We are pleased to present this special issue featuring articles presented at the National Conference on Environmental Toxicology: Impact on Human Health (Environ Tox 2021), held on 25th–26th November 2021 at Vivekananda Global University, Jaipur, Rajasthan, India. The conference aimed to raise awareness about the changing environment with reference to human health. Environ Tox 2021 was a highly anticipated event that brought together experts from various fields and provided a platform for eminent scientists, researchers, and students to discuss current issues related to environmental health. The conference emphasized the need for a multidisciplinary approach to address the challenges of environmental toxicity and its impact on human health. This special issue intends to disseminate knowledge further and exchange ideas among academicians, scientists, and industry professionals. The conference covered a wide range of topics, including exposure assessment, environmental monitoring, biomonitoring, risk assessment, and management of environmental toxins. The experts discussed the latest research on the impact of toxins on human health and explored new approaches to mitigate the risks associated with environmental toxicity.

As we reflect on the discussions and insights shared at the recent conference to create a more sustainable future, it is clear that the theme of hazardous chemical exposure and its impact on animals, humans, and the environment were at the forefront of many of the discussions. The conference covered a broad range of topics, including environmental impact assessment, food and agricultural toxicology, bioremediation approaches, and environmental regulation, all of which are essential to achieving a more sustainable future. One of the key takeaways from the conference was the importance of adopting a system-thinking approach to addressing these complex and interconnected issues. Therefore, solutions to environmental problems require an understanding of the interdependencies between these components and the need for a holistic approach to address the root causes of environmental degradation. Another important topic that was discussed at the conference was the role of environmental forensic toxicology in identifying the sources and causes of pollution. Environmental forensic toxicology is a valuable tool in determining the environmental impact of hazardous chemicals and can aid in developing effective abatement methods and environmental regulation. In addition to these discussions, the conference covered a wide range of topics related to environmental sustainability, including global warming, green chemistry, natural hazards and disaster management, environmental protection, epidemiology, and biostatistics, among others. These discussions highlight the importance of adopting a multi-disciplinary approach to address environmental problems and the need for collaboration between scientists, policymakers, and stakeholders to develop effective solutions.

Overall, the National Conference on Environmental Toxicology: Impact on Human Health (Environ Tox 2021) was a successful event that brought together experts from various fields to discuss the challenges of environmental toxicity and its impact on human health. The conference provided a platform for researchers, policymakers, and industry leaders to share their knowledge and expertise and explore new approaches to mitigate the risks associated with environmental toxins. The conference was a great success, with 15 invited speakers and 200 participants from different geographical regions of India covering every aspect of Environmental Toxicology. We are deeply indebted to the numerous reviewers for the detailed review of the papers, and we thank all the contributing authors for their valuable contributions. We also appreciate the time-to-time assistance provided by the entire editorial, publishing, and production teams of Environmental Science and Pollution Research (ESPR) for their considerable efforts in bringing out this special issue. The conference provided an excellent platform for sharing knowledge and ideas, promoting collaboration, and fostering a greater understanding of the complex interdependencies that underlie environmental problems.

We hope that this special issue on Environmental Toxicology: Impact on Human Health provides valuable insights to the researchers working in nanobiotechnology. We firmly believe that this special issue will be of immense value to researchers, academicians, and professionals working in the field of Environmental Toxicology. Once again, we thank all the contributors, reviewers, and publishers for their significant contributions to the success of the conference and this special issue. It is our hope that the discussions and insights shared at this conference will inspire continued efforts to address environmental challenges and lead to the development of effective solutions that will enable us to create a more sustainable and resilient future.
