Question
Chapter 2, Problem 1DAA
Summary Introduction
To determine: The total tons of mercury released from the regions given in the Fig. 2.12.
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 the coal-fired power stations, domestic uses, waste incinerators, industries, and mining of metals.

- Environmentally 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.

Task A: DTT was once used as a potent insecticide until its harmful effects had been discovered. It is not banned. Like methyl mercury, it bioaccumulates in organisms up the food chain. The process of DTT bioaccumulation is shown in Figure 4. In your own words describe the process of bioaccumulation of DTT. Refer to your knowledge of ecology, food chains and food webs as well as feeding level (i.e trophic level). In your description use terms you have learned such as: food chain/web, Large Eish 1,000,000 Small Fish 100,000 10,000 Zooplankton Producers 1000 producer/consumer, etc. Task B: In view of what you have learned about bioaccumulation, state why it may be healthier in some circumstance to consume vegetables and why you should decrease the amount of animals consumed from the top of the food chain.
