He received his Master’s Degree in Environmental Health Engineering from NYU’s Tandon School of Engineering and proceeded to earn his DrPH from Columbia University in 1984. Prior to NYU, Dr. Caravanos was a tenure Full Professor at City University of New York (Hunter College), School of Public Health where he directed the ABET accredited MS degree program in Environmental and Occupational Health Sciences (EOHS) as well as the MPH EOHS degree for almost 40 years. In 2017, he was designated Professor Emeritus at the CUNY Graduate School of Public Health and Health Policy. He is board certified in industrial hygiene (CIH) and prides himself as being a practicing field-based environmental and occupational health scientist. Since 2005, Dr. Caravanos has worked with the international NGO Pure Earth (formerly Blacksmith Institute) helping to create its Toxic Site Inventory Program. In addition to his full time academic duties, he is the Director of Research at Pure Earth where he coordinates and facilitates scientific manuscript preparation based on assessment and remediation projects completed in low and middle-income countries. He has traveled worldwide assessing lead exposures at used lead-acid battery recycling facilities and pottery manufacturing as well as mercury exposures from artisanal and small-scale gold mining. He has extensive experience in heavy metal assessment using X-ray fluorescence (XRF) Lead Detection technology and LeadCare II Blood testing equipment.
  Abstract

  The growth of the global economy continues to shift numerous low skilled manufacturing jobs to low and middle-income countries. In addition, the increasing demand for processing of recyclables such as e-waste, plastics, and used-lead acid batteries has generated additional economic opportunities for low and middle income countries. The burning of copper wires and cables from e-waste processing is a growing trend that continues to not only pollute urban air but also presents a significant worker respiratory risk. Used automotive lead-acid batteries are also recovered, dismantled and smelted for lead ingot production. And of course, a variety of plastics are collected, sorted and sold for reprocessing with little to no worker protection. The vast majority of these tasks fall on the neediest portion of the population and usually in the low income countries. While data exists on global work related injuries and illnesses, the difficulty in quantifying the burden of occupational illness in this sector often leaves them undetected, and, unfortunately, ignored. Using a series of cases studies, significant exposure issues and challenges facing workers in several growing “industries” in several low and middle income countries will be presented and reviewed. These case studies will showcase the findings of the recent Lancet report on Pollution and Health with specific interpretations and applications to occupational hygiene.

  Promotional Video Clip
  Biography

  Dr. Friesen is a Senior Investigator in the Occupational and Environmental Epidemiology Branch at the U.S. National Cancer Institute. Prior to joining the NCI in 2009, she completed her graduate studies in occupational and environmental health at the University of British Columbia in Vancouver, Canada, and postdoctoral studies at Monash University in Melbourne, Australia, and at the University of California at Berkeley. Dr. Friesen's research has focused on quantitative assessment strategies to minimize exposure misclassification in occupational epidemiologic studies. She has focused on improving exposure estimates, evaluating the robustness of exposure-response relationships to exposure assessment strategies, and using statistical models for both developing exposure metrics and evaluating their exposure-response relationships. By using more refined and more proximal exposure measures, her research has resulted in quantitative exposure-response relationships for several exposure-disease associations that have not previously been published.
  Abstract

  The interdisciplinary field of exposure science, which includes knowledge of chemistry, biology, statistics and epidemiology, is a crucial component of identifying causes of cancer and other health effects in humans using epidemiologic studies. This talk will focus on state-of-the-art approaches used in population-level studies of cancer and chronic diseases. This includes new approaches for occupational data collection from study participants and linking their questionnaire responses to measurement-based exposure estimates to derive exposure estimates for their entire working life that can be used in epidemiologic studies. To illustrate this, two case studies will be presented: exposure to metalworking fluids and bladder cancer risk and exposure to biologically active dusts in agricultural settings (e.g., endotoxin) and lung cancer risk.

  Biography

  Marianne Levitsky was founding President of Workplace Health Without Borders, a non-profit organization that engages volunteers in promoting occupational health for workers everywhere. A senior associate with ECOH, an Ontario consulting firm, she was previously Director, Prevention Best Practices in the Ontario Workplace Safety and Insurance Board, an occupational hygienist with the Ontario Ministry of Labour, and a co-founder of the Toronto Workers’ Health and Safety Legal Clinic. She is adjunct faculty at the University of Toronto and was a member of the Toronto Board of Health. Marianne has received the Hugh Nelson award for excellence in occupational hygiene from the Occupational Hygiene Association of Ontario and the Yant Award from the American Industrial Hygiene Association (AIHA). She has served as chair of the AIHA International Affairs Committee and is an AIHA Fellow and Distinguished Lecturer.
  Abstract

  “Without Borders” implies overcoming boundaries - transcending the limits that restrict us to our own countries, cultures and perspectives. As members of a small profession with its own distinctive culture, Occupational Hygienists have had to transcend borders of many kinds, in efforts to cross-pollinate with other disciplines in an exchange of scientific perspectives. Perhaps no experience has taught us this more unequivocally than the COVID-19 pandemic. We have had to learn unfamiliar paradigms and different ways of looking at disease prevention in multi-disciplinary efforts that brought us together with aerosol scientists, engineers, infection control experts and health care professionals. This path has not been without conflict, as many of us have learned in debates over PPE and aerosol transmission. We have also learned the value of cultural humility, and what the so-called “developed” nations can learn from colleagues all over the world. We have also had to confront the inequities in disease prevention internationally and within our own countries. This talk will build on the experience of Workplace Health Without Borders, an all-volunteer non-profit organization, in exploring these ideas.

  Abstract

  Labour laws are promulgated in Vietnam from 1994. However, regulations about occupational safety and health are only one chapter in the labor laws. In the years of the 2000s, Vietnam's economy has grown very quickly, especially in the field of industrial production and construction, materials manufacture, quarrying, etc. In addition, must be considered the increased rapidity of small and medium enterprises, the number of this enterprises proportion more than 80% of the Vietnamese economy. So, the numbers of fatal accidents and diseases were increasing at construction sites and quarrying. In this context, the Occupational Safety and Health law (OSH law) were issued in 2015. The content and all the guidelines of this law, has focused on making the management regulations about safety to prevent accidents for employees at the workplaces. Moreover, regulations about risk assessment and controlling of hazards in workplaces also prescribed for the companies with a high risk. And, this regulation also prescribed for small and medium enterprises in Vietnam. After four years (from 2015 to now), the accident rate at workplaces has decreased in the sectors of quarrying, construction, materials manufacture, oil and gas. This indicates that OSH law and all the guidelines, regulations about system of accident prevention and occupational diseases, risk assessment and controlling of hazards in workplaces are actually being implemented effectively in Vietnam.

  Abstract

  Professional ethics is a branch of applied ethics, which has its roots in the principles of antique Hippocrat (460-370 BC) then formalized and generalized by Plato (428?-348 BC) and Aristotele (384-322 BC). Today applied ethics is considered to have several branches, including Medical ethics, Bio-ethics, Cyber Ethics, Environmental Ethics, Personal Ethics, Professional Ethics, Public Ethics, International Ethics and so on.
  Several professional organizations on occupational health and safety, including IOHA and ICOH, IEA, IALI have drawn codes of ethics or codes of conduct for the memberships. In these codes, the core principles in professional ethics have remained the same since times of Hippocrat, but certain variation in the contents are observed and a number of additional dimensions have been included in the course of development of the working life. The key principles found in the codes are:
  • Autonomy: Respecting autonomy of the client
  • Beneficence: Doing good: Protection of Life and obligation to help those in need
  • Non-maleficence: Not doing bad, avoiding harm
  • Objectivity: Basing judgements and decisions on evidence and or recognized professional experience
  • Confidentiality: Keeping and protecting the individuals’ secrets
  • Collegiality: Respecting fellow professionals
  • Competence: Maintaining and continuously developing professional knowledge and skill
  • Moderation of financial rewards in relation to service and the ability of the client to pay.
  Numerous threats hurt the professional ethical principles in the contemporary world of work, for example:
  • Value relativism
  • Excessive competition
  • Dominance of economic dimension
  • High rhythm of work life
  • New unexperienced events and activities
  • Ethical incompetence
  • Conflict between institutional/organizational ethics vs. professional ethics
  • Dramatic business scandals (=collapses of business ethics) even in giant multinational corporations.
  Several professionals have reported “ethical stress” at work due to conflict between their professional values and unethical principles of cultures of communities and organizations. Protecting professional ethics is not only the benefit of professionals themselves, but important for the whole international and national communities, enterprises, workers and public at large, i.e. common good. The seven guiding principles by the UK Government Chief Scientific Advisor, sir David King are.
  • Act with skill and care, keep skills up to date
  • Prevent corrupt practice and declare conflicts of interest
  • Respect and acknowledge the work of other scientists
  • Ensure that research is justified and lawful
  • Minimise impacts on people, animals and the environment
  • Discuss issues science raises for society
  • Do not mislead; present evidence honestly.
  High and up to date competence behind the professional independence and support by professional Associations, their ethics codes, support to members and collegial support by fellow-members are crucial in maintaining the principles of professional ethics in the contemporary globalizing world of work. International professional Associations in occupational health and safety should recognize their roles as guardians of professional ethics, they could collaborate more intensively in promotion of ethical dimension in the globalising world of work and provide support for the implementation of the key ethics principles in the everyday life of their memberships.

  Abstract

  Small and medium-sized enterprises (SMEs) account for 97.6% of businesses in Taiwan, and they are important contributors to job creation and economic development. However, SMEs often have higher rates of occupational accidents and worse working environment compared to large enterprises due to the limited resources. To improve the problems and promote occupational hygiene capabilities for SMEs, tiered management based on risk ranking and multiple approaches of compliance inspection, counseling and outreach programs have adopted by Occupational safety and Health Administration of the Ministry of Labor in Taiwan (Taiwan OSHA).
  In respect of chemical management, Occupational Safety and Health Act (OSH Act) has introduced the tools of chemical control banding for exposure assessment. To master the patterns about how to carry out the exposure assessment by enterprises, there are multiple ways utilized including propaganda, counseling and on-site visiting by professional counselors. From 2016 to 2019, Taiwan OSHA has collected patterns from more than 10,000 SMEs. Furthermore, Taiwan OSHA has devised a special subsidy program to assist SMEs to employ or contract medical personnel to conduct occupational health services in accordance with OSH Act.
  In the so-called 3D (difficult, dirty and dangerous) traditional manufacturing industry, Taiwan OSHA assists SMEs to improve the working environment by site counseling and subsidies providing up to US$ 80,000 for each enterprise. From 2014 to 2019, Taiwan OSHA has cooperated with three industries: casting, surface treatment, and dyeing and finishing of textile industry, encouraged more than 150 enterprises to build the working environment safer and healthier, promoted industry investment that totals about US$89 million, and approved subsidies of nearly US$4.33 million.
