Key words: accuracy of atomic absorption analytical techniques: accuracy of isotope dilution analytical techniques; errors in lead analyses; lead; lead contamination evaluation and control; lead in animals and plants; pollution, lead; sampling techniques; trace analysis of lead; waters, lead in. Most present analytical practices for lead cannot reliably determine lead concentrations at the 1 ng/g level because of a universal lack of familiarity with lead contamination during sample collecting,...
