  • Environmental risk assessment of human pharmaceuticals: Regulatory developments

    Concern about the potential environmental impact of pharmaceutical residues in the aquatic environment was first expressed over 30 years ago. It is therefore surprising that there is still so little current regulation requiring environmental risk assessments to be undertaken on human pharmaceuticals. Particularly in view of the rapid development in legislation, that has taken place in many ...

  • Comparative Risk Assessment

    ' Comparative risk assessment provides a systematic way to compare environmental problems that pose different types and degrees of health risk. It combines information on the inherent hazards of pollutants, exposure levels and population characteristics to predict the resulting health effects. Using data from available sources, rapid, inexpensive comparative risk assessments can identify the most ...

  • How to make top-down and bottom-up sustainability converge

    Fits and starts are all too common in the sustainability world. One year you have budget for initiatives; the next you don’t. Management hails cost savings on individual projects, but they miss the big picture and fail to link progress across departmental boundaries. Bottom-up progress and top-down directives pass each other like proverbial ships in the night. But it doesn’t have to ...

  • Ecological Risk Assessment

    In recent years, ecological risk assessment (ERA) has emerged as an important part of environmental protection programs. The following discussion provides a brief overview of ERA issues. What is ecological risk assessment? Ecological risk assessment is the practice of determining the nature and likelihood of effects of our actions on animals, plants, and the environment. ...

  • Transformational adaptation – when climate change means business as usual is no longer possible

    1. A lesson from the past Deep in the central Sahara, a crumbling mud-brick town sits at the edge of a dry lake bed. This is the medieval town of Germa, in southwestern Libya, one of a string of settlements along the Wadi al-Ajal, a valley defined by the towering dunes of the Ubari Sand Sea to the north, and the black cliffs of the Messak Settafet plateau to the south. Germa is romantic ...

  • Nanopharmaceuticals – tiny challenges for the environmental risk assessment of pharmaceuticals

    Many new developments and innovations in health care are based on nanotechnology. The field of nanopharmaceuticals is diverse and not as new as one might think: for many years nanopharmaceuticals have been marketed and future is likely to bring more nanosized compounds to the market. Therefore it is time to examine, whether the environmental risk assessment for human pharmaceuticals is ...

  • Ecosystem services as assessment endpoints for ecological risk assessment

    Ecosystem services are defined as the outputs of ecological processes that contribute to human welfare or have the potential to do so in the future. Those outputs include food and drinking water, clean air and water, and pollinated crops. The need to protect the services provided by natural systems has been recognized previously, but ecosystem services have not been formally incorporated into ...

  • Gas station risk assessment closure

    On behalf of a local developer, Troy Risk successfully obtained a No-Further-Action certification from the State environmental agency IDEM in just several months. The site historically operated as a gas station. Several subsurface investigations at the site confirmed that soil was impacted from an old petroleum release. The release was discovered in 1994 during collection of soil and groundwater ...

  • Sensitivity Analysis with Correlated Inputs – an Environmental Risk Assessment Example

    ABSTRACTCrystal Ball® calculates sensitivities by computing rank correlation coefficients between model inputs (assumptions) and outputs (forecasts) – an approach that is known to provide inaccurate results for correlated assumptions. This  paper describes the Partial Correlation Coefficient (PCC) concept for sensitivity analysis of probabilistic models with correlated inputs. PCCs quantify ...

  • Reflections on new directions for risk assessment of environmental chemical mixtures

    Currently risk assessment of chemicals tackles them as single substances affecting individual health endpoints. In reality, human exposure occurs to mixtures of chemicals, as they are present in the environment and consumer products. Combining the information from environmental fate analysis, epidemiological data and toxicokinetic/dynamic models helps estimate internal exposure. Coupling these ...

  • Combining exposure and effect modelling into an integrated probabilistic environmental risk assessment for nanoparticles

    There is a growing need for good environmental risk assessment of engineered nanoparticles (ENPs). Environmental risk assessment of ENPs has been hampered by lack of data and knowledge about ENPs, their environmental fate and their toxicity. This leads to uncertainty in the risk assessment. To effectively deal with uncertainty in the risk assessment, probabilistic methods are advantageous. In ...

  • Use of acute and chronic ecotoxicity data in environmental risk assessment of pharmaceuticals

    For many older pharmaceuticals, chronic aquatic toxicity data are limited. To assess risk during development, scale‐up and manufacturing processes, acute data and physicochemical properties need to be leveraged to reduce potential long‐term impacts to the environment. Aquatic toxicity data were pooled from daphnid, fish and algae studies for 102 active pharmaceutical ingredients (APIs) to ...

  • Tenax extraction as a simple approach to improve environmental risk assessments

    It is well documented that using exhaustive chemical extractions is not an effective means of assessing exposure of hydrophobic organic compounds in sediments and that bioavailability‐based techniques are an improvement over traditional methods. One technique that has shown special promise as a method for assessing the bioavailability of hydrophobic organic compounds in sediment is the use of ...

  • The Development of Integrated Databases For Environmental And Natural Risk Assessment in The Area of The Tisza River

     In the frame of the mission of the Joint Research Centre, the work of the Land Management and Natural Hazards Unit (LMNHU) aims to improve: • the understanding and prediction of regional changes in climate and extreme weather events;• the quantification of climate change impacts at the continental, regional, and local levels;• the analysis of adaptation and risk mitigation activities;• the ...


  • An Introductory Guide to Uncertainty Analysis in Environmental and Health Risk Assessment

    EXECUTIVE SUMMARYThis report presents guidelines for evaluating uncertainty in mathematical equations and computer models applied to assess human health and environmental risk. Uncertainty analyses involve the propagation of uncertainty in model parameters and model structure to obtain confidence statements for the estimate of risk and identify the model components of dominant importance. ...
