A harmful chemical named TNF has been found to be in the regional environment in Reno. Environmental scientists at the University of Nevada, Reno measured the concentrations of TNF to be 50 µg/kg in fish, 0.8 µg/m³ in air, 6.0 µg/m³ in water, and 5.0 µg/mg in settled dust. Every day, a typical Nevadan (bodyweight of 80 kg) consumes 1.5 kg of fish, inhales 15 m³ of air, drinks 0.003 m³ of water, and ingests 50 mg of settled dust. Assume such a typical Nevadan is exposed to TNF every day for 15 years. The absorption efficiency is 80% for the oral and 70% for the respiratory routes. Please find the uptake dose rate (in µg/kg/d) of Chemical TNF by a typical Navadan through all exposure pathways for these 15 years. Please round your results to the nearest integer and enter the number alone, without the unit.
