Occupational settings Battery

The primary routes of entry are ocular and dermal contact, inhalation, and ingestion. Calomel is found in environmental and occupational settings, such as in mercury mining operations, battery plants, paints and dyes, photography, perfumes and cosmetics, and chemical laboratories. It is poisonous by ingestion through food and intraperitoneal routes. Calomel is moderately toxic by skin contact. When heated to decompose, it emits very toxic fumes of Cl and Hg. 

There is a little information on the particle size distribution of acid mists in occupational settings. Van Dusen and Smith (198) reported particles ranging in size from 0.5 to 39 pm in their study on electrowinning of metals. Gamble et al. (206) measured mean exposures to sulfuric acid of 0.18 mg/m at an average MMAD of close to 5 pm in their study of health effects of sulfuric acid in lead-acid battery plants. 

The Neurobehavioral Evaluation System 2 (NES2) is a neurobehavioral evaluation system designed to facilitate screening of populations at risk of nervous system damage due to environmental agents. This evaluation system is administered on a microcomputer. Epidemiologic research influenced the sets of tests that were included in this battery. An expert committee convened by the World Health Organization (WHO) and the National Institute for Occupational Safety and Health (NIOSH) proposed a set of core tests for this battery. Many of the core tests that were... 

Two different test batteries, the World Health Organization (WHO) Neurobehavioral Core Test Battery and the Neurobehavioral Evaluation System (NES), are currently the most widely used test batteries in occupational behavioral toxicology studies. Both include components of the WAIS described previously in addition to other psychometric tests of behavioral function. The WHO Neurobehavioral Core Test Battery is a pencil and paper-administered test battery, whereas the NES is a computerized test battery that has been translated into several languages and in fact presents a more extensive set of tests than does the WHO in that it includes tests of psychomotor performance, cognition, memory and learning, and perceptual ability and affect.
