| a geographic information assessment of birth weight and crop production patterns around mother's residence. | a landscape approach using remote sensing (rs) and geographic information system (gis) technologies was developed to identify the proximity of maternal residence to agricultural areas, and the association between crop production patterns around mothers residences and low birth weight was evaluated. satellite data obtained for weld county, colorado, in 1991 and 1993 were digitally processed to generate crop location maps for this study. gis procedures were then used to determine crop types within ... | 2000 | 10662530 |
| revegetation of high zinc and lead tailings with municipal biosolids and lime: greenhouse study. | acidic (ph 4.1) and high cd, pb, and zn mine tailings (mean +/- sd: 17 +/- 0.4, 3800 +/- 100, and 3500 +/- 100 mg kg(-1), respectively) from an alluvial tailings deposit in leadville, colorado were amended with municipal biosolids (bs) (224 mg ha(-1)) and different types of lime (calcium carbonate equivalent of 224 mg ha(-1) caco3) in a greenhouse column study to test the ability of the amendments to neutralize surface and subsoil acidity and restore plant growth. the types of lime included coar ... | 2007 | 17940260 |
