Background: The aim of this paper is to present a concise but comprehensive information on the occurrence of carcinogenic or mutagenic agents in Polish enterprises and the number of workers exposed to those agents reported to the central register by employers. Objectives and responsibilities of the register, as well as the range and methods of data gathering are discussed.
Material And Methods: Data concerning carcinogenic or mutagenic chemical substances and technological processes reported to central register in 2008-2010 were analyzed.
Results: In 2008-2010 more than 300 carcinogenic or mutagenic chemical substances were reported to the register. Approximately 2500 plants reported above 150 000 per-person-exposures annually. Among all technological processes regarded as occupational carcinogens, hardwood dusts exposure (about 660 companies; 11 000-13 000 exposed workers each year) and exposure to polycyclic aromatic hydrocarbons (PAHs) present in coal products (117-125 plantsl 3000 exposed per year) were reported.
Conclusions: The most widespread carcinogenic/mutagenic substances were: benzene, chromium(VI) compounds: potassium dichromate and chromate, chromium(VI) trioxide and other chromium compounds, ethylene oxide, asbestos, benzo[a]pyrene and gasoline. The highest number of men was exposed to particular PAHs and benzene, and the majority of women was exposed to benzene, potassium dichromate and chromate, acrylamide, ethylene oxide and gasoline. The lack of clear-cut definition of occupational exposure to carcinogen creates a problem faced by employers in defining the accurate number of exposed workers.

With the rapid industrialization and urbanization of coastal areas, marine pollution (such as heavy metals) is increasingly contaminating the environment, posing significant public health risks. Eastern Guangdong, a key aquaculture and fisheries hub in China, has a growing market for aquatic products. Heavy metals persist in the environment and are difficult to degrade and bioaccumulate in marine organisms through the food web, presenting carcinogenic and mutagenic risks to humans, as top predators.

The objective of this study is to investigate the potential mutagenic effects of the exposure of mice to aerosols produced from the component liquids of an electronic nicotine delivery system (ENDS). The use of electronic cigarettes (e-cigs) and ENDSs has increased tremendously over the past two decades. From what we know to date, ENDSs contain much lower levels of known carcinogens than tobacco smoke.

Article Synopsis
- Gene expression biomarkers can help identify both genotoxic and non-genotoxic carcinogens, which could reduce the need for animal testing.
- In August 2022, a workshop reviewed current methods for using transcriptomic profiling to detect genotoxic chemicals, examining 1341 papers to find reliable biomarkers.
- The analysis identified two promising in vivo biomarkers and three in vitro biomarkers that show over 92% predictive accuracy and can be adapted for various testing conditions, with support from workshop participants for their regulatory adoption.
