Atrazine has been identified in at least 20 of the 1,636 hazardous waste sites that have been proposed for inclusion on the EPA National Priorities List (NPL) (HazDat 2003). However, the number of sites evaluated for atrazine is not known. The frequency for these sites within the United States can be seen in Figure 6-1. Of these sites, all 20 are located within the United States and none are lo...

AIMS To determine the relation of the inhalation and dermal exposure routes and mutagenic activity in the urine of rubber workers (n = 105). METHODS Mutagenic activity of ambient total suspended particulate matter (TSPM), surface contamination wipes, and Sunday and weekday urine samples was assessed with S typhimurium YG1041 in the presence of a metabolic activation system. Each subject was g...

introduction: nosocomial infections affect nearly 10% of hospitalized patients. the majority of nosocomial infections are transmitted by contact, primarily by hands of health care workers. the micro-organisms on the hand can be divided into transient, resident and infectious flora. transient flora is the main cause of nosocomial infection which acquired primarily by contact and loosely attached...

background the prognostic value of blood culture testing in the diagnosis of bacteremia is limited by contamination. objectives in this multicenter study, the aim was to evaluate the contamination rates of blood cultures as well as the parameters that affect the culture results. materials and methods sample collection practices and culture data obtained from 16 university/research hospitals wer...

Abstract This study aimed to determine the influence of storage on structural damage vegetable-tanned goat skin by microbes. The time was divided into three treatments, namely treatment P0 (0 months, storage), P1 (6 and P2 (12 storage). observation parameters for investigation included microbe contamination, pH levels, levels oil/fat. conducted with Analysis Variance Completely Randomized Desig...

Background Contamination of sterile pharmaceutical products can have serious consequences, in worst case scenario resulting patient death. Cleanroom operators are the primary source microbial contamination, where surface their specialist clothing garments is subject to such contamination during wear. In turn these become a transmission vector for microorganisms within cleanroom environment. Ins...
