About ATA

From Gulf to Ocean, Toxicology Builds Bridges

The time period between the 9th and the 13th centuries was known as “the Golden period of the Arab sciences,” and the Arabs during this Golden Age were involved in toxicology and medicine contributing to sentinel works on toxic substances, such as those by physician and scientist Hunayn bin Ishaq in the 9th century all the way to Ibn al-Suri in the 13th century.

The Arab Toxicologists Association (ATA) is founded by professionals of Arab origin, with expertise in various areas of toxicology and working in Arab countries and all over the world. ATA was established in 2019 as an SOT Special Interest Group. ATA brings together experts from industry, academia, and government to discuss existing and emerging issues and methods for characterizing chemical exposure to help provide insights into toxicological needs in the Arab world and create organizations of toxicology in Arabic countries. ATA also will provide webinars and lectures to increase the awareness and related toxicology research in Arabic communities inside and outside of the United States.
