Session 15: Airborne Micro- and Nanoplastics: Comprehensive Overview of Exposure, Toxicity and Risk Mitigation Strategies[Symposium Program （Session）]
Airborne nano- and microplastic particles (MNP) pose a significant environmental and public health concern due to their widespread presence and potential toxicological impacts. This session aims to advance our understanding of potential risks from airborne MNP by integrating exposure assessment, hazard identification, and risk management across the plastic life cycle. We will explore the sources and pathways of MNP, focusing on their release mechanisms and interactions with biogeochemical cycles. Advanced methodologies for detecting and quantifying MNP in the air will be discussed, emphasizing novel sampling techniques and analytical methods for assessing human exposure. To elucidate potential health effects of MNP, results of studies using new approach methodologies (NAMs) in lung cell lines and human tissue models will be shared and compared to results of recent inhalation studies in rats, covering clinical chemistry, broncho-alveolar lavage, histopathology, organ burden examinations, and transcriptomics of lung and liver tissues. The session will conclude with strategies for mitigating the risks associated with airborne MNP, exploring innovative technologies aimed at reducing MNP entry into the environment and minimizing human exposure, such as advanced air filtration systems and personal protective equipment.

Session 21: Safety of Recycled Plastic for Food Packaging[Symposium Program （Session）]
Plastic packaging, rPET, is the material that causes the serious pollution. It was not permitted to be used as food packaging in Thailand for long time. Recently, private and public organizations have collaborated to preserve our environment, by considering to reduce the garbage from plastic food packaging which continue increasing. One way of reducing it, the used plastic packaging can be brought back to be processed, in order to reduce the amount of new plastic, particularly rPET, used food packaging, the law of TFDA must be allowed. However, the Thai FDA in collaboration with private sectors, food and drink industries, and the academic institutions, such as Mahidol University, formed a research group to study the possibility and feasibility to allow rPET to be used. The process was done to ament the notification of Food law, but we need the result from research team including the following processes:
· The result of study on the reuse, and method of used rPET food packaging
· The study of the safety assessment process of the recycling industries, the rPET safety assessment method to test the migration by both the laboratory result and mathematical model
· The final result was compiled and submit to the sub-committee on food packaging of Thai FDA to draft the notification of food packaging to include the recycled plastic to be allowed to use
Finally, now we have the new notification on plastic to be used as food packaging. The symposium will describe some detail of the regulation items in the notification and the standards for safety. Furthermore, the process of safety assessment including the result of laboratory analyses and the mathematical model of the possible migration of chemical into food to make sure that it is safe for human consumption.

Workshop 05: Understanding and Mitigating Occupational Heavy Metal Exposure: A Comprehensive Approach[Workshop]
This workshop aims to address the critical aspects of heavy metal exposure in occupational settings and its far-reaching health and ecological impacts. Bringing together experts in toxicology, public health, environmental health, and policy, this workshop will present a multi-disciplinary overview of exposure pathways, health risks, and bioaccumulation of heavy metals such as lead, mercury, arsenic, and cadmium. Sessions will cover advanced detection and monitoring techniques for occupational exposure, emphasizing cutting-edge innovations for accurate and timely assessments. The workshop will also highlight global policy frameworks and regulatory standards governing heavy metal use, disposal, and exposure limits. Real-world case studies will offer practical insights into mitigating risks and enhancing compliance. Attendees will gain a deeper understanding of the interplay between heavy metal contamination, human health, and ecological sustainability, while also discussing sustainable interventions and regulatory challenges to foster safer industrial practices and public health protection. This workshop is geared towards researchers, practitioners, and policymakers committed to advancing occupational and environmental safety.

Workshop 06: High-throughput Technology and Health Effects of Heavy Meatal[Workshop]
With the rapid advancement of technology, particularly the widespread use of high-throughput technologies in medical research, it is now possible to simultaneously detect a wide array of genes, proteins, metabolites, and other biological molecules. This has provided powerful tools for biomarker screening, early monitoring, diagnosis, and the study of mechanism for metal toxicity, including investigations into the underlying health effects and prevention strategies. Compared to traditional experimental methods, high-throughput technologies offer unique advantages, particularly in detecting metal toxicity and facilitating biological monitoring. However, challenges remain in terms of testing standards, cost, validation, and the translation of these technologies into clinical practice. In light of these issues, this workshop, organized with input from esteemed professionals in academia and specialized institutions, aims to highlight current achievements and future directions in understanding the health effects of heavy metals. The session will foster constructive dialogue and interaction, driving the field toward meaningful advancements.
The health impacts of heavy metals and industrial elements remain a critical global challenge. Heavy metals such as lead, mercury, cadmium, and arsenic pose severe risks to human health, including neurotoxicity, carcinogenicity, and endocrine disruption. These metals are encountered through sources like old paint, water pipes, cigarette smoke, contaminated soil, and industrial waste, with vulnerable populations, particularly children, facing the greatest risks. Mining and industrial activities exacerbate environmental contamination, leading to significant health and ecological impacts. Understanding the mechanisms of exposure and developing strategies to mitigate these risks are essential to safeguarding public health and ecosystems.
In parallel, the study of essential and non-essential elements, such as sulfur, selenium, and tellurium —raise concerns due to environmental pollution and health risks from their extraction and manufacturing. These metals are crucial for sustainable technologies, but managing the health risks related to their use is essential. To address these challenges, cutting-edge high-throughput technologies are being harnessed to screen the effects on biological systems, identify affected genes and pathways, and develop early warning systems for environmental contamination. These technologies enable the monitoring of heavy metal impacts, the early detection and prevention of related diseases, and the development of detoxification methods. This workshop will present the latest research and technologies to tackle these issues and share innovative strategies for mitigating health risks from heavy metals and emerging pollutants.
