- design a waste management plan or the steps that should be taken to decontaminate a waste generated from a food chemical industry and a laboratory that handles radioactive materialsThe Lazy River Environmental Group organized a major cleanup of the pollution from the old factory in late 2010. Measurements of pollution in river sediments before and after the cleanup were analyzed to determine the effectiveness of the cleanup. Select the Sediment Pollutant Over Time dataset and follow the interactive to graph the data. What statement best describes the results of the clean up?Explain why it is of prime importance to analyze water supplies that serve industrialized communities.
- The table below shows the water quality results of palm oil mill effluent (POME)which you have analyzed in your laboratory. You are given a task to proposemitigation options for the palm oil mill after interpreting the findings. Interpretthe characteristics of POME and its potential effect on the aquatic system to helpyou in designing the mitigation options. Parameters Value Department of Environment (DOE) Limit pH 3.4 - 4.8 5 - 9 Biochemical Oxygen Demand (BOD) (mg/L) 25,000 - 43,750 100 Chemical Oxygen Demand (COD) (mg/L) 80,000 - 100,000 100 Oil and Grease (mg/L) 4,000 - 5,000 10Elaborate on the industrial processes of water purification and wastewater treatment. In your answer, please explain in detail the theory and practice of each process, similarities and differences between these processes, and describe steps that you would implement to ensure maximum efficiency in each process.Could we research about waste reduction and recycling management programs by state university or academy? Implementing comprehensive waste management systems can significantly reduce emissions from waste. This includes promoting waste reduction, recycling or upcycling, and composting for organic waste. Thank you
- What methods or methods do you think are most appropriate when looking at eutrophication solutions? Why?Examine the figure below and answer the following questions using the letters below (type, A, B, C, or D in the blanks) a. Which zone has the lowest Biological Oxygen Demand? b. Which zone has the lowest Dissolved Oxygen? c. Which zone has the highest Biological Oxygen Demand? d. Which zone shows the greatest change in Dissolved Oxygen? Types of organisms Normal clean water organisms Trash fish Fish absent, : (carp, gar. : fungi, sludge (Trout, perch, bass, mayfly, stonefly) Trash fish (carp, gar,: leeches) worms, bacteria (anaerobic) leeches) 8 ppm Dissolved 8 ppm oxygen (ppm) Biological oxygen demand Decomposition Septic Zone Rec very Zone Clean Zone Clean Zone Zone B C 近A new analytical method to detect pollutants (D) in water is being tested. This new method of chemical analysis is important because, if adopted, it could be used to detect three different contaminants-organic pollutants (O), volatile solvents (V), and chlorinated compounds (C)-instead of having to use a single test for each pollutant. The makers of the test claim that it can detect high levels of organic pollutants with 99.7% accuracy, volatile solvents with 99.95% accuracy, and chlorinated components with 89.7% accuracy. If a pollutant is not present, the test does not signal. Samples are prepared for the calibration of the test and 60% of them are contaminated with organic pollutants, 27% with volatile solvents, and 13% with traces of chlorinated compounds. A test sample is selected randomly. (a) What is the probability that the test will signal? (b) If the test signals, what is the probability that chlorinated compounds are present? Note: Use the notations in the brackets to…
