Study Reveals Rich And Poor People Have Different Chemicals In Them

chemicalsRich people’s bodies are filled with mercury, poor people’s with lead and plastics, Gizmodo reports:

New research from the University of Exeter looks at the association of 18 different chemicals in the body and socioeconomic status. Long story short, everybody’s bodies are full of poison. Rich people poison just comes from fancier sources.

People from higher socioeconomic status showed higher levels of mercury, arsenic and benzophenone-3. Researchers think that the first two come from higher consumption of shellfish and seafood, whereas the benzophenone-3 likely comes from sunscreen.

The chemical profiles of people from lower socioeconomic status are completely different. Their bodies are full of lead, cadmium and different types of plastics. These chemicals could come from cigarette smoke but likely come from poor diet. The research is bolstered by an earlier study from Boston University that found higher levels of Bisphenol-A in poor people’s bodies, perhaps from consuming more canned food than the rich.

Was Lead Pollution The Main Cause Of High Crime And Violence In 1970s, ’80s, and ’90s America?

It wasn’t crack cocaine, poverty, or the breakdown of the nuclear family that caused the spike in violent criminality. Most likely, it was automobile fumes. Mother Jones has a bombshell story:

In city after city, violent crime peaked in the early ’90s and then began a steady and spectacular decline. By 2010, violent crime rates in New York City had plunged 75 percent from their peak in the early ’90s. Washington, DC['s] violent crime rate has dropped 58 percent since its peak. Dallas’ has fallen 70 percent. Newark: 74 percent. Los Angeles: 78 percent.

Lead emissions from tailpipes rose steadily from the early ’40s through the early ’70s, nearly quadrupling over that period. Then, as unleaded gasoline began to replace leaded gasoline, emissions plummeted. Intriguingly, violent crime rates followed the same pattern. The only thing different was the time period: the two curves looked eerily identical, but were offset by about 20 years.

Lead Poisoning Lurks in Spices

By Alice Park for Time:

Most parents have already cleared their children’s toy boxes of playthings containing lead-laden plastics or paint. But according to a new study published on Monday in Pediatrics, the toxic heavy metal may continue to lurk in other, less expected sources in the home — like in the kitchen pantry.

After several reports of lead poisoning in Indian children in the Boston area were linked to consumption of Indian spices, researchers at Children’s Hospital Boston and the Harvard School of Public Health decided to measure the amount of lead in the seasonings as well as in ceremonial powders commonly used to mark newborn Indian infants for religious and cultural purposes.

The team visited 15 Indian specialty stores in the Boston area and purchased 71 cultural powders and 86 spices and food products. About 25% of the food items, including spices such as cardamom, fenugreek and chili powder, contained more than 1 microgram of lead per gram of product.
