Lead levels
Sir, —The harmful effects of environmental lead have been investigated and tabulated in overwhelming detail but, as usual, without total agreement. Lead levels in food in New Zealand give some scientists “cause for concern”; the Health Department has reduced lead in: solder from 98 per cent to 2 per cent in soft drink and baby food cans. Two thousand children in Christchurch could have blood l£ad levels that are “hazardous”; the Health Department has banned paint containing lead, except for “certain uses”. If the World Health Organisation’s acceptable blood lead level figures wjsre
imposed in industry, a union official said recently, every lead process in-the, world ■would have to' be closed. The Health Department believes that there is “minimal risk from lead in air at the levels measured at present” and, although this assertion is,highly contentious, lead in petrol will nor be reduced, for economic reasons, until alternatives are' available in approximately five years.' — Yours, etc., JANET R. HOLM. April 6, 1980.
