Abiotic, biotic, and anthropogenic factors influencing fungal presence in groundwater, surface water, tap water, and non-mineral bottled water, with a possible effect of fungi on human health via different exposure points. The most common factors having an influence on the fungal presence and diversity in different water sources are divided into factors influencing fungal presence, mainly in raw water sources in the natural environment (indicated with green colour), anthropogenic factors influencing fungal presence during the production of tap and non-mineral bottled water, and exposure points of fungi via water-related activities (indicated with blue colour). Red colour indicates the most frequently detected fungal genera from tap and bottled water with their possible effects on human health. Reproduced from [6], open access and with authors’ permission.
