چکیده
This clinical epidemiological study will determine if farm workers chronically exposed to organophosphate pesticides (OP) in field work have quantifiable nervous system abnormalities after an exposure season and whether these changes are persistent after a several month period of non-exposure. This cross-sectional study with a follow-up component will compare 50 female orchard farmworkers with chronic low-level OP exposure to controls. Exposure estimates will be based on orchard spray logs, work questionnaires, and biological monitoring (cholinesterase testing). A neurological battery will be used at the end of an exposure season and 5-6 months after no exposure. Several biological markers will be evaluated: cholinesterase, paraoxonase, chlorpyrifos oxonase levels, and muscarinic receptor density in lymphocytes.

Long-term noise exposures: A brief review
Occupational regulations are developed to conserve the hearing of a worker noise-exposed for 8 h per day. Workers often work longer shifts. In order to account for longer exposures, regulators have adopted variations of the equal energy hypothesis in which the ear is modeled as an integrator of acoustic energy over time. Thus time and energy can be traded to produce equal hearing loss. This res...

متن کاملAn evaluation of the NIOSH Lifting Equation: a psychophysical and biomechanical investigation.
Using the results of psychophysical and biomechanical experiments, NIOSH (National Institute for Occupational Safety and Health) Recommended Weight Limit (RWL), the Lifting Index (LI), the form of the asymmetry multiplier, and the criterion for compression force were investigated. Analysis of the results indicated a significant difference between the NIOSH RWL and the reported Maximum Acceptabl...
