Martin Kraus,Dmitrij Walter,Andreas Michalowski,Jens Königsource of concern to researchers. The current conventional methods of wastewater treatment plants are considered not efficient enough in the complete removal of the recalcitrant contaminants from water.

metal pollution in global rivers and lakes. This study reviewed past sampling data across six continents from 1970 to 2018 and analyzed the trends and sources of 10 heavy metal species in sediments from 289 rivers and 133 lakes. Collectively, river sediments showed increasing trends in Cd, Cr, Ni,用不完 发表于 2025-3-24 13:14:58

However, its easy accessibility and low cost have led to global misuse. Basically, the production of the plastics from different chemical agents is very easy but unfortunately difficult to reuse or recycle, and it is thrown away as litter, incinerated or disposedCURB 发表于 2025-3-24 19:08:11

ich does not require extracting any sample of the material to be measured. It is therefore of interest for the study of moisture content in materials, and also in the field of biomedical applications. The material one wishes to measure is placed on a flat metallic flange which terminates the wavegui
