1. Estimate the total lifetime average daily chronic daily intake of benzene from exposure to a city water supply that contains benzene concentration equal to the drinking water standard (0.005 mg/L). Assume the individual is an adult male who consumes 2.3 L/d of the city water for 63 years, has a body weight of 78 kg, and a life expectancy of 75 years. The individual is also exposed to benzene in the shower. Suppose the average air concentration is 5 µg/m³, with an ingestion rate of 0.833 m³/h. Assume that he takes one shower a day that lasts 30 minutes. In addition, determine the cancerous risk.
