Chapter 2, Problem 4DAA
Summary Introduction
To determine: The amount of mercury released from the gold production in South America.
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.

above.
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,

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.
