Contaminated By Wealth

Christopher Mims flags a UK study revealing that the rich absorb different toxins than the poor:

People who can afford sushi and other sources of aquatic lean protein appear to be paying the price with a buildup of heavy metals in their bodies, found Jessica Tyrrell and colleagues from the University of Exeter. Using data from the US National Health and Nutrition Examination Survey, Tyrrell et al. found that compared to poorer people, the rich had higher levels of mercury, arsenic, caesium and thallium, all of which tend to accumulate in fish and shellfish.

The rich also had higher levels of benzophenone-3, aka oxybenzone, the active ingredient in most sunscreens, which is under investigation by the EU and, argue some experts, may actually encourage skin cancer.

Ben Richmond notes the toxins more common at the bottom of the social ladder:

Those of lower socioeconomic status had higher levels of lead, cadmium and three types of phthalates—compounds commonly found in plastics.  The reasons for these disparate chemical levels point to disparate lifestyles and environments. [Also], lead and cadmium come into those of lower socioeconomic status via cigarette smoking and their jobs.
