Welcome from the Chairs
Dear colleagues,
On behalf of the MDPI journal Toxics (ISSN: 2305-6304; Impact Factor: 3.9) and its Scientific Committee, I am pleased to invite you to participate in the 2nd International Online Conference on Toxics. This meeting will be held online from 8-10 September 2025.
The aim of this platform is to bring together students, researchers, and scientists from around the world to present their work and exchange ideas on the exposure, effects, and risks regarding chemicals and materials in terms of humans and the natural environment, as well as on the development of new approaches to assess and/or manage the toxicological and ecotoxicological risks of chemicals and materials. The topics are organized into six sessions, corresponding to the following journal sections:
1. Exposure Pathways – Air and Water Contamination;
2. Molecular Stressors – Nanoparticles, Mixtures, and Persistent Pollutants;
3. Cutting-Edge Approaches in Pharmacology and Toxicology;
4. Pesticides, Pollutants, and Health Risk;
5. Exploring Non-Model Species for Ecotoxicology;
6. Bridging Science and Policy – New and Upcoming Regulations.
Submitted abstracts will be reviewed by the conference committee and, if accepted, authors can choose to submit proceedings papers or posters, potentially alongside a PowerPoint and/or video presentation of their work. All accepted abstracts will be published as one dedicated volume in the Proceedings journal (ISSN: 2504-3900).
The 2nd International Online Conference on Toxics offers you the opportunity to participate in this international, scholarly conference without having the concern or expenditure of travel fees. We would like to invite you to “attend” this conference by presenting your latest work. Abstracts (in English) should be submitted online before 9th May 2025.

Dr. Bauer is an associate professor in Department of Environmental & Occupational Health (EOH) at the Colorado School of Public Health. She is interested in how environmental and occupational exposures to toxicants contribute to human lung diseases, particularly asthma, chronic obstructive pulmonary disease, and cancer. The focus of her research is on determining the molecular mechanisms driving these diseases, and use these mechanistic insights to predict disease incidence, and develop preventive and interventive strategies for improving outcomes in human health. Prior to coming to Colorado, she was a faculty member in the Department of Pathobiology and Center for Integrative Toxicology at Michigan State University. She has a strong background in environmental toxicology, pharmacology, and environmental genetics through training at the University of Colorado Health Sciences (UCHSC), CIIT Centers for Health Research, and the National Institute for Environmental Health Sciences (NIEHS).

Comparing single species responses to community responses in mesocosms, using in situ, ex situ, and receiving water toxicity tests
Jim Lazorchak is the Editor of Chemosphere. Adjunct Professor at the University of Cincinnati and Thomas More University. My research in my early career centered on developing fish, invertebrate, and plant bioassessment and ecotoxicology methods to assess the biological integrity of lakes, streams, rivers, and estuaries. Current research is on the use of biological indicators (sediment toxicity, biotic condition, invertebrate, and fish tissue contamination) to assess effectiveness of various remedies to reduce legacy contaminants in sediments and restoration of habitats of our Great Lakes Areas of Concern (AOCs). Also generating ecotoxicity information on cyanotoxins, microplastics, PFAS-free Aqueous Film-Forming-Foams (AFFFs), and Pharmaceuticals. Standardizing of new ecotoxicity test methods for use in assessing mixtures, whole effluent toxicity, and surface waters. Daphnia magna short-term growth method, Lampsilis siliquoidea (fatmucket), Neocloeon triangulifer (mayfly), and Oncorhynchus mykiss (Rainbow trout).
Invited Speakers
transport and transformation of pollutants; remediation of contaminated soil and ground-water; effects of pollutants on microorganisms; effects of pollutants on human beings
Unseen Threats: The Hidden Impacts of Pollutants on Marine Megafauna
Dr Sara Novais research focuses on the ecology, physiology, and stress responses of marine organisms, particularly top predators such as sharks, seabirds, sea turtles, and cetaceans. Using molecular and biochemical tools, she investigates the impacts of global change—especially pollution and climate change—on marine life. The main goal of her research is to provide insights that enhance conservation strategies, promoting ecosystem resilience, and contributing to the sustainable management of marine environments.

Any financial support for the study must be fully disclosed in the "Acknowledgments" section.
MDPI, the publisher of the Sciforum.net platform, is an open access publisher. We believe authors should retain the copyright to their scholarly works. Hence, by submitting an abstract to this conference, you retain the copyright to the work, but you grant MDPI the non-exclusive right to publish this abstract online on the Sciforum.net platform. This means you can easily submit your full paper (with the abstract) to any scientific journal at a later stage and transfer the copyright to its publisher if required.
