Preview Questions Environmental Engineer | Role Specific Skill

Question 1: When conducting an EIA, which environmental factor should be considered when evaluating the effect of noise from a petrochemical facility?

Which action should you take?

Choose only one option

Heat emissions from nearby processes

Local noise standards and regulations

Visual impact on surrounding communities

Plant operating costs and their financial impact

Question 2: Under the Resource Conservation and Recovery Act (RCRA), what is required when a chemical plant generates hazardous waste?

Which action should you take?

Choose only one option

Waste must be sent to the nearest incineration facility

Waste must be discarded immediately, regardless of treatment

Waste can be stored indefinitely without record keeping

The plant must classify, label, track, and dispose of hazardous waste in compliance with RCRA standards

Question 3: What is the role of air toxics monitoring in a petrochemical plant's air quality management plan?

Which action should you take?

Choose only one option

Air toxics monitoring measures hazardous pollutants such as benzene, toluene, and xylene, which can have serious health effects and ensures regulatory compliance

It only monitors temperature changes

It measures greenhouse gases but ignores hazardous air pollutants

It focuses only on particulate matter

Question 4: What instrument is commonly used to measure ambient ozone concentrations in air quality monitoring?

Which action should you take?

Choose only one option

Flame ionization detector

Ozone analyzer using UV photometry

Gas chromatograph with an electron capture detector

Infrared analyzer with a tunable diode laser

Question 5: How would you assess the effectiveness of a chemical treatment process in wastewater treatment?

Which action should you take?

Choose only one option

By determining the volume of sludge produced

By checking the effluent's pH value only

By analyzing the physical properties of the effluent

By measuring the reduction in chemical oxygen demand (COD)

Question 6: How do electrostatic precipitators (ESPs) help in pollution control in chemical industries?

Which action should you take?

Choose only one option

By absorbing gases and vapors through porous media

By using high temperatures to incinerate pollutants

By filtering gases using activated carbon

By using an electric field to charge and collect dust particles
