“…The indoor asbestos concentration was found to be higher than the standard level, corresponding to 0.1 f/ml, and the outdoor reached values of 2.57 f/ml, mainly due to the exposition of asbestos-containing white soils (Bolan et al 2023 ). Indeed, the annual survey of the US Geological about asbestos consumption data reports that a total of 111,123 tons, corresponding to 11,112 tons per year, of asbestos were consumed in Turkey between 1999 and 2009 (Stayner et al 2013 ).…”

This study delves into the repercussions of the 2023 earthquake in Turkey, particularity its impact on air pollution. A year post-event, it is evident that scientific literature has paid limited attention to monitoring the situation. However, the release of hazardous substances, such as asbestos, lead, and other toxins, from damaged structures poses a significant threat by contaminating nearby air, soil, and water sources, thereby jeopardizing ecosystems and public well-being. The improper disposal of waste post-earthquake and the presence of mining and oil refinery sites in the region contribute to potential air pollutants. These circumstances create challenging environments conducive to the spread of respiratory diseases, with potential long-term health and social consequences. Unfortunately, existing data gaps hinder a comprehensive understanding of the situation. This paper pioneers the reporting and analysis of data regarding potential sources of air pollution resulting from the earthquake in Turkey. It also pinpoints gaps in knowledge, outlining areas that demand further investigation. To effectively prevent and mitigate air pollution risks and associated health concerns linked to earthquakes, strategic recommendations are proposed. A key suggestion is the establishment of post-disaster air pollution monitoring systems capable of swiftly identifying emerging health issues, facilitating efficient responses, and curtailing potential long-term effects of the disaster. The paper underscores the necessity for continuous health monitoring of the affected population to mitigate possible adverse impacts on human health. These strategies play a pivotal role in reducing the likelihood of air pollution, supporting emergency response and recovery initiatives, and fostering new dedicated scientific studies.

“…Here, the samples would have been sorted out despite wrong classification. This applies only to a limited extent to the false negative distance tube samples (0.73 %, 17), some of which have been incorrectly classified as asbestos-containing (8) and some of which have been classified as asbestos-free (9). Out of the false negatives of the spacers cast in concrete (0.33 %, 8), all samples were predicted as in-situ concrete, i.e., asbestos-free.…”

“…Asbestos treatment technologies focus either on stabilization, i.e., reduction of fiber release or on alteration of the fiber structure [8]. In asbestos stabilization, the ACM are mixed with cement materials and water, resulting in the capture of toxic components within the waste matrix [9]. Fiber alteration can either be achieved by application of thermal or mechanical energy, such as vitrification or highenergy milling.…”

The feasibility to discriminate potentially asbestos‐containing components from asbestos‐free concrete based on camera images using the example of wall demolition waste is investigated. For this, three types of asbestos substitute materials and two types of concrete are crushed and photographed. The classification of the fragment images is carried out with a) morphological and texture features and b) with features automatically extracted by the pretrained MobileNetV3 network. Feret diameters, circularity, and others served as morphological descriptors. The texture was described by measures of grey‐level intensity, as obtained from the grey‐level co‐occurrence matrix. Support vector machines are found to achieve classification accuracies above 99 % based on the automatically extracted features. The presented identification approach is promising to automate the treatment process of asbestos‐containing materials from construction and demolition waste, which is effortful and requires expert knowledge to this day.

“…Among the roofs selected in the field, those that showed the presence of asbestos to PLM, were assessed in field to define their state of deterioration, discriminating between High Intervention Priority (HIP) and Low Intervention Priority (LIP) [ 14 ]. These priority levels refer to the need or not to urgently intervene in the asbestos-cement roofs, either through radical measures such as the removal of AC, or through mitigation methods such as enclosure or encapsulation [ [28] , [29] , [30] , [31] , [32] ]. The method used in the field to differentiate between HIP and LIP is the traditional method of visual qualitative inspection [ 33 , 34 ].…”
