| Abstract |
The need to carry out monitoring programs for environmental pollution of coastal ecosystems makes it necessary to increase the number of indicator species in order to have a wide range of suitable organisms for most of the possible toxic substances and ways of exposure. With the purpose of analyzing the suitability of limpets (Patella spp.) for their use in biomonitoring programs, a literature review was performed on 88 cases found in the Web of Science online platform. The capacity of limpets to accumulate metals and hydrocarbons has been examined in several field studies. In most cases there is a clear relationship between body content of a pollutant in soft tissues of limpets and the corresponding environmental level. Likewise, different responses to pollutants have been reported in limpets, including induction of DNA damage, induction of metallothioneins, oxidative stress, decrease of Neutral Red retention or variations in heart rate. Regarding the study of changes in community structure, an uneven response to disturbances (e.g. oil spills, wastewater discharge) by species of the genus Patella has been documented. Moreover, generally limpets respond to pollutants similarly to, or even more effectively than, mussels; therefore, their inclusion as sentinel organisms in regional monitoring plans seems appropriate. |
