In this course, there are many types of assignments given to students like individual assignments, group-based assignments, reports, case studies, final year projects, skills demonstrations, learner records, and other solutions given by us. We also provide Group Project Presentations for Irish students.
In this section, we are describing some tasks. These are:
Assignment Task 1: Describe the chemical composition of key environmental media such as soils, freshwater, and seawater.
Soils, freshwater, and seawater are all unique in their chemical compositions. However, they all share some common elements.
Soil is a complex mixture of minerals, organic matter, water, and air. The mineral content of soil varies depending on the parent material from which it is formed and the subsequent weathering processes that have taken place. The most common minerals in the soil are oxides of iron, aluminum, silicon, calcium, magnesium, potassium, and sodium. Soil organic matter is composed of plant and animal residues, dead microorganisms, and synthetic materials from human activities.
Freshwater is a naturally occurring water body that composes 0.3% of Earth’s water supply. It exists in three main forms: surface water (lakes and rivers), groundwater (aquifers), and atmospheric moisture (clouds and rain). Surface water makes up the majority of freshwater, followed by groundwater. The chemical composition of freshwater varies depending on its source, but it typically contains dissolved minerals like calcium, magnesium, sodium, potassium, and chloride.
Seawater is a type of saltwater that covers approximately 71% of Earth’s surface. It is composed of 97.5% water, 2.5% dissolved minerals, and a small amount of organic matter. The most abundant dissolved mineral in seawater is sodium chloride, followed by magnesium sulfate, calcium carbonate, and potassium sulfate.
Assignment Task 2: Identify the need for and range of chemical analyses required for environmental investigations.
When conducting environmental investigations, it is often necessary to collect and analyze samples of soil, water, air, or other materials. The type and scope of chemical analyses required will vary depending on the specific goals of the investigation. In some cases, only basic tests may be needed to identify the presence or absence of certain substances.
In other cases, more comprehensive testing may be necessary to determine the concentrations of various substances present in a sample. Whatever the specific requirements may be, it is important to choose an experienced laboratory that is able to provide the needed services.
Assignment Task 3: Appreciate and demonstrate an understanding of the methodologies and instrumentation used for a range of chemical analyses.
There are a variety of methodologies and instrumentation that can be used for chemical analyses. The specific approach that is used will depend on the nature of the sample being analyzed and the desired results. In general, however, these techniques can be broadly categorized into two main types: qualitative and quantitative.
Qualitative analysis is used to identify the presence or absence of certain components in a sample. This type of analysis typically does not provide information on the exact amount of a given component present in a sample. Quantitative analysis, on the other hand, is used to determine the precise concentration of one or more components in a sample.
Both qualitative and quantitative analyses have their own advantages and disadvantages, so it is important to select the right approach for each individual investigation. The right methodology and instrumentation can be critical to obtaining accurate and reliable results.
Assignment Task 4: Describe the principle of selected analytical procedures.
Selected analytical procedures are used to provide an indication of the amount and type of chemical pollutants present in a given environmental sample. The procedures used include gas chromatography, liquid chromatography, and tandem mass spectrometry. In general, these procedures allow for the determination of concentrations of individual pollutants down to the parts-per-trillion range.
The use of analytical procedures allows for the identification and quantification of chemical pollutants in environmental samples. This information is then used to assess the extent and severity of pollution, and to help inform decisions about appropriate remediation measures.
Assignment Task 5: Identify and deal with sources of error in the analytical techniques.
There are many sources of error that can occur in analytical techniques. To identify and deal with these errors, it is important to understand their effects on the results of the analysis. Some common sources of error include:
Instrumentation Error: This type of error occurs when the instruments used to make measurements are not properly calibrated or have other errors. This can lead to incorrect readings and inaccurate results.
Sample Handling Error: This type of error can occur during sample preparation or during the actual analysis. Improper sample handling can lead to contamination or degradation of the samples, which will impact the accuracy of the results.
Operator Error: This type of error occurs when the operator performing the analysis is not properly trained or does not follow the proper procedures. This can also lead to incorrect readings and inaccurate results.
Incomplete or incorrect data: This can occur if data is not collected properly, or if certain data points are omitted. It can also occur if the wrong type of data is collected (e.g. instead of measuring the weight of an object, the volume is measured) In.complete or incorrect data will lead to inaccurate results.
There are many other sources of error that can occur in analytical techniques. To ensure accurate and reliable results, it is important to carefully control all aspects of the analysis, from sample preparation to data analysis. Any potential sources of error should be identified and addressed prior to conducting the analysis.

Assignment Task 6: Undertake chemical analyses of various materials.
There are many different types of chemical analyses that can be performed on materials, depending on the specific properties that need to be measured. Some common analyses include elemental analysis, compositional analysis, and physical property testing. Chemical analyses can provide vital information about the make-up of a material and how it will interact with other substances.
The results of chemical analysis can be used to determine the composition and structure of a material, as well as its physical properties. This information can be used to identify potential problems with the material and to suggest ways to improve its performance. It can also help in the selection of appropriate materials for specific applications.
In addition, chemical analyses can be used to monitor environmental samples for pollutants. This information can be used to assess the extent and severity of pollution and to help inform decisions about appropriate remediation measures.
There are many different methods that can be used to perform chemical analyses. The most appropriate method will depend on the specific properties that need to be measured, as well as the nature of the sample. Common analytical methods include spectroscopy, chromatography, and mass spectrometry.
Assignment Task 7: Analyse chemical data with respect to thresholds and other environmental standards or regulations.
It is important to consider chemical thresholds and environmental standards or regulations when analyzing data.
The purpose of chemical thresholds is to provide a level of protection for public health and the environment. Thresholds are set at a level that, if the exposure occurred, would be unlikely to cause an adverse health effect. However, because threshold levels are conservative, they may not always protect people or the environment from potential harm.
Environmental standards or regulations are also set in order to protect public health and the environment. They may be more stringent than thresholds, but they also take into account economic and social costs as well as technological feasibility. By understanding both chemical thresholds and environmental standards or regulations, one can better analyze data with respect to potential impacts on public health and the environment.
Assignment Task 8: Source information to help interpret the data.
When analyzing data, it is important to have a good understanding of the underlying principles involved. In order to do this, it is often necessary to consult with experts in the field.
In the case of chemical data, it is important to understand the concepts of thresholds and environmental standards or regulations. These concepts can be difficult to understand without a background in chemistry or environmental science. As such, it is often necessary to consult with experts in these fields in order to properly interpret the data.
Another important consideration when interpreting data is the potential for error. Any sources of error should be identified and addressed prior to conducting the analysis. This will help ensure that the results of the analysis are as accurate and reliable as possible.
Finally, it is important to consider the context in which the data was collected. This includes the type of sample, the method used to collect the data, and the geographical location where it was collected. All of these factors can influence the results of an analysis and should be taken into account when interpreting the data.
Assignment Task 9: Write a report on the results of the chemical analysis.
Once the data has been analyzed, it is necessary to write a report summarizing the findings. This report should include a description of the data, as well as an interpretation of the results.
It is also important to identify any limitations of the analysis and to suggest ways in which the methodology could be improved. Finally, the report should recommend any further actions that may be necessary in light of the findings.
Assignment Task 10: Engage in informed group discussions.
When analyzing chemical data, it is important to engage in informed group discussions. This will help ensure that all of the relevant issues are considered and that everyone has a chance to share their thoughts and opinions.
Group discussions can also be helpful in identifying any areas of disagreement or confusion. By working through these issues together, everyone can gain a better understanding of the data and the potential implications of the findings.
