The effect of bis-tributyltin oxide (TBTO) and copper on the growth of juvenile Sydney rock oysters Saccostrea commercialis (Iredale and Roughley) and Pacific oysters Crassostrea gigas Thunberg

Autor: Ramon Chvojka, John A. Nell

Publikováno v: Science of The Total Environment. 125:193-201

The growth of juvenile (spat) (1.25–2.62 mg dry wt) Pacific oysters C. gigas and Sydney rock oysters S. commercialis was reduced by only 5 ng bis-tributyltin oxide (TBTO) l−1 seawater. The reduction in growth of the Pacific oysters was more sever

Determination of Methyl Mercury in Fish by Flameless Atomic Absorption Spectroscopy and Comparison with an Acid Digestion Method for Total Mercury

Autor: Jurgen L Kacprzak, Ramon Chvojka

Publikováno v: Journal of AOAC INTERNATIONAL. 59:153-157

A method for the concurrent determination of methyl mercury and inorganic mercury by flameless atomic absorption spectroscopy (AAS) is described. Fifty-seven samples of juvenile black marlin fish were analyzed for inorganic and methyl mercury, and to

Mercury and selenium in axial white muscle of yellowtail kingfish from Sydney, Australia

Autor: Ramon Chvojka

Publikováno v: Marine Pollution Bulletin. 19:210-213

Altogether, 123 specimens of yellowtail kingfish were collected in ocean waters offshore from Sydney, N.S.W. and analysed for total and methyl mercury. Only 111 of these were analysed for selenium. The mean total mercury concentration of muscle tissu

Use of Background Correction to Improve the Accuracy of the Selective Reduction Method for Determining Methyl Mercury in Fish

Autor: Jurgen L Kacprzak, Ramon Chvojka

Publikováno v: Journal of AOAC INTERNATIONAL. 62:1179-1181

Background correction is used with a previously published flameless atomic absorption method for the concurrent determination of inorganic and methyl mercury. The use of background correction simplifies the procedure, but, more importantly, eliminate
