- The emission and production of chlorinated aromatics from metallurgical industries, e g scrap-metal re-melting, show substantial variations due to a number of process factors. The data evaluated indicates clearly that the production of chlorinated aromatics is combustion controlled.

Chlorinated aromatics from the combustion of hazardous waste
- 1985
-
Ingår i: Chemosphere. - : Elsevier BV. - 0045-6535 .- 1879-1298. ; 14:2, s. 215-221
-
Tidskriftsartikel (refereegranskat)abstract
- The production and emission of chlorinated aromatics from a hazardous waste incinerator were shown to be influenced by the operating conditions. The emissions of chlorinated benzenes, PCDD and PCDF show statistically significant correlations to the chlorine input. Different substance groups also correlate, and the results presented correspond well with a general formation mechanism of chlorophenols via chlorobenzenes as indicated by others.

Combustion test data from a Swedish hazardous waste incinerator

- Here we present results from our tests with PCB-incineration at the SAKAB hazardous waste incinerator in Norrtorp, Sweden. Combustion tests were made with PCB both as a fluid (Arochlor 1242) and as a contaminant of solid waste (Arochlor 1016 in capacitors). A general conclusion was that the incineration of considerable amounts of PCB did not effect the production of PCDD and PCDF in this combustion plant.

Tidskriftsartikel (refereegranskat)abstract
- A large quantity of emission data for PCDD and PCDF have been reported to date. Less information is available concerning the controlling parameters for the production of chlorinated aromatics from waste combustion. Here we report results and conclusions from investigations carried out in the Scandinavian countries to date.

- The emission and chlorination pattern of polychlorinated dioxins and dibenzofurans from waste combustion shows a close covariation with that of chlorinated benzenes and phenols. This covariation can be utilized to predict the emission levels of specific isomers as well as the pattern of congeners.

- The production of polychlorinated dioxins and dibenzofurans shows a strong correlation with the production of hexachlorobenzene. Hexachlorobenzene can be used as an indicator for the production of chlorinated aromatics.

- Relations between different chlorinated aromatics have been evaluated in 66 samples from various industrial activities. For municipal waste combustion partial least squares modelling with latent variables (PLS) can explain 86 % of the variance in PCDD/PCDF from the isomerspecific analytical data for chlorinated benzenes and phenols.

High metal reactivity and environmental risks at a site contaminated by glass waste
- 2016
-
Ingår i: Chemosphere. - : Elsevier BV. - 0045-6535 .- 1879-1298. ; 154, s. 434-443

Tidskriftsartikel (refereegranskat)abstract
- This study addresses the reactivity and risks of metals (Ba, Cd, Co, Cr, Cu, Ni, Pb, Zn, As and Sb) at a Swedish site with large glass waste deposits. Old glassworks sites typically have high total metal concentrations, but as the metals are mainly bound within the glass waste and considered relatively inert, environmental investigations at these kinds of sites are limited. In this study, soil and landfill samples were subjected to a sequential chemical extraction procedure. Data from batch leaching tests and groundwater upstream and downstream of the waste deposits were also interpreted. The sequential extraction revealed that metals in <2 mm soil/waste samples were largely associated with geochemically active fractions, indicating that metals are released from pristine glass and subsequently largely retained in the surrounding soil and/or on secondary mineral coatings on fine glass particles. From the approximately 12,000 m(3) of coarse glass waste at the site, almost 4000 kg of Pb is estimated to have been lost through corrosion, which, however, corresponds to only a small portion of the total amount of Pb in the waste. Metal sorption within the waste deposits or in underlying soil layers is supported by fairly low metal concentrations in groundwater. However, elevated concentrations in downstream groundwater and in leachates of batch leaching tests were observed for several metals, indicating on-going leaching. Taken together, the high metal concentrations in geochemically active forms and the high amounts of as yet uncorroded metal-rich glass, indicate considerable risks to human health and the environment.
