Along　with　the　rapid　development　of　economy　and　urbanization,　noise　and　air　pollution　are　becoming　major　occupational　health　hazards　in　the　process　of　industrial　production.　In　this　study,　we　collected　data　from　7293　industrial　workers　in　China.　The　association　between　occupational　exposure　of　noise　and　dust　and　blood　pressure　was　investigated.　Controlling　for　demographic　variables,　including　sex,　age,　and　length　of　service,　a　stepwise　regression　model　with　backward　elimination　was　constructed.　The　results　showed　that　both　noise　and　dust　decreased　the　level　of　systolic　blood　pressure　(p＜0.001).　This　finding　prompted　the　manufacturing　industry　to　reduce　noise　and　dust　hazards　and　protect　the　occupational　health　of　workers.　Prospective　studies　in　different　populations　are　still　required　to　verify　the　net　contribution　of　noise　and　dust　to　the　decrease　in　blood　pressure.
