  • The invisible fine dust

    Air is lifeblood. Daily we inhale approximately 15.000 liter. Still, the air contains invisible pollutants, which vary in its composition and concentration depending on the location. Especially the respirable particles with a diameter of less than 2.5 µm (PM 2.5) were considered to be particularly dangerous. According to a current study conducted by the Max Planck Society, ...

  • Down with road dust

    There are more than 3.9 million miles of roadway in the United States, according to the Federal Highway Administration, and, depending on the area of the country you're in, as much as 70% of that road mileage is unpaved. The 1997 U.S. Environmental Protection Agency (EPA) National Air Quality and Emissions Trends Report states that those unpaved roads--which can cover a wide range of ...

  • Assessment of bagging operators exposure to with pvc airborne particulates

    The hazard potential of airborne particles is dependent on the mass concentration as well as the particle size. Particle size determines the deposition site within the respiratory tract and the subsequent health effects. Particle-size is considered from two viewpoints: The sizefraction most closely associated with the specific health effect, and the mass concentration within that size fraction. ...

  • Risk assessment and brownfields-determining exposure to site contaminants

    The USEPA’s Brownfields Program was developed to facilitate the rehabilitation of contaminated property for re-development. EPA has set forth criteria that must be met for a revitalized property to be used for residential, commercial or industrial purposes. The main thrust of these criteria is the long-term protection of residents or visitors (including shoppers and business employees). As ...

  • Effective Industrial Dust Collector Strategies

    Finding the correct type of industrial dust collector for the grinding section is a must for opposing an injection mold creating shop. This is vital for health and welfare of workers and for the performance of grinding machines. Dusts produced from electrodes are graphite and copperand during the milling or grinding operation, these needs to be filtered away from the atmosphere with an ...

  • Controlling Dust and Bioaerosols at a Biosolids Composting Faclity

    Studies at enclosed Longmont, Colorado project evaluate exposure level of employees. Operational changes reduce dust, endotoxin and A. Fumigatus by 90 percent. WHEN dealing with public health issues and composting, attention has been predominantly focused on potential exposure from the release of Aspergillus fumigatus (A. fumigatus) from composting facilities. Numerous studies were conducted to ...


  • How to deal with asbestos exposure in your workplace: advice for industrial workers

    At one point, more than 75 different industries exposed workers to asbestos. Even though these industries have been made safer by regulations from the National Institute for Occupational Health and Safety, many workers still come in contact with asbestos products that remain at their jobsites. Although most industrial employees face some form of asbestos exposure risks during their career, ...

  • Effect of salinity on the toxicity of road dust in an estuarine amphipod Grandidierella japonica

    Urban runoff can reach coastal aquatic environments; however, little is known about the effect of salinity on road runoff toxicity. The objective of this study is to investigate the toxicity of highway road dust over a salinity gradient from 5 to 35‰, in an estuarine benthic amphipod, Grandidierella japonica. Road dust toxicity was evaluated by assessing mortality after 10 days of exposure ...
