Legacy and emerging organic pollutants in indoor and outdoor environments in Africa: Contamination levels, health risks, and analytical techniques by Godfrey Muhwezi, Christine Kyarimpa, Ivan Gumula, Christine Betty Nagawa, Solomon Omwoma, Henry Matovu, Julius Matsiko, Silver Odongo, Douglas Sifuna, Ivan Špánik, Charles Drago Kato, Patrick Ssebugere

“…Apart from a few studies for polychlorinated biphenyls (PCBs), most studies reported hazard index (HI) values less than 1 for outdoor air and indoor dust exposure, which suggested negligible non-carcinogenic risks in children and adults. Gas Chromatography and mass spectrometry were the most frequently used analytical techniques for both air and dust probably due to their sensitivity and selectivity in detecting chemical traces at the pg m−3 and ng g−1 levels. …”
