Researchers at the University of Copenhagen have found several hundred different chemical substances in tap water stored in reusable plastic bottles. Several of these substances are potentially harmful to human health. There is a need for better regulation and manufacturing standards for manufacturers, according to the chemists behind the study.
Have you ever experienced the strange taste of water after it has been in a reusable plastic bottle for a while? It appears that there is a solid, yet worrying reason for this.
Two chemists from the University of Copenhagen have studied which chemical substances are released into liquids by popular types of soft plastic reusable bottles. The results were quite a surprise.
“We were taken aback by the large amount of chemical substances we found in water after 24 hours in the bottles. There were hundreds of substances in the water – including substances never before found in plastic, as well as substances that are potentially harmful to health. After a dishwasher cycle, there were several thousand,” says Jan H. Christensen, Professor of Environmental Analytical Chemistry at the University of Copenhagen’s Department of Plant and Environmental Sciences.
Endocrine disruptors and insecticide
Professor Christensen and fellow researcher Selina Tisler detected more than 400 different substances from the bottle plastic and over 3,500 substances derived from dishwasher soap. A large portion of these are unknown substances that the researchers have yet to identify. But even of the identified chemicals, the toxicity of at least 70 % remains unknown.
Photo-initiators are among the toxic substances in the water which worry the researchers. These are known to have potentially harmful effects on health in organisms, such as being endocrine disruptors and carcinogens. Furthermore, the researchers found a variety of plastic softeners, antioxidants and release agents used in the manufacture of the plastic, as well as Diethyltoluamide (DEET), commonly known as the active substance in mosquito spray.
Chicken nuggets, burritos and other popular items consumers buy from fast food outlets in the United States contain chemicals that are linked to a long list of serious health problems, according to a first-of-its-kind study.
Researchers at the George Washington University and their colleagues bought fast foods from popular outlets and found 10 of 11 potentially harmful chemicals in the samples, including phthalates, a group of chemicals that are used to make plastics soft and are known to disrupt the endocrine system. The research team also found other plasticizers, chemicals that are emerging as replacements to phthalates.
“We found phthalates and other plasticizers are widespread in prepared foods available at U.S. fast food chains, a finding that means many consumers are getting a side of potentially unhealthy chemicals along with their meal,” Lariah Edwards, lead author of the study and a postdoctoral scientist at GW, said. “Stronger regulations are needed to help keep these harmful chemicals out of the food supply.”
I am reblogging this because I had no idea about the subject at all. We are organic machines and have certain physical requirements, like exercise, also certain vulnerabilities as evidenced in the post.
The recent trend for “cleaner,” more natural, unprocessed foods for improved health and well-being has also led to a shift towards household and beauty products that are also more natural and without preservatives, and possibly for good reason.
According to recent research, consumers’ extra attention to what they are putting on their bodies and in their homes could be beneficial for health, with a new study finding that one in three Australians report health problems related to fragranced products.
Professor Anne Steinemann from the University of Melbourne School of Engineering led a survey of a random sample of 1,098 people taken from a large, web-based panel held by Survey Sampling International (SSI).
She found that when exposed to fragranced products, 33 per cent of Australians suffer a variety of adverse health effects, including breathing difficulties, headaches, dizziness, rashes, congestion, seizures, nausea, and a range of other physical problems.
Exposure to bisphenol A (BPA) and other endocrine-disrupting chemicals (EDCs) may reduce levels of vitamin D in the bloodstream, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.
The study is the first to find an association between EDC exposure and vitamin D levels in a large group of U.S. adults. EDCs are chemicals or mixtures of chemicals that can cause adverse health effects by interfering with hormones in the body. The Society’s Scientific Statement on EDCs examined more than 1,300 studies that found links between chemical exposure and health problems, including infertility, obesity, diabetes, neurological problems and hormone-related cancers.

England had several early advocates of the curative value of sun and fresh air. Physician John Lettsom (1744-1815) prescribed sea air and sunshine for children who were suffering from tuberculosis (TB). In 1840, surgeon George Bodington noted that those who worked in the open air—farmers, plowmen, shepherds—were generally free of TB, while those who spent much of their time indoors seemed more susceptible to it.
I love this kind of information. Sunshine and fresh air are good for us. Who’da thunk it?
I think we are all hard-wired to know simple, wonderful facts like this, but the information gets lost in the myriad facts of the mental mayhem that makes up modern living. Now we have science backing up our own intuition.
I know I am going to enjoy riding my bike out in the sun even more now.
