Statistical analysis of urinary delta-aminolevulinic acid (ALAU) excretion in the white-footed mouse associated with lead smelting.
ALAU in white-footed mice trapped in the vicinity of a lead smelter has been measured to study the biological effect of lead smelting operations and the rate at which the ALAU level diminishes after removing animals from contaminated environments. The statistical method which has been developed for this purpose shows that the ALAU levels are initially higher among animals near the smelter and diminish to a common level after 5-6 weeks. The statistical method is generally applicable to a variety of physiological functions which exhibit a decay curve with respect to time.
