PM2.5　samples　were　collected　from　three　monitoring　sites　including　Handan　Iron　&　Steel　Group　(Han　Gang),　Environmental　Monitoring　Center　in　Handan　(Huan　Bao　Ju)　and　Hebei　University　of　Engineering　(Kuang　Yuan)　in　Handan　urban　area　for　typical　months　of　four　seasons.　The　water-soluble　ions,　elements　and　carbonaceous　components　were　analyzed.　A　coupled　PM2.5　source　apportionment　approach,　combining　emission　inventory,　receptor　model　and　source-oriented　model,　was　used　to　identify　PM2.5　source　contributions　in　Handan　urban　area.　The　results　show　that　the　annual　PM2.5　concentration　in　Handan　urban　area　was　85.5µg/m3.　The　concentration　in　autumn　and　winter　was　significantly　higher　than　other　seasons.　The　PM2.5　concentration　in　Han　Gang　site　was　slightly　higher　than　that　in　other　sites.　The　components　in　PM2.5　with　higher　proportion　were　NO3　-,　SO4　2-,　POA,　SOA　and　NH4　+,　accounted　for　15.7%,　14.5%,　13.2%,　12.2%　and　12.4%　of　the　total　PM2.5　concentration,　respectively,　presenting　obvious　secondary　and　organic　pollution　characteristics.　The　proportion　of　secondary　and　organic　components　in　winter　was　slightly　higher　than　that　in　other　seasons.　The　primary　organic　aerosol　(POA)　and　secondary　organic　aerosol　(SOA)　in　Huan　Bao　Ju　site　was　slightly　higher　than　that　in　other　sites.　Metallurgy　and　dust　emission　were　the　main　sources　of　PM2.5　concentration.　The　contribution　was　27.0%　and　18.7%,　respectively.　The　contribution　ratio　of　metallurgy　in　spring　and　summer　was　higher　than　that　in　other　seasons.　The　contribution　ratio　in　Han　Gang　site　was　significantly　higher　than　other　sites.　©　2019,　Editorial　Board　of　China　Environmental　Science.　All　right　reserved.
