In order to research the contents and risks of heavy metals in commercial fertilizers commonly used in agricultural fields in Fujian province，the samples of commercial fertilizers commonly used in agricultural fields in Fujian province were collected，and the contents of eleven heavy metals (Cd，Hg，As，Pb，Cr，Tl，Ni，Co，V，Cu and Zn) were determined by inductively coupled plasma mass spectrometry (ICP-MS) and atomic fluorescence spectrometry (AFS). The heavy metal contents in different commercial fertilizers were analyzed and evaluated according to national standard limits. The results showed that Tl and Co were not detected in nitrogen fertilizers，while other nine heavy metals were detected in nitrogen fertilizers and eleven heavy metals were detected in other fertilizers. The heavy metal contents in different commercial fertilizers varied considerably，with Tl and Cr showing moderate variation and all other heavy metals showing strong variation. The contents of heavy metals in phosphate fertilizer，organic fertilizer and organic-inorganic compound fertilizer were relatively higher. The As content in 40% of the samples of organic-inorganic compound fertilizers exceeded the limit values specified in the Limitation requirements of toxic and harmful substance in fertilizers (GB 38400—2019)，while the contents of other heavy metals in organic-inorganic compound fertilizers and all heavy metals in other fertilizers were within the limit values. The contents of heavy metals in different types of fertilizers varied greatly depending on the raw materials used in their production and should be strictly controlled at source. The heavy metals in the studied fertilizers were generally at a safe level，however，the potential contamination of agricultural systems caused by heavy metals in commercial fertilizers cannot be ignored. Considering the accumulation characteristics of heavy metals，more attention should be paid to the potential contamination of Cd，Hg，As and Pb in terms of heavy metal content，fertilizer application method and duration of application.
