The Environmental Protection Agency (EPA) identifies the most serious hazardous waste sites in the nation. 447-462. exposure to benzene was likely to affect less than 10 people in Hamilton and Dunedin, less than 40 people in Christchurch and less than 70 people in Auckland. The National Institute of Environmental Health Sciences (NIEHS) is the principal federal agency for biomedical research on the effects of chemical, physical, and biologic environmental agents on human health and well-being. Alexander Drive, Research Triangle Park, NC 27709 • Phone: 919-541-3212. Details. Data from EPA's TEAM Study allow us to identify the major sources of exposure to benzene for much of the U.S. population. Multiple studies have shown that EO increases the risk of several types of cancer. This review focuses on the available … In order for it to cause any adverse health effects, you must come into contact with it. The evaluation and review of the noncancer effects of exposure to benzene have been conducted under the U.S. Environmental Protection Agency's standing guidance of several relevant risk assessment guidelines dealing with reproductive, developmental, and Biological monitoring plays an important role in exposure assessment of workers occupationally exposed to chemicals. Recent studies have increasingly focused on environmental exposures, including benzene. What Are the Health Effects of Benzene? Analysis of the partition ing of benzene, toluene, and MTBE from gasoline Benzene is also present in petroleum products used to manufacture such common products as plastics, nylon, Styrofoam, rubber, dry cleaning solvents . Ethylene oxide (EO) is an environmental pollutant and is toxic to humans. Background: Exposure to benzene has been associated with adverse health effects, including haematopoietic disorders. Benzene has long been recognised as a carcinogen and recent concern has centred on the effects of continuous exposure to low concentrations of benzene both occupationally and environmentally. These documents provide information on the health effects of exposure, the chemical's toxicity and material for responding to a chemical incident. The main aim is to contribute to environmental health protection, and special attention is directed to monitoring the hazard posed by benzene (as a carcinogenic agent model) mainly because its ubiquitous presence often leads to severe noxious effects in humans among whom increased rates of human leukemia have been reported. Exposure can occur occupationally, in the general environment and in the home as a result of the ubiquitous use of benzene-containing petroleum products, including motor . Environmental. Hectares of forests cut down or burned. EWG's Skin Deep rates thousands of personal care product ingredients, culled from ingredient labels on products, based on hazard information pulled from the scientific literature and industry, academic and regulatory databases. Gasoline is a mixture of about 150 chemicals refined from crude oil. Off-gassing from building materials and structural fires lead to increased atmospheric benzene levels. US EPA, 2001. Benzene, a volatile organic compound (VOC) and a hazardous air pollutant, is a byproduct of the petroleum refining process. • benzene vapour may cause eye irritation at high concentrations Casualty decontamination at the scene • following disrobe, improvised dry decontamination should be considered for an incident involving benzene unless casualties are demonstrating signs or symptoms of exposure to caustic or corrosive substances Environment Long-term health effects of exposure to benzene . Methods: A retrospective cohort study was carried out from the beginning of April 2017, through the end of June 2018, on 280 taxi drivers (the exposed . Objectives: To study environmental exposure to benzene as well as hematological effects of benzene exposure in taxi drivers. Consensus review draft, July 2001. Acute high exposures may cause damage to the central . Overall significance of this work: a. These sources turn out to be quite different from what had previously been considered the important sources. This paper presents an overview of the current knowledge about human exposure to benzene in the United Kingdom population based on recently published data, summarises the known human health . Objectives . (Long-term exposure means exposure of a year or more.) In humans, benzene crosses the placenta and is present in the cord blood in amounts equal to those in maternal blood (Dowty et al., 1976); however, studies of the effects of benzene on human reproduction and development have been confounded by the presence of other chemicals in the environment (USAF, 1989). The RfC is an inhalation exposure concentration at or below which adverse health effects are not likely to occur. 077; Coal naphtha; Cyclohexatriene; NCI-C55276; Phene; Phenyl hydride; Polystream; Pyrobenzol; EPA Pesticide Code . Benzene is a toxic chemical that occurs naturally in the environment but is also used by man in a wide range of products. This study focuses on the effects of soil composition and temperature on the sorption and desorption . Contact: NIEHS, PO Box 12233, 104 T.W. A retrospective cohort study was carried out from the beginning of April 2017, through the end of June 2018, on 280 taxi drivers (the exposed . Specifically, benzene causes bone marrow suppression and, through its metabolites, disruptions in the cell cycle which can lead to mutagenesis. All those pieces of furniture require enormous amounts of trees, plastic, cotton and other materials. • Tobacco smoke is a major source of benzene particularly in indoor air Benzene released in the outdoor air breaks down within a few days and does not build up in plants or animals. At low concentrations, the health effects benzene produces are mainly The EPA classified the chemical as a human carcinogen in 2016. Human health effects due to exposure to benzene. Air quality goal. environment. Overview Health effects Environmental effects Sources of emissions References Description Ethylbenzene is used primarily in the production of styrene and synthetic polymers. Automobile exhaust accounts for the largest source of benzene in the general environment. Benzene is considered to be a cancer-causing chemical. Benzene affects many organ systems. 22,803,424.79. Although benzene intake may occur via the diet or through skin absorption, the inhalation route is the most important. These are known as the BTEX compounds. Benzene 8.0E-02 Depressed lymphocyte count in humans MediumCentral nervous system depression in humans . The most important source of exposure for 50 million smokers is the mainstream smoke from their cigarettes, which accounts for about half of the total population . Here are some fascinating facts about benzene and some hints on how you can help minimise any harmful effects of benzene on our health and on the environment. The health effects caused by exposure to 1,3-butadiene can be split into two categories: acute and chronic. This highlights the inter-relationship between motoring, outdoor air, indoor air and smoking. spawning may also be exposed to environmental extremes, particularly to changes in salinity, which produce additional stress. Benzene (C6H6) is a highly flammable, colorless liquid that evaporates quickly into the air. Benzene causes harmful effects on the bone marrow and can cause a decrease in red blood cells, leading to anemia. The environmental impact of furniture. 18. Health effects of CO, NO 2, SO 2, ozone, benzene and benzo(a)pyrene in New Zealand vii Benzene has been classified as a group 1A carcinogen ( 5 ), as its toxic effects on the hematopoietic system are well known ( 39 ). and effects of benzene on the Canadian environment have been emphasized. The The hematopoietic system and immune system are among the affected systems. STRUHSAKERl ABSTRACT . Benzene has long been recognised as a carcinogen and recent concern has centred on the effects of continuous exposure to low concentrations of benzene both occupationally and environmentally.
