Lead concentration as high as 1,60,000 parts per million (ppm) was detected in a sample of 250 cans of oil-based (enamel) house paints, a study has found.
Lead, which is added to paints in order to increase its their durability, speed up their drying and maintain their appearance, is known to be a health hazard, especially for small children. The acceptable international standard is 90 ppm, based on the dry weight of the digested sample.
