摘要
四环素类抗生素由于其抗菌效率高、应用范围广、价格低廉等特点,被广泛应用于临床医学、畜牧业和养殖业等领域。特别是超量使用以及不当处理,使其在水体、土壤和大气等环境介质中残留、富集并发生迁移转化,进而污染环境,危及生态系统甚至人类健康。因此,了解其在环境中的检出水平以及污染扩散情况尤为重要。虽然这类抗生素在污染介质中的检出水平多为痕量,但在不同的介质中检出频率较高。四环素类抗生素在各种环境介质中的污染扩散均表现出迁移率高、扩散易发生且范围广等特点。文章对不同介质中抗生素的痕量检测、多污染物的复合污染以及抗生素的抗药性等方面的研究进行了展望。
Tetracycline antibiotics are widely used in clinical medicine,animal husbandry,and breeding industry due to high antibacterial efficiency,wide application range and low price.However,the abuse and improper treatment of tetracycline antibiotics have led to unintended adverse results.The residual concentration of tetracycline antibiotics is above the safety level due to accumulation in the media.The enrichment,migration and transformation of tetracycline residues in the environmental media such as water,soil,and atmosphere have posed a huge threat to the health of both ecosystem and human.Therefore,it is important to understand the residual concentration and spreading of tetracycline antibiotics in the environment.Although the levels are generally trace,it is frequently existed in different media.Furthermore,the pollution diffusion of tetracycline antibiotics in all environmental media has the characteristics of high mobility,easy diffusion and wide ranges.The future research should focus on trace detection of antibiotics in different media,combined pollution of multi pollutants and antibiotic resistance.
