Ethnicity and hazard information dissemination

Citizens from two communities were questioned regarding the sources from which they have previously obtained information about environmental hazards and their preferences for different communication channels. Three ethnic groups—whites, blacks, and Mexican-Americans—were represented among those questioned. While all three ethnic groups described similar patterns of past information receipt, it was found that Mexican-Americans obtained more information through social network contacts than whites or blacks. Ethnic differentials emerged when citizens were asked about preferred sources for information receipt. While radio was identified as desirable by all three groups, only minority citizens expressed a preference for local television as a dissemination mode and only Mexican-Americans favored neighborhood meetings. Mailed dissemination and newspapers were preferred primarily by whites and blacks. The implications of the results for the conduct of hazard information dissemination are examined.

Characterization of aliphatic hydrocarbons in deep subsurface soils near the outskirts of Beijing, China

Thirty-nine deep subsurface soils( 150—180 cm depth) near the outskirts of Beijing were investagated. The concentrations including n-alkanes from C13 to C36, pristane and phytane were in the range of 0.60 to 170.10μg/g, with a median value of 4.26. Carbon preference index values for n-alkanes ranged from 1.08 to 2.98, with a median value of 1.48. The percentage contribution of “wax” nalkanes was in the range of 6.03%--46.22%. A predominance of odd/even carbon n-alkanes and unresolved complex mixtures with different shapes and ranges were frequently observed. Factor analysis reduced the data set into three principal components and confirming contributions from low ( 19.58% ), medium ( 20.49% ) molecular weight species and long-chain n-alkanes (43.41% ), respectively.Molecular biomarkers such as pristane, phytane, hopanes and steranes were detected. Based on the principal component analysis, the concentration profiles and molecular markers, it was found that the aliphatic hydrocarbons were from both biogenic and anthropogenic sources.
