Chemistry of the Transformation and Degradation of Biological Contaminants in the Environment
Organizing Division: ENVR
Biological contaminants including a broad range of pathogens, antibiotic-resistant genes (ARGs), algae and algal toxins, mycotoxins, allergens, RNA interference (RNAi) biopesticides, and prions are widespread in natural and built environments, posing substantial risks to human health and ecosystems. However, due to their complex structures and chemistries, the transformation, degradation, and inactivation pathways of these contaminants in chemical processes are largely understudied. For instance, although pathogen disinfection has been widely explored, the chemical cues driving the transformation and degradation of biological molecules within pathogens and their relationship to pathogen inactivation are not well understood. Additionally, how biological contaminants interact with disinfectants to form disinfection byproducts (DBPs) remains elusive. This symposium invites submissions that examine the chemical pathways and mechanisms involved in the transformation and degradation of biological contaminants in the environment, including but not limited to: Pathogen disinfection and chemical damage to biomolecules; Chemical transformation and degradation of biological contaminants in natural and engineered systems; Production of DBPs through chemical reactions with biological contaminants; Correlations between the damage to biological contaminants and the resulting loss of function and activity.

In Silico Methods for Optimizing ADME and Human Dose Prediction: In Silico Methods for Optimizing ADME and Human Dose Prediction
Organizing Division: MEDI
This session aims to spotlight silico methods to optimize ADME & human dose prediction (HDP). Over the last two decades, Lipinski's rules and efficiency metrics (e.g. Lipophillic Ligand Efficiency, LLE and Metabolic Ligand Efficiency, MetLipE) revolutionized the way medicinal chemists approach ADME optimization. The next generation of predictive methods seeks to further advance medicinal chemistry by using machine learning models to predict multiple paramaters such as oral availability, clearance, distribution, and HDP. The goal of this session is to inform the MEDI community about these emerging tools, particularly those that promise a practical solution to the medicinal chemists needs

Green, Low-Carbon and Resource Utilization Treatment Technology for Wastewater, Solid Waste, and Contaminated Sites of Petrochemical Industry: Green, Low-Carbon and Resource Utilization Treatment Technology for Wastewater, Solid Waste, and Contaminated Sites of Petrochemical Industry
Organizing Divisions: ENFL, ENVR
To address the increasingly strict environmental regulations and carbon emission restrictions during the transformation and development of the petrochemical industry, the establishment of environmental technology innovation chain is necessary. However, the problems of secondary pollution, high carbon emission and the waste of resources often impede the applications of these technologies. To achieve the high-level protection of the ecological environment, this symposium will focus on the green, low-carbon and resource utilization treatment technology for wastewater, solid waste (e.g. sludge, waste catalysts, waste plastics and petroleum/coal-based ash), and contaminated sites in the petrochemical industry. The symposium aims to provide a platform for sharing the achievements of scientific research, understanding the trends of technological development, broadening research ideas, and promoting the commercialization of achievements. It will also enhance the support of environmental protection technology for carbon reduction, pollution control, waste resource utilization and circular economy in the petrochemical industry. Additionally, we will explore the innovation model of pollution and synergistical carbon reduction in the symposium.

Advances in PFAS Research and Outlook
Organizing Division: ENVR
Per-and polyfluoroalkyl substances (PFAS) are manmade chemicals and have been widely used since their development in 1940s. These synthetic compounds are resistant to degradation due to the presence of carbon-fluorine (C-F) bonds and are nicknamed as forever chemicals. PFAS have been also used in military within aqueous film forming foams (AFFF) for fire training and emergency response purposes. It is estimated that around 110 million Americans find PFAS contamination in their drinking water supplies. Exposure of PFAS including their short-chain cousins has been linked to several health-related issues such as cancer, elevated cholesterol, obesity in humans. The U.S. Environmental Protection Agency (EPA) finalized critical rule to designate perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) as hazardous substances under CERCLA. Moreover, EPA also established enforceable limit of presence of certain PFAS compounds in the drinking water. Various traditional techniques have been attempted to degrade and remove PFAS from contaminated media. The incineration of PFAS with other wastes have potential to produce the active greenhouse gases. This symposium will discuss recent advances in research efforts on the degradation, destruction, detection, isolation, removal, and sensing of PFAS. Moreover, research on fluorine free PFAS alternatives and toxic effects of PFAS will also be discussed.
