The concentrations of macro elements (Ca, K, Mg, and Na), essential trace elements (Cr, Cu, Fe, Li, Mn, Ni, and Zn), and nonessential trace elements (Al, As, Cd, Pb, and Ti) in the shell and soft tissues of Perna perna (L. 1758) mussels from Southeast Brazil are presented as a baseline reference for understanding the effects of the COVID-19 pandemic on the quality of coastal environments. For shells, the macro elements load was greater during the pandemic period at all sampling sites; however, for soft tissues, the opposite trend was recorded. On the contrary, the concentrations of trace elements in the shell were below the limit of quantification in most samples, and they tended to decrease in the soft tissues during the pandemic. Thus, the COVID-19 was a short-term conservation event that positively impacted the mussels. The results are relevant for monitoring the coastal environment in a post-COVID-19 scenario.
本研究旨在为了解新冠疫情对沿海环境质量的影响提供基础参考，分析了来自巴西东南部的贻贝（Perna perna (L. 1758））壳和软组织中的常量元素（Ca、K、Mg 和 Na）、必需微量元素（Cr、Cu、Fe、Li、Mn、Ni 和 Zn）和非必需微量元素（Al、As、Cd、Pb 和 Ti）的浓度。结果表明，在所有采样点，疫情期间贻贝壳中的常量元素负荷均有所增加，而软组织结构中的常量元素负荷则呈相反趋势。相反，壳组织中的微量元素浓度在大多数样本中低于定量限，且在疫情期间呈下降趋势。因此，新冠疫情是一次短期的保护事件，对贻贝产生了积极影响。这些结果对于后疫情时代监测沿海环境具有重要意义。
