Touching thermal-paper receipts could extend
BPA retention in the body
When people handle
receipts printed on
thermal paper
containing the
endocrine disruptor
bisphenol A (BPA), the
toxic chemical could
linger in the body for a
week or more. Jonathan
W. Martin of Stockholm University and Jiaying Liu of the
University of Alberta asked six male volunteers to handle
paper containing isotopically labeled BPA for five minutes.
The volunteers then put on nitrile gloves, wore them for two
hours, removed them, and washed their hands with soap.
Afterward, the researchers measured the labeled BPA and
its metabolites in the volunteers’ urine regularly for two
days and then once again a week later. The study only
traced the isotopically labeled (deuterated) BPA and its
metabolites, so any additional BPA exposure from other
sources was not monitored.

O texto discorre sobre uma pesquisa cujo objetivo foi
A
determinar como o manuseio de papel térmico pode
contaminar uma pessoa com bisfenol A, considerando
que a concentração foi monitorada utilizando-se um
BPA em que átomos de 1H foram substituídos por 2H.
B
analisar de que forma o uso de luvas nitrílicas lavadas
com sabão e contendo BPA deuterado pode
contaminar receitas impressas em papel térmico que
contém um disruptor endócrino.
C
monitorar, durante uma semana ou mais, a cinética de
eliminação de um disruptor endócrino, bisfenol A
(BPA), do corpo humano que foi contaminado pelo uso
de luvas nitrílicas.
D
verificar como um papel térmico deteriorado por
átomos de 2H poderia contaminar as mãos de uma
pessoa, mesmo que ela estivesse usando luvas
nitrílicas durante duas horas e depois as removesse.
