Announcement of the ASTS Satellite Conference/Mixer at SOT
2013-02-15 22:54:59
You are cordially invited to the ASTS Satellite Conference/Mixer held in conjunction with the 52nd Society of Toxicology (SOT) Annual Meeting in San Antonio, Texas, on Wednesday March 13 2013, from 6 – 9 pm, at the Hilton Palacio del Rio (200 South Alamo, San Antonio, TX 78205).
Highlights of the evening include a presentation by Dr Evans Afriyie-Gyawu on the Toxicological and Public Health Implications of the Use of Scrap Rubber Tires for Smoking Meat in Developing Countries (see Abstract below). Please register by sending the following information by email, to the ASTS General Secretary at: We encourage our colleagues from Africa to give a 5-minute synopsis of their poster or research interest. If interested, please indicate on the form. Name of attendee: Institution and Position: Abstract title and # (if applicable): Country:
Presentation Title: Toxicological and Public Health Implications of the Use of Scrap Rubber Tires for Smoking Meat in Developing Countries. Evans Afriyie-Gyawu, PhD, MPH1; Terry Williams-Cointault, PhD1; Padmini Shankar, PhD, MS, MSc., RD, LD2; Angela Otumfuor1; Ahmed Adu-Oppong, PhD, MBA, MHA, MedSc3; Brian Bossak, PhD, MPH1. 1Jiann-Ping Hsu College of Public Health, 2College of Health and Human Sciences, Georgia Southern University, Statesboro, GA; 3School of Medical Sciences, University of Cape Coast, Cape Coast, Ghana. Abstract Many slaughter houses, “abattoirs”, in some developing countries (such as Ghana and Nigeria) are known to frequently use open fires, set with scraps of automobile tires, to singe the fur of slaughtered goats, sheep, cows, etc. intended for human consumption. According to a veterinarian who inspects the slaughtering process and ensures the carcasses are “free” from diseases, this has been a common practice for well over 50 yr. This is a huge potential health risk because automobile tires are made of various hazardous chemicals and materials that, when released into the environment under ambient conditions (e.g., open fire burning), can contaminate the meat and the environment. A report obtained via the U.S. Environmental Protection Agency delineates that chemicals emitted through open tire burning include carbon monoxide, sulfur oxides, nitrogen oxides, particulate matter – such as volatile organic compounds (e.g., benzene), dioxins, polycyclic aromatic hydrocarbons (PAHs, e.g., benzo[a]pyrene), polychlorinated biphenyls (PCBs), and heavy/toxic metals/metalloids (e.g., arsenic, mercury, cadmium, chromium, etc.). Human exposures to these chemicals occur through ingestion (e.g., meat and meat products smoked with scrap rubber tires) and inhalation (indoor and outdoor air polluted with the tire-fire smoke). Thus, the toxicological and public health impact of this practice on the slaughterhouse operators, consuming public, individuals living in close proximity to the slaughterhouses, and the entire ecosystem cannot be overemphasized. The main objectives are to discuss the: 1) chemicals generally present in rubber tires, 2) pollutants emitted via scrap rubber tire burning, 3) types and levels of contaminants in the tire-smoked meat, and 4) potential toxicological and public health implications associated with using scrap rubber tires for smoking meat and other foodstuffs. We also highlight our current research activities in Ghana, West Africa, related to this practice, as well as some preliminary findings. Finally, it is anticipated that this presentation will heighten awareness of this practice as a potential health risk particularly in developing countries, and stimulate further scientific investigations into this food and environment-related issue.
2013 Conference Announcement. Update: SUSPENDED
2012-11-27 18:00:18
<b>2013 ASTS Conference and Training Workshop </b>
---------------------------------------- Novermber 27, 2012 Dear Colleagues, I regret to inform you that due to security concerns resulting from current events in Egypt and the region in general, our colleagues in Egypt have advised us to suspend plans for the conference in February until further notice. We are very saddened and disappointed by this turn of events, but the security of all conference attendees is of utmost importance to ASTS and our Egyptian counterparts, hence we have decided to heed the advise to cancel the conference until such a time as events on the ground are stable enough for us to resume planning. In the meantime, we will be working with our sponsors and collaborators, to assess the feasibility of having a satellite symposium in tandem with the SOT meeting in San Antonio, Texas, in March 2013. Thank you for your support during these two years of preparation and we look forward to your continued support to ASTS. Sincerely, Lilian Yengi, Ph.D. President ---------------------------------------- 2013 
Program and Registration Message from the President October 21, 2012 Dear Colleagues It is a singular pleasure for me to cordially invite you to attend the 2013 ASTS Conference and Training Workshop from February 10-15, 2013, in Ismailia, Egypt. As those of you who have been on this journey with us since 2010,when we first announced with pride that ASTS will make its first foray out of sub-SaharaAfrica, it has been a journey of discovery, excitement, yet fraught with many challenges that sometimes find usat the mercy of events outside our control. Nevertheless, the one thing that remained was the dedication and determination of the ASTS Leadership team and our esteemed partners and colleagues in Egypt who worked tirelessly against all odds, to ensure that this conference takes place. A culmination of this exemplary collaboration and teamwork is that ASTS is finally realizing the dream borne at the ASTS meeting, at Society of Toxicology (SOT) in Washington DC in 2010.
At this conference, we will engage scientists conducting global health research and bring to the table individuals who have been part of risk assessment and risk management practices in the developed countries. It is hoped that feasible approaches that take into consideration Africa’s geopolitical and cultural divides will be identified, discussed and prioritized to guide future interventions. The United States National Institute of Environmental Health Sciences (NIEHS), Toxicology Excellence for Risk Assessment (TERA), United States Environmental Protection Agency (US EPA), and United Nations Environment Program (UNEP) are among some of the governmental and nongovernmental agencies that are partnering with ASTS for this conference. In addition, the Scientific Committee is comprised of some of the key opinion and thought leaders in toxicology from top universities in Africa as well as Europe and the USA. Mercure Ismailia Forsan Island Hotel Since ASTS was founded in 1998, it has made laudable strides in promoting the science of toxicology on the continent by hosting conferences and trainings in Africa, inviting policy makers from Africa to attend ASTS-sponsored workshops, and sponsoring many African scientists to SOT annual meetings in the USA. We continue to expand on these initiatives, believing they are critical to the quest to improving human health and the environment and minimizing the impacts of exposures to chemicals in Africa. This conference and training will continue to build on these themes, vision and mission of ASTS, as well as provide opportunities for attendees to meet other scientists and thought leaders,public policy makers, network with friends, colleagues and hopefully, deepen their knowledge in toxicology, risk assessment and other research topicsrelevant to them. We therefore, strongly encourage all interested scientists to consider research and analysis to showcase at this conference in the areas listed in the programs. Hammock Tours Conference registration is now open on the TERA website. The link to the registration page is In the meantime, if you have any questions please feel free to contact me at, or any of the other contact persons identified in the program on the TERA registration page. Thank you very much for your steadfast support and dedication to ASTS. I hope to see you in Ismailia. Sincerely, Lilian G. Yengi, Ph.D. ASTS President
