Washington, D.C.-area

In the Washington, D.C. area, in cooperation with television station WJLA-TV, we measured 52 residential buildings, which were located in 9 towns in northern Virginia and in 22 towns in Maryland. Three residential buildings in Washington, D.C. were also included. 

The U.S. Office of Technology Assessment notes that an aerosol attack on the Washington, D.C. area could yield as many as three million casualties. Other sources suggest approximately 500,000 casualties from a less ambitious attack. 

It is widely believed that vegetation growing in the humid eastern United States would be severely injured if oxidant concentrations reached the daily peak concentrations (0.20-0.40 ppm) commonly experienced in the less humid sections of California. An air pollution episode that occurred on July 27-30, 1970, in the Washington, D.C., area is indicative of what may happen. During this 4-day period, the peak oxidant concentrations ranged from 0.14 to 0.22 ppm and were accompanied by a low concentration of sulfur dioxide (0.04 ppm). Oxidant injury was observed on 31 tree, 15 shrub, and 18 herbaceous species in an area of 72 mi (about 187 km ). Increased emisskm of the precursors of photochemical-oxidant formation could result in repeated episodes of acute injury or even chronic injury to eastern vegetation. 

In October 2002, the Washington, D.C.-area snipers who killed 10 people and wounded four brought a new kind of gun terror to the populace. Unlike earlier mass shootings that were horrific but brief in duration, in this instance the killing of people seemingly at random went on for almost a month, with law enforcement officials appearing to be baffled and the targets essentially defenseless. 

Gun control groups also began to focus on so-called sniper rifles as another form of terrorist threat. The Washington, D.C.-area sniper shootings... 

October Ten random persons are killed and three injured by Washington, D.C. -area anonymous snipers. The shootings, revealed later to have been done with a high-powered Bushmaster rifle by Lee Boyd Malvo and John Allan Muhammad, are used by gun control advocates to argue for extending and expanding the bans on such weapons. 

March 9 John Allan Muhammad, considered the mastermind behind the Washington, D.C.-area sniper killings in October 2002, is sentenced to death. The following day his young accomplice, Lee Boyd Malvo, receives a life sentence without possibility of parole.

The purpose of this study was to compare two electrophoretic methods used to type EAP and to examine the stability of EAP phenotypes in red cell hemolysates, clotted blood and dried bloodstains stored at room temperature (25°C). A distribution study of the frequency of five EAP phenotypes among ABO, MN, Rh blood groups and among 137 metropolitan Washington D. C. area residents was made. The effect of neuraminidase on EAP was also studied. 

Preparation of samples. Fresh and outdated blood samples used in this study were obtained from blood banks of selected medical institutions in the metropolitan Washington, D. C. area. 

Distribution of five EAP phenotypes among a randomly selected number of metropolitan Washington, D. C. area residents and among the ABO, MN and Kh blood groups. The incidence of five EAP phenotypes m 137 randomly selected negro and Caucasian metropolitan Washington, D. C. area residents is shown in table 2. The computed frequencies of 10.2% type A, 44.5% type B,... 

Within the past several decades, considerable field work has been done using sodium silicate solution and organic reactants without accelerators. Much of this relates to vehicular tunnels in the Washington, D.C. area and is well documented [8]. Contractors field charts demonstrate gel times of the grout in Fig. 11.5. 

About a third of the agency s employees are stationed outside of the Washington, D.C., area in over 150 field offices and laboratories, including five regional offices and 20 district offices.
