Subject: Official Information request - Fluorocitrate and nitrogen
fixation tests and replicated research

 

Dear Landcare Research

 

Under the official Information Act I would like to ask the following
questions:

 

1. Is there a test for any type of fluorocitrate available in New Zealand
(this is a metabolite of 1080)? How long has it been available?

2. Have you ever tested for fluorocitrate in water, in alga, or in animal
tissue? What else have you tested for fluorocitrate?

3. Have fluorocitrate tests ever been done internationally on our water,
alga, animal tissues, etc?

4. If the fluorocitrate test(s) do not exist in New Zealand, who made the
decision not to have the tests available or to test for fluorocitrate?

5. Do you believe there is a need for the fluorocitrate test? Please
explain reasons for your answer.

6. If there is a test for fluorocitrate, what are we currently using this
test for?

7. Have you or any other research agency ever tested for fluorocitrate in
places like Lake Taupo in the water and in the alga?

8. Are you aware of the overseas research (see attached, Gallon et al)
that says that 1080 causes accumulated citrate, that it alters the lipid
composition of algal cells and that it also dramatically decreases the
ability of alga to fix nitrogen?

9. Has Landcare Research or any other research agency investigated this
phenomenon of 1080 causing accumulated citrate and affecting nitrogen
fixation in Lake Taupo or in any other water body in New Zealand? Note:
Lake Taupo now has a cap on nitrogen inputs, and councils around the
country are currently working on plan changes around reducing nitrogen
loss in their water catchments. MfE is involved in Lake Taupo nitrogen
management through the Lake Taupo Protection Project Joint Committee.

10. Are you aware that in the ERMA reassessment of 1080 in 2007 it stated
that 1080 is toxic to blue green algae and how significant is this? Is
this being investigated, or has this previously been investigated in
relation to the Rotorua lakes or Lake Taupo, or any other water body in
New Zealand in connection to eutrophication, and toxic algae?

11. Has this international research on fluorocitrate and its effect on
nitrogen fixation, ever been replicated in New Zealand? If not, why not,
when it was identified as an issue in the ERMA 1080 reassessment of 2007?

12. Has the issue of accumulated citrate and its impact on nitrogen
fixation been considered in the Predator Free 2050 decision-making
process? This programme has dramatically increased 1080 use in terms of
area and amount of bait used per hectare, and therefore it's possibly
causing increased nitrogen inputs to water.

13. Has your agency been involved in research on the issue of accumulated
citrate and its impact on nitrogen fixation as part of the Healthy Rivers
Plan Change through Waikato Regional Council, the NPS on Freshwater
Management or other water quality regulatory processes?

14. To your knowledge, could elevated fluorocitrate have implications in
other areas that should be explored through research? eg. soil quality,
regular meat testing for food safety.

 

I cannot attach the journal article by Gallon et al here. Please contact
me on [3][email address] for a copy.

 

Many thanks for your help.

Subject: Re: Official Information request - Fluorocitrate and nitrogen fixation tests and replicated research

Dear Landcare Research,

I would like to amend my request for information.

When I asked about fluorocitrate in water, I should have said fluorocitrate in aquatic organisms (for instance macroinvertebrates). Fluoroacetate can be detected in water but the metabolite fluorocitrate is only detected in cellular organisms - plants and air-breathing organisms from insects to elephants (please correct me if I'm wrong)

Also, can you please add a question to my request. I understand from reading the reassessment of 1080 in 2007, that we do not use the same water testing methodology for sodium fluoroacetate as a lot of other overseas countries. Can you please clarify this or confirm what the differences are in terms of testing water for 1080 (sodium fluoroacetate) in the US, Australia and in the UK, as opposed to how NZ tests and whether each country tests at parts per billion or trillion?

If there are differences in testing between countries (such as the UK, where the Gallon article about fluocitrate and nitrogen fixation was written), how might this affect our calculations and measurements of sodium fluoroacetate, and the metabolite fluorocitrate, and the overall risk assessment of 1080?

Can you please confirm what information you are waiting for from me? I saw that the status said you were waiting to hear from me. Did you want me to provide the Gallon article?

Yours sincerely,

Kathy White
