Environmental　magnetism　parameters　have　become　a　useful　tool　in　addressing　environmental　issues.　Due　to　the　rapid,　sensitive,　economical　and　non-destructive　characteristics　of　environmental　magnetism,　the　present　contribution　focuses　on　magnetism　parameters　as　proxy　for　heavy　metal　pollution,　especially　from　their　relationship　with　contents　of　heavy　metal.　We　evaluated　heavy　metals　pollution　and　examined　environmental　magnetism　in　the　Dexing　section　of　the　Le＇an　River.　The　pollution　load　index　(PLI)　of　Cr,　Pb,　As,　Cu　and　Zn,　as　well　as　the　concentration　of　other　heavy　metals,　were　analyzed,　and　the　magnetic　indexes　of　various　sediments　were　analyzed.　The　results　showed　that　the　concentrations　of　all　heavy　metals　far　exceeded　the　local　background　values,　and　that　the　average　contamination　factor　of　Cu　was　as　high　as　22.88,　making　it　the　element　of　most　serious　contamination.　The　problem　of　heavy　metal　pollution　near　the　mine　is　very　serious.　The　content　of　magnetic　minerals　in　sediments　of　Le＇an　River　is　relatively　high　and　the　composition　of　magnetic　minerals　is　relatively　stable.　The　stable-single　domin　(SSD)　content　is　high　at　S1　and　S10,　indicating　that　ferromagnetic　mineral　content　is　relatively　rich　here,　which　dominates　the　magnetic　characteristics　of　the　sample.　In　general,　it　was　found　that　environmental　magnetism　indicators　did　not　exist　in　the　Dexing　section　of　the　Le＇an　River　that　could　clearly　indicate　the　concentration　of　heavy　metal　pollution.　Only　a　few　heavy　metals　can　be　effectively　indicated　by　magnetic　parameters.　IRM-20mT　and　S-ratio　can　be　used　as　indicators　of　Cr,　Pb,　As,　Cu　and　Zn,　but　they　are　not　accurate.　The　correlation　between　Sr　and　magnetic　indexes　IRM200mT,　IRM300mT,　SIRM,　IRM-300mT　and　HIRM　is　significant,　which　can　be　used　as　an　indicator　of　Sr　concentration.　IRM20mT　can　also　be　used　as　an　indicator　of　Hg　concentration.
