Article Synopsis
- Multiple human-induced stressors, like ocean acidification and shading from infrastructure, can significantly affect marine organisms, particularly in coastal areas.
- A study on hermit crabs exposed to reduced pH and darkness revealed that both stressors increased mortality, while growth was negatively influenced by the combination of stressors.
- Interestingly, while crabs maintained calcification levels despite lower pH, shading affected their behavior towards predator and resource signals, highlighting the complex interaction between local disturbances and global environmental changes.
Evaluation of polycyclic aromatic hydrocarbons bioavailability on Santos Bay (Brazil) through levels of biliary metabolites.
Mar Pollut Bull
April 2018
This study evaluated the PAH bioavailability from Santos Bay (Brazil) in 4 species of fish, using PAH biliary metabolites. The collection was done monthly, between July and December, in three different regions of Santos Bay. The metabolites were analyzed through a high performance liquid chromatograph with fluorescence detectors.

Fish biliary metabolites from low-contaminated (Cananéia) and contaminated (Santos) Brazilian estuaries were analysed using a high-performance liquid chromatography apparatus coupled to fluorescence detectors connected in a series. In the Cananéia and Santos estuaries, total metabolite levels ranged from 0.
