“…The major source of heavy metals incorporation into plant body and seed oil is the contaminated soil and irrigation water (Laila et al 2022). The accumulation of these metals causes a substantial decline in agricultural yield and productivity while the consumers experience serious health issues (Pruteanu et al 2022). Lead (Pb) and nickel (Ni)are non-essential elements whose contamination in the soil and water is becoming an escalating ecological and economical issue in Pakistan.…”

Heavy metal pollutants i.e. lead and nickel are introduced to cultivable land through many sources and get accumulated in the soil profiles and contaminate water bodies which affect the growth and production of several crops. Seaweeds are rich in nutrients and have the ability to improve soil fertility by adding nutrients and organic contents to soil. In this study, S. ilicifolium was used with and without plant growth promoting rhizobacteria (PGPR) P. aeruginosa which showed heavy metal biodegradation capacity of 99.06% for lead and 98.8% for nickel against said metal stress. The individual and combined treatment of Sargassum ilicifolium as soil amendment and P. aeruginosa improved sunflower growth under 0.5 mM lead (Pb) and nickel (Ni) contaminations. The morphological characteristics of plants including shoot and root length and fresh weight were improved under stress and non-stressed condition. The biochemical analysis of proline, total phenols, peroxidase (POD), superoxide dismutase (SOD) and DPPH-radical scavenging activity also indicated that plant tolerance was improved under heavy metal stress.

“…Copper intake in the body is provided by copper-rich foods such as vegetables, fruit [54][55][56], in meat products [57] or in cereals [1,2]. Drinking water also contributes about 0.12-0.26 mg (≈20%) [1] of copper to the average daily intake.…”

Drosophila melanogaster serves as a important research model both for genetic investigations and for the study of metal toxicity, facilitating the elucidation of physiological mechanisms comparable to those of human organisms. In our research, we evaluated the toxicity effect resulting from exposure to various concentrations of lead and copper on the prolificity rates throughout the life cycle (egg-adult) of four genotypes of Drosophila melanogaster: wild-type (control), white, brown, and white-vestigial. During our study, the prolificity rates were examined across three repetitions under the impact of exposure to concentrations of 0.50, 1.00, 2.00, and 4.00 mM of copper (CuSO4) and lead (Pb(C2H3O2)2). Prolificity rates throughout the life cycle exhibited variations as a direct consequence of genetic factors, the concentration of exposure, and the specific type of metal, either copper or lead. The mutant white-vestigial genotype revealed an IC50 concentration for prolificity inhibition at lower doses of 2.00 mM for copper and 4.00 mM for lead, in contrast to the control genotype (wild-type), which exhibited an inhibition concentration rate >IC50 of 4.00 mM only in the case of copper. Our results concluded that the (i) dose influences the prolificity rate in a directly proportional manner, (ii) comparative analyses between copper and lead revealed that copper displayed toxicity across all genotypes within the concentration range of 0.50 mM to 2.00 mM. In contrast, lead exhibited toxicity within the concentration range of 1.00 mM to 4.00 mM, highlighting a (iii) more acute toxicity characteristic in the case of copper. Thus, the results of this research reflect the importance of using Drosophila melanogaster as a genetic model in the comparative study of the interaction between genetic factors and the toxicity of metals, offering significant insights into monitoring their impact and defining the maximum permissible doses on organisms.

Environmental protection, global food security, and nutritional quality are critical issues for worldwide sustainable development. Plums (Prunus domestica L.), well-known for their rich nutritional content and distinct phytochemical profile, have received increased attention due to their potential health benefits. The present study evaluates the ecological and conventional management systems of quality parameters in three plum varieties—Tuleu Gras, Record, and Centenar—and establishes suitable practices to improve fruit quality and yields. The fruit morphometric features (color, firmness, soluble solid content, titratable acidity, and total sugar) were analyzed during their raw fruit state, while different fruit-sample extracts were assessed for phytochemical compounds and heavy metal concentrations, specifically, zinc, copper, nickel, and cadmium. The results show a wide variability in the examined characteristics among management practices that differentially accumulated throughout the ripening phase and significantly influenced the nutritional value of the plum fruit. The application of an ecological management practice yielded small plum fruits (38 g) and maintained a more consistent and vigorous fruit color compared with the conventional system (83 g). Moreover, ecological plums have higher antioxidant activities, total polyphenols, and flavonoids (21.70–25.54 µM Trolox/g of dw, 3.89–7.76 mg GAE/ g of dw, and 1.45–3.65 mg CE/g of dw, respectively). Among the content of metals in the plum fruit, copper exhibited the highest concentrations (0.83–1.21 mg/kg), while cadmium was detected at the lowest levels (0.006–0.009 mg/kg). The potential health implications of heavy metals, by calculating their estimated daily intake (EDI), target hazard quotient (THQ), and hazard index (HI), for both adults and children were also analyzed. The EDI values of accumulated elements in the plum fruits followed the order of Cu > Zn > Ni > Cd with no concern for human health (THQ and HI < 1). According to this study’s findings, fruit quality parameters are significantly higher in ecological plums, providing a compelling argument for adopting sustainable agricultural practices. These results highlight the importance of selecting sustainable agricultural practices, not only to safeguard the environment but also to ensure high-quality products suitable for human consumption.
