The alga contains salt and heavy metals that are accumulated in algae poses a significant challenge to the safe use of algae in soil fertilization and other applications. This study examines the relevance of algal biomass as an environmentally friendly fertilizer, thereby contributing to sustainable coastal management practices. In this study, the hot and cold extraction method were done to obtain the Ulva rigida extract.

Environmental Quality Standards (EQS) derived under the European Water Framework Directive are legally binding and enshrined in individual European Member State Country national legislation. These EQS are derived following well-established guidance documents. In 2013, EQS for nickel were derived for freshwaters to be protective against long and short-term exposures, at 4 and 34 µg L-1, respectively.

The prominence of binuclear catalysts underlines the need for the design and development of diverse bifunctional ligand frameworks that exhibit tunable electronic and structural properties. Such strategies enable metal-metal and ligand-metal cooperation towards catalytic applications, improve catalytic activity, and are essential for advancing multi-electron transfers for catalytic application. Hereby, we present the synthesis, crystal structure, and photocatalytic properties of a binuclear Ni(II) complex, [Ni2(1,10-phenanthroline)2(2-sulfidophenolate)2] (1), which crystallizes in the centrosymmetric triclinic system (P-1) showing extensive intra- and inter- non-coordinated interactions.

Co-cropping of hyperaccumulators is still poorly understood, while associations between hyperaccumulators and other plant species may promote beneficial plant interactions and lead to increased metal phytoextraction from contaminated soils. The aim of this study was to evaluate the phytoextraction potential of the Ni-hyperaccumulator in different co-cropping combinations with and . Plants were grown in ultramafic soil in a growth chamber for 45 days and Al, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn concentrations in roots and leaves were analyzed.

Background: Previous research has demonstrated that exposure to individual heavy metals elevates the incidence rate of congenital heart defects (CHDs). However, there is a paucity of data concerning the relationship between combined exposure to multiple heavy metals and the occurrence of CHDs. This study seeks to investigate the association between combined heavy metal exposure in pregnant women and the incidence of CHDs in their offspring in Lanzhou, China.
