This research has explored the potential of stable isotope and trace metal profiles to distinguish Australian prawns from prawns imported from neighbouring Asian countries. Australian prawns were collected mostly from the Brisbane area. Strong differences in Australian vs. imported prawns were evident from both the isotope and trace element data, with the differences most likely occurring because imported prawns are typically reared in aquaculture facilities and frozen prior to sale in Australia. The aquaculture origins are characterised by comparatively; low δHVSMOW, δ(13)CVPDB values, low concentrations of arsenic, zinc and potassium, and high water contents (>80%). Relatively high arsenic and cadmium contents were found within Australian prawns, but the concentrations did not exceed local human health guidelines.
本研究探讨了稳定同位素和痕量金属谱区分澳大利亚对虾与从亚洲邻国进口对虾的潜力。澳大利亚对虾大多采集自布里斯班地区。从同位素和微量元素数据来看，澳大利亚对虾和进口对虾之间存在明显差异，这些差异很可能是因为进口对虾通常在水产养殖设施中养殖，并在澳大利亚销售前冷冻。水产养殖来源的特点是相对较低的δHVSMOW、δ(13)CVPDB值、较低的砷、锌和钾浓度以及较高的含水量（>80%）。在澳大利亚对虾中发现了相对较高的砷和镉含量，但浓度未超过当地人体健康指导标准。
