Microenvironmental analysis of residential exposure to chromium-laden wastes in and around New Jersey homes.

The purpose of this study was to identify the significant microenvironments that can lead to chromium exposure in Hudson County, New Jersey residential settings near or on soil contaminated with chromium waste. Measurements were made in indoor air, outdoor air, and house dust. Surface dust was found to be the best index of potential Cr exposure. The values of Cr in Hudson County household dust ranged from 3.25-320 ng/cm2 in wipe samples and 1.0-12 ng/cm2 in vacuum samples. Elevated Cr in household dust was found to be related to residential locations near large chromium waste sites, household cleaning habits, and house renovation activities. Outdoor Cr air levels were similar to those obtained in other urban areas at these seasons of the year, approximately 5-7 ng/m3. Comparisons with measurements of the Cr levels in urine found that the elevated Cr in dust was associated with elevated excretion of Cr. Site-specific Cr differences in household dust suggest different sources and routes of exposure. Within the total group of homes in the present study, Cr in household dust was the major influence on household exposure.

ALS and pet exposure.

To examine animal exposure in ALS patients, a case-control study was undertaken on 40 ALS patients and 40 closely matched controls. Exposure to pets of any kind and to small dogs in the period from birth until 10 years before onset of ALS symptoms was significantly increased. Affected men showed a trend toward increased exposure to neurologically ill pets, but there was no significant difference when male and female cases were grouped. No differences between ALS cases and controls were observed in exposure to any other single animal species. There may be a link between ALS and exposure to house pets.
