Fate of organic matter during moderate heat treatment of sludge: kinetics of biopolymer and hydrolytic activity release and impact on sludge reduction by anaerobic digestion
Temperature-phased anaerobic digestion with a 50–70 °C pre-treatment is widely proposed for sludge. Here, such a sludge pre-treatment (65 °C) was studied against the physical, enzymatic and biodegradation processes. The soluble and particulate fractions were analysed in terms of biochemical composition and hydrolytic enzymatic activities. Two kinetics of organic matter ...

Air Quality Monitoring
Why monitor air quality? Well, to monitor is to know. Everything else is just more or less qualified guesses. International, national and local air quality targets and limits are also tied to monitoring results. What is Air Quality? How is air quality characterised? It is quite common to find air quality indexes, where the ranges are divided in sections indicating “good”, ...

ANSI N13.1-2011 Stack Sampling Considerations
Background Nuclear facilities are required to follow industry standards for sampling stack effluents. Exposure of the general public to released radionuclides must be monitored as specified in US governmental regulations. The United States Environmental Protection Agency (USEPA) and the United States Nuclear Regulatory Commission (USNRC) have the authority over the monitoring of these releases. ...

Availability of different phosphorus forms in agricultural soil to
Microcystis aeruginosa We investigated the availability of different forms of particulate soil phosphorus (P) to Microcystis aeruginosa by sequential extraction and bioassay. We cultured M. aeruginosa in media containing, as the sole source of P, soils sequentially extracted with 1 M NH4Cl, 0.11 M bicarbonate dithionite, 1 M NaOH, and 0.5 M HCl. Analyses of chlorophyll-a, particulate organic carbon, and particulate ...

Characterisation for some emission sources in CMB calculation for Mae Moh area, Thailand
Particulate samples of agricultural waste burning, straw burning, forest leaf burning, heavy duty truck emission, paved road dust, soil, agricultural soil, coal, electrostatic precipitator ash, and emission from stack power plant were collected from the Mae Moh area. Chemical compositions of sampling filters were analysed to determine the particulate matter source profiles. The analysis included ...

Air pollution in Europe 1990-2004
Overall picture This report analyses and presents changes in air pollutant emissions and their possible health or ecosystem impacts in Europe covering the period 1990–2004. Emissions of all air pollutants fell substantially during the period 1990–2004 in the 32 EEA member countries (EEA-32), resulting in improved air quality over the region. However, ambient concentrations of particulate matter ...

Inside the Particulate Monitor – Filter Samplers
Some time ago, OPSIS published descriptions on how some well-established types of gas analysers work, namely those based on spectrometers, interferometers, and tuneable diode lasers. They all utilize absorption of light to determine the concentrations of gaseous pollutants such as nitrogen oxides (NOX), sulfur dioxide (SO2), hydrogen chloride (HCl), ammonia (NH3), and many more. The same ...

Top 5 Differences Between Micro Pulse LiDAR and Ceilometer Technology
If you are evaluating backscatter LiDAR sensors for measuring aerosols, cloud vertical structure, and planetary boundary layer (PBL) heights, what factors should you consider in your comparison? It really comes down to a choice between the traditional analog technology used in ceilometers ad the more recent advanced technology found in Micro Pulse LiDAR (MPL) sensors. To select the best tool for ...

Status of black carbon monitoring in ambient air in Europe
Black carbon (BC) is increasingly discussed in science and environmental policy areas as an example of an air pollutant that affects both human health and contributes to climate change (e.g. WHO, 2012; UNEP/WMO, 2011; Bond et al., 2013; IPCC, 2013). In order to be able to make comparable measurements of BC in ambient air and to relate BC monitoring to health impacts and climate change it is ...
