species are known for their capacity to accumulate toxic elements, which may pose environmental risks and limit their use. Arsenic accumulation in may vary in response to environmental and physiological conditions. Moreover, interactions between chemical elements may result in synergistic or antagonistic effects. This study determined the variability in the concentration of macroelements (N, P, K) and microelements (As, Cd, Pb, Cu, Zn, and Mn) through time and between growth stages in from a site adjacent to a phosphorite deposit in the Gulf of California. A generalized linear model (GLM) was performed to assess the influence of other concurrent elements, polysaccharides (alginate and fucoidan), and their main functional groups (uronic acids and sulfate) on arsenic content. Elemental concentrations showed the following decreasing order: N > K > P > Fe > Mn > Zn > Cd > As > Cu > Pb. Arsenic concentration was 4.33 ± 0.20 mg kg. Significant differences in element concentrations were found by month and growth stage. The main variables associated with arsenic accumulation in were potassium, nitrogen, zinc, fucoidan, sulfate from fucoidan, and alginate. The implications of the arsenic, cadmium, and lead concentrations in and its potential applications in food, feed, and agricultural contexts are discussed. This research sheds light on the dynamic nature of elements accumulation in emphasizing the need for a comprehensive and context-specific understanding of elemental variations within for safe and responsible applications.

墨西哥加利福尼亚湾马尾藻（Ochrophyta、Phaeophyceae）中砷含量与大量元素、微量元素和多糖的关系

物种以其积累有毒元素的能力而闻名，这可能会造成环境风险并限制其使用。砷的积累可能因环境和生理条件而异。此外，化学元素之间的相互作用可能导致协同或拮抗作用。这项研究确定了邻近磷矿矿床地点的常量元素（N、P、K）和微量元素（As、Cd、Pb、Cu、Zn 和 Mn）浓度随时间和生长阶段之间的变化。加利福尼亚湾。采用广义线性模型（GLM）评估其他并发元素、多糖（海藻酸盐和岩藻依聚糖）及其主要官能团（糖醛酸和硫酸盐）对砷含量的影响。元素浓度呈现以下递减顺序：N>K>P>Fe>Mn>Zn>Cd>As>Cu>Pb。砷浓度为 4.33 ± 0.20 mg kg。不同月份和生长阶段的元素浓度存在显着差异。与砷积累相关的主要变量是钾、氮、锌、岩藻依聚糖、岩藻依聚糖的硫酸盐和藻酸盐。讨论了食品、饲料和农业中砷、镉和铅浓度的影响及其潜在应用。这项研究揭示了元素积累的动态本质，强调需要对元素变化进行全面和特定背景的理解，以实现安全和负责任的应用。
