Proposed lead-in-air standardputs heat on industrial sources

An official panel has proposed an air quality standard for lead considerably tougher than the Government's existing objective.1 Falling traffic emissions mean that the standard is already met in most urban areas - but industrial sources such as smelters and foundries may cause significant localised breaches.
