Abstract

A personal dust sampler, (3 cm<2>), hangs from a ribbon (10) attached to the user's clothing and requires no pump or power source. Dust in the air is captured by a charged PVC sheet (2) exposed at (2a) but framed by a metal foil (25) and surmounted by a metal conductor plate (6) parallel to (2). The plate (6) is supported by conductive gridwork (3) removeably attached via a flange (30) to a metal base (21). The dust captured is determined by weighing or by measuring the charge loss of the PVC sheet (2). <IMAGE>
