General Information

Overview

In Environmental Chemistry, you will examine how chemical processes shape the condition of the environment and influence the decisions we make about managing land, water and energy. You will explore why certain problems emerge, how we detect them and what chemistry can tell us about the best way to respond. You will begin by looking at the major environmental spheres and the standards used to judge environmental quality. From there, you will investigate natural waters and the chemical signals that reveal whether an aquatic system is healthy or under stress. You will also study acid mine drainage and other forms of contamination to understand how pollutants move and why some sites are harder to remediate than others. As the term continues, you will turn your attention to the atmosphere. You will explore the chemistry behind ozone loss, air pollution, smog and the greenhouse effect, and you will examine the evidence that links human activity to climate change. You will then consider how energy choices, industrial processes and natural systems interact to influence emissions and long-term environmental quality. You will also work with the chemistry of toxic metals, sampling needs and environmental monitoring before finishing with radioactivity and risk communication. By the end of the term, you will be able to interpret environmental data and explain the chemical behaviour that drives major environmental issues.

Important note: Students enrolled in a subsequent unit who failed their pre-requisite unit, should drop the subsequent unit before the census date or within 10 working days of Fail grade notification. Students who do not drop the unit in this timeframe cannot later drop the unit without academic and financial liability.

Attendance Requirements

All on-campus students are expected to attend scheduled classes - in some units, these classes are identified as a mandatory (pass/fail) component and attendance is compulsory. International students, on a student visa, must maintain a full time study load and meet both attendance and academic progress requirements in each study period (satisfactory attendance for International students is defined as maintaining at least an 80% attendance record).

Website

This unit has a website, within the Moodle system, which is available two weeks before the start of term. It is important that you visit your Moodle site throughout the term. Please visit Moodle for more information.

Class and Assessment Overview

Recommended Student Time Commitment

Assessment Grading

This is a graded unit: your overall grade will be calculated from the marks or grades for each assessment task, based on the relative weightings shown in the table above. You must obtain an overall mark for the unit of at least 50%, or an overall grade of 'pass' in order to pass the unit. If any 'pass/fail' tasks are shown in the table above they must also be completed successfully ('pass' grade). You must also meet any minimum mark requirements specified for a particular assessment task, as detailed in the 'assessment task' section (note that in some instances, the minimum mark for a task may be greater than 50%). Consult the University's Grades and Results Policy for more details of interim results and final grades.

Previous Student Feedback

Feedback, Recommendations and Responses

Every unit is reviewed for enhancement each year. At the most recent review, the following staff and student feedback items were identified and recommendations were made.

Feedback from Student feedback

Feedback

Some students requested more worked examples for the mathematical-based questions.

Recommendation

Review tutorial content to provide further worked examples where possible. Consider options for additional mathematical support for students.

Feedback from Student feedback

Feedback

Some students experienced confusion with the lecture material labelling and understanding background textbook readings.

Recommendation

Review and update the organisation of unit content as necessary. Provide resources for key concept review.

Unit Learning Outcomes
On successful completion of this unit, you will be able to:
  1. Explain the chemical principles relating to the chemistry of the different spheres of the environment: atmosphere, hydrosphere, lithosphere and biosphere
  2. Apply environmental chemical concepts and analytical reasoning to interpret water, air, soil, and pollutant information, and evaluate environmental quality using scientifically valid approaches
  3. Describe the important environment regulating authority and environmental guidelines
  4. Use research skills to obtain information relating to environmental chemical concepts, environmental issues and current approaches to solve these.

Academic Integrity Statement

As a CQUniversity student you are expected to act honestly in all aspects of your academic work.

Any assessable work undertaken or submitted for review or assessment must be your own work. Assessable work is any type of work you do to meet the assessment requirements in the unit, including draft work submitted for review and feedback and final work to be assessed.

When you use the ideas, words or data of others in your assessment, you must thoroughly and clearly acknowledge the source of this information by using the correct referencing style for your unit. Using others’ work without proper acknowledgement may be considered a form of intellectual dishonesty.

Participating honestly, respectfully, responsibly, and fairly in your university study ensures the CQUniversity qualification you earn will be valued as a true indication of your individual academic achievement and will continue to receive the respect and recognition it deserves.

As a student, you are responsible for reading and following CQUniversity’s policies, including the Student Academic Integrity Policy and Procedure. This policy sets out CQUniversity’s expectations of you to act with integrity, examples of academic integrity breaches to avoid, the processes used to address alleged breaches of academic integrity, and potential penalties.

What is a breach of academic integrity?

A breach of academic integrity includes but is not limited to plagiarism, self-plagiarism, collusion, cheating, contract cheating, and academic misconduct. The Student Academic Integrity Policy and Procedure defines what these terms mean and gives examples.

Why is academic integrity important?

A breach of academic integrity may result in one or more penalties, including suspension or even expulsion from the University. It can also have negative implications for student visas and future enrolment at CQUniversity or elsewhere. Students who engage in contract cheating also risk being blackmailed by contract cheating services.

Where can I get assistance?

For academic advice and guidance, the Academic Learning Centre (ALC) can support you in becoming confident in completing assessments with integrity and of high standard.
