珠江口海域有八大口门(虎门、蕉门、洪奇沥、横门、磨刀门、鸡啼门、虎跳门和崖门)的河水入海。在研究珠江口海域水体中镉的存在形态及其迁移变化规律时,很有必要追根求源,了解各入海口门河水中镉形态的分布状况,从中找出一些规律性的东西,这对弄清珠江口海域水体中镉的迁移转化规律具有一定的意义。因此,我们采集了七大口门的入海口及珠江口海域的水样进行分析研究。从调查分析结果发现,七大口门水体中镉的五种存在形态与珠江口海域水体中的镉形态具有相当明显的依存关系,从中可以看到七大口门镉的污染物分布状况及其进入珠江口海域后镉的环境化学变化规律。
The Pearl River estuary area has eight gates (Humen, banana, Hongqi Lek, Wang Men, Modao Men, Jittit door, tiger jump door and Yamen) into the sea. In the study of the Pearl River estuary in the presence of cadmium in water bodies and their migration patterns of change, it is necessary to search for sources to understand the various rivers into the estuary of cadmium water distribution, from which to find some regularity, which pairs The migration and transformation of cadmium in the water of the Pearl River Estuary is of some significance. Therefore, we collected and analyzed the water samples from the estuary and the estuary of the Pearl River estuary at the seven major gates. According to the investigation and analysis, it is found that the five existing forms of cadmium in the waters of the Qiandurekou have a quite obvious dependence on the cadmium forms in the water bodies of the Pearl River estuary. From this, we can see the distribution of pollutants of cadmium in the waters of the Qianduomen and their entry into the Pearl River Environmental chemical changes of cadmium in the mouth area.
