There is growing evidence that biodiversity and environmental and human health can be affected by mixtures of toxic chemicals in the environment and in food for human consumption. Today more than 350,000 chemicals are manufactured on an industrial scale, reaching the environment and food chains. As a result, currently regulated and monitored environmental contaminants represent only a fraction of the total chemical exposure of organisms. Routine testing targets known molecules that may represent only a small proportion of the total contaminant load, while many molecules not known to date may also cause potential physiological damage, yet are not considered in these targeted routine tests. Marine mammals being long-lived species, located at the top of marine food webs and with a high capacity to accumulate high concentrations of contaminants are therefore a good biological model for this type of study, and we have therefore also set up a non-targeted screening strategy (NTS) with several research laboratories (Cariou et al. 2020).
