Titanium (Ti) is considered a contaminant of emerging interest, as it displays toxic potential and has been increasingly employed in everyday products, pharmaceuticals, and food additives, mainly in nanoparticle form. However, several knowledge gaps are still noted, especially concerning its dynamics in the water. In this context, this study aimed to quantify total Ti concentrations in highly consumed swimming crabs, squid, and shrimp from an important estuary located in southeastern Brazil. Ti concentrations were higher than those reported in most studies carried out worldwide. Animal length and weight, as well as, depth, transparency, dissolved oxygen, and salinity, significantly influence Ti concentrations in the animals. Human health risks were also noted after calculating a simulated exposure to titanium dioxide, especially considering the uncertainties regarding the effects of this element and the absence of regulatory limits.
钛（Ti）被认为是一种新兴关注的污染物，因为它具有潜在的毒性，并且越来越多地被用于日常产品、药品和食品添加剂中，主要以纳米颗粒的形式存在。然而，仍有一些知识空白需要注意，特别是关于它在水中的动态。在这种情况下，本研究旨在量化巴西东南部一个重要河口的高消费游泳蟹、鱿鱼和虾中的总钛浓度。Ti 浓度高于世界上大多数研究报告的浓度。动物的长度和重量，以及深度、透明度、溶解氧和盐度，显著影响动物体内的 Ti 浓度。在计算模拟暴露于二氧化钛后，也注意到了人类健康风险，特别是考虑到关于该元素的影响的不确定性和缺乏监管限制。
