  • pollution
  • Epidemiological studies have shown that the low levels of air pollution in most industrialised societies are still linked to adverse health outcomes. (bmj.com)
  • Studies of the long term effects of air pollution have been carried out in large cohorts. (bmj.com)
  • Some governmental regulatory jurisdictions require industrial sources of air pollution to comply with sea level standards corrected for altitude. (wikipedia.org)
  • In other words, industrial air pollution sources located at altitudes well above sea level must comply with significantly more stringent air quality standards than sources located at sea level (since it is more difficult to comply with lower standards). (wikipedia.org)
  • Due to its preexisting standards and particularly severe motor vehicle air pollution problems in the Los Angeles metropolitan area, the U.S. state of California has special dispensation from the federal government to promulgate its own automobile emissions standards. (wikipedia.org)
  • The Ventura County Air Pollution Control District (VCAPCD), formed in 1968, is the air pollution agency responsible mainly for regulating stationary sources of air pollution for Ventura County. (wikipedia.org)
  • The District was formed by the Board of Supervisors in response to the county's first air pollution study which identified Ventura County as having a severe air quality problem. (wikipedia.org)
  • The VCAPCD is governed by the Air Pollution Control Board. (wikipedia.org)
  • They also appoint the Air Pollution Control Officer, the District Hearing Board, Advisory Committee, and Clean Air Fund Advisory Committee. (wikipedia.org)
  • The Air Pollution Control Officer (APCO) of the VCAPCD reports to the APC Board and the following divisions report to the APCO: The VCAPCD has a staff of about fifty employees including inspectors, engineers, planners, technicians, and support staff. (wikipedia.org)
  • The Hearing Board consists of five members appointed by the Air Pollution Control Board for three-year terms. (wikipedia.org)
  • Current members are: Gary Gasperino - Engineering (Chair) Stephen C. Hurlock, Ph.D - Public (Vice Chair) Daniel J. Murphy - Law Mike Stubblefield - Public The VCAPCD Advisory Committee is a twenty-member citizens advisory body appointed by the Air Pollution Control Board. (wikipedia.org)
  • The Committee reviews staff proposed new and revised rules, and makes recommendations to the Air Pollution Control Board on those rules. (wikipedia.org)
  • Air quality regulation must identify the substances and energies which qualify as "pollution" for purposes of further control. (wikipedia.org)
  • While specific labels vary from jurisdiction to jurisdiction, there is broad consensus among many governments regarding what constitutes air pollution. (wikipedia.org)
  • A broader conception of air pollution may also incorporate noise, light, and radiation. (wikipedia.org)
  • Such standards generally are expressed as levels of specific air pollutants that are deemed acceptable in ambient air, and are most often designed to reduce or eliminate the human health effects of air pollution, although secondary effects such as crop and building damage may also be considered.

  • urine
  • The sampling was done concurrently, taking the urine and alveolar air samples before and after the work shift for 15 workers and the swimming activity for 12 swimmers. (biomedsearch.com)
  • A high THM uptake was observed in alveolar air and urine of subjects exposed, with chloroform being the most abundant THM. (biomedsearch.com)
  • After 1 h swimming, the increases found in swimmers were ca. 20 and 3 times in alveolar air and urine, respectively. (biomedsearch.com)
  • In response to concerns about the town's air quality, the Texas Department of State Health Services conducted air quality tests, and in May 2010, released its results for DISH, including tests of blood and urine samples from 28 DISH residents that were tested for volatile organic compounds (VOCs). (wikipedia.org)
  • nitrogen
  • Nitrogen dioxide is an irritant of the mucous membrane linked with another air pollutant that causes pulmonary diseases such as OLD, asthma, chronic obstructive pulmonary disease and sometimes acute exacerbation of COPD and in fatal cases, deaths. (wikipedia.org)
  • indoors
  • We discuss the potential advantages, limitations and developments needed, so that PAS can be used reliably and routinely indoors and in occupational settings for POPs. (rsc.org)
  • regulations
  • Such states are frequently referred to as "CARB states" in automotive discussions because the regulations are defined by the California Air Resources Board. (wikipedia.org)
  • 6.6 million in 2006 dollars) for the analysis of air regulations. (wikipedia.org)
  • effects
  • With this approach, the effects of some air pollutants could be correlated with biological endpoints from the Comet assay. (bmj.com)
  • Much of the recent epidemiology has been based on time-series studies of large urban populations, although there are also a number of small panel studies of groups that may be more susceptible to the effects air pollutants. (bmj.com)
  • regulation
  • The United States Environmental Protection Agency (responsible for air quality regulation at a national level under the U.S. Clean Air Act, utilizes performance standards under the New Source Performance Standard (NSPS) program. (wikipedia.org)
  • Workplace
  • On the other hand, employers may be required immediately to rectify any violation of OSHA workplace air quality standards. (wikipedia.org)
  • levels
  • Experimental and computational methods were used to provide information about the pollutant distribution in the vicinity of the human body for different levels of room air mixing. (cdc.gov)
  • The town spent $15,000 on an air quality test, which found elevated levels of several chemicals including benzene. (wikipedia.org)
  • standards
  • Two sets, or tiers, of emission standards for light-duty vehicles in the United States were defined as a result of the Clean Air Act Amendments of 1990. (wikipedia.org)
  • Another set of standards, for indoor air in employment settings, is administered by the U.S. Occupational Safety and Health Administration. (wikipedia.org)
  • reference
  • TEOM instruments with FDMS alternate between a base cycle and a reference cycle, the latter of which measures the mass loss of the filter when clean air is passed through it, allowing the mass loss during the base cycle to be estimated. (wikipedia.org)
  • water
  • Environmental monitoring of THMs in water and ambient air was also performed in order to assess the possible correlation between environmental and biological samples. (biomedsearch.com)
  • In addition, water droplets cannot be distinguished from particle mass, so the device must adjust the incoming air temperature to cause water droplets to evaporate, or contain a dryer or humidity sensor to adjust the readings. (wikipedia.org)
