Environmental justice has become a major focus of research within the
environmental social sciences. Early studies mostly examined the unequ
al distribution of natural resource hazards in an advanced capitalist
political-economy. More recent studies have quantitatively gauged the
relationship between sociodemographic factors and exposure to toxic ch
emical pollution. In this article, I use presentations at the recent m
eetings of the American Sociological Association (Toronto, August 1997
) to suggest where the third generation of research into environmental
justice may be heading. The literature is at a crossroads. We know en
ough to argue that there is a problem, but we cannot clearly articulat
e relationships, causation, or policy demands. New research techniques
and social theories may begin to allow us to accomplish these more am
bitious tasks.
