water toxicity sampling Applications

  • Waste water respirometry solutions for toxicity tracking

    If toxicity is identified in a mixed sewage entering a treatment works, the problem for the plant manager is to track and identify the source of the toxicity. This can be done by sampling the effluent stream at various points in its length. By working in a logical sequence back up the sewer network the number of samples can be minimised. This type of testing should be rigorously enforced for new product introduction by a waste producer, as well as sampling the effluents directly at source. The samples would be...

  • Waste water respirometry solutions for toxicity based consents

    Water companies, water authorities or publicly-owned treatment works (POTW) need to have some knowledge of the composition of the wastes they it receive. In addition to testing for ammonia and BOD or COD levels, treatment works can license industrial discharges on the basis of concentrations of some of the known toxic compounds. However, it is recognised that very many non-regulated toxic materials still enter the treatment works and reduce the efficiency of biodegradation, and may cause toxic shock. The way is...

  • Determination of Mercury in Water Samples by HG-AFS

    Mercury and its sompounds are highly toxic materials and can be transferred into the human body via water; the concentration of mercury in water generally is very low. With the superior sensitivity of Aurora`s Atomic Fluorescence Spectrometer, the LUMINA 3300, direct measurement of mercury in water sample is possible.

    Determination of zinc in water by fluorimetric method

    In accordance with WHO’s Guidelines for Drinking Water Quality there is no health-based guideline value of zinc in water concentration. Concentration of zinc in tap water can increase as a result of its dissolution from pipes. Also, elevated levels of zinc may be an indicator of increased concentrations of other toxic metals; thereby zinc in water analysis is an essential analytical task. Lumex Instruments provides sensitive and selective fluorimetric method for the measurement of mass concentration of zinc in...

    Determination of anionic surfactants in water by fluorimetric method

    Anionic surfactants (A-SAS) represent, by volume, the most important group of surfactants used in cleaning products and the oldest and the largest volume anionic surfactant is soap. In concentrations 0.1 ~ 1.0 mg/L A-SAS become toxic for aquatic environment. Lumex Instruments provides sensitive and selective fluorimetric method for the measurement of mass concentration of anionic surfactants in water samples using the FLUORAT-02 analyzer. The method became the Interstate standard for anionic surfactant in water...

  • Concerned about PAHs in Parking Lot Sealcoats?

    There is growing concern - and regulations in the works - over the use of sealcoating products due to their high PAH content.  In the United States and elsewhere, most sealcoats are made from coal tar which can be toxic to aquatic life and threaten public water supplies from rain and runoff. Sitelab can be used to quickly check the concentrations of polycyclic aromatic hydrocarbons and determine if it's made from coal tar or alternative petroleum based black top sealants.  Got samples?  We'll test them for...
