“…Therefore, the problem of occupational asbestos exposure should not be ignored in either developed (Han et al 2022 ) or developing countries (Chen et al 2019 ). Many scholars have discovered methods of classifying (Lee et al 2024 ) and harmlessly disposing (Capitani et al 2024 ) of asbestos, which has helped to reduce exposure to asbestos.…”

Malignant mesothelioma, a rare and aggressive cancer primarily caused by occupational asbestos exposure, has a poor prognosis. This study leverages the Global Burden of Disease (GBD) 2019 dataset to analyze the burden of mesothelioma linked to occupational asbestos exposure from 1990 to 2019. The analysis includes the number of mesothelioma deaths and disability-adjusted life years (DALYs) attributable to occupational asbestos exposure, focusing on trends in age-standardized mortality rate (ASMR) and age-standardized disability-adjusted life-year rate (ASDR) by year, age, sex, country, region, and Socio-demographic Index (SDI). In 2019, 91.7% of mesothelioma deaths and 85.2% of DALYs were attributable to occupational asbestos exposure, resulting in 26,820 (95% UI 24,312–28,622) deaths and 569,429 (95% UI 509,956–617,484) DALYs. Despite a decline in ASMR and ASDR from 1990 to 2019, the absolute number of deaths and DALYs almost doubled. The United States reported the highest number of mesothelioma deaths, while China had the highest number of DALYs. Age-specific mortality rates and DALYs decreased in the 25–74 age group but increased in the 75+ age group. In conclusion, occupational asbestos exposure remains the primary cause of mesothelioma worldwide, with an increasing number of deaths and DALYs. The highest incidence rates are observed in high-income areas, and rates are rising in low-income areas. It is crucial to raise awareness about the hazards of asbestos to reduce the global burden of mesothelioma linked to occupational exposure.

The study examined building materials containing asbestos, which have been considered hazardous waste for several years. Samples were taken from various places in Poland. The chemical composition was examined using chemical analysis, the mineralogical phases were identified using X-ray diffraction, and the structure was identified using scanning electron microscopy, taking into account energy-dispersive spectroscopy. Thermal tests of the samples were performed using thermal analysis, thermogravimetric measurements and high-temperature microscopy. Additionally, changes that occurred in the microstructure were determined using mercury porosimetry and infrared spectroscopy. All the above research methods were used to characterise the properties of cement–asbestos materials, which were also subjected to isothermal thermal treatment at a temperature of 1100 °C for 4 h. The results proved that the material after thermal treatment undergoes significant structural changes. The thermal decomposition process of cement–asbestos involves dehydration, dehydroxylation and then recrystallisation to new stable crystalline phases but in the context of asbestos, we are dealing here with the so-called phenomenon of pseudomorphosis. Knowledge about the thermal properties of asbestos materials can provide us with data on how the material undergoes significant structural changes, thanks to which it will be possible to use neutralised cement–asbestos waste as possible safe materials.
