Dear EarthTalk: Are there any environmental or human health risks to using
nail polish?
                                                                       -- Deborah Lynn, Milford, CT

Conventional nail polishes dispensed at most drugstores and nail salons contain a
veritable witch’s brew of chemicals, including toluene, which has been linked to a
wide range of health issues from simple headaches and eye, ear, nose and throat
irritation to nervous system disorders and damage to the liver and kidneys.

Another common yet toxic ingredient in conventional nail polish is a chemical
plasticizer known as dibutyl phthalate (DBP). According to the Environmental
Working Group (EWG), a non-profit research and advocacy organization that
campaigns to educate consumers about the health risks of cosmetics, studies
have linked DBP to underdeveloped genitals and other reproductive system
problems in newborn boys.

As such, DBP is banned from cosmetics in the European Union but the Food and
Drug Administration (FDA) in the United States has taken no such action, even
though a recent study by the U.S. Centers for Disease Control and Prevention
found DBP and other toxic phthalates in the bloodstreams of every person they
tested. Further, five percent of women tested who were of childbearing age (ages
20-40) had up to 45 times more of the chemicals in their bodies than researchers
had expected to find.

EWG attributes the prevalence of DBP in young women to widespread use of nail
polish. “Women of childbearing age should avoid all exposure to DBP when they’
re considering becoming pregnant, when they’re pregnant, or when they’re
nursing,” says Jane Houlihan, EWG’s Vice President for Research.

Luckily, safer nail polishes do exist and are readily available at natural health and
beauty supply stores as well as from online outlets such as Natural Solutions and
Infinite Health Resources. These products, from such makers as Honeybee
Gardens, PeaceKeeper, Jerrie, Visage Naturel and Sante, rely on naturally
occurring minerals and plant extracts to beautify nails without the need for toxic
ingredients.

Major nail polish manufacturers are also now getting in on the act. According to
the Campaign for Safe Cosmetics, a coalition of organizations that includes EWG
and the Breast Cancer Fund, Avon, Estee Lauder, Revlon and L’Oreal confirmed
last year that they would begin removing DBP from products. And leading
drugstore brand Sally Hansen has said it is reformulating all of its products to
remove DBP and toluene as well as formaldehyde, which is also known to cause
cancer and reproductive problems.

Exposure to toxic chemicals is not the only health concern associated with nail
salons, where nail fungus and bacteria can lurk on the underside of any emery
board. Women’s health advocate Tracee Cornforth suggests checking out a salon
for cleanliness before signing up for services. She also says to make sure
attendants disinfect all tools and equipment between customers, and even
recommends bringing in one’s own manicure or pedicure kit so as to minimize the
transmission of any unsightly or painful maladies.

EARTH TALK
From the Editors of E/The Environmental Magazine

Dear EarthTalk: I read a disturbing report recently that the long-banned
pesticide, DDT, was being used in Mozambique to combat malaria. Malaria
is a killer, but isn't a return to DDT even scarier?   
                                                                -- Graeme Campbell, South Africa

Much of the developed world banned the use of DDT (dichloro-diphenyl-
trichloroethane) within about 10 years of the 1962 publication of Rachel Carson’s
book, “Silent Spring.” Carson’s book, which is credited by many as having spurred
the creation of the modern environmental movement, documented the ecosystem
damage caused by DDT crop spraying throughout the United States and linked
the pesticide’s use to the disappearance of songbirds and raptors.

Health officials at the time also linked DDT exposure to nerve damage in humans,
and blamed DDT for causing cancer in people who had applied it recklessly.
Today, because of widespread indiscriminate use up through the 1960s, most
people have traces of DDT in their bodies. DDT has since become increasingly
associated with childhood developmental problems, according to the organization,
Beyond Pesticides (BP).

Today, two dozen countries--including Mozambique and nine other African
nations--permit the use of small amounts of DDT for controlling specific insect-
borne diseases, including malaria. Malaria kills one million people, including
800,000 African children, every year. Dr. Arata Kochi, leader of the World Health
Organization’s (WHO’s) global malaria program, strongly advocates using DDT to
fight malaria, claiming that it poses little or no health risk when sprayed in small
amounts on the inner walls of people’s homes.

“Indoor residual spraying is useful to quickly reduce the number of infections
caused by malaria-carrying mosquitoes…and presents no health risk when used
properly,” agrees Anarfi Asamoa-Baah, WHO’s assistant director-general for
HIV/AIDS, tuberculosis and malaria.  Asamoa-Baah insists that DDT’s public
health benefits far outweigh its risks.

Jay Feldman, executive director of Beyond Pesticides, disagrees and advocates
for techniques that do not rely on pesticides like DDT. “The international
community has a social responsibility to reject the use of this chemical and to
practice sound and safe pest management practices,” he says. Feldman cites a
recent study showing South African women living in DDT-treated dwellings to have
77 times the internationally accepted limit of the chemical in their breast milk.
Researchers postulate that large amounts of DDT may have contaminated
drinking water, exposing entire villages. “This highlights why no society can be
unconcerned with DDT’s impact” on health and the worldwide ecosystem,
Feldman says.

Feldman is calling for alternative strategies for disease control, including
addressing the conditions of poverty that lead to mosquito breeding. We should
“no longer treat poverty and development with poisonous band-aids, but join
together to address the root causes of insect-borne disease, because the
chemical-dependent alternatives are ultimately deadly for everyone,” says
Feldman.
