  • Keeping Healthcare/SPD Workers Safe from Exposure: 2 Very Different Options

    Continuous Monitoring vs. Badges Badges are designed to provide the Time Weighted Average (TWA) data for the total exposure period. They contain an absorption medium that reacts with or absorbs and holds the target chemical from the air to be analyzed later, which indicates the exposure after the fact. Badges, sample tubes, and wet chemical methods were the predominant technologies for monitoring ...

  • Skid Systems - Case Study

    A Chemical Metering Pump is seldom used by itself. It is usually a part (ok, the part) of a chemical injection system into a process. Such a system requires various accessories, valves and controls to dispense the exact amount of chemical demanded by the application which may itself vary. Let us say if you are using chemical pump to achieve pH balance for the water. You need to measure the pH of ...

  • Warehouse Optimization: Balancing Equipment Performance and Worker Safety Through Emissions Measurements and Air Quality Monitoring

    Successful warehouse functionality is dependent on both maximizing equipment performance and providing a safe and healthy environment for workers that encourages productivity. However, these two factors are often at odds with each other as warehouse equipment such as forklifts, burnishers and delivery trucks emit toxic gases that can have the potential to create poor indoor air quality which ...

  • Chemical and biochemical characterization and in vivo safety evaluation of pharmaceuticals in drinking water

    The water constituents that are currently subject to legal control are only a small fraction of the vast number of chemical substances and microorganisms that may occur in both the environment and in water resources. The main objective of this work is to study the health impact resulting from exposure to a mixture of pharmaceuticals that have been detected in tap water at low doses. Analysis ...

  • A tiered, integrated biological and chemical monitoring framework for contaminants of emerging concern (CECs) in aquatic ecosystems

    The chemical‐specific risk‐based paradigm that informs monitoring and assessment of environmental contaminants does not apply well to the many thousands of new chemicals that are being introduced into ambient receiving waters. We propose a tiered framework that incorporates bioanalytical screening tools and diagnostic non‐targeted chemical analysis to more effectively monitor for contaminants ...

  • Greywater reuse through a bioretention system prototype in the arid region

    The concept of a greywater-fed bioretention system in arid regions was investigated in this study. Bioretention systems are conventionally used as a source control mechanism for urban runoff. Nevertheless, in arid regions, where rain and urban runoff are not an abundant water resource, their application is limited. Greywater (residential wastewater without toilet and kitchen sources) is ...
