abstract = {Although the presence of potentially toxic metals in soils is normally associated with
human soil pollution, these elements also appear naturally in environments in which the lithological
base contains ultramafic rocks such as peridotites. Serpentinitic soils tend to develop on substrates
of this kind, often containing metals with few or no known biological functions, which in some
cases are toxic for most plants. This study assessed the level of potentially toxic metals and other
elements in an endorheic basin discovered in Sierra Bermeja (Southern Spain), one of the largest
peridotite outcrops on Earth. In this location—of particular interest given that basins of this kind
are very rare on peridotites—six geomorphoedaphic sub-units on three different substrates were
identified. The distribution of microelements in these sub-units was analyzed, and stratified random
sampling was performed to identify the major ions with essential functions for living organisms and
the potentially toxic metals. The lowest values for macronutrients appeared in the soils formed on
ultramafic materials. When analyzing the load of potentially toxic metals, no significant differences
were detected between the soils formed on serpentinite and peridotite substrates, although different
values were obtained in the soils formed over acidic rocks.},
