  • Proof of concept for the use of macroinvertebrates as indicators of PCB contamination in Lake Hartwell

    The U.S. Environmental Protection Agency (EPA) develops methods and tools for evaluating risk management strategies for sediments contaminated with polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and other legacy pollutants. Monitored natural recovery (MNR) is a risk management alternative that relies on existing physical, chemical, and biological processes to ...

  • Effectiveness of a Sediment Time Critical Removal Action – PCB Reduction in Fish Tissue, Surface Water and Sediment via Wet Excavation

    Documenting successful remediation of polychlorinated biphenyl (PCB)‐contaminated sediments is limited; potentially due to inadequate monitoring methods, complexities associated with the environment, and selected remedial techniques. At some sites, absence of appropriate baseline and post‐removal monitoring limits proper evaluation of remedial efficacy. Accurate interpretation of interactions ...

  • Predictors of mercury spatial patterns in San Francisco Bay forage fish

    Pollution reduction efforts should be targeted towards those sources that result in the highest bioaccumulation. For mercury (Hg) in estuaries and other complex water bodies, carefully designed biosentinel monitoring programs can help identify predictors of bioaccumulation and inform management priorities for source reduction. We employed a probabilistic forage fish Hg survey with hypothesis ...

    The announcement earlier this year that BMW Group is investing a further £100 million to increase production at its Oxford plant is good news for those buyers who have been waiting around three months to get their hands on the steering wheel of the legendary new MINI. In the paint shop, this poses a special challenge – how do you reconcile the demands of more throughput, less maintenance downtime ...

  • Impacts of Climate Change on the Occurrence of Harmful Algal Blooms

    Climate change has been occurring naturally as well as caused by anthropogenic activities over the decades. In relation to the fresh and marine water, the concentration of greenhouse gases results in temperature rise of surface water, lower pH and changes to precipitation, evaporation and vertical mixing of water. All these consequences of changing the environment in combination with excessive ...

  • Ionising Radiation

    Introduction The energy level of some types of radiation is high enough so that when they interact with matter they cause the formation of electrically charged particles or ion-pairs and break molecular bonds. These so-called ionising radiations are by their nature potentially harmful to life; at high doses they can be lethal and at lower doses can cause genetic damage. Ionising radiation occurs ...

  • Minimising Risks to Air Quality and Regulatory Compliance With Total Filter Management

    It has been shown in recent studies that as much as 25% of the total site operating budget (excluding raw material costs) for a typical medium-large dosage-form manufacturing facility will be spent on compliance measures for internal quality systems and external regulatory activities. (1) Market realities indicate that the pharmaceutical companies will need to address the overall cost of ...
