Abstract
This study estimated the exposure to dust mites in various occupational environments in Croatia. In total, 29 occupational dust samples were collected: 10 from urban areas (offices, archive of an insurance company, tobacco, paper-recycling, fish-processing and textile plants, animal unit for experimental rats, winery), nine from rural areas (barley, hay, animal food and flour warehouses, tailor’s shops, wood processing plant, swine confinement house, grocer’s storeroom), and 10 samples from cabins of five fishing boats (five floor and five bed samples). Mites were microscopically identified, and the levels of Der p 1, Der f 1, and Der 2 allergens measured using the DUSTSCREENTM test (Heska AG, Switzerland). Microscopy showed no mites in urban areas. Pyroglyphid mites (D. pteronyssinus) were found in all bed samples from fishing boats. Non-pyroglyphid mites were found in samples taken from barley, hay and animal food warehouses, the swine confinement house, grocer’s storeroom, and fishing boats. Pyroglyphid mite allergens were detected in eight of 10 dust samples from the fishing boats. Median levels of Der p 1, Der f 1, and Der 2 in cabin bed samples were 10 μg g-1, 0.2 μg g-1, and 3.5 μg g-1, respectively. Our findings on fishing boats suggests that pyroglyphid mites could be considered work-related allergens for fishermen. The results of this study confirmed non-pyroglyphid mites as occupational risk factors in various rural environments.
