National Cadmium Management Committee Finishes
The National Cadmium Management Committee (NCMC) ceased to operate as of December 2006 having achieved essentially all of its initial aims and having achieved others that arose during its five year term. Despite the Committee no longer operating this web-site will be maintained with periodic updates until July 2011. Read the NCMC Workshop outcomes.
Contaminants in Fertiliser Project
The Fertilizer Working Group (FWG), which reports to the Primary Industries Standing Committee (PISC), in collaboration with the Industrial Residues Working Group (IRWG) which reports to Environment Protection and Heritage Council (EPH&C) have established a project to examine the issue of Contaminants in Fertilizers. This project aims to develop:
- A list of chemicals which should not be present in fertilizers
- A list of chemicals which can be present in fertilizers providing they are below acceptable concentrations
- The acceptable concentrations of chemicals permitted in fertilizers.
This project is being undertaken in three separate stages. The first stage – a scoping study – has been undertaken by the Centre for Environmental Contaminant Research in CSIRO. A copy of this Scoping Study is available for download (PDF, 733 kB).
Stage II – Is a preliminary hazard screening and assessment of environmental and agricultural impacts and benefits of applying the identified potential contaminants and sources of contaminants to agricultural land.
Stage III – This will be a more detailed assessment using a combination of existing criteria and, where necessary, risk assessment from first principles to determine recommended maximum concentrations and/or loadings of substances identified as presenting a high potential risk.
Tenders for Stage II will close 31 January, 2007.
Laboratories Proficient in the Analysis of Cd in Plant Samples
During 2004 ASPAC decided to change the structure of the ILPPP. In the new program laboratories can be declared proficient in analyzing cadmium in both soil and plant samples. The soil and plant programs each consist of three sets of samples to be analysed annually with four samples per set. The results of the ILPP will shortly be made available by ASPAC. As soon as this is done a hyperlink from the NCMC website to the appropriate section of the ASPAC website will be made.
What should you do in the meantime?
You should use the list of proficient laboratories set out below to make your selection and ask them laboratory whether they have currently deemed to be proficient in the analysis of Cd in plant tissue by ASPAC. If they are not then there results may not be reliable.
and Contact Details For ASPAC Certified
Plant Cadmium Proficient Laboratories,
The National Cadmium Management Committee (NCMC) is often asked
to recommend a laboratory that can proficiently determine cadmium
(Cd) concentrations in plants. In response, the NCMC wrote to
the 31 laboratories that participated in the annual Inter-laboratory
Plant Proficiency Program conducted in 2002 by the Australasian
Soil and Plant Analysis Council Inc (ASPAC; Johnstone et al 2002).
This program assessed laboratory performance for a range of tests,
including plant Cd. The laboratories were asked that, if they
had elected to include Cd in their test suite, and if they had
gained proficiency for that test, would they agree to their contact
details being placed on the NCMC website.
The listing of Cd proficient laboratories (2002) is provided
in the table below. These laboratories were assessed by ASPAC
to be proficient in the measurement of total cadmium in a selection
of oven-dry plant materials. The proficiency certification remains
until superseded by ASPAC’s next Inter-laboratory Plant
The NCMC acknowledges that not all laboratories that may be competent
in the analysis of total Cd in plant material participated in
the ASPAC Inter-laboratory Proficiency Programs. Potential clients
and users of laboratories may wish to also check if the laboratory
is NATA accredited for total Cd analysis in plant samples.
Finally, ASPAC now has on its public web site (www.aspac-australasia.com)
an informative article entitled “How Can I Be Sure That
The Lab Is Giving Me The Right Results?” While not targeted
specifically at Cd analysis, the advice presented in this article
warrants serious consideration.
