Capacity estimation and preliminary strategy for reducing the release of dioxins in China
As a party of the Stockholm Convention on Persistent Organic Pollutants, China must submit its national implementation plan (NIP) for this convention. The strategy and action plan for reducing the release of dioxins in China are the most important components of the NIP. Three problems are key points for developing such strategy and action plan—what are the key sources for applying the best ...

Levels of dioxins in soil and corn tissues after 30 years of biosolids application
Detectable levels of dioxins have been reported in biosolids, but very little information is available on the effect of long-term application of biosolids on dioxins accumulation in soil and uptake by plants. We analyzed dioxins in soil and corn tissue samples from field plots after 30 continuous applications of biosolids at 0 (Control), 16.8, and 67.2 Mg biosolids ha−1 yr−1 resulting ...

Prevention of dioxins de novo formation by ethanolamines
Abstract Two inhibitors, triethanolamine (TEA) and monoethanolamine (MEA), were tested for their ability to prevent the de novo formation of polychlorinated dibenzo- p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) on sinter plant fly ash. The amounts of both PCDDs and PCDFs, formed by thermal treatment of the fly ash, decreased when inhibitors were added. Up to 90% reduction of the ...

Dioxin sampling – A long term view
1) Introduction The expansion of the number of processes requiring measurement of emitted dioxins and the release of a new CEN Standard - EN 1948 - will significantly alter the market for instrumentation. Within the EU, individual member states will implement their own strategies for process approval based on dioxin sampling. However, typically processes are assessed quarterly, biannually or ...

Determination of Dioxins and Furans in Soil using the SpeedExtractor E-916
Polychlorinated dibenzo dioxins (PCDDs) and polychlorinated dibenzo furans (PCDFs) are persistent organic pollutants (POPs) banned by the Stockholm Convention and they are therefore monitored worldwide. PCDDs and PCDFs were extracted from a soil sample with the SpeedExtractor E-916 and an ASE 200 system (Dionex) according to the U.S. EPA Method 3545A. Dioxin and furan congeners were determined by ...

Sediment dioxin levels as the basis for risk assessment and human health criteria
Methods for assessing human health risks and establishing water quality criteria under the Clean Water Act are based on the assumption that fish accumulation of dioxin is correlated with the dissolved phase of the dioxin in the water column by a water-to-fish predictive factor called a bioconcentration factor. However, dioxin does not remain dissolved in the water column to any significant ...

Modelling wet and dry depositions of PCDD/F releases from industrial plants in Apulia, Southern Italy
The modelling system RAMS/CALMET/CALPUFF was used to simulate the atmospheric dispersion and deposition of dioxins emitted from industrial sources over the Province of Lecce (Italy). Comparison between data and predictions shows that the model reasonably simulates the deposition patterns. Dry deposition of PCDD/F extends mainly downwind of the sources following the prevailing wind direction. Wet ...

Gasmet GT90 Dioxin+ Is an Effective Solution for Dioxin Sampling
In this article we introduce you to the world of continuous dioxin monitoring and the Gasmet GT90 Dioxin+, which is an exceptionally robust dioxin sampling system. Did you know that it was designed to sample even the lowest dioxin and dioxin-like compound concentrations in harsh industrial environments, even in subfreezing conditions? In addition to dioxins, the system is capable of measuring ...

Importance of long-term sampling in dioxin monitoring
Dioxins and POPs are toxic, persistent, and nowadays ubiquitously present in our environment. Gasmet GT90 Dioxin+ is an exceptionally robust dioxin sampling system that was designed to sample even the lowest concentrations in harsh industrial environments and even subfreezing conditions. Dioxin is an umbrella name for polychlorinated dibenzo-para-dioxins and polychlorinated dibenzofurans. They ...

Chlorinated hydrocarbons - Case Study
Example: Pharmaceutical industry Similar tasks: Chemical industry The Pharmaceutical industry uses different processes to create chlorinated hydrocarbons. In a regenerative thermal oxidiser (RTO) the chlorinated organic contaminants are destroyed at high temperature. Chlorinated hydrocarbons - among others - are converted into hydrogen chloride which produces a hydrochloric acid solution after ...

Compilation of EU Dioxin Exposure and Health Data
Introduction There is considerable public, scientific and regulatory concern over the possible adverse health effects of chronic exposure to trace levels of persistent organic pollutants. The class of compounds made up of the polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzofurans (PCDF), often collectively known as dioxins, has received widespread attention and attracted a ...

The math behind long-term dioxin sampling
Can I let you in on a secret? Your current method of measuring dioxins is probably not giving you the whole picture about your dioxin emissions. A typical waste incineration plant will run for about 8000 hours per year. Many waste incineration plants are still using the old method of periodic sampling. With periodic sampling, dioxins are only measured for 6-8 hours at a time. You don’t need ...

Long-term Sampling of Dioxin and Carbon Dioxide
New regulations such as the European “Waste Incineration BAT Conclusions” (read more on that in this blog article) call for long-term sampling of "polychlorinated dibenzo-p-dioxins and -furans" (PCCD/F), but let's call it "dioxin" for simplicity. An isokinetic sample is taken from the duct and dioxin is trapped in an absorbing material. Special material has to be used and the sampler which ...

Trending Emissions Monitoring
Industrial emissions within the European Union are governed by the Industrial Emissions Directive, the IED. It is a framework directive largely relying on industry-specific reference documents on best available techniques, BREFs. The BREF for waste incinerators (WI) was revised during the 2010s and a new version became effective in December 2019. The expectations on industrial emissions control ...

Dioxins and Furans on the Equity-5
Dioxins and furans are byproducts of several different industrial processes, including incineration and paper bleaching. The extreme toxicity of several of these compounds has made their analysis in environmental samples increasingly important. In this application, the 60m x 0.25mm ID x 0.25µm Equity-5 was used to separate all 17 of the 2,3,7,8-substituted PCDDs and PCDFs listed in US EPA ...

Ecological risk assessment for mink and short‐tailed shrew exposed to PCBs, dioxins and furans in the Housatonic River area
A probabilistic risk assessment was conducted to characterize risks to a representative piscivorous mammal (mink, Mustela vison) and a representative carnivorous mammal (short‐tailed shrew, Blarina brevicauda) exposed to PCBs, dioxins and furans in the Housatonic River area downstream of the General Electric (GE) facility in Pittsfield, Massachusetts. Contaminant exposure was estimated using a ...

2006-2016: 10 years of continuous dioxins monitoring in Italy. Which assessment for which perspective? Polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzofurans (PCDF), more commonly named dioxins and furans are odorless, highly thermally stable, insoluble in water, highly liposoluble micropollutants present in traces in the environment, mainly produced during combustion with ...
