While chemical warfare agents have been used in military conflict for decades, it is only in the last two decades that increased attention has been paid to the acute and chronic health effects associated with exposure to these agents. The subsequent reports of ill-defined illnesses in the veterans of the Gulf War of 1991, followed by the 1995 sarin terrorist attack in the Japanese subway system...
BACKGROUND Lack of information and accurate knowledge about the properties of chemicals and the exposure derived from its use; hinder health and safety measures to protect exposed workers. The aim of this study is to identify the elements that will help us draw a balance of chemical hazards in Spain and register the most dangerous chemicals at the workplace (by sector or field of activity). M...
OBJECTIVES The aim of this study is to assess preserved umbilical cords as chemical exposure media to investigatein utero chemical exposure. Furthermore, we aim to apply preserved umbilical cords to retrospective studies of the relationship betweenin utero chemical exposure and neurodevelopment disorders. METHODS Two sets of preserved umbilical cord samples were analyzed for exposure to polyc...
BACKGROUND Several chemical UV filters/absorbers ('UV filters' hereafter) have endocrine-disrupting properties in vitro and in vivo. Exposure to these chemicals, especially during prenatal development, is of concern. OBJECTIVES To examine maternal exposure to UV filters, associations with maternal thyroid hormone, with growth factor concentrations as well as to birth outcomes. METHODS Prosp...
Before the 1970s, the United States sometimes disposed of at sea excess, obsolete, or unserviceable munitions, including chemical munitions. Chemical munitions known to have been disposed of at sea included munitions filled with sulfur mustard, a vesicant (i.e., an agent that causes chemical burns or blisters of the skin and mucous membranes). Signs and symptoms of exposure to a mustard agent c...
Background & Aims: Cancer is a major health problem worldwide. Several factors are involved in cancer. However the role of environmental factors is more prominent. Modification of these factors into proper behavior would help to prevent cancer. Accordingly this study was done with the aim of evaluating the exposure to carcinogenic agents in Tehran citizens. Material & Methods: It was a desc...
OBJECTIVES A hazard assessment of di(2-ethylhexyl) phthalate (DEHP), a commonly used workplace chemical, was conducted in order to protect the occupational health of workers. A literature review, consisting of both domestic and international references, examined the chemical management system, working environment, level of exposure, and possible associated risks. This information may be utilize...
Background and Aims: n-hexane is widely used in the production of glues, lacquers, paints, plastic, and rubber products. Therefore, a significant potential for exposure to this toxic solvent exists in industrial settings. This study was carried out to assess the exposure to n-hexane and to determine the correlation between this exposure and urinary concentration of free 2,5-hexanedione (2,5-H...
Background and Aims Ethylene oxide is used as a sterilizing agent in health care industries. The present study aimed to assess and recognize the nature of pulmonary reactions, if any, associated with occupational exposure to ethylene oxide and to investigate the prevalence of dermal, visual, neurologic, reproductive, hematologic, hepatic and renal disorders . Methods Forty exposed and 47 u...
Several different meanings have been attached to the term "chemical sensitivity" by those who use it. Feeling ill from odors is a symptom reported by approximately one-third of the population. The syndrome of chemical sensitivity, frequently called "Multiple Chemical Sensitivity" or "MCS" has been the subject of three federally-sponsored workshops; at least five different case definitions for r...
