A Grass-roots Revolution In Pollution Control

People living near oil refineries or industrial plants are "turning to an unlikely solution: a five-gallon bucket equipped with a sturdy plastic bag and a hand-held vacuum pump. The items are the basis of a simple air-sampling device that is, increasingly, empowering communities from Norco, La., to Cuddalore, India... Residents take air samples with a bucket provided by an international environmental group called the Bucket Brigade, then have it analyzed at a lab. Results arrive a few weeks later. Armed with hard data, community activists can more easily educate the public and lobby industries and governments to make improvements."
