Exposure to Total Volatile Organic Compounds (TVOCs) from Household Spray Products
Keywords:Household products, exposure, Total volatile organic compounds, hazard ratio, indoor environment
Emission of volatile organic compounds from the use of household spray products has a negative impact on health and environment. Total Volatile Organic Compounds (TVOCs) concentration levels emitted from forty –five registered consumer spray products in Nigeria were measured using MultiRAE TVOCs gas monitor. Human exposure to emitted TVOCs through inhalation, ingestion or through dermal route was evaluated using the ConsExpo spray model. The average TVOCs emission from all the investigated samples was in the range of 1664 and 560994.7 µg m-3 with an average of 63632.2 µg m-3. Generally for all the samples considered, the average released concentrations, inhaled dose, dermal doses, and average deposition rates were in the ranges of 1.83E+04 – 1.00E+06 µg m-3; 1.47E+03 – 8.01E+04 µg ; 3.41E+04 – 4.84E+05 µg; and 1.79E+01 – 1.01E+03 µg s-1, respectively. The results provide information that could be used to significantly improve human exposure and risk assessment to emitted aerosols from spray products.
