  • Biological monitoring system, iTOXcontrol, continues in Scarlino - Case Study

    The recorded death of fish in the river that flows out of the industrial zone of Scarlino has created the need of the installation of a biological alarm system. The decision was made to work with an automatic system, iTOXcontrol created by microLAN-The Netherlands represented in Italy by Ecotox Lds, which uses marine bacteria. The system compares the values of the light emission from these ...

  • Human pharmaceuticals in the marine environment: Focus on exposure and biological effects in animal species

    Marine waters have been poorly investigated for the occurrence of pharmaceutical contamination. Recent data confirm that pharmaceuticals widely occur in marine and coastal environments; therefore assessment of potential risk to marine species needs further efforts. The present paper represents the first extensive review of pharmaceutical contamination in marine environments addressing the ...

  • Precellys application focus cancer research oncology - case study

    Cancer research laboratories working with tumor tissues derived from animal models (1,2) or xenografts (3) face difficulties in homogenizing these tough samples using traditional methods (4). The Precellys homogenizers provides high speed sample disruption based on bead- beating technology for the extraction of DNA, RNA, protein, enzymes and metabolites within minutes. It ensures high ...

  • Precellys application focus forensic - case study

    Forensic laboratories working with hard samples such as hair [1, 2J, bone [3], teeth, skin, etc. experience difficulties with DNA extraction due to the high energy needed to grind these tissues. Moreover, biological evidence is available in small quantities and the current techniques used do not provide high quality results. The Precellys homogenizers provides high speed sample disruption based ...

  • What is HACCP?

    Hazard Analysis and Critical Control Points (HACCP, for short) is defined by the US Food and Drug Administration as a “management system in which food safety is addressed through the analysis and control of biological, chemical and physical hazards from raw material production, procurement and handling, to ...

  • Humification of effluent organic matters through a surface-flow constructed wetland

    Dominant fractions of wastewater effluent organic matter (EfOM) were changed from polysaccharides (PS) to polyhydroxyaromatics (PHA), throughout the constructed treatment wetland connected to a wastewater treatment plant, as measured using pyrolysis gas chromatography-mass spectrometry (Py-GC/MS). The changes in the fractions were also identified, with respect to molecular weight (MW) ...

  • The practicalities and pitfalls of establishing a policy‐relevant and cost‐effective soil biological monitoring scheme

    A large number of biological indicators have been proposed over the years for assessing soil quality. While many of those have been applied in monitoring schemes across Europe, no consensus exists on the extent to which these indicators might perform best and how monitoring schemes can be further optimised in terms of scientific and political relevance. Over the past decade developments in ...

  • TopAir`s PCR Station

    The PCR station is a cleanroom area with specialized equipment for the biomedical field. The PCR station handles Polymerase Chain Reaction (PCR), a molecular technique for producing large quantities DNA from using an enzymatic reaction without requiring a living organism. Because of the high sensitivity of the procedure, careful attention to the work process in the PCR station is required. The ...

  • An interlaboratory comparison study for the determination of dialkyl phthalate esters in environmental and biological samples

    A series of interlaboratory comparison exercises were conducted to assess the accuracy of dialkyl phthalate ester (DPE) concentration measurements in environmental and biological samples. Five laboratories participated in analyses to determine DPE concentrations in standard test solutions; marine sediments; three certified reference materials (CRMs), including CARP‐2 (fish muscle) and BCR‐07 ...

  • Freeze–thaw treatment of RBC sludge from a remote mining exploration facility in subarctic Canada

    Freeze–thaw conditioning of RBC (Rotating Biological Contactor) sludge was tested using a pilot-scale freezing bed placed in a mobile freezer operated at −10°C. Sludge samples from a remote mining exploration facility were flown in every 2 weeks, and added to the freezing bed in 8 layers of 10 cm thick. Approximately 4 months after the first layer of sludge was added, the pilot unit was removed ...

  • Influent concentrations and removal performances of metals through municipal wastewater treatment processes

    This extensive study aimed at quantifying the concentrations and removal efficiency of 23 metals and metalloids in domestic wastewater passing through full-scale plants. Nine facilities were equipped with secondary biological treatment and three facilities were equipped with a tertiary treatment stage. The metals investigated were Li, B, Al, Ti, V, Cr, Fe, Ni, Co, Cu, Zn, As, Se, Rb, Mo, Ag, Cd, ...

  • How to Determine Aquatic Humic Substances

    Aquatic Humic Substances (AHS) result from the decomposition of plant and animal residues and are found in soil, sediment, and water. They are widespread in nature and are mostly comprised from naturally occurring dissolved organic matter in water. AHSs are an important component in water systems, particularly as they relate to the potential fate of chemicals in the aquatic environment. For ...


  • Diatoms for assessing the ecological condition of inland freshwater bodies

    The ecological responses of diatoms to pollution and nutrient enrichment, caused by domestic and municipal sewage, in the five fresh water ponds have been examined. It was observed that diatoms were completely absent in P3 and some species were also absent in P1 and P2. Similarly, diatom diversity was lower in P1 and P2 than in P4 and P5. However, diatom abundance was higher in P4. The Biological ...

  • Hard tissue samples as markers of occupational exposure in a phosphate fertiliser plant

    This paper describes the results of study on testing of hair and nails samples as possible markers of occupational exposure in a phosphate fertiliser plant. The key objectives were to verify if: (1) elements originating from fertiliser production may accumulate in hard tissue and hence allow preliminary occupational exposure risk assessment; (2) linear discriminant function analysis (LDA) may be ...

  • Enhancing Biological Nutrient Reduction in Advanced Individual Onsite Wastewater Treatment Systems

    ABSTRACTAdvanced onsite systems need to continue to improve wastewater treatment through nutrient reduction. Some advanced onsite systems have been shown to reduce nutrients significantly. However, with modifications, these systems can reduce total inorganic nitrogen (TIN) to an even greater degree, and nitrate to levels below federal drinkingwater standards. INTRODUCTIONNitrogen compounds in ...

  • Effect of fibre on shear strength of residue from mechanical–biological pretreatment of waste

    Fibres in the waste have a strong influence on shear strength. This is because even though the waste is characterised as a coarse material with a non-cohesive granular behaviour, it may nevertheless display high values of pseudocohesion due to the effect of the tensile strength of the fibre inclusions. Samples of pretreated residue with different particle sizes were prepared to study this effect. ...
