Tattoo nanoparticles travel inside the body

Scientists have long known that organic tattoo pigments travel to the lymph nodes because visual evidence shows the lymph nodes taking on the color of the tattoo.

Most tattoo inks contain organic pigments.  However, a chemical analysis had not been done until now.  The additions of preservatives and contaminants in ink revealed the presence of  nickel, chromium, manganese or cobalt.

In a first of it’s kind study,  “Scientists have discovered that micro and nanoparticles from tattoos can travel inside the body and reach the lymph nodes” according to a UPI report.

The study reports that they “were able to prove the presence of several toxic elements, such as Cr and Ni, derived from tattooing”.  However, the report  could not determine if other contamination sources may have contributed to the presence of toxic elements.

 

Sperm count dropping in western world

As published in Scientific American:  LONDON (Reuters) – Sperm counts in men from America, Europe, Australia and New Zealand have dropped by more than 50 percent in less than 40 years, researchers said on Tuesday.

They also said the rate of decline is not slowing. Both findings — in a meta-analysis bringing together various studies — pointed to a potential decline in male health and fertility.

“This study is an urgent wake-up call for researchers and health authorities around the world to investigate the causes of the sharp ongoing drop in sperm count,” said Hagai Levine, who co-led the work at the Hebrew University-Hadassah Braun School of Public Health and Community Medicine in Jerusalem.

The analysis did not explore reasons for the decline, but researchers said falling sperm counts have previously been linked to various factors such as exposure to certain chemicals and pesticides, smoking, stress and obesity.

Microscopic plastic particles contaminate drinking water

Drinking tap water around the world is likely to contain tiny plastic particles according to research conducted at the University of Minnesota School of Public Health and the State University of New York. The research was sponsored by nonprofit Orb Media.

Of 33 tap water samples from across the United States, 94 percent tested positive for the presence of plastic fibers. 1

India came in second with 82 percent of samples tested positive followed by Uganda 82 percent, Indonesia 76 percent and Europe at 72 percent.

No country was without a plastic-positive sample. 2
