Beginning with this post, these columns will be focused on one issue and will be posted as topics emerge rather than on a strict weekly schedule.

Exposure to chemicals, radiation, dust, heat and other stressors at work are a perennial concern. Recent items highlight some of the dangers in nail salons, e-waste recycling facilities and asbestos-related industries.

NailSalonsAndExposuresThe IAQ Video Network and Cochrane & Associates produced a brief video, Nail Salons & Chemical Exposure Concerns. The video describes how brief exposures to the chemicals found in nail and beauty products from occasional visits to a salon may not be of concern, but for hundreds of thousands of salon workers who are exposed for several hours and many days each week, attention needs to be directed toward reducing exposures. Identifying which chemicals are in products, using less hazardous products, improving ventilation and reducing chemical contact with skin can all reduce risks for workers.

ewasteA serious hazard from electronics recycling facilities is described in an article from Medical Xpress: “The disposal and recycling of electronic devices has increased exposure to lead and other toxicants and created ‘an emerging health concern,’ according to a pediatrician who directs the Environmental Health and Lead Clinic at Cincinnati Children’s Hospital Medical Center.” Lead, often found in electronic devices, is extremely toxic to fetuses and children, with even miniscule exposures able to cause permanent damage to the brain and nervous system. Residues that remain on workers’ skin, clothing, shoes, and other personal items can be brought to their cars and homes, exposing their families to these contaminants. The news article references a case study of two young children whose blood lead levels were critically high from their father’s take-home contamination from his job at an e-scrap recycling facility.

An April article from The Seattle Times describes the verdict in a case of take-home exposures resulting in a woman’s death from mesothelioma, a rare form of cancer usually associated with exposure to asbestos. Although the woman had never worked with asbestos, she had handled and washed her husband’s work clothes—contaminated with asbestos fibers—decades earlier. This is just one recent example of illness from take-home asbestos exposures, which have been known to be hazardous for decades.

In 1995, the CDC’s National Institute for Occupational Safety and Health published a report finding “that take-home exposure is a widespread problem.” Workplace measures found to be effective in preventing take-home exposures included these:

  • reducing exposure in the workplace
  • changing clothes and shoes before going home and leaving soiled clothing at work for laundering
  • storing street clothes in separate areas of the workplace to prevent contamination
  • showering before leaving work
  • prohibiting removal of toxic substances or contaminated items from the workplace
  • preventing family members from visiting the workplace

This post is part of a regular series that summarizes and highlights recent Your Health items and trends. Readers can follow CHE’s Your Health news feed or subscribe via RSS. See all Your Health columns.

While individual actions to safeguard or improve health are important, we cannot individually address broad issues regarding pollutants, food supply, access to health care, poverty, climate change, infectious diseases and other issues that impact the health of individuals and communities. Join CHE to strengthen the science dialogue on environmental factors impacting human health and to facilitate collaborative, prevention-oriented efforts to address environmental health concerns.

Bringing attention to specific resources and findings does not mean CHE endorses or validates them. We highlight the emerging science and its implications for Your Health, knowing that thinking will continue to evolve as new studies are published.

Exercise and Health

Other than diet, exercise is probably the contributor to health that we have the most control over as individuals. Three studies this week provide evidence that exercise affects several aspects of health, sometimes in combination with other factors.

bicyclingAs reported in ScienceDaily, Exercise can improve brain function in older adults. A study was conducted with healthy but underactive or sedentary adults ages 65 and older who showed no signs of cognitive decline. Individuals were randomly assigned to one of four groups: those without any change in their exercise (the control group), and groups that exercised moderately for 75, 150 or 225 minutes per week. All groups who exercised saw some benefit, with greater amounts of exercise related to greater cardiorespiratory fitness and less perceived disability at the end of six months. Those who exercised also saw benefits in cognitive test scores, particularly in improved visual-spatial processing, and an increase in their overall attention levels and ability to focus. In sum, better scores on cognitive tests were related to cardiorespiratory fitness rather than the number of minutes of exercise, so the study concludes that cardiorespiratory fitness may be an appropriate goal for maintaining both physical and cognitive health as we age.

Phthalates

Phthalates are a group of chemicals used to soften and increase the flexibility of plastic and vinyl; some are also used in cosmetics and personal care products. Six phthalates are currently banned from use in many products for children due to evidence of reproductive and neurodevelopmental harm. A Time Magazine article, These plastic chemicals may be just as dangerous as what they replace, reported that as research about one particular phthalate, DEHP, showed it to be a probable human carcinogen and associated with other health effects, manufacturers began to replace it with DINP and DIDP, two other phthalates. Two recent studies have shown a connection between adverse effects from these two replacement chemicals. The first study links high blood pressure in children 6-19 years old and the presence of DINP and DIDP in urine. The second study, from the same researchers, found a link between the replacement phthalates in urine and insulin resistance in adolescents 12-19 years old. Neither study was designed to determine if the phthalates caused the conditions.
