Summary: The study showed that foliar application of MWCNT at concentrations up to 250 mg L-1 can alleviate Pb and Cd-induced toxicity and enhance the phytoremediation properties of pot marigold plants. However, higher concentrations of MWCNTs at 500 and 1000 mg L-1 exacerbated oxidative damage and reduced the accumulation of Pb and Cd in pot marigold seedlings. The research highlights the potential of MWCNTs to assist in phytoremediation of heavy metal polluted soils but also raises concerns about the toxic effects of high concentrations on plant physiology.

Summary: Increased levels of metal ions in human seminal fluid have a significant correlation with male fertility. Different metals have different effects on semen parameters and assisted reproductive treatments. Lower iron levels were associated with pathological spermiograms, while higher zinc, calcium, and magnesium levels were associated with normozoospermics. Longer sexual abstinence was correlated with higher zinc and magnesium levels. Lower vanadium levels were associated with higher fertilization rates. Patients who did not reach 100% embryo cleavage rate had higher lead and vanadium values. Lower levels of aluminium and sodium were associated with better blastocyst rates. The implantation rate showed inverse associations with women's age, iron, and calcium content, but positive associations with magnesium and sodium. Positive pregnancy evolution was associated with higher zinc, calcium, potassium, and magnesium levels. This study confirms the positive-negative effects of zinc, iron, calcium, sodium, aluminium, magnesium, vanadium, and lead on reproduction and suggests that the analysis of metals in semen is a new line of study for male fertility with implications on reproductive outcomes.
