Within recent times, heavy metal contamination in rice (Oryza Sativa) has been of growing concern particularly due to its implications on human health via consumption. Twenty-one different brands of rice marketed in Trinidad and Tobago were investigated for their heavy metal content (Cd, Cr, Cu, Mn, Ni, Pb and Zn) using Flame Atomic Absorption Spectroscopy. Lead was not detected in any of the samples, while both Cadmium and Nickel were detected in only one sample each at 0.27 and 1.79 µg/g, respectively. The average metal concentrations decreased in the following order: Zinc > Manganese > Copper > Chromium with concentrations ranging from 1.00–4.35, 1.72–29.92, 5.87–43.56 and 0.06–1.16 µg/g, respectively. The target hazard quotient (THQ) and hazard index (HI) values for all samples were less than one, indicating no risk of non-carcinogenic effects to consumers.

在最近一段时间内，稻米（Oryza Sativa）中的重金属污染引起了越来越多的关注，特别是由于其通过消费。使用火焰原子吸收光谱法研究了特立尼达和多巴哥市售的二十一种不同品牌的大米的重金属含量（Cd，Cr，Cu，Mn，Ni，Pb和Zn）。在任何一个样品中均未检测到铅，而仅在一个样品中分别以0.27和1.79 µg / g的形式检测到了镉和镍。平均金属浓度按以下顺序降低：锌>锰>铜>铬，浓度范围分别为1.00–4.35、1.72–29.92、5.87–43.56和0.06-1.16 µg / g。所有样品的目标危险商（THQ）和危险指数（HI）值均小于1，这表明没有给消费者带来非致癌作用的风险。
