Question
Chapter 10, Problem 3TYC
To determine
The region of exposure to lead, asbestos, radon, and PBDEs.
Expert Solution & Answer
Answer to Problem 3TYC
The harmful chemical compounds such as lead, asbestos, radon, and PBDEs are indoor hazards that cause detrimental effects on human health.
Explanation of Solution
Toxicity is defined as the degree at which a chemical substance harms humans and animals. Toxic substance occurs either naturally in nature or is synthesized artificially in laboratories. It causes adverse effects on human health and disrupts various physiological and physical functions of cell.
The region of exposure to harmful chemicals is described as below:
Radon is a radioactive gas which is released from cigarette smoke and is one of the most harmful indoor hazards that causes lung cancer.
Asbestos are chemicals that are used as insulation in walls and other products and affect the health when inhaled.
Lead poisoning is caused from water pipes or lead paints that are used to paint walls. It causes serious cognitive problems, behavioral abnormalities, damage to vital organs and leads to death.
PBDEs are polybrominated diphenyl ethers. They are used as fire retardants in computers, televisions, plastics, and furniture. These compounds evaporate at very slow rate and act as endocrine disruptors. It also causes cancer.

Background/Synopsis
You are working for the administrative or government apparatus of a city. Good credentials have
resulted in you working in this position.
The top echelon of the city government changed a few years ago, but they did not replace many
staff. Nonetheless, the situation is such that the city is led by a corrupt mayor who has realized dded
that elections are approaching. Opinion polls suggest that a significant part of the electorate has
the environment as a major concern. Close associates of the mayor organized a focus group and
chose to investigate several initiatives which they felt might be possible to conduct in a relatively
short amount of time.
Jual pro
Metho
The administration wants several projects examined. You have been tasked with conducting a
cost benefit analysis on the construction of permeable pavements. The idea put forth is to replace
A2_Call city alleyways with permeable pavements as a means to better manage water resources.

I always find it interesting to consider the Earth's Hydrologic Cycle, our water in all of the different phases: solid ice, liquid water, and water vapor (a gas). In place number one for the majority of the World's water, we have the oceans. In place number two, we have ice. Neither one is available to us for drinking water at this point. Amazingly enough, in place number three is groundwater before lakes and streams. Water has led to many problems in the history of California, the United States, and even the world.

Outline of topic: Increased urbanization together with climate changes forces cities to find solutions for their simultaneous water shortage and flooding problems. The preservation of water resources needs sustainable urban water management strategies that combine ecological health maintenance with these priorities. This study investigates combined strategies that involve rainwater collection together with wastewater treatment and the deployment of green infrastructure consisting of urban wetlands alongside permeable pavements. The research aims to discover multi-purpose solutions that decrease flood dangers together with water shortages while maintaining ecological health for long-term urban water management success. The research investigates ways in which novel solutions assist cities to create…arrow_forward

Notice in Figure 8.1 that more water evaporates from the oceans than is returned directly by precipitation. If sea level is not dropping, identify a source of water for the oceans in addition to precipitation. 4. Worldwide, about how much of the precipitation that falls on the land becomes runoff: 35, 55, or 75 percent? 5.
