Abstract: Inductively coupled plasma-mass spectrometry (ICP-MS) was used for the qualitative and quantitative analysis of metals in samples of mud from Xinjiang Wusu Tianshan volcano.ICP-MS analysis results showed that for the volcanic mud without any treatment,K mass fraction is 1.7%;Na mass fraction is 1.5%;total alkali metal mass fraction is more than 3.2%;Mg mass fraction is 0.9%;Ca mass fraction is 0.4%;and total alkaline earth metal mass fraction is more than 1.3%.The overall results indicate that the untreated volcanic mud is rather highly alkaline,irritant and corrosive;Hg and Pb mass fraction meet national health standards requirements;but mass fraction of As is slightly higher than national health standards.The results also showed that the total mass fraction of Zn,Mn and Cu is in line with the provisions of Safety and Technical Standards for Cosmetics (2015 ed),which is below 1% according to the national standards.In accordance with Safety and Technical Standards for Cosmetics (2015 ed),Cr and Cd are not allowed while the analysis results showed that Cr mass fraction is 69.14 μg/g,and Cd mass fraction is 0.28 μg/g.Overall microbial colony detection results showed that there are no fecal coliforms,Pseudomonas aeruginosa and Staphylococcus aureus in the sample and the total content of mold and yeast are not over than the provisions in the national standard.However,total number of colonies exceeds the provision in Safety and Technical Standards for Cosmetics (2015 ed).
