Perchlorate levels in samples of sodium nitrate fertilizer derived from Chilean caliche.
TLDR
Paleogeochemical deposits in northern Chile are a rich source of naturally occurring sodium nitrate (Chile saltpeter), but information on natural attenuation, plant uptake, use/application, and dilution is too limited to evaluate the significance of these findings, and further research is needed.

Volatile organic pollutants in new and established buildings in Melbourne, Australia.

  • 1 March 2002
TLDR
It is shown that persistent low levels of volatile organic pollutants in established dwellings can occur due to long-term emissions from building materials, and emissions were limited by material diffusion processes. Expand
Perchlorate uptake by salt cedar (Tamarix ramosissima) in the Las Vegas wash riparian ecosystem.
TLDR
It is suggested that salt cedar might play a role in the ecological distribution of perchlorate as an environmental contaminant, which has the potential to affect the potable water source of tens of millions of people as well as irrigation water used on a variety of crops, including much of the lettuce produced in the USA.

  • Indoor air
  • 1 December 1999
TLDR
Processes involved in pollutant emissions from a dry-process photocopier have been investigated in a controlled room dynamic environmental chamber and small emissions of nitrogen dioxide, ozone and formaldehyde were observed but were difficult to interpret. Expand
Chamber assessment of formaldehyde and VOC emissions from wood-based panels.

  • Environmental Science, Medicine
  • Indoor air
  • 1 September 1999
TLDR
Volatile organic emissions from particleboard, medium density fibreboard (MDF) and office furniture have been measured in dynamic environmental chambers, both small and room-sized, and the compounds emitted differed from those reported in other countries. Expand
Characterization of the fiber diameter distributions of synthetic mineral fiber products and their dusts.
  • S. K. Brown
  • Materials Science, Medicine
  • American Industrial Hygiene Association journal
  • 1992
TLDR
Airborne fibers emitted during work operations with products had diameter distributions similar to those of ground fibers, indicating that similar breakdown of finer fibers into shorter lengths occurs for dusts emitted during such operations. Expand
Asbestos exposure during renovation and demolition of asbestos-cement clad buildings.
  • S. K. Brown
  • Materials Science, Medicine
  • American Industrial Hygiene Association journal
  • 1 May 1987
TLDR
Limited results suggest that concentrations may be reduced substantially by avoiding abrasion of surfaces, and Precautions such as respiratory protection and clothing decontamination are considered to be essential for the demolition of roofing containing amosite or crocidolite by the procedures investigated. Expand
Health symptoms and occupational exposure to flea control products among California pet handlers.
TLDR
A statewide telephone survey of health symptoms associated with occupational exposure to flea control products among California pet handlers was conducted in 1987 and eye and skin symptoms and unusual tiredness were elevated among workers who applied flea Control products to animals or facilities. Expand
Protecting agricultural applicators from over-exposure to cholinesterase-inhibiting pesticides: perspectives from the California programme.
California's requirement for medical supervision of applicators regularly handling Toxicity Category I and II organophosphate and carbamate cholinesterase-inhibiting pesticides is examined from aExpand
Cholinesterase activity depression among California agricultural pesticide applicators.
TLDR
Pesticides most frequently associated with cholinesterase depressions exceeding California threshold values included mevinphos (Phosdrin), oxydemeton methyl (Metasystox-R), methomyl (Lannate), and acephate (Orthene); these pesticides included organophosphates in toxicity categories I and II and one carbamate in toxicity category I.
