Correlates of residential wiring code used in studies of health effects of residential electromagnetic fields

Article Abstract:

The home wiring code is the most widely used metric for studying health effects, if any, of electromagnetic fields (EMFs). Other home characteristics were collected from information on file in the tax assessor's office; estimated traffic density was recorded from state data; personal characteristics of mothers of reproductive age were obtained by interview. Women in homes coded for very high current configuration were more likely to be in jobs involving manual labor. Their homes were older and assessed at lower values and located where traffic densities were higher. In future EMF research, confounding of wiring code associations must be considered carefully.

Air pollution as an underappreciated cause of asthma symptoms

Article Abstract:

Extensive research has documented that ozone can make asthma symptoms worse. Ozone is a component of air pollution, so children with asthma should try not to exercise or engage in strenuous activities on days when air pollution is most severe. Governments can also act on children's behalf, since air pollution is one of the few environmental triggers that can be regulated.

Association of low-level ozone and fine particles with respiratory symptoms in children with asthma

Article Abstract:

Ozone may make asthma symptoms worse in some children, according to a study of 271 children. The children were more likely to wheeze, experience chest tightness and shortness of breath, and use their medications on days when ozone levels were highest. Small particulate matter was not associated with an increase in symptoms.
