What pollutants have impact on air quality and how do they enter the atmosphere? Discuss briefly the effects of air pollution to human health, animals and plants. Provide certain control measures that can be adopted to reduce the air pollutar emitted by automobiles Apart from being a nuisance, noise pollution resulted from construction projects ca have damaging effects on people and the environment. Describe ways that noi pollution can harm you and your community. And suggest ways that can be used protect workers from hazardous noise exposure.

Civil Engineering For each of the following environmental pollution scenarios, identify TWO PHASE partitioning processes that could be important:a. A leaking underground storage tank full of diesel fuel.b. A lake fed by a spring that flows from groundwater in contact with an aquifer enriched with arsenic sulfide minerals.c. A naturally occurring methane seep that discharges into a muddy pond.d. Hydrochloric acid spill in a limestone-lined lake.

Q // A residential city with a growing population of 50,000 people is experiencing challenges related to wastewater management. The city council has proposed building a combined wastewater treatment plant to ensure that domestic and industrial wastewater is treated effectively, meeting regulatory standards for discharge. The community has identified the need for an engineering solution that considers environmental, technical, and operational aspects. Scenario Details: Each person in the city consumes an average of 200 liters of water per day, and the organic load generated per person is 40 grams daily. The city also houses light industries that generate 0.25 million liters per day (MLD) of wastewater with a BOD, concentration of 600 mg/L. Environmental regulations mandate that treated wastewater discharged from the plant must not exceed a BOD5 of 20 mg/L. The treatment plant must be designed to operate efficiently under seasonal temperature variations, with temperatures reaching 35°C…

Calculate a risk-based groundwater standard (in ppb) for the chemical 1,2-dichloroethane for a residential homeowner where the person’s well used for drinking water is contaminated with 1,2-dichloroethane. Assume the risk is for an average adult who weighs 70 kg. The state where you work has determined that an acceptable risk is one cancer occurrence per 106 people. Use the values for route of intake, exposure frequency, exposure duration, and averaging time provided for residential use in the following table 6.14. Assume an oral slope factor for 1,2-dichloroethane of 9.2x10-2 per (mg/kg)/day.
