The Chemtest team, presented and exhibited at Pro Geo 2017 (South-West Regional Group) in Exeter on Wednesday 4th October 2017 http://bit.ly/2xO4LBw
Chemtest were delighted to present alongside John Grimes Partnership Ltd on ‘Uncertainties in Arsenic Risk Assessment in South West England’. The presentation also covered the following Bioaccessibility tests:-
-Physiologically Based Extraction Test (PBET) – Modified Ruby method
-BARGE Unified Bioaccessibility Method (UBM)
The differences between the tests above were highlighted in the talk.
‘The physiologically based extraction test (PBET) is an in vitro test system for predicting the bioavailability of metals from a solid matrix and incorporates gastrointestinal tract parameters representative of a human (including stomach and small intestinal pH and chemistry, soil-to-solution ratio, stomach mixing, and stomach emptying rates).’
The Contamination Expo Series is Europe’s largest exhibition and conference designed to showcase the latest innovations that further the protection of the environment and management of contaminated land, water, and air. Follow this link to find out more
This event will be hosting an impressive schedule of unmissable seminars, covering a wide range of pertinent topics such as Landfills, Chlorinated Solvents, Asbestos, Hazardous Substances & Environmental Forensics.
Chemtest’s Dr. Ken Scally and Amy Parekh-Pross, will be presenting on ‘Advances in Air Testing & Environmental Forensics for Contaminated Sites’
Dr. Ken Scally our Director of Environmental Forensics comments:
“To achieve a successful environmental forensics investigation, it will encompass an understanding of a variety of disciplines and the wisdom to select the most appropriate forensic tool(s) which are best suited for a particular set of facts”
Chemtest have been awarded UKAS accreditation for LOI Testing of Trommel Fines in accordance with HMRC Landfill Tax Notice LFT 1.
What are Fines?
For Landfill Tax purposes, fines are particles produced by a waste treatment process that involves an element of mechanical treatment. For example, trommelling, screening or soil washing are all mechanical processes
In order to qualify for the lower rate of landfill tax, the fines must meet the specified Loss on Ignition (LOI) threshold of 10%.
LOI is a test for determining the organic content of material. The difference in the mass of the material being tested before and after the ignition process is used to calculate the LOI result. The LOI result will inform whether the waste is liable to the lower rate of Landfill Tax but is not the only determining factor. The fines must meet all the requirements and conditions set out in the HMRC guidance in order to be liable to the lower rate.
The sample submitted for testing must be representative of the whole quantity of waste material for disposal. It is specified that 6 sub-samples are selected at random and mixed to form a composite sample of 1 kg.
How is the LOI Testing of Waste Fines carried out?
The sample is air dried and coned and quartered by the laboratory to produce a 200 gram sub-sample This sample is sieved to remove content classified as >20mm group 1 and 2 material (eg stones). The sub-sample is then ground to a particle size of <2mm and a 20g sample is taken for testing. Loss on ignition is determined between 180oC and 440oC, taking into account the mass of removed >20mm group 1 and 2 material. It is mandatory for laboratories use this methodology prescribed in HMRC Landfill Tax Notice LFT1.
Chemtest are now UKAS accredited for this procedure.
