IN SCIENTIA FIDIMUS
Andrey Korchevskiy, Ph.D., DABT, CIH –
Director of Research and Development at C&IH, Inc., certified toxicologist and industrial hygienist, mathematician, and expert in Elizabethan theatre (translator of Shakespeare, Ford, Webster).
In Scientia Fidimus – “In Science We Trust” – is the slogan I chose for this personal web-site. I want this site to be the information source for everyone who supports the idea of science being the basis for decision-making in the areas of public health, toxicology, social development, information technologies, and others.
In our times when conspiratorial theories tend to replace the high air of solid research and chaotic social media substitutes the silence of libraries, the interests of each healthy or sick person, of workers and communities, of the young and older generations, is in promoting best principles of scientific analysis, mathematical modeling, and powerful tools of human health risk assessment.
Andrey Korchevskiy will present a session on elongate mineral particles at 38th Annual General Meeting of the Canadian Registration Board of Occupational Hygienists
Andrey Korchevskiy will present a session “Asbestos and Other Elongate Mineral Particles: How Toxicology Makes Risk Assessment Possible” for 38th Annual General Meeting of the Canadian Registration Board of Occupational Hygienists on June 12, 2025, 3:00 pm (EST).
Asbestos has been studied by toxicologists for many decades. Amazingly, there are still more questions than answers. Why does asbestiform fibers cause mesothelioma in humans, but non-fibrous dust does not? Are various mineral types and sizes of elongate particles identical from toxicological standpoints? Is there a threshold for asbestos exposure for producing cancer in humans? How applicable is historical epidemiological evidence for current risk assessment purposes? Andrey Korchevskiy, the leading editor of the recently published book “Health Risk Assessment for Asbestos and Other Fibrous Minerals”, will address the most recent advances in several research areas related to health effects of elongate mineral particles. The presentation will attempt to guide the audience through the content of relevant ongoing studies on these topics, demonstrating the progress achieved and outlining future needs in research and actions. Time for discussion will be allocated.
A group of leading scientists submitted a letter to the FDA commissioner, Dr. Martin Makary, regarding the agency’s recent panel meeting on talc
The letter to US FDA by a group of leading scientists and medical doctors, representing various areas of knowledge, including mineralogy, geology, toxicology, pathology, epidemiology, risk assessment, molecular biology, oncology, and others, was submitted on June 9, 2025. Many signatories studied talc safety for years or have significant experience in evaluating mineral particles and assessing their health effects. The group also includes medical professionals who have long treated patients in the field of gynecologic oncology and different types of malignancies, as well as have performed in-depth research on the etiology of gastrointestinal cancers. The letter argues that the recent panel meeting on talc safety by FDA that was held on May 20, 2025 lacked transparency and proper participation of experts from various scientific areas. In particular, it is emphasized in the letter that there is no scientific evidence for carcinogenicity of pure talc. FDA should provide scientifically based risk assessment for various applications of talc and take actions only based on sound scientific information. The letter calls for true discussion and public input on this important subject.
