The influence of different chelates applied in the soil primary on Al and secondary on Fe and Mn mobilization and their removal from solution was investigated. The work compared the efficiency of 10 mM tartaric acid and 3 mM EDTA in soil washing process and accumulation potential of Pistia stratiotes in rhizofiltration process. The plant response on the toxic element Al and other elements Fe and Mn was determined through the nitrogen and free amino acids content in plants. The efficiency of chelates decreased in order 10 mM tartaric acid > deionized water > 3 mM EDTA for all studied elements. P. stratiotes was able to remove up to 90% of elements during the 15 days period. Higher content of toxic element Al and potential toxic elements Fe and Mn were observed in the roots than in the leaves with the increased time. The trend of Al accumulation correlated with Fe accumulation (R2=0.89). Toxicity impact of high level of Al was observed by increased free amino acids (AA) level. Proline, histidine, glutamic acid and glycine were the most synthesised free AA in leaves. Total AA content in leaves was significantly higher under chelates addition compared to control. 相似文献

Faced with punishing severe offenders, why do some prefer imprisonment whereas others impose death? Previous research exploring death penalty attitudes has primarily focused on individual and cultural factors. Adopting a functional perspective, we propose that environmental features may also shape our punishment strategies. Individuals are attuned to the availability of resources within their environments. Due to heightened concerns with the costliness of repeated offending, we hypothesize that individuals tend towards elimination-focused punishments during times of perceived scarcity. Using global and United States data sets (studies 1 and 2), we find that indicators of resource scarcity predict the presence of capital punishment. In two experiments (studies 3 and 4), we find that activating concerns about scarcity causes people to increase their endorsement for capital punishment, and this effect is statistically mediated by a reduced willingness to risk repeated offenses. Perceived resource scarcity shapes our punishment preferences, with important policy implications. 相似文献
