Pool Water May Strip Tooth Enamel (Futurity.org)
Taking a dip in the backyard pool may cause permanent damage to teeth if chlorine and pH levels are not properly maintained.
“Improperly maintained pool chlorination in swimming pools can cause rapid and excessive erosion of dental enamel,” says Leila Jahangiri, a clinical associate professor prosthodontics of New York University (NYU).
“It is a difficult balance to maintain home pools properly,” Jahangiri contends. “Proper pool chlorine and pH levels need to be monitored and maintained on a weekly basis”…More…
The expert panel that evaluates cancer risks today said that cell phones might possibly cause brain cancer.
The announcement comes from the International Agency for Research on Cancer (IARC). Like the World Health Organization, the American Cancer Society relies on IARC for evaluation of cancer risks.
“After reviewing all the evidence available, the IARC working group classified radiofrequency electromagnetic fields as possibly carcinogenic to humans,” panel chairman Jonathan Samet, MD, chair of preventive medicine at the USC Keck School of Medicine, said at a news teleconference. “We reached this conclusion based on a review of human evidence showing increased risk of glioma, a malignant type of brain cancer, in association with wireless phone use”…More…
In addition to its damaging effect on the environment and its illegal smuggling into developing countries, researchers have now linked e-waste to adverse effects on human health, such as inflammation and oxidative stress – precursors to cardiovascular disease, DNA damage and possibly cancer.
In a study published on May 31, in IOP Publishing’s journal Environmental Research Letters, researchers took air samples from one of the largest e-waste dismantling areas in China and examined their effects on human lung epithelial cells.
E-waste, or electronic waste, describes end-of-life electrical goods such as computers, televisions, printers, and mobile phones. Each year between 20-50 million tons of e-waste is generated worldwide, 100,000 tons of which is exported from UK shores, according to a recent BBC Panorama programme. A large proportion of worldwide e-waste is exported to China.
Due to the crude recycling process, many pollutants, such as persistent organic pollutants and heavy metals, are released from e-waste, which can easily accumulate in the human body through the inhalation of contaminated air…More…
Traces of mercury and PCBs are widespread in sport fish in California’s urban coastal waters, a survey released last week by the state water board found.
But 19% of the urban coastline sampled by researchers harbored fish with mercury in such high concentrations that they shouldn’t be eaten by young women and children. Fourteen percent of locations had similarly elevated levels of PCBs.
The findings, part of a two-year inquiry that is the largest statewide survey of contaminants in sport fish along the California coast, examined more than 2,000 fish from three dozen species gathered in 2009 from waters near Los Angeles, San Francisco and San Diego…More…
Tests Reveal Mislabeling of Fish (NY Times)
Scientists aiming their gene sequencers at commercial seafood are discovering rampant labeling fraud in supermarket coolers and restaurant tables: cheap fish is often substituted for expensive fillets, and overfished species are passed off as fish whose numbers are plentiful.
Yellowtail stands in for mahi-mahi. Nile perch is labeled as shark, and tilapia may be the Meryl Streep of seafood, capable of playing almost any role.
Recent studies by researchers in North America and Europe harnessing the new techniques have consistently found that 20 to 25 percent of the seafood products they check are fraudulently identified, fish geneticists say…More…
Attending frequently with medically unexplained symptoms is distressing for both patient and doctor and effective treatment or management options are limited: one in five patients have symptoms that remain unexplained by conventional medicine. Studies have shown that the cost to the NHS of managing the treatment of a patient with medically unexplained symptoms can be twice that of a patient with a diagnosis.
A research team from the Institute of Health Services Research, Peninsula Medical School, University of Exeter, has carried out a randomised control trial and a linked interview study regarding 80 such patients from GP practices across London, to investigate their experiences of having five-element acupuncture added to their usual care. This is the first trial of traditional acupuncture for people with unexplained symptoms.
The results of the research are published in the British Journal of General Practice. They reveal that acupuncture had a significant and sustained benefit for these patients and consequently acupuncture could be safely added to the therapies used by practitioners when treating frequently attending patients with medically unexplained symptoms…More…
Cultured Men Are Happier & Healthier (MedicalXpress)
Men who visit art galleries, museums, and the theatre regularly tend to enjoy better health and are more satisfied with life, reveals a study published online in the Journal of Epidemiology and Community Health.
The study found that both men and women who play musical instruments, paint or visit the theatre or museums felt in better health, enjoyed life more, and were less likely to be anxious or depressed then people who do not participate in cultural activities.
However, the effect was most pronounced in men who were interested in watching and looking at culture rather than doing creative or active cultural activities themselves…More…
