While no studies relating to lead and the environment are currently being undertaken on a formal basis, a range of measures is being pursued to prevent, control and monitor environmental pollution arising from lead emissions. These include; national air quality standards for lead, enforceable through the Air Pollution Act, controls on the lead content of petrol which can be marketed and the provision of incentives to encourage increased use of unleaded petrol, the application of strict quality standards to all water supplies intended for human consumption, including standards applying to lead content, controls of industrial and other emissions and discharges by means of licensing and other provisions under the Air Pollution and Water Pollution Acts, the strengthening of controls provided for in the Environmental Protection Agency Act, 1992 and the prohibition on the use of lead in jointing techniques for pipes under the Building Regulations, 1991.
In addition to the foregoing measures, controls in relation to other sources are provided for by other Ministers; for example I understand that the Minister for Health has made regulations which lay down limits for lead in foods and beverages, and that regulations have been made by the Minister for Industry and Commerce relating to the safety of toys.
