PUB262 Assessment Task 1 Risk Characterisation Literature Review

Please explain all these points in assignment to complete the requirement of this nicotine topic. Do not leave even single point-line below the structure.very important cover each dot-point in detail.

Reference: Harvard style

Please read each slide and file, which I attached with this assignment detail docx.

  • To understand
    • where issue(NICOTINE) identification and hazard identification fits within the risk assessment framework
    • The types of scientific information critical in this step
  • To be aware of
    • how to access relevant information ABOUT
    • emerging trends in hazard identification
    • how to get started gathering information about your assignment topic.NICOTINE
    • Consider the identity of your hazard NICOTINE.
    • CAS number
    • MSDS also now referred to as SDS (Safety Data Sheet)
    • What is the Chemical structure IS NICOTINE ????
  1. What health benefits or impacts are associated with exposure? TO NICOTINE.
  2. Why is it an issue? LIKE NICOTINE

E.g. Smoking, passive secondary smoking, tobacco

  1. Who is it an issue for?
  2. Is there a potential pathway of exposure? What is it?
  3. Is there potential for interaction with other hazards/stressors? Eg smoking,tobacco
  4. Can you identify a mode of action?
  5. Are there any viable management options?
  6. Does your hazard identification tell you that a risk assessment would be justified?
  • Is there a susceptible subgroup in your population (e.g. lead in children)?
  • What is the nature of the exposure - continuous, periodic, ‘one off’ etc.
  • Can exposure be limited?
  • Is any effect reversible?

Scientific reason e.g. Lab investigation, study.

Health effects of nicotine

  • Others you can think of………
  1. Does the information you have collected justify conducting a risk assessment?
  • If no – why not?
  • Choose another hazard and repeat this process

Additional sources of information to get started.

Identity of chemicals

  • Chemspider: ChemSpider is a free chemical structure database providing fast access to over 34 million structures, properties, and associated information. By integrating and linking chemical compounds from ~500 data sources (http://www.chemspider.com )
  • Material safety data sheets (MSDS) (do web search usually CAS number and MSDS in search term)
  • ChemID Plus: a database of over 390,000 records including chemical structures (http://sis.nlm.nih.gov/chemical.html )

  • Recommendations for future research

Task Description:

This task requires you to prepare a critical review drawing upon international literature regarding an assigned chemical hazard.

You will submit 2 pieces of assessment for this task as per the Course Outline and detailed below.

Task 1a is a voluntary formative assessment task. You will complete a template that provides a summary of your research strategy and findings and outlines the structure of your critical review. You will get the opportunity to receive face-to-face feedback on this task in the Week 4 workshop

Task 1b, your final critical review contributes to 35% of your overall grade for this course.your final review document will:
