Household inhalants exposure and nasopharyngeal carcinoma ...- mosquito coil making that can be performed in school laboratory tests are likely ,Dec 29, 2015·Epidemiological studies show that cigarette smoking increase the risk of nasopharyngeal carcinoma (NPC), however, whether other common, potentially adverse household inhalants increase NPC risk remains uncertain. We conducted a large case-control study to explore the effects of household inhalants, such as incense, mosquito coil, cooking fumes, and wood combustion, on NPC risk.The Use Of Smoke As A Mosquito Repellent - Medicinal PlantsSep 26, 2021·The Use Of Smoke As A Mosquito Repellent. Smoke is the most widely used means of repelling mosquitoes utilised in the rural Tropics. Waste plant materials are frequently burned in Sri Lanka as a mosquito repellent, even though indoor residual spraying has been carried out by the government for many years (Silva, 1991).
