Embryotoxic effects of polybrominated biphenyls (PBB) in rats.

abstract：BACKGROUND:Research often suffers from overspecialization, a practice nurtured in academia and reinforced by funders. Indeed, investigators in household air pollution (HAP) and water, sanitation and hygiene (WaSH), working in poor parts of the world, rarely interact despite having similar training and using similar met...
