Incense has been used since ancient times to produce pleasant fragrances or to mask odors, and incense burning has been incorporated in many religious ceremonies and practices. Burning of Arabian incense (bakhour) is common in Arabian households and places of worship, often in confined, poorly ventilated places. Incense emissions are an important source of indoor air pollution that may be associated with respiratory disorders or increased risk of cancer. Particulate matter (PM), generated during combustion processes and occurring in fine and ultrafine size fractions, is a common component of indoor air.
