What is the difference between residual and pollutant

Having eliminated this dominated strategy, determine whether Asahi and Kirin now. At the end of 5 years, the compactor will be replaced by another identical compactor Cynthia hopes to be so lucky. Assuming that the City will own and operate a landfill f. What is the expected cost in Year 1 if the firm has projected that the machinery cost wil. Assume you work five days a week and time spent riding on a bus or driving a c. To evaluate the two projects, you decide to use the company's weighted average cost of capital WACC for the less risky project 12 percent and the WACC plus two points 1.

Suppose firm 1 has a constant marginal cost of 10 while firm 2 has a constant marginal c. A firm is planning to manufacture a new product. As the selling price is increased, the quantity that can be sold decreases. We ensure premium quality solution document along with free turntin report! Sign In Sign Up. Already have an account?

Exposure to air pollution has been associated with cancer or numerous health problems, including decrease in lung functions, neurological damage, miscarriages, birth defects and increase in respiratory symptoms. Even short-term exposure to particle pollution is associated with cardiac arrhythmia, heart attacks and premature death. Recent studies have linked air pollution and lung cancer, and it has been suggested that the efffects of air pollution on the reduction of life expectancy are not uniformly distributed, but depend on factors such as education and antioxidant vitamin status.

This implies that life expectancy could be reduced more in disadvantaged populations that are often disproportionately represented in neighborhoods near industrial sites.

EPA to promulgate and implement technology based standards on emissions of nearly hazardous air pollutants. These emission limits were to reflect the "maximum achievable control technology" MACT for categories of source and were adopted by the year The use of MACT relies on the engineering judgment about the amount of the reduction in emission.

The U. EPA establishes emission limits as a percent reduction or a concentration limit that the regulated source must achieve. This strategy worked better than the risk-based approach to implement hazardous air pollutant standards that was used between and The result of risk-based standards was inefficient and ineffective, and the U.

EPA listed only eight pollutants and regulated only seven air pollutant standards. Implementing MACT standards has resulted in a significant reduction of toxic air emissions. However, the emission reductions that have been achieved as a result of the MACT program may not be sufficient to protect the public health and the environment. An assessment of the residual risk of toxic air emissions from MACT-regulated sources is needed to determine whether further controls are needed.

For many source categories, this assessment may be challenging since it must encompass concerns of the people regularly exposed to toxic air pollutants, the data gap and the concerns in the model uncertainty, complexity of the assessment and economic concerns of the industries. It is suggested that Anaerolineaceae , Cyanobacteria , Acidobacteria , and Nitrosomonadaceae were associated with the residual pollutant removal.
