  • Toxicological and Environmental Safety Data - Case Study

    Introduction AGRAGEL is a cross-linked copolymer of acrylic acid and acrylamide partially neutralized as potassium/ ammonium salt. The polymer is in its dry form a granulate and forms a gel-like material upon addition of water or aqueous solutions. Due to the cross-linking it is insoluble in water. Uptake of water is facilitated mainly by the negative carboxylic groups of the polymer and ...

  • A new approach for the laboratory culture of the fathead minnow, Pimephales promelas

    Fathead minnows are routinely cultured for use in aquatic toxicology studies. A new mass culture system described in the present study consisted of 6 stainless steel tanks, each containing 68 fish and 20 spawning substrates. Spawning results are compared with a previous system of 22 individual glass aquaria, which contained 16 fish and 4 spawning substrates per tank. During a 19‐mo period, the ...

  • Application of an optimized system for the well-defined exposure of human lung cells to trichloramine and indoor pool air

    In this study an in vitro exposure test to investigate toxicological effects of the volatile disinfection by-product trichloramine and of real indoor pool air was established. For this purpose a set-up to generate a well-defined, clean gas stream of trichloramine was combined with biotests. Human alveolar epithelial lung cells of the cell line A-549 were exposed in a CULTEX® device with ...

  • Elimination of pharmaceuticals from the wastewater of a pharmaceutical plant

    Roche AG had commissioned the company EnviroChemie to develop a new procedure for a new production facility in Mexico, which prevents the undesired release of ecotoxicologi-cally contaminating drugs into the environment and eliminates pharmaceuticals in the wastewater directly at the point of origin, even before the\ enter the general sewage treatment plant. In the first step, the three different ...

  • Fugacity and activity analysis of the bioaccumulation and environmental risks of decamethylcyclopentasiloxane (D5)

    As part of an initiative to evaluate commercial chemicals for their effects on human and environmental health, Canada recently evaluated decamethylcyclopentasiloxane (D5; CAS no. 541‐02‐06), a high–volume production chemical used in many personal care products. The evaluation illustrated the challenges encountered in environmental risk assessments and the need for the development of better ...

  • Toxicity Testing Moves Ahead

    Lynn L. Bergeson, “toxicity testing moves ahead,” chemical processing, September 2010. The Tox21 Partnership aims for far faster and less expensive screening. Who would have thought that an automated laboratory working around the clock could screen chemical substances for interactions with biological targets at speeds mere mortals could hardly consider — let alone match? Well, ...

  • A risk assessment example for soil invertebrates using spatially explicit agent‐based models (ABMs)

    Current risk assessment methods for measuring the toxicity of plant protection products (PPPs) on soil invertebrates use standardised laboratory conditions to determine acute effects on mortality and sublethal effects on reproduction. If an unacceptable risk is identified at the lower tier, population‐level effects are assessed using semi‐field and field trials at a higher tier because ...

  • Fast and reliable analysis of wastewater and sludges with a scanning array ICP emission spectrometer

    Wastewater and sludge analyses generally require the determination of many elements and are economically performed using ICP-OES, due to the speed and robustness of this technique. Several ICP-OES methods are available for this determination including EPA method 200.7 (1). In the USA, DIN 38 406 E22 (2) in Germany, or ISO 11885 (3) on a global scale. For this type of application, the ...

  • Endocrine Disruptors

    Overview: Substances that mimic, influence, or interfere with the body's endocrine system at certain doses, and produce potentially adverse developmental, reproductive, neurological, and/or immune effects in both humans and wildlife, are called endocrine disruptors. These substances can be naturally-occurring or man-made. Endocrine issues have long been the subject of intense ...
