宏观元素的浓度(Ca,K,Mg,和Na),必需微量元素(Cr,Cu,Fe,Li,Mn,Ni,和锌),和非必需的微量元素(铝,As,Cd,Pb,和Ti)在PernaPerna(L.1758)来自巴西东南部的贻贝被列为了解COVID-19大流行对沿海环境质量影响的基线参考。对于贝壳,大流行期间,所有采样点的宏观要素负荷都更大;然而,对于软组织,记录了相反的趋势。相反,外壳中微量元素的浓度低于大多数样品的定量极限,在大流行期间,它们在软组织中趋于减少。因此,COVID-19是一个短期保护事件,对贻贝产生了积极影响。该结果与在COVID-19后情景中监测沿海环境有关。
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.
