Hepatic tissue of sampled on the coastline of the state of Santa Catarina in Brazil between October 2016 and May 2018 was used to evaluate intraspecific trends and spatial distribution of essential trace elements (Mn, Co, Cu, Zn, Mo and Cr) and non-essential trace elements (As, Pb, Cd, Hg, Ba and V). Principal Component Analysis (PCA) indicated differences in the bioaccumulation of trace elements between female adults and male adults, differences to sex and age were indicated by Kruskal-Wallis test. Heat maps suggest hot spots in locals with high concentration of trace elements in liver of . In general, the concentration of trace elements were comparable with values reported in other studies carried out for this species in South America and other regions of the world. The heat maps showed to be a promising tool to identify influences of the locality on bioaccumulation of trace elements in .
2016年10月至2018年5月期间，在巴西圣卡塔琳娜州海岸采集的肝脏组织用于评估必需微量元素（锰、钴、铜、锌、钼和铬）和非必需微量元素（砷、铅、镉、汞、钡和钒）的种内趋势和空间分布。主成分分析（PCA）表明成年雌性和成年雄性之间微量元素生物累积存在差异，Kruskal-Wallis检验表明了性别和年龄的差异。热图显示了肝脏中微量元素浓度高的地区存在热点。总体而言，微量元素浓度与在南美洲和世界其他地区对该物种进行的其他研究报告的值相当。热图显示是一种很有前景的工具，可用于识别地点对某生物体内微量元素生物累积的影响。
