To the Editor: In their Research Letter about
exposure to toxic fumes from the Union Carbide pesticide plant in Bhopal,
India, Mr Ranjan and colleagues1 found selective
growth retardation in boys, but not in girls, who were either directly exposed
or born to exposed parents. The assignment of exposure appears to be have
been performed on an ecological rather than an individual basis, thus leading
to the probability that some individuals (depending on their location on the
night of the incident) might not necessarily have been exposed.
