: Coastal environments and its species are exposed to multiple stressors including both natural and anthropogenic. Temperature warming and pollutants pre-exposure represents a potentially additive risk in mussel?s intertidal populations. The aim of this study was evaluate three low-cost responses; Mortality rate (MR), Condition index (CI) and Stress Over Stress (SOS) in mussels from coastal areas from Buenos Aires province, Argentina, with different anthropogenic impact (Port, Estuary and Control). The mussels (Brachidontes rodriguezii) from different areas were exposed at different Temperatures (Tº) ranging from 10 to 30ºC at 14 days. Mussels from Port area showed high MR and decreased CI at 22, 26 and 30ºC compared to mussels from estuarine and control areas (p
