A new article published in The Synergist explores how modern risk paradigms intersect with AIHA’s current content priorities and influence occupational and environmental health and safety practice. The article, titled “The Keystone: Risk Paradigms and AIHA Content Priorities,” examines how traditional and emerging risk frameworks align with the so-called “content priorities” – the directions of […]

A new study co-authored by C&IH advances the methodology of modeling exposure thresholds for asbestos-related mesothelioma, offering fresh insight into how different fiber types may exhibit distinct dose-response behaviors. The article, “Comparison of various methodological approaches to model asbestos thresholds for mesothelioma,” was published in 2025 in Frontiers in Public Health, by Dr. Julie Goodman […]

A peer-reviewed study co-authored by C&IH presents updated exposure estimates for the historic Québec chrysotile miner and miller cohort, offering new insight into risk assessment and threshold modeling for mesothelioma. The article, “Updates on exposure estimation for the Québec cohort of chrysotile miners and millers: implications for risk assessment and threshold hypothesis,” was published in […]

A new research paper by C&IH called “The Empirical Metric of Mesothelial Carcinogenicity for Carbon Nanotubes and Elongate Mineral Particles” was recently published by the journal Inhalation Toxicology. The article presents a comprehensive analysis of how the physical dimensions and biopersistence of elongate mineral particles (EMPs) and high aspect ratio nanomaterials (HARNs), such as carbon […]

The Journal Frontiers in Toxicology published a new study by C&IH titled “Critical values for dimensional parameters of mesotheliomagenic mineral fibers: evidence from the dimensions and rigidity of MWCNT.” The study investigates the relationship between the physical characteristics of mineral fibers and their potential to induce mesothelioma, a type of cancer associated with exposure to […]

A new research paper in Fronters in Public Health titled “The size distribution of nanoparticles emitted from advanced manufacturing devices impacts predicted carcinogenic potential” explores how nanoparticle emissions from modern manufacturing equipment, such as 3D printers, vary in size and how these size differences influence potential health risks. New data for particles size in 3D […]

Toxicology Reports has published a new research paper by C&IH, “Habit of Elongate Amphibole Particles as a Predictor of Mesothelial Carcinogenicity.”  Authored by C&IH Director of Research and Development, Dr. Andrey Korchevskiy along with C&IH Senior Scientific Advisor and Professor Emerita of the University of Maryland, Dr. Ann Wylie, the paper is currently available online […]

The first edition book, published by John Wiley & Sons, evaluates the risks and human health impacts of asbestos and other fibrous minerals.  The book was prepared by C&IH Director of Research and Development, Andrey Korchevskiy along with C&IH Founder and Senior Scientist, James Rasmuson and C&IH President and CEO, Eric Rasmuson. From the book’s […]

The American Conference of Governmental Industrial Hygienists (ACGIH) recently published a second edition of “Bioaerosols: Assessment and Control Revised.”  Authored by the ACGIH Bioaerosols Committee, the revised publication serves as a comprehensive guide in the assessment and control of bioaerosols in the workplace and includes contributions from scientists with public, academic, and professional backgrounds.  C&IH […]

The Environmental Research Journal published a paper titled, “Excitable Systems: A New Perspective on the Cellular Impact of Elongate Mineral Particles” which included contributions from C&IH Director of Research and Development, Dr. Andrey Korchevskiy.  The paper investigates how the geometry of elongate mineral particles (EMPs) in contact with cells influences esotaxis, a recently discovered mechanism […]

Included in the January 2023 edition of The Synergist, published by the AIHA, is an article by C&IH Director of Research and Development, Dr. Andrey Korchevskiy titled: “The Safety Threshold: Understanding Risk Tolerances.” The article explores how the perceived acceptability of a hazard drives risk tolerance and determines “safety thresholds” among individuals and groups. Risk […]

The journal of Current Research in Toxicology published in its Volume 2, 2021 issue a letter to the editor by Dr. Ann Wylie of the University of Maryland and Dr. Andrey Korchevskiy of C&IH titled, “Carcinogenicity of Fibrous Glaucophane: How Should We Fill the Data Gaps?”  The letter discusses: Modeling approaches that should be applied […]
