帮我翻译下列语段：近年来随着医药抗生素滥用和畜牧业、水产养殖业的快速扩张我国成为了抗生素使用大国。这种过量使用抗生素导致了残留抗生素的大量积聚最终在河流汇集到河口近岸区域。这些残留抗生素威胁到整个人类及大环境因为它们导致了很多耐药菌的出现。这些耐药菌是对人体健康的严重威胁因此研究抗生素在河口近岸区域的迁移转化行为变得非常必要。

In recent years, with the overuse of antibiotics in medicine and the rapid expansion of animal husbandry and aquaculture, China has become a major user of antibiotics. This excessive use of antibiotics has led to a large accumulation of residual antibiotics, which ultimately converge in the estuarine areas of rivers. These residual antibiotics pose a threat to both humanity and the environment because they contribute to the emergence of many drug-resistant bacteria. These drug-resistant bacteria are a serious threat to human health. Therefore, it is necessary to study the migration and transformation behavior of antibiotics in the estuarine areas.
