Hydroxyl apatite (HA) is a porous structure substance and having high adsorption capacity, so it is widely used in biomedicine. N-doped TiO2 is a photocatalytic activity and this material is capable of working in visible light. The combination of HA and N -TiO2 has created HA/N-TiO2 material that is both adsorbent and redox. The structural char...

Contamination status of 16 polycyclic aromatic hydrocarbons (PAHs) were examined in settled dust samples collected from working (ELV-W) and living (ELV-L) areas of end-of-life vehicle processing workshops and from urban houses (U-H) in northern Vietnam. Levels of 16 PAHs in the ELV-W samples ranged from 1200 to 3600 (median 3100) ng/g, which wer...
