摘要:

The study examines the relationship between urban air pollution, as indexed by total suspended particulate concentrations, in Lake and Porter Counties in Indiana, and the Calumet region of South Chicago, Illinois. This area exhibits a pollution gradient conducive to a study of this type; high pollution levels in a heavily industrialized urban region, and low to moderate pollution levels in an adjoining rural region.

摘要:

Samples of the American (eastern) oyster,Crassostrea virginica, were collected from 11 locations along the South Carolina coast. There were wide variations in iron concentrations, although these were not obviously related to geographical location. Copper concentrations were apparently indicative of the environment, especially in the Wando River, an estuary near Charleston, South Carolina. Oysters from the upper Wando contained 3–20 times as much copper as oysters from other sites.

摘要:

The volatile components (ppm of total solids) emitted by corn silk were found to be l‐butanol (1), 1‐pentanol (7), 1‐hexanol (1), (E)‐4‐hexen‐1‐ol (4), 3‐methyl‐1‐butanol (1), acetaldehyde (5), hexanal (4), 2‐furancarboxaldehyde (furfural) (2), and phenylacetaldehyde (12). Phenylacetaldehyde was found to attract the corn earworm, European corn borer, soybean looper, tarnished plant bug,Cisseps fulvicollis, and forage looper. Combining phenylacetaldehyde with butanol or acetaldehyde increased attractiveness to some species; other combinations reduced attractiveness.

摘要:

Water taken some two days after a mass mortality of white amur in an Orange County, Florida, holding pond was extracted with chloroform. The concentrated extracts were analyzed by high pressure liquid chromatrography (HPLC) and were found to contain rotenone, a known fish toxicant, upon comparison with an authentic sample. The water contained, by estimation, 1.8 ppm rotenone. Additional studies were made of the degradation of rotenone and associated materials of commercial samples in lake water in contact with sediment. The carrier materials degrade rapidly, i.e., within two days, though rotenone should persist for purposes of HPLC analysis for two days under ambient environmental conditions. The origin of rotenone in this water is unknown.
