Biomes, Development, Pollution, And You

/in /by

Assignment 1: Discussion—Biomes, Development, Pollution, and You

Each part of the United States has at least one ecological crisis based on location, biome, and industrialization pattern. For example, the Midwest was once a prairie with very fertile soil. However, when people realized that with the right watering and drainage system this area could become productive farmland, there arose ecological problems. The conversion of the prairie to farmland is the root cause of many ecological problems in this region.

Regardless of what biome you consider, humans have likely had an impact on the ecology of that area.

For this assignment, identify the biome in which you live. The following are a few examples of biomes:

  • Tropical rainforests: This biome has high average temperatures, high moisture levels, and high species diversity.
  • Prairies: The prairies have grassland-variable temperatures, variable moisture levels—depending on proximity to mountain ranges—and are mainly dominated by grasses and ungulate herbivores.
  • Deserts: These biomes have hotter average temperatures, low moisture, lower species diversity, and a composition of species limited mainly to those that are adapted to hot temperatures.
  • Temperate forests: The temperate forests have variable temperatures, high moisture levels, and higher species diversity.
  • Taigas: These biomes have colder average temperatures, lower moisture levels, and lower species diversity.
  • Tundras: The tundras have cold average temperatures, low moisture levels, and low species diversity.
  • Coral reefs: These biomes have high average temperatures and high species diversity.
  • Open oceans: These biomes have a wide range of temperatures and species diversity varies.
  • Chaparrals: The chaparrals have higher average temperatures, lower moisture levels, and are dominated mainly by grasses and shrubs.
  • Alpines: These biomes have low average temperatures, low precipitation, and receive high ultraviolet (UV) rays due to high elevation.

Using the readings for this module, the Argosy University online library resources, and the Internet, respond to the following:

  • Explain how humans have impacted the biome in which you live. List the types of environmental damage that have been caused and the species that have been impacted.
  • Describe the major pollution issues for your biome, and elaborate on the sources of this pollution.
  • List any species that have become extinct in this biome.

Support your statements with appropriate examples and scholarly references.

Soils Assignment – Environmental Science

/in /by

Please let me know if the assignment can be completed by 10:00 am tomorrow!  Requirements below!

 

Use the Natural Resources Conservation Service web site (Web soil survey http://websoilsurvey.nrcs.usda.gov/app/HomePage.htm) to gather soils data from five (5) different locations across Louisiana. Make sure you sample from across the state.
For each of the sampled associations, record in an Excel spreadsheet the following data (each should be in column, each column should be labeled):

o o o o o

Name of the soil or soil association
Average elevation where soil is found
Average slope where the soil is found
Depth to water table (if it says “more than 80 inches” use 120) Typical soil profile depth (do not include bedrock in the depth)

Hand in your spreadsheet with your observations.

 

Use your data to make scatter plots of the relationships listed below. Do not

connect your points with a line. Include a best-fit linear regression in all of your plots. Make sure that you also include on the graph the R2 value for the best-fit line. Remember to label your axes (include units). Hand in each of your plots. (14 points)

o Depth to water table (y-axis) vs. average elevation (x-axis) o Depth to water table (y-axis) vs. average slope (x-axis)
o Depth to water table (y-axis) vs. soil profile depth (x-axis) o Soil profile depth (y-axis) vs. average slope (x-axis)

 

Type your answers to the following questions. Use complete sentences (but you can probably answer all of these in a paragraph or two).
You can answer these in a paragraph or even a few sentences.

1. Which two relationships have the highest R2 values? Do these relationship make physical sense to you? Explain why you think there is a correlation between these variables. (2 points)
2. Which two relationships have the lowest R2 values? Explain why you think there is less

 

of a correlation between these variables. (2 points)
3. The depth to the water table is important for growing crops. If you were planning to start a farm, what other soil variables would you like to know about that are not included in the spreadsheet you compiled above? Why? (2 points)

Share another strategy for sustainable design we have not touched on. In your responses to colleagues, give a specific example of how one of the design strategies posted by a classmate is supported by, or supports, ecological economics and/or systems thinking.

Here we go!

Looking back to Module 3 we  reviewed the environmental regulations which surround the designing and production of products.  In modules 2 and 3 we addressed the importance of leadership initiative as well as compliance with environmental regulations.

 

We are now moving into Module 4!  Module 4 launches our review of green production. This module will explore specific green design and manufacturing frameworks.  Our three objectives this week include: •Discuss key sustainability design frameworks •Evaluate the changing nature of green products •Identify potential opportunities and liabilities in “greening” a company’s products

 

Assignment! This week you will review The article “Green Product Design”.  The article was written eight years ago, and while its key concepts are still correct, are all of its conclusions? Research one of its conclusions and share how it may have changed in the intervening years. Write a short analysis paper that summarizes your findings. (Check out the short paper rubric- aim for 2-3 pages of content in your words).

Team Project- Make sure to review the frameworks provided and work with your team to select an appropriate framework and suggest how your company can integrate the framework into their business. If the company has already integrated the framework, describe how they have done so and the results. Integrate the results of your work into Memo 2 of the project.

BOS 3525 Unit II Assignment

Unit II Assignment

You receive a follow-up call from the area director saying the employee filing the original non-formal complaint has provided additional information about the alleged health situation and submitted a formal complaint using the OSHA-7 form, making the complaint a formal complaint. A few days later, an OSHA compliance officer shows up at your facility to perform a comprehensive inspection. The compliance officer presents the proper credentials, and you verify that the compliance officer is employed by OSHA and assigned to the local office.

During the opening conference, the compliance officer provides you with the formal complaint, alleging that employees are exposed to hazardous concentrations of metal fumes in welding areas of the plant, that you have not performed any air sampling to determine exposure levels, that adequate ventilation is not present in welding areas, and that adequate respiratory protection has not been provided to welders. As a part of the inspection, the compliance officer requests the following documents:

 

 Chemical inventory list;

 

 OSHA 300 logs;

 

 Hazard Communication Program, including training records;

 

 any sampling data that you have;

 

 Respiratory Protection Program, including medical clearance letters and training records;

 

 written hazard assessment for personal protective equipment (PPE) used at the facility;

 

 Safety Data Sheets (SDSs) for the metals you use in the production process and any welding rods/wire used in the welding area; and

 

 any other written programs you have that are required by an OSHA regulation.

 

The compliance officer takes a walk-through tour of the facility, spending extra time in the welding areas. During the walk-through, the compliance officer points out several issues believed to be apparent violations. The issues are as follows:

 

 Heavy haze is present in the welding area.

 

 Individuals wearing half-mask air-purifying respirators have full beards.

 

 Employees are using chemicals that could be injurious to the eyes, and no emergency eyewash is present.

 

 Eyewash is present in another area of the plant that is covered in dust, and there is no indication of recent operation or inspection.

 

 Employees are using chemicals that could be absorbed through the skin and are not using any gloves.

 

 Employees are performing maintenance inside a press with no lock-out/tag-out applied.

 

 No written lock-out/tag-out program is available at the time of the inspection.

 

 Welding operation is performed near flammable materials, and no fire watch present.

 

 There is no record of training for fork truck drivers.

 

 Extension cords are stretched across walkways.

 

 Three containers are present in the plant with no label present on any of the containers.

 

 An employee could not find a SDS for the chemical he or she was using.

 

The compliance officer asks for a private conference room and a list of non-managerial employees. He tells you that he intends to interview four non-managerial employees before leaving for the day. He also states that he will return the next day to collect some air samples at the facility.

You are worried about the number of citations and penalties that you may face. Provide a document summarizing the steps you would take as soon as the compliance officer leaves, and the steps you believe you could have taken during the walk-through that may have resulted in a quick-fix penalty reduction.

Your document must be at least three pages in length, not counting the title or reference pages. You must also include at least one reference using appropriate APA style.

1. Please solve the following problem, indicating your response on a Word document and submitting the document via File Upload.

Using the following formula, solve the problem below, and show your work.

TWA = CaTa + CbTb + … + CnTn                                 8

TWA = Time-Weighted Average
Ca = Concentration of contaminant during the sampling period “a“
Ta = Time of sampling period “a“
Cb = Concentration of contaminant during the sampling period “b”
Tb = Time of sampling period “b“
Cn = Concentration of contaminant during the sampling period “n“, where “n” is the last of a series of contaminants
Tn = Time of sampling period “n“

 

Note: All concentrations are in parts contaminant per million parts of air or milligrams of contaminant per cubic meter of air. Air Sampling Problem: You are an industrial hygienist that is conducting personal sampling on a worker who is overseeing a production process involving use of toluene (Note: The Occupational Safety and Health Administration has established a Permissible Exposure Limit of 200 parts per million (ppm)). You are able to measure the following exposures:

500 ppm for 1 hour 100 ppm for 4 hours 225 ppm for 3 hours What is the calculated TWA? What would you tell plant management in terms of exposure to toluene and compliance with the PEL?

UNIT VIII BOS 4301

 

White Paper

 

You are an industrial hygienist for a major pharmaceutical company. The CEO has contacted you regarding a new product line that will be produced in your facility. The new product involves the handling and use of an engineered nanomaterial. To date, your company’s health and safety program has not had to address any safety concerns associated with handling and use of these materials.

 

Using the NIOSH document from the required reading as your authoritative source

(http://www.cdc.gov/niosh/docs/2014-102/pdfs/2014-102.pdf), prepare a three- to five-page “white paper” that provides an overview of engineered materials and includes a discussion of the following:

 

 background and industry overview of engineered nanomaterials,

 

 exposure control strategies,

 

 nanotechnology processes and engineering controls,

 

 hazard control evaluations,

 

 health hazards associated with exposures, and

 

 conclusions and recommendations.

 

As you prepare your paper, keep in mind that this should be a high-level overview that is understandable to all employees in the organization: from upper management to production workers. All sources used, including your textbook, should be cited and referenced properly using APA format.
