The composition and distribution of airborne particles in different locations in a salt mine were determined in terms of their origin, the distance from the air inlet, and the adaptation of post-mining chambers and corridors for tourists and general audience. The composition of aerosols in air was also evaluated from the perspective of human health. Air samples were collected on filters by using portable air pumps, in a historical underground salt mine in Bochnia (Poland), which is currently a touristic and recreation attraction and sanatorium. The particulate matter (PM) concentration was determined using the gravimetric method by weighing quartz filters. The content of carbon, water-soluble constituents, trace elements, and minerals was also determined. A genetic classification of the suspended matter was proposed and comprised three groups: geogenic (fragments of rock salt and associated minerals from the deposit), anthropogenic (carbon-bearing particles from tourist traffic and small amounts of fly ash, soot, and rust), and biogenic particles (occasional pollen). The total PM concentration in air varied between 21 and 79 μg/m³ (with PM₄ constituting 4–24 μg/m³). The amount of atmospheric dust components coming from the surface was low and decreased with the distance from the intake shaft, thus indicating the self-cleaning process. NaCl dominated the water-soluble constituents, while Fe, Al, Ag, Mn, and Zn dominated the trace elements, with the concentration of majority of them below 30 ng/m³. These metals are released into air from both natural sources and the wear or/and corrosion of mining and tourists facilities in the underground functional space. No potentially toxic elements or constituents were detected. The presence of salt particles and salty spray in the atmosphere of salt mine, which may have anti-inflammatory and antiallergic properties, is beneficial to human health. This study will allow for a broader look at the potential of halotherapy in underground salt mines from a medical and regulatory point of view.

盐矿中不同位置的空气悬浮颗粒的组成和分布是根据它们的来源、与进气口的距离以及对游客和普通观众的采后室和走廊的适应性来确定的。空气中气溶胶的成分也从人体健康的角度进行了评价。在波赫尼亚（波兰）一个历史悠久的地下盐矿中，使用便携式空气泵在过滤器上收集空气样本，该盐矿目前是一个旅游和休闲景点和疗养院。通过称重石英过滤器，使用重量法测定颗粒物 (PM) 浓度。还测定了碳、水溶性成分、微量元素和矿物质的含量。提出了悬浮物质的遗传分类，包括三组：地质（来自矿床的岩盐和相关矿物碎片）、人为（来自旅游交通的含碳颗粒和少量飞灰、煤烟和铁锈）和生物颗粒（偶尔出现的花粉）。空气中的总 PM 浓度在 21 和 79 μg/m 之间变化³（PM ₄构成 4–24 μg/m ³）。来自地表的大气粉尘成分含量较低，且随着距进气轴的距离而减少，从而表明自清洁过程。水溶性成分以NaCl为主，微量元素以Fe、Al、Ag、Mn、Zn为主，大部分浓度低于30 ng/m ³. 这些金属从自然资源以及地下功能空间中采矿和旅游设施的磨损或/和腐蚀释放到空气中。没有检测到潜在的有毒元素或成分。盐矿大气中的盐粒和盐雾的存在，可能具有抗炎和抗过敏的特性，对人体健康有益。这项研究将从医学和监管的角度更广泛地了解地下盐矿中卤疗法的潜力。
