| Abstract/Contents: | States that "lead poisoning of animals is a universal toxicological problem. Feed contaminated with lead of atmospheric source near a battery smelter in Minnesota was diagnosed as the cause of death of cattle and horses," and "automobile exhausts are a well-recognized source of lead contamination of plants used for feed." Explains that "while the `normal' lead content of oven-dried foods is 0.1 to 1.0 ppm [parts per million], plants grown in high-lead soils may contain 10 times that amount." Declares that "the sandy-loam soils were from the following sources: (A) the surface 25 mm [millimeters] from a farm adjoining the battery smelter (680 ppm lead); (B) the surface 25 mm from the bank of a well-traveled, 4-lane highway (59 ppm lead); (C) control, from the normal greenhouse supply (12 ppm lead); and (D) a 25-mm layer at a 150-mm depth from the same farm as soil A (95 ppm lead)." Explains that three crops were harvested from each pot: the first after 69 days when the plants reached heading stage, the second after 73 days regrowth without heading, and the third at heading stage after 37 days regrowth, with chelates added after the harvest of the second crop. States that "only the highly-contaminated surface soil obtained from the smelter area (soil A) produced first-crop grass with significantly more lead than the control." Also states that "the addition of chelates to the soils prior to the third-crop growth resulted in a distinct rise in lead concentration in grass growing in the two most-contaminated soils (A and D)." Concludes that "of most practical significance was the fact that even the greatest grass lead concentration (34.5 ppm in third-crop brome, soil A) was far below the level which would be toxic to animals consuming the grass; at least 150 ppm lead in the total ration dry matter were needed to approach levels observed to be toxic to cattle and horses. No consistent differences in height, vigor, or yield appeared between plants growing in the four soils." |
