Abstract

Naturally occurring radionuclides in soil, water, and plants, including spices, pose potential health risks. Given the widespread use of spices in culinary practices, it is crucial to assess the potential health risks associated with their natural radionuclides content. This study determines the activity concentrations of natural radionuclides in locally processed and imported spices from markets in Delta and Ogun States, Nigeria, using gamma spectrometry. Monte Carlo simulations estimated the probabilistic distribution of cancer risk over a lifetime of exposure. The results revealed significant variability in the activity concentrations of 40K, 226Ra, and 232Th among the spice samples. The mean committed effective doses due to ingestion were 10.56 µSv/y, 9.82 µSv/y, and 6.87 µSv/y for locally produced and imported spices, respectively. Both deterministic and probabilistic analyses show that the cancer risk values fall within the acceptable range of 10-6 to 10-4, indicating minimal risk from ingestion of natural radionuclides in spices.

期刊介绍: International Journal of Environmental Health Research ( IJEHR ) is devoted to the rapid publication of research in environmental health, acting as a link between the diverse research communities and practitioners in environmental health. Published articles encompass original research papers, technical notes and review articles. IJEHR publishes articles on all aspects of the interaction between the environment and human health. This interaction can broadly be divided into three areas: the natural environment and health – health implications and monitoring of air, water and soil pollutants and pollution and health improvements and air, water and soil quality standards; the built environment and health – occupational health and safety, exposure limits, monitoring and control of pollutants in the workplace, and standards of health; and communicable diseases – disease spread, control and prevention, food hygiene and control, and health aspects of rodents and insects. IJEHR is published in association with the International Federation of Environmental Health and includes news from the Federation of international meetings, courses and environmental health issues.
