Question 1

Which of the following is believed to be the single most important environmental threat to the health of American children who may be exposed to it?

Accepted Answer

Lead is considered the single most important environmental threat to the health of American children, primarily due to its potential to cause developmental issues and cognitive impairments when children are exposed to it, especially in old paint and contaminated dust.

Question 2

Infants born to Yusho and Yu-cheng mothers were small at birth and had dark discoloration of the skin that faded after a few months, leading to what nickname?

Accepted Answer

The infants were referred to as "Coca-Cola babies" due to the dark discoloration of their skin, which was a symptom of the exposure to toxic compounds from the Yusho and Yu-cheng incidents.

Question 3

Which of the following was the first environmentally caused cancer to be recognized from an occupational exposure that was common in 19^th century English chimney sweeps?

Accepted Answer

Scrotal cancer was the first recognized occupational cancer, identified in the 18th century among English chimney sweeps due to their prolonged exposure to soot.

Question 4

Because people live together in cities and suburbs, they do not have to rely on other to provide their food and water and to dispose of their wastes.

Accepted Answer

People living in cities and suburbs still rely on others to provide essential services such as food and water supply and waste disposal, as these are typically managed by different organizations or municipal services.

Question 5

Environmental health is clearly the responsibility of the government.

Accepted Answer

Environmental health involves controlling or mitigating factors in the environment that can potentially harm human health, which is a public concern requiring regulation, monitoring, and intervention strategies that typically fall within the purview of government agencies at various levels (local, state, national, and international).

Question 6

Today, medical and dental x-rays constitute the largest source of non-background radiation exposure.

Accepted Answer

Medical and dental x-rays are indeed the largest source of man-made, non-background radiation exposure to the general population, primarily because these procedures are widespread and routinely used in healthcare for diagnostic purposes.

Question 7

The use of DDT was banned in the United States in 1972.

Accepted Answer

The use of DDT (Dichloro-Diphenyl-Trichloroethane), a synthetic insecticide, was banned in the United States in 1972 due to its harmful environmental effects, particularly its detrimental impact on wildlife, as well as concerns about human health risks.

Question 8

General Electric plants were found in 1975 to have contaminated the Hudson River with precursors of DDT.

Accepted Answer

General Electric plants were found to have contaminated the Hudson River with polychlorinated biphenyls (PCBs), not precursors of DDT.

Question 9

The most widespread chemical contaminants in the world are PCBs, which can be used in the production of sealed electrical components.

Accepted Answer

PCBs (Polychlorinated Biphenyls) are indeed among the most widespread chemical contaminants found globally, and they have been used in various applications including the production of sealed electrical components such as transformers and capacitors due to their insulating properties.

Question 10

Animal waste from factory farms are collected in lagoons for separation of liquid components.

Accepted Answer

Animal waste from factory farms is often collected in lagoons, where the liquid and solid components separate naturally due to the settling process. This method is used to manage and treat the waste before further processing or land application.

Question 11

When heavy rains strike areas with CAFOs, the manure in lagoons may be washed out into lakes and rivers, causing serious problems.

Accepted Answer

CAFOs (Concentrated Animal Feeding Operations) store animal waste in large lagoons, and heavy rains can cause these lagoons to overflow, leading to the discharge of manure into nearby water bodies. This can result in water pollution and harm aquatic ecosystems.
