The current definition, however, expressively prohibits the use of any lead additive in the production of unleaded gasoline. The regulations provide limitations on pollutant concentrations in waste water discharges from point source categories and represent the degree of reduction in pollutant concentration that is attainable through demonstrated technologies for new and existing sources, standards of performance for new sources, and pretreatment standards for new and existing sources. The effluent limitation establish the maximum discharge of pollutants allowed for a 1 day and for a monthly average. A solid waste containing lead or lead compounds may be defined as a hazardous waste if it exhibits the characteristic of toxicity. Contamination in Human Food and Animal Feed Lead also appears on the FDA's list of poisonous and deleterious substances which was established to control levels of contamination in human food and animal feed.
