随着纳米材料的广泛应用,从原料开采、加工生产到使用损耗,都会造成纳米颗粒在环境中的释放,大量纳米颗粒进入水环境,最终沉降于环境水体中。纳米颗粒与环境中的化学污染物相互混合,使纳米颗粒和重金属的共暴露成为可能。由于环境中的化学物质存在着复杂的交互作用,尤其在医学领域,纳米二氧化钛(nano-Ti O2)的毒性作用日益受到广泛关注。nano-Ti O2与环境中化学物质共同暴露的安全性和影响评价十分必要。简要综述了nano-Ti O2材料与环境中化学物质的交互毒性作用。
With the extensive application of nanomaterials, from the raw material mining, processing and production to the use of loss, will cause the release of nanoparticles in the environment, a large number of nanoparticles into the water environment, and ultimately settled in the environment of water. The mixing of nanoparticles with chemical contaminants in the environment makes it possible to co-expose nanoparticles and heavy metals. Due to the complex interactions of chemicals in the environment, especially in the medical field, the toxic effects of nano-Ti O2 are gaining more and more attention. It is necessary to evaluate the safety and impact of nano-Ti O2 in co-exposure with chemicals in the environment. The interactive toxic effects of nano-Ti O2 materials and chemicals in the environment are briefly reviewed.
