Risk of BPA |
Bisphenol
A (BPA) is a commonly used chemical in the manufacture
of a variety of common products, including baby bottles,
as well as the linings of food and drink cans. Long-term
low dose exposure is thought to have negative health
effects because BPA interacts with hormonal systems
in babies aged between three and six months compared
with adults.
The study simulated the plasma concentrations of BPA
in young children under typical BPA exposure scenarios
by using a mathematical model. Virtual adult humans
were scaled to children based on the physiological differences
between them.
The researchers suggest that current threshold limits
are just sufficient for infants with normal or high
tolerance of BPA, but may not be sufficient to protect
babies with low tolerance rates.

| Indoor
Pollution Causes Asthma |
Children
spend nearly 80 percent of their time indoors, be
it home or school. If indoor air is polluted, it can
cause various diseases to children, including Asthma.
A study by researchers at the Johns Hopkins University,
supported by National Institute of Environmental Health
Sciences and various other environmental and health
institutes, found an association between increasing
levels of indoor particulate matter pollution and
the severity of asthma symptoms among children.
Meredith C. McCormack, lead author of study, adds,
"We found that substantial increases in asthma
symptoms were associated both with higher indoor concentrations
of fine particles and with higher indoor concentrations
of coarse particles."
