  • How to investigate mercury in the oceans?

    Mercury is a highly toxic metal that affects the environment and can endanger people's health, as a powerful neurotoxin. The combustion of coal, waste and fuel are releasing hundreds of tons of heavy metal into the atmosphere annually, and its sediment enters to soil and water. Mercury measurements are part of the EU project "Global Mercury Observation System". The long-term goal of this ...

    The Situation Various processes onboard ships, such as machinery wash-down, maintenance, and leakage generate oily wastewater. This contaminated water flow collects in the bilge of the ship. Marine diesel, lubricating oils, grease, as well as garbage may be present in bilge water. The bilge water is discharged overboard, with oil and grease concentrations in the discharged water limited ...

  • Monitoring Metal Contamination in Water

    Metal contamination in drinking and source water has proven to have economic and health impacts on the human race. Regulatory agencies understand the importance of remediating metal contamination in our water supply to ensure safe consumption of drinking water. In order to properly remediate our water supplies, one must first determine cause of contamination and the source of the problem. ...

  • Monitoring Phenol in Water

    The Situation A plant located in the eastern United States manufactures phenolic resin for applications in plastics molding. This plant uses well water for cooling its reaction process and then discharges the water into a local creek. A leak in the reactor and associated cooling equipment would cause phenol and phenolic compounds to contaminate the cooling water. Such a leak could ...

  • Introduction to Fluorescence for Oil in Water Monitoring

    Fluorescence can be found in many applications throughout our day-to-day routines. Commercially, one of the most obvious uses is in fluorescent lighting. For this, fluorescence is used to emit light from a tube without the use of heat, unlike standard incandescent light bulbs that require a heated element. In this example, fluorescence also contributes to energy conservation efforts. At an ...

  • Water quality monitoring with hydrolab MS5

    Background The Škocjan caves are a unique natural phenomenon located in south western Slovenia and are preserved as the Škocjan Caves Park under UNESCO protection. One of the most famous network of underground caves in the world, they were formed by the flow of the Reka River as it bored tunnels through the region’s limestone geology. The river first disappears underground just outside the ...

  • Monitoring Nitrates in Drinking Water and Wastewater

    Nitrate is present in high levels in wastewater due in part to the high nitrates present in human sewage but also from some types of industrial effluent entering the municipal sewer system. Nitrate is also a very common contaminant in both surface water and ground water. Nitrate occurs naturally in source water as a result of decaying plants. However, there are other manmade sources of ...

  • Surfactant-assisted oil-in-water monitoring

    A variety of common surfactants have been used to reduce fouling and enhance the performance of fluorescence-based oil-in-water monitors. Among the most effective are the alcohol ethoxylates with HLB values close to 12. Examples are SurfonicTM L24-9 (Hunstman, USA, HLB 13) and TergitolTM 15-S-7 (HLB 12.1). These surfactants readily convert heterogeneous oil/water mixtures into homogeneous, ...
