Plastic resin pellets were collected from coastal areas (n = 7) of central Chile. Pellets were analyzed using Fourier-transform infrared spectroscopy for polymer identification and gas chromatography-mass spectrometry for Persistent Organic Pollutants (POPs) determination. Screened compounds were PBDEs (n = 10), PCBs (n = 7), and OCPs (n = 13). Pellets were only found at Lenga Beach (San Vicente Bay), which is likely influenced by the presence of industrial activities in the surrounding coastal area. The diameter of the pellets was 4.0 ± 0.6 cm (n = 370), the color varied from white (32%) to yellowing (68%), and the most prevalent polymer identified was high-density polyethylene (99%). POPs concentrations (ng/g-pellet) ranged from 10 to 133 for Ʃ10PBDEs, from 3 to 60 for Ʃ7PCBs and between 0.1 and 7 for DDTs. Levels of POPs are consistent with other investigations around the world and highlight the sorbtion capacity of plastics resin pellets, and consequently transport of POPs into coastal environments.
从智利中部沿海地区（n=7）收集了塑料树脂颗粒。使用傅里叶变换红外光谱法对聚合物进行了分析，并用气相色谱-质谱法对持久性有机污染物（POPs）进行了测定。筛选出的化合物包括 PBDEs（n=10）、PCBs（n=7）和 OCPs（n=13）。仅在伦加海滩（圣文森特湾）发现了颗粒，这可能是由于周围沿海地区存在工业活动的影响。颗粒的直径为 4.0±0.6 厘米（n=370），颜色从白色（32%）到泛黄（68%）不等，最常见的聚合物是高密度聚乙烯（99%）。POPs 浓度（ng/g-颗粒）范围为 10 至 133 ng/g-颗粒，用于 Σ10PBDEs，3 至 60 ng/g-颗粒，用于 Σ7PCBs，0.1 至 7 ng/g-颗粒，用于 DDTs。POPs 水平与世界各地的其他调查结果一致，突出了塑料树脂颗粒的吸附能力，以及 POPs 向沿海环境的传输。
