Levels of microplastics in human brains may be rapidly rising, study suggests

"The exponential rise in microplastic pollution over the past 50 years may be reflected in increasing contamination in human brains, according to a new study."

"The human body is widely contaminated by microplastics. They have also been found in blood, semen, breast milk, placentas and bone marrow. The impact on human health is largely unknown, but they have been linked to strokes and heart attacks".

The Best, Longlasting Hip Replacement Implants: Which manufacturers market these desirable joint replacements and which models are preferred? #hip #replacement #prosthesis #revision #ceramic #zirconium #polyethylene

Howard G. Smith MD, AM on Instagram: "The Best Hip Replacement Implants Nothing is forever, and we know that hip replacement implants do wear out. A new study from the UK’s University of Bristol concludes that the hip prostheses least likely to require replacement within 15 years are those with delta ceramic or oxidised zirconium heads and highly crosslinked polyethylene liners or cups. The researchers reviewed the records of more than 1,026,000 records in the British National Joint Registry. Which manufacturers market these desirable joint replacements and which models are preferred? Stryker’s Accolade II and Trident. Zimmer Biomet’s M/L Taper and Persona. Johnson & Johnson’s DePuy Synthes R3 Acetabular and Corrail Hip Systems. Smith & Nephew R3 Acetabular System.

Can Plastic Waste Be Transformed Into Food for Humans?

Using bacteria to take a bite out of plastic pollution is not new. But can the same microbes be used as a food source?

In recent years, Russia has seen an increase in the production of ethylene polymers in primary forms. Polyethylene production in Russia increased from 26.6% to 33.02% of the total plastic production from 2018 to 2023. In 2023, 3,536 thousand tons of ethylene polymers in primary forms were produced in Russia, which is +1.5% more than the production volume of the previous year.

The largest producers of polyethylene in Russia

Traditionally, polyethylene is a plastic and is included in the category of ethylene polymers, from which, in particular, large diameter tubes and pipeline parts, cable products, packaging bags, shampoo bottles, etc. are made.
