or situation but not necessarily affected.
a) True
b) False
View Answer
Answer: b
Explanation: Vulnerability is the state where a person can be influenced by
situation but not necessarily affected. Exposure indicates contact with the
contaminant.

increase the incidence of adverse health effect.
a) Hazard identification
b) Exposure assessment

d) Estimation of risk
View Answer
Answer: d
Explanation: Estimation of risk is done at risk characterization whereas land use,
contaminant level, affected population and biota data play a major role while
identifying a hazard.
8. Hazard is defined as the probability of suffering harm or loss.
a) True
b) False
View Answer
Answer: b
Explanation: Risk is the probability of suffering harm whereas hazard is a
potential source of harm.
9. Why does site history have to be considered for hazard identification?
a) To estimate the risk
b) To calculate carcinogenic exposure
c) To know the probable source and causes of contamination on site
d) For determination of remedial actions
View Answer
Answer: c
Explanation: Site history provides precise information about the activities that had
been carried on the area. Most of the instance contamination is due to past
activities on site.
10. What is the main objective of risk assessment?
a) To evaluate hazard and minimize the risks
b) Remediation of contaminated sites
c) Hazard management
d) To know source of pollutants
View Answer
Answer: a
Explanation: Risk assessment helps to understand possible problems and
provides alternatives as well as control measures to reduce the accident.
11. What is the first stage of risk assessment?
a) Exposure assessment

5. b) Hazard identification
c) Toxicity study
d) Risk characterization
View Answer
Answer: b
Explanation: Hazard identification is the first stage of risk assessment. It provides
clear understanding about chemical contaminants, their concentration and
distribution in environment.

a) Stressor has the potential to cause harm to humans and ecological systems
b) Poses threat to surrounding
c) Monitoring is failed
d) Outburst of chemicals
View Answer
Answer: a
Explanation: An incident is called hazardous only when the contaminant poses
threat to humans and ecological systems which may results in catastrophic.
13. The purpose of risk management is to identify potential problems before they
occur so that risk-handling activities may be planned.
a) False
b) True
View Answer
