Occupational Health Sciences Overview

Principles

Definition

Occupational health sciences is a multidisciplinary field concerned with the safety, health, and well-being of individuals in the workplace. It investigates the interaction between work environments and human health, utilizing principles from disciplines such as medicine, epidemiology, psychology, and ergonomics to identify, assess, prevent, and control work-related hazards and adapt work to human capabilities, thereby aiming to prevent occupational illnesses and injuries.

Foundations of Exposure Science era

Alice Hamilton, renowned for hazard recognition and advocacy for workplace hygiene, exemplifies the foundational risk awareness that shaped mid-century exposure science. H. Grandjean advanced the era's practical core by promoting standardized industrial hygiene methods and translating environmental measurements into actionable exposure estimates. Other contemporaries in industrial hygiene and occupational medicine developed numeric exposure limits, sampling standards, and early biomonitoring concepts, and regulatory bodies adopted these measurement-driven frameworks. Together these figures anchored a measurement and surveillance paradigm that connected toxicology, surveillance, and workplace standards to support later epidemiology and risk assessment.

Standardized Risk Assessment era

Gary M. Shaw [1] is associated with leading epidemiology work during this era, with affiliations at the University of California, San Francisco [3] and Stanford University [4]. His key contribution in this era includes pioneering quantitative assessment of maternal pesticide exposure from multiple sources, as illustrated by the paper Maternal Pesticide Exposure from Multiple Sources and Selected Congenital Anomalies [7], which advanced exposure characterization and causal inference for regulatory risk assessment. Gary W. Hunninghake [2] is associated with Johns Hopkins University [5] and the University of Pennsylvania [6], reflecting his collaborative roles during this era. His 2004 case-control etiologic study of sarcoidosis [8] exemplified etiologic design in standardized risk assessment and informed the identification of environmental and occupational risk factors relevant to this era.

Global Exposome Integration era

Cengiz Kahraman [1] is a scholar whose work across Istanbul Technical University [2] and Karadeniz Technical University [3] in the Global Exposome Integration era (2010-2023) informs occupational health sciences. His key contribution, documented in the 2017 paper A novel approach to risk assessment for occupational health and safety using Pythagorean fuzzy AHP & fuzzy inference system [4], provides an uncertainty-aware framework for risk assessment in occupational settings and demonstrates how multi-criteria fuzzy methods can synthesize diverse exposures for prioritized prevention. By applying Pythagorean fuzzy AHP [4] and a fuzzy inference system in this context, Kahraman illustrates a scalable tool for integrated exposure–response estimation, a core aim of the exposome-informed era. The author’s ongoing work at Istanbul Technical University [2] and Karadeniz Technical University [3], as reflected in A novel approach to risk assessment for occupational health and safety using Pythagorean fuzzy AHP & fuzzy inference system [4], demonstrates the period’s shift toward uncertainty-aware, cross-domain risk prioritization in occupational health.
