PAHs are generated through incomplete combustion of organic matter and automobile exhaust, resulting in high concentrations in road dust samples. In general, PAHs in the environment can be classified into two main groups: petrogenic and pyrogenic. Some PAHs are carcinogens and mutagens. PAHs pollution including the human health risks has been monitored widely in the Asian countries. This study focused on environmental pollutants, such as polycyclic\naromatic hydrocarbons (PAHs) in Mandalay, the economic center of Upper Myanmar. Samples (RD-1 to RD-9) were collected from nine different sites in Mandalay. The concentration of PAHs in road dusts was detected by using gas chromatography mass spectrometry (GC-MS). The results showed that high concentrations of PAHs were detected in road dust. The highest concentration of PAHs was found in 1200.67 ng/g dry wt. in RD 5 followed by the second highest concentration, 814.88 ng/g dry wt. in RD 1 and the third highest concentration, 707.37 ng/g dry wt. in RD 3. PAHs such as Fluoranthene,\npyrene, chrysene, phenanthrene, and coronene are predominant in road dust from Mandalay. PAH diagnostic ratios suggested that fossil-fuel vehicular exhausts and biomass combustion are major PAH sources in road dust in Mandalay.\""}]},"item_1583103108160":{"attribute_name":"Keywords","attribute_value_mlt":[{"interim":"Polycyclic Aromatic Hydrocarbons"},{"interim":"Road dusts"},{"interim":"Diagnostic ratios"}]},"item_1583103120197":{"attribute_name":"Files","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2025-06-12"}],"displaytype":"preview","filename":"Concentration, Distribution, Source Analysis, and Potential Risk.pdf","filesize":[{"value":"355 KB"}],"format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://meral.edu.mm/record/11082/files/Concentration, Distribution, Source Analysis, and Potential Risk.pdf"},"version_id":"7771abed-edc0-4b5b-b38a-065538ba6f65"}]},"item_1583103131163":{"attribute_name":"Journal articles","attribute_value_mlt":[{"subitem_journal_title":"Naypyitaw State Academy Research Journal","subitem_pages":"68-78","subitem_volume":"1"}]},"item_1583105942107":{"attribute_name":"Authors","attribute_value_mlt":[{"subitem_authors":[{"subitem_authors_fullname":"Ei Ei Mon"},{"subitem_authors_fullname":"Haruhiko Nakata"}]}]},"item_1583108359239":{"attribute_name":"Upload type","attribute_value_mlt":[{"interim":"Publication"}]},"item_1583108428133":{"attribute_name":"Publication type","attribute_value_mlt":[{"interim":"Journal article"}]},"item_1583159729339":{"attribute_name":"Publication date","attribute_value":"2025-05-01"},"item_title":"\"Concentration, Distribution, Source Analysis, and Potential Risk Assessment of Polycyclic Aromatic Hydrocarbons in Road Dusts from Mandalay, Myanmar\"","item_type_id":"21","owner":"233","path":["1704332335426","1704445744183"],"publish_date":"2025-06-12","publish_status":"0","recid":"11082","relation_version_is_last":true,"title":["\"Concentration, Distribution, Source Analysis, and Potential Risk Assessment of Polycyclic Aromatic Hydrocarbons in Road Dusts from Mandalay, Myanmar\""],"weko_creator_id":"233","weko_shared_id":-1},"updated":"2025-06-13T03:43:54.450740+00:00"}
