beryllium plant collected

Beryllium is a naturally occurring element that is extracted from ores and processed into metal, oxides, alloys, and composite materials. Industrial use of beryllium, such as machining metal parts, can lead to BeS and CBD ().The major applications of beryllium are in automotive electronics, telecommunications, computers, aerospace, and defense equipment ().

Pond (BSFAP) associated with the Big Sandy Power Plant located in Louisa, Kentucky (Figure 1). This ASD has been prepared per the requirements of the United States Environmental Protection Agency (USEPA) Coal Combustion Residual (CCR) Rule ( 40 Code of Federal Regulations [CFR] ).

Water Treatment System Samples Metals were not detected above MCLs in any of the samples collected on December 30, 2008. The following metals (with MCLs) were not detected in the samples collected from the water treatment systems: mercury, antimony, arsenic, beryllium, cadmium, chromium, lead, selenium, and thallium.

BERYLLIUM PROGRAM AT HANFORD Beryllium is a lightweight, durable metal that has wide spread industrial applications. The use of beryllium at the Hanford site during fuel element production, and maintenance of selected industrial components and tools, has resulted in potential occupational beryllium exposure to current and former employees.

In classifying the hazards of beryllium, at least the following hazards must be addressed: Cancer; lung effects (CBD and acute beryllium disease); beryllium sensitization; skin sensitization; and skin, eye, and respiratory tract irritation.

Beryllium is a lightweight but extremely strong metal used in the aerospace, electronics, energy, telecommunications, medical, and defense industries. Berylliumcopper alloys are widely used because of their electrical and thermal conductivity, hardness, and good corrosion resistance. Beryllium ...

A4 Aquatic Life Toxicology* INTRODUCTION The available data base for the effects of beryllium on fresh water organisms is limited to seven species of fishes, two species of salamanders, one invertebrate species, and one green alga. Chronic test data are not available for any species of fish.

We provide highperformance products and technologies for applications in a wide range of demanding markets: Aerospace, Automotive, Computer/Telecom, Foundry, Manufacturing ...

Quantitative beryllium exposure data are available for 325 jobs in one plant Reading (OH, USA). The most interesting early periods had to be extrapolated on relatively few analyses performed between 1947 and 1970. Executive summary:

Longterm (>120 min) and shortterm (120 min) personal and area samples were collected during a variety of activities including machining of copper berylliumcontaining parts, as well as finishing operations (, deburring and polishing) and decontamination of machinery. A total of 580 beryllium air samples were analyzed (311 personal and 269 area samples).

• Hazardous air pollutants, such as arsenic, beryllium, cadmium, chromium, lead, manganese, nickel, radium, selenium, and other metals, are integral components of fine particulate matter emitted directly from coalfired power plants. • The metal content of fine particulate matter has been linked to cardiovascular public health impacts

Methods Airborne beryllium concentrations had been measured using allglass impingers, highvolume air filters, and personal respirable and total dust samplers. To provide consistency in exposure estimates over time, measurements collected by the other monitoring methods were converted to approximate the most frequently used highvolume, timeweighted average measurements.

Presence of spherical uranium microparticles with fluorine and oxygen in samples, collected at the plant or near the plant, specifies the process of uranium isotopes' separation in a uranium hexafluoride. Most of these spherical particles have sizes from 1 m to 2 m. Such typical particle is shown on photo 3. Photo 1. Aerosol uranium microparticle

The International Agency for Research on Cancer (IARC) has found that the evidence for the carcinogenicity of beryllium is sufficient based on animal data but "limited" based on human data. This analysis reports on a retrospective cohort mortality study among 9,225 male workers employed at seven beryllium processing facilities for at least ...

Former workers at risk from exposures while working at Pantex are offered a free medical screening. This project is carried out by Drexel University School of Public Health in conjunction with the University of Texas Health Science Center at Tyler.

In this work, 7Be was determined in leaves of 10 plant species collected from streets, parks and open land and in 5 consecutive rains over Alexandria, Egypt. 7Be levels were also measured in soil covered by each type of plant as well as in the nearest uncovered soil to be reference values to determine its intercepted amount and consequently

solvents, acids, and metals. American Beryllium collected wastewater in a holding pond on the southeast comer of the site (DEP 1994). In 1996, LockheedMartin purchased the American Beryllium facility and ceased operations. In 2004, both the Florida DOH and LockheedMartin's consultant tested drinking water wells and irrigation wells at nearby homes.

The total number of beryllium samples collected by the industrial hygiene staff at the plant varied considerably by decade . In the 1960s, when beryllium operations were first implemented, 4 personal and 174 area samples were collected.

Approximately 500,000 FAH samples were collected for beryllium over three decades. From 1984 to 1987, personal breathing zone (PBZ) samples were also collected as part of the evaluation of a new high velocity/low volume local exhaust ventilation (HV/LV LEV) system.

Beryllium was detected in 87% of samples collected at the munitions plant and in 72% of the samples collected at regional reference sites. Two munitions plant samples from areas near sanders and grinders were above micro g/100 cm(2) ( Department of Energy surface contamination limit).
