HSC 3002 Environmental Toxicology and Human Health


Environmental toxicology is a multidisciplinary domain of science, which occupies an important niche, overlapping the fields of toxicology, environmental health, and public policy. While studying the adverse health effects of chemical, biological, and physical agents on living organisms in the ecosystems, environmental toxicology focuses on humans and therefore plays an important role in addressing public health challenges. Over the years, environmental toxicology research has been providing tools and scientific evidence to policy-makers and the public in preventing substantially greater environmental degradation, including adverse human health impacts.

In East Asia, with the increasing number of environmental problems, there is a pressing need for immediate health solutions, and environmental toxicology is expected to increasingly play an important role. More fundamental and applied research must be carried out to deal with the public health challenges in terms of environmental problems and to increase the body of scientific knowledge in this field. While environmental toxicology receives increasing attention and shows significant growth, the number of articles published in international journals on environmental toxicology is still relatively limited. As society changes due to introduction of new technologies and the challenge of sustainable development in the face of increased human population, especially in the East Asian region, the role of environmental toxicology in enlightened public health and public policy will become even more important.

Air pollution from both natural and anthropogenic sources now constitutes one of the greatest public health challenges in East Asia at the present time. N. F. Suhaimi and J. Jalaludin conducted a search of journal articles and identified seven studies which used biomarkers to understand the association between air particles exposure and the development of respiratory problems resulting from the damage in the respiratory system. While finding the application of biomarkers in epidemiological studies of health effects caused by air particles in both environmental and occupational health to be inchoate, they concluded that biomarkers can unravel the complexity of the connection between exposure to air particles and respiratory health. N. A. M. N. Rawi et al. carried out a cross-sectional study among Malay children in Selangor to determine the indoor air quality (IAQ) and its association with respiratory health.

They measured the levels of particulate matters (PM), volatile organic compounds (VOCs), carbon monoxide (CO), carbon dioxide (CO2), air velocity (AV), temperature, and relative humidity and found that abnormality of FVC% among children was associated with the concentrations of PM2.5 and CO, while abnormality of FEV1% among children was associated with the concentration of CO. In addition, they found that wheezing was associated with concentrations of PM2.5, PM10, and CO. M. Watanabe et al. also studied the effects of air pollution on the pulmonary function of school children but targeted at the Asian dust storm (ADS). They identified seven ADS days from 2012 to 2013 in the Shimane Prefecture of Japan and observed a larger change in morning peak expiratory flow (PEF) in children after ADS exposure in 2012 (−8.17 L/min versus −1.17 L/min). Using airborne particles collected on ADS days to stimulate THP-G8 cells, they found interleukin-8 transcriptional activity was also higher when particles collected in 2012 were used. Therefore, they argue that the influence of ADS on pulmonary function of children may be related to interleukin-8 production.

Lopes Write Policy

For assignments that need to be submitted to Lopes Write, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me.

Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes.

Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own?

Welcome to class

Hello class and welcome to the class and I will be your instructor for this course. This is a -week course and requires a lot of time commitment, organization, and a high level of dedication. Please use the class syllabus to guide you through all the assignments required for the course. I have also attached the classroom policies to this announcement to know your expectations for this course. Please review this document carefully and ask me any questions if you do. You could email me at any time or send me a message via the “message” icon in halo if you need to contact me. I check my email regularly, so you should get a response within 24 hours. If you have not heard from me within 24 hours and need to contact me urgently, please send a follow up text to

I strongly encourage that you do not wait until the very last minute to complete your assignments. Your assignments in weeks 4 and 5 require early planning as you would need to present a teaching plan and interview a community health provider. I advise you look at the requirements for these assignments at the beginning of the course and plan accordingly. I have posted the YouTube link that explains all the class assignments in detail. It is required that you watch this 32-minute video as the assignments from week 3 through 5 require that you follow the instructions to the letter to succeed. Failure to complete these assignments according to instructions might lead to a zero. After watching the video, please schedule a one-on-one with me to discuss your topic for your project by the second week of class. Use this link to schedule a 15-minute session. Please, call me at the time of your appointment on my number. Please note that I will NOT call you.

Please, be advised I do NOT accept any assignments by email. If you are having technical issues with uploading an assignment, contact the technical department and inform me of the issue. If you have any issues that would prevent you from getting your assignments to me by the deadline, please inform me to request a possible extension. Note that working fulltime or overtime is no excuse for late assignments. There is a 5%-point deduction for every day your assignment is late. This only applies to approved extensions. Late assignments will not be accepted.

If you think you would be needing accommodations due to any reasons, please contact the appropriate department to request accommodations.

Plagiarism is highly prohibited. Please ensure you are citing your sources correctly using APA 7th edition. All assignments including discussion posts should be formatted in APA with the appropriate spacing, font, margin, and indents. Any papers not well formatted would be returned back to you, hence, I advise you review APA formatting style. I have attached a sample paper in APA format and will also post sample discussion responses in subsequent announcements.

Your initial discussion post should be a minimum of 200 words and response posts should be a minimum of 150 words. Be advised that I grade based on quality and not necessarily the number of words you post. A minimum of TWO references should be used for your initial post. For your response post, you do not need references as personal experiences would count as response posts. If you however cite anything from the literature for your response post, it is required that you cite your reference. You should include a minimum of THREE references for papers in this course. Please note that references should be no more than 5 years old except recommended as a resource for the class. Furthermore, for each discussion board question, you need ONE initial substantive response and TWO substantive responses to either your classmates or your instructor for a total of THREE responses. There are TWO discussion questions each week, hence, you need a total minimum of SIX discussion posts for each week. I usually post a discussion question each week. You could also respond to these as it would count towards your required SIX discussion posts for the week.

I understand this is a lot of information to cover in 5 weeks, however, the Bible says in Philippians 4:13 that we can do all things through Christ that strengthens us. Even in times like this, we are encouraged by God’s word that we have that ability in us to succeed with His strength. I pray that each and every one of you receives strength for this course and life generally as we navigate through this pandemic that is shaking our world today. Relax and enjoy the course!
