The new context of the intensive use of lithium-based batteries led to increased production of Li and Li-containing wastes. All these activities are potential sources of environmental pollution with Li. However, the negative impact of Li on ecosystems, its specific role in the plants' development, uptake mechanism, and response to the induced stress are not fully understood. In this sense, the Li uptake and changes induced by Li exposure in the major and trace element contents, photosynthetic pigments, antioxidant activity, and elemental composition of were also investigated. The results showed that grown in Li-enriched nutrient solutions accumulated much higher Li contents than those grown in spring waters with a low Li content. However, the Li bioaccumulation factor in grown in Li-enriched nutrient solutions was lower (13.3-29.5) than in spring waters (13.0-42.2). The plants exposed to high Li contents showed a decrease in their K and photosynthetic pigments content, while their total antioxidant activity did not change substantially.
锂基电池的大量使用带来了新的情况，导致锂及含锂废物的产量增加。所有这些活动都是锂造成环境污染的潜在来源。然而，锂对生态系统的负面影响、其在植物生长发育中的具体作用、吸收机制以及对诱导胁迫的响应尚未完全了解。从这个意义上讲，还研究了锂暴露引起的锂吸收以及主要和微量元素含量、光合色素、抗氧化活性和元素组成的变化。结果表明，在富含锂的营养液中生长的植物积累的锂含量比在低锂含量的泉水中生长的植物高得多。然而，在富含锂的营养液中生长的植物的锂生物积累系数（13.3 - 29.5）低于在泉水中生长的植物（13.0 - 42.2）。暴露于高锂含量的植物其钾和光合色素含量降低，而其总抗氧化活性没有实质性变化。
