the need to ① investigate the dynamic equilibrium mechanisms in their interactions; ② systematically examine the ecological and health effects under multifactorial conditions; and ③ explore the ecological impacts, health risks, and underlying mechanisms in natural environments. These studies will provide important references for the ecological risk assessment and management of microplastics and heavy metal combined pollution in agricultural soils. |
