Characteristics of PM2.5 in rural areas of southern Jiangsu Province, China
To understand pollution level and possible sources ofatmospheric fine particulates in rural areas of southern Jiangsu Province of China, samples of PM2.5 were collected and analyzed in Xueyan Town and Taihu Lake Station over three seasons from July 2002 to January 2003. The mass concentrations of PM2.5 and 14 principal component elements were obtained. The results showed that pollution of PM2.5 ...

Continuous monitoring of polycyclic aromatic hydrocarbons using automatic thermal desorpition-gas chromatography
Polycyclic Aromatic Hydrocarbons (PAHs) are a group of over 100 different chemicals that are known to be formed typically during incomplete combustion of organic matter at high temperature. Their major sources in the atmosphere include industrial processes, vehicle exhausts, waste incinerations, and domestic heating emissions. Due to their carcinogenic/mutagenic effects. 16 PAHs are currently ...

Flow measurement with PicoFlow - Case Study
Application A waste incineration plant produces exhaust gases during the incineration process. These gases need to be cleaned. Therefore hearth furnace coke is used continuously and, if needed, lime hydrate. Both materials are stored in silos. Via a rotary valve the two materials are blown from the storage places into a conveying air fl ow and thereby reach the exhaust gas stream which they ...

Want to avoid holiday stress? Take care of your mercury monitoring now for a happy Christmas
Christmas can be a stressful time. You have to buy gifts, decorate, bake sweets, attend parties, and avoid talking to that one relative that always drives you crazy. But if you think you’re stressed now, wait until 2023. That’s when the Best Available Techniques Reference documents on waste incineration (WI BREF) will require stricter mercury monitoring on larger waste incinerators in ...

Measurement method for determination of the ratio of biogenic and fossil-derived CO2 in stack gas
ABSTRACT In this paper, we present a measurement method for sampling and analysis of the ratio of biogenic and fossil-derived CO2 in stack gases from the combustion of mixed fossil and biogenic fuels. The measurement method was developed as a part of a project performed for Energinet.dk and the association of waste incineration and treatment plants in Denmark. The methodology for sampling and ...

Ecological risk assessment of parent and halogenated polycyclic aromatic hydrocarbons in surface sediments from an urban river in south China
In the present study, 16 priority polycyclic aromatic hydrocarbons (Σ16PAHs), including seven carcinogenic PAHs (Σ7PAHs) designated by the U.S. Environmental Protection Agency, in surface sediment from an urban river (Shenzhen, south China) were measured. The concentrations of Σ16PAHs and Σ7PAHs ranged from 27.92 to 7409 ng/g and 0.53 to 2326 ng/g, respectively. Source appointments indicated that ...

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 ...

New boiler MACT and affiliated rules proposed
EPA proposed three related rules (with final rules expected by December 16, 2010), intended to reduce the emission of hazardous air pollutants (HAPs) from industrial, commercial, and institutional boilers and process heaters as well as commercial and industrial solid waste incinerators. Simultaneously, it also proposed a definition of solid waste that could potentially affect some units currently ...

Long-term sampling - A method for continuous emission monitoring of dioxins/furans and mercury
Introduction The continuous emission monitoring of the different compounds which are emitted by industrial facilities is an important topic to approve the compliance to different regulations like WID. However, there are several compounds which cannot be measured in real time. Specific dioxins/furans (PCCD/PCDF) and other POPs (Persistent Organic Pollutants) cannot be measured by online monitors. ...

Continuous measurement of mercury emissions in combustion plants (Overview and new measuring method)
Introduction Continuous measuring devices have been used for continuous recording of Hg emissions in waste incineration plants since the early Nineties. Operators of combustion plants must maintain a 24-hour measured value of 30 μg/m³ mercury and a half-hourly average value of 50 μg/m³ in accordance with the 13th and 17th BImschV. In order to meet these requirements, measuring ...

Impact of CO2 Emission Trading Schemes on Residual Waste Management
ABSTRACT The EU-Emission trading scheme (ETS) in its current design hardly affects residual waste management directly: methane from landfill-sites is not included although it is one of the “Green-House-Gases” (GHG) of the Kyoto Protocol, CO2-emissions from waste incineration plants are generally exempted from the regulation of the directive and emissions from combustion of landfill-site gas can ...

How to Monitor Mercury Emissions
In recent years, mercury levels in the environment and in the food chain have risen substantially mainly due to human activities. As a long-range pollutant it can affect areas located thousands of kilometers away from its original source of emission. It’s no wonder then that the regulatory pressure to monitor mercury emissions grows stronger. Before diving into the analysis techniques and ...

Regulating Mercury Emissions
Historically, mercury (Hg) has found its use in many products such as thermometers, batteries, and fluorescent lamps. However, mercury is extremely toxic, and it has in modern days been banned from use in most applications.By example, the Minamata Convention on Mercury from 2013 has been designed to prevent releases of mercury and mercury compounds in order to protect human health and the ...

CEMS: An Overview
We've written an overview to where CEMS are required, types of site that require CEMS and future requirements. Continuous Emissions Monitoring Systems are used to continuously collect, record and report data from industrial process operators that produce emissions to air. CEMS are used as a means to comply with stringent emission limits as regulated by the Environment Agency (EA). Under the ...

VOC monitoring on stationary sources: from environmental policies to technical solutions
In the past, the primary origin of local air pollution has been emissions from stationary sources. These sites include power generating plants, oil refineries, chemical plants, steel factories, cement and glass manufacturing companies, space heating, and many other industries. Pollutants are emitted into the air from these plants through fossil fuel combustion, chemical processes, and the ...
