Text Book Environmental Law & Policy

I like OTA #102862 solve this problems 1. Compare and contrast the purpose and scope of the Federal Incecticide, Fungicide, and Rodenticide Act with the provisions of the Federal Food, Drug, and Cosmetic Act. 2. The Food Quality Protection Act of 1996 repealed the Delaney Amendment; what new provisions of law replaced or substituted for this amendment? 3. Considering the impact of OSHA, should it be considered environmental law? Justify your position. 4. On what substances does the Toxic Substance Control Act focus? Are these substances otherwise subject to regulation? Justify the apparent multiple control efforts. Are they unique to these substances?

Mass and Energy Transfer

If we approximate the atmosphere to be 79% nitrogen (N_2) by volume and 21% oxygen (O_2), estimate the density of air (kg/m^3) at STP conditions (0 degrees C, 1 atm)

A lake with constant volume 10X10^6 m^3 is fed by a pollution-free stream

A lake with constant volume 10X10^6 m^3 is fed by a pollution-free stream with flow rate 50 m^3/s. A factory dumps 5m^3/s of a nonconservative waste with concentration 100 mg/L into the lake. The pollution has a reaction rate coefficient K of 0.25/day. Assuming the pollution is well mixed in the lake, find the steady-state concentration of pollution in the lake.

A lagoon is to be designed to accommodate an input flow of 0.10 m^3/s of nonconservative pollutant with concentration 30.0mg/L

A lagoon is to be designed to accommodate an input flow of 0.10 m^3/s of nonconservative pollutant with concentration 30.0mg/L and reaction rate 0.20/day. The effluent from the lagoon must have pollutant concentration of less than 10.0mg/L. Assuming complete mixing, how large must the lagoon be?

A lagoon with volume 1200 m^3

A lagoon with volume 1200 m^3 has been receiving a steady flow of a conservative waste at a rate of 100m^3/day for a long enough time to assume that steady-state conditions apply. The waste entering the lagoon has a concentration of 10mg/L. Assuming completely mixed conditions, a) what would be the concentration of pollutant in the effluent leaving the lagoon? b) If the input waste concentration suddenly increased to 100mg/L, what would the concentration in the effluent be 7 days later? 2. repeat problem 1 for a nonconservative pollutant with reaction rate K = 0.20/d
