ENGR 202 FINAL REVIEW EXAM
QUESTIONS AND ANSWERS 100% PASS
Role of engineering in relationship with the environmental stewardship concept -
ANS Engineers are involved in making decisions related to technology development and its
deployment. They are part of a product's design, raw material acquisition, etc., therefore they
must know the environmental impacts of their choices.
Name two major contaminants for ground waters and their sources? - ANS 1. Petroleum
compounds (organic chemicals) - leaking from underground storage tanks
2. Nitrates from agriculture fertilizers
Name 3 activities that impact air quality - ANS 1. Diesel combustion (PM)
2. Oil and coal combustion (SO2)
3. Fossil fuel combustion (complete and incomplete, CO2 and CO respectively)
Name 3 activities that impact soil quality - ANS 1. Solid waste (paper and paperboard)
2. Hazardous waste (wastewater treatment)
3. Radioactive waste (uranium mining)
Difference between primary and secondary water quality standards? - ANS Primary (human
health): designed to protect public health
1 @COPYRIGHT 2025/2026 ALLRIGHTS RESERVED.
, Secondary (human welfare): non-enforceable guidelines related to public welfare criteria
Difference between smoke and smog? - ANS Smoke is produced by something burning,
whereas smog is a mixture of fog and smoke and is produced from the reaction between
sunlight and carbon emitted gases in the atmosphere
What are the 4 characteristics of hazardous wastes? - ANS -Ignitability: ability to burn
-Corrosivity: ability to corrode metals
-Reactivity: ability to react violently with other substances, even with water
-Toxicity: ability to threaten human health and welfare
Wavelength of IR and UV radiation - ANS UV: below 3e-6 m
IR: above 3e-6 m
Average production of solid wastes per capity/perday? - ANS 100kg/person/day
EPA - ANS Environmental Protection Agency
PM - ANS Particulate Matter
NAAQS - ANS National Ambient Air Quality Standards
IPCC - ANS International Panel on Climate Change
T_e - ANS Earth's tempterature
