Chapter 2, Problem 3DAA
Summary Introduction
To determine: The region that emitted most mercury from cement production.
Introduction: Mercury is a toxic element and is naturally found in water, air, and soil. It is released in the environment through weathering of rocks, volcanic activity, and human activity. Human activity is mainly responsible for the mercury releases, especially for burning of coal in coal-fired power stations, domestic uses, waste incinerators, industries, fossil fuels, and mining of metals.

- Nonearrow_forwardEnvironmentally conscious Susan has been told that a newelectric car will only generate 6 ounces of greenhouse gases (GHG) permile, but that a standard internal combustion car is double that at 12ounces per mile. However, the nature of electric cars is such that the new technology and electric batteries generate 30,000 lbs. of GHG to manu-facture and another 10,000 lbs. to recycle. A standard car generates only 14,000 lbs. of GHG to manufacture, and recycling with established tech-nology is only 1,000 lbs. Susan is interested in taking a systems approach that considers the life-cycle impact of her decision. How many miles mustshe drive the electric car for it to be the preferable decision in terms ofreducing greenhouse gases?arrow_forwardUsing scrubbers on coal-fired power plants can remove pollutants from the emissions, but results in the accumulation of coal ash. .
