Preview Questions Environmental Engineer | Role Specific Skill

Question 1: What is the main advantage of using a wet scrubber for controlling sulfur dioxide (SO2) emissions?

Which action should you take?

Choose only one option

It reduces the temperature of the exhaust gases

It effectively removes SO2 by absorption in an aqueous solution

It captures VOCs and other organic pollutants

It filters out particulate matter from the exhaust gases

Question 2: What is the main advantage of using Fourier-transform infrared (FTIR) spectroscopy in air quality monitoring?

Which action should you take?

Choose only one option

It can detect a wide range of gas-phase compounds simultaneously

It provides real-time measurements of particulate matter

It requires less sample preparation

It is effective in monitoring air temperature and pressure

Question 3: How do you calculate the necessary chemical dose for coagulation-flocculation treatment in a wastewater system?

Which action should you take?

Choose only one option

Ignore water quality and base the dosage on cost-effectiveness

Perform jar tests to determine the optimal dose based on water quality parameters like turbidity and suspended solids

Use the same dosage for all types of wastewater

Use a basic estimation based on flow rate

Question 4: What type of monitoring data would be most relevant for assessing the impact of wastewater discharge from a chemical plant?

Which action should you take?

Choose only one option

Volatile organic compounds (VOCs) in water

Chemical oxygen demand (COD) and biochemical oxygen demand (BOD)

Temperature and pH levels

Wastewater flow rate only

Question 5: What is the purpose of an environmental impact assessment (EIA) in ensuring legislative compliance for a new chemical plant?

Which action should you take?

Choose only one option

To assess only the facility's energy efficiency

To monitor only air pollution from the plant

To assess the aesthetic impact of the plant on local communities

To evaluate the potential environmental impacts of the proposed facility, ensuring compliance with relevant environmental regulations and mitigation measures

Question 6: When managing hazardous waste in a chemical plant, what key aspects should be considered to ensure compliance with environmental regulations?

Which action should you take?

Choose only one option

Ignoring waste handling procedures if they comply with local city laws

Properly classifying, labeling, storing, and disposing of hazardous waste according to RCRA guidelines

Focusing only on the volume of waste produced

Sending hazardous waste to the nearest landfill without treatment
