Abstract:
Magnetic particles(MPs)are widely present in the environment,with high prevalence and complex sources.During the past decade,with the rapid development of separation techniques and detection methods for MPs,exogenous MPs have been found to be present in different parts of human body.Especially,the presence of MPs in human brain and blood has led to a high level of concern about their health risks,as the potential association with the development of neurodegenerative diseases such as Alzheimer's disease.Therefore,analysis of MPs in environmental and biological media is an important basis for understanding their physicochemical properties,investigating their biogeochemical cycling processes,and assessing their environmental and health risks.Here,the occurrence of MPs in different environmental media and biological samples were systematically summarized.The separation methods,characterization methods,qualitative and quantitative analysis methods,and source apportionment techniques of MPs were also reviewed.Finally,the future challenges in the development of analytical techniques for MPs were discussed.
