  • Clearing the Air: Palm Oil, Peat Destruction, and Air Pollution

    Landscape fires in Southeast Asia take a heavy toll on human health and the economy. Increasing demand for deforestation-free palm oil can help reduce the damage. Each year in Southeast Asia, landscape fires burn out of control, spreading a debilitating haze across the region. This air pollution causes severe damage to human health, claiming over a ...

  • Tracking pollution at a personal level

    Two big stories from 2014 were the amount of air pollution in cities, especially in China, and the rise of “wearables” and other personal technologies people use to track things about themselves, often having to do with health and fitness measurements, such as steps taken, hours slept, heart rate and more. Now, the ...

  • Measurement of TOC in High-Salt Sample

    The quantity of organic matter in seawater is important in the research and monitoring of marine pollution as an indicator of organic pollution. The salt content in seawater is typically about 3.5 %, but using the Shimadzu total organic carbon analyzer, it is possible to measure the TOC directly without dilution or other pretreatment procedures. Here, we introduce an example of measurement of ...

  • The potential of lipopolysaccharide as a real-time biomarker of bacterial contamination in marine bathing water

    The use of total lipopolysaccharide (LPS) as a rapid biomarker for bacterial pollution was investigated at a bathing and surfing beach during the UK bathing season. The levels of faecal indicator bacteria Escherichia coli (E. coli), the Gram-positive enterococci, and organisms commonly associated with faecal material, such as total coliforms and Bacteroides, ...

  • Using UV Fluorescence technology to monitor for organic pollutants in Flood Water

    For many years the water industry has relied on traditional sampling techniques to monitor water quality in a wide range of environments.  Traditional tests such as BOD, PH, Dissolved Oxygen and Ammonia have formed the bedrock of monitoring parameters.  There is however other ways to establish water quality and UV fluorescence offers an up to date solution for the investigation of ...

  • Water quality assessment of a polluted urban river

    Urban rivers in Latin America are heavily impacted by human activities that affect their functions and services. This paper shows the results of a water quality assessment for the Reconquista River, the second most polluted urban river in Argentina. They allowed the identification of the main processes of transport of pollutants and the prioritisation of different areas of the basin for ...

  • Plasma concentrations of organohalogenated pollutants in predatory bird nestlings: Associations to growth rate and dietary tracers

    The extent to which persistent organic pollutants (POPs) with different physicochemical properties originated from the food (dietary input) was assessed in raptor nestlings. Lipophilic polychlorinated biphenyl (PCB) 153, 1‐dichloro‐2,2‐bis (p‐chlorophenyl) ethylene (p,p'‐DDE) and hexachlorobenzene (HCB), and protein‐bound perfluorooctane sulfonate (PFOS), were measured repeatedly in blood ...

  • Distribution of sterols and the sources of pollution in surface sediments of Ulungur lake, Xinjiang

    Domestic sewage discharged into lakes brings great pressure to the ecological environment. This study selected sediment from an inland lake as a research object to evaluate pollution of the environment. Eight sterols were used to evaluate the content of pollutants, while the ratios of sterols were used as the index to analyze the sources of pollution. The correlations were analyzed between ...

  • Forty‐seven days of decay does not change persistent organic pollutant levels in loggerhead sea turtle eggs

    Reptile and bird eggs are priority samples for specimen banking programs that assess spatial and temporal trends of environmental contaminants. From endangered species, such as sea turtles, nonlethal sampling is required (e.g., unhatched eggs collected postemergence). Previous contaminant monitoring studies have used unhatched sea turtle eggs, but no study has tested whether their ...

  • Soil sorption characteristics of imidacloprid in different Croatian regions

    In Croatia, imidacloprid is increasingly used in olive growing areas against the olive fruit fly. Experiments were conducted to examine the relationship between soil properties, imidacloprid concentration and soil sorption capacity. The linear and the Freundlich model adequately described the imidacloprid sorption. Better sorption was observed at lower imidacloprid concentrations and in soils ...

  • Calibration and use of the polar organic chemical integrative sampler—a critical review

    The implementation of strict environmental quality standards for polar organic priority pollutants poses a challenge for monitoring programs. The polar organic chemical integrative sampler (POCIS) may help to address the challenge of measuring low and fluctuating trace concentrations of such organic contaminants, offering significant advantages over traditional sampling. In the present review, ...

  • Aptamer-based and DNAzyme-based biosensors for environmental monitoring

    Aptamers and DNAzymes are small single-stranded nucleic acids that fold into a well-defined three-dimensional structure with high specificity to various ligands, such as low-molecular-weight organic or inorganic substrates or macromolecules. Their specificity is comparable with and in certain cases even higher than those of antibodies, and they can be applied for specific detection of various ...

  • Priority organic pollutants in the urban water cycle (Toulouse, France)

    Application of the European Water Framework Directive requires Member States to have better understanding of the quality of surface waters in order to improve knowledge of priority pollutants. Xenobiotics in urban receiving waters are an emerging concern. This study proposes a screening campaign of nine molecular species of xenobiotics in a separated sewer system. Five sites were investigated ...
