The ocean is the main receptor environment for POPs (Dachs et al., 2002), and these compounds may attain dangerous concentration levels in marine organisms because of bioaccumulation and biomagnification processes in food webs, especially concerning the top predators, including marine mammals. With ...

Antioxidants are chemical substances that, while found in low doses compared to that of an oxygen electrode, can delay or prevent oxidation [16]. Antioxidants are the body’s natural first line of defense against dangerous chemicals identified as free radicals, and they must respond quickly to ...
Therefore, the shelf life of VOs depends on their oxidative stability [35,36]. Moreover, it is remarkable that throughout the oxidation process, some toxic compounds, such as reactive carbonyl compounds can result in advanced lipid peroxidation end products. These are possibly dangerous to human ...
CAUTION! HF is a potentially dangerous chemical and should be handled with the proper safety precautions. The activity of the quartz surface can be easily degraded if moisture or aerosol is transported from the gas–liquid separator (GLS). Aerosol can be particularly problematic, as the presence ...

They are formed physiologically as part of normal metabolism but, when they accumulate at high levels in tissues, they can become dangerous for the organism [2], due to the ability to crosslink proteins and disrupt their structure and thus functions [1]. An exogenous source of AGEs is ...
