Limit Of Quantitations (LOQs)


Monitoring of polybrominated diphenyl ethers residues

Result and discussion

The PBDEs concentration of each sediment samples was not detected although

the sampling station was located surrounding the industrial area.

For the remote areas the PBDEs concentration were also not detected with LOQs.

Historical PBDE in Thailand, the country has never produce or import PBDE. After Thailand agree to banned the PBDE follow the Stockholm convention, Ministry of Natural Resources and Environment request to our research center (ERTC) start to monitor sediments from possible point source and remote area to supported data for Environmental Pollution Department , which is secretarial of the Stockholm convention Thailand. The data from UNU project used for supporting the convention.

Thailand already set up The National Implementation Plan (NIP) for new POPs.


Monitoring of polybrominated diphenyl ethers residues

Conclusion

The United Nations University project produce fruitful technique and new data. And it can support the our environmental policy of Thailand, especially new POPs. Therefore, we hope that the UNU and Shimadzu can continue technical support for other new POPs.

Acknowledgement

I am very appreciate for all supports from Shimadzu for developing method of the PBDEs analysis in sediment and financial support the project from UNU.

Lastly, I thanks for our staffs at ERTC to support UNU project, do analyse the sample and sampling.
