“…As pH tend towards acidity, ionization of metals increases. Metals in ionic form are readily absorbed by plants and animals [22], [23]. The variation in the uptake of Cu based on the source of water agrees with the work of Hossain et al, in 2017 [24], who got a similar result from three different O. niloticus farms in Bangladash.…”

This study was designed to assess the effect of relative metals concentrations, pH and species variations on the uptake of copper (Cu), iron (Fe), calcium (Ca) and magnesium (Mg) in water, fish and fish parts to monitor the toxicity potentials of consuming these fish. The water and fish samples were obtained from four locations (Farin gada stream, Lamingo Dam, Nasco pond and mining pond) in Jos Metropolis, Plateau State, Nigeria, Water and six fish species samples were collected from the four locations, digested and analysed using Buck Scientific Atomic Absorption Spectrophotometer, model 210VGP. Results show that pH of the water sources from Farin gada stream, Lamingo Dam, Nasco pond and mining pond were 7.1, 6.5, 7.0 and 7.2 respectively. The concentrations of Cu in the water sources were 0.030±0.001, 0.010±0.003, 0.020±0.000, 0.027±0.000 in Farin Gada stream, Nasco pond, Lamingo Dam and mining pond respectively; Fe were 2.2±0.1, 0.0±0,000, 0.2±0.003 and 0.3±0.001; Ca were 305±3.0, 37±1.5, 110±3.5 and 163±4.5; Mg were 160±3.6, 126±4.8, 79±1.9 and 95±2.8 in that order above. Different fish species from the same water source bioaccumulated Cu, Fe, Ca and Mg at varying concentrations depending on source, fish species or the physicochemical properties. Different fish species have different preferences as to which part (body, gills and head) of the fish these metals are concentrated more. Lamingo Dam had five fish species, mining pond had three, while Nasco pond and Farin Gada stream had one each. The results established that uptake and bioavailability of Cu, Fe, Ca and Mg by fish in water depend on species variation, relative concentration of the metals in the source of water and the pH of the water.

“…In the present study, all the aforementioned factors that favor copper absorption improved grain yield due to the increase in Cu absorption capacity. Thus, grain yield reached a maximum point close to that indicated in the literature, that is, 2 kg ha -1 (Karamanos et al, 2004;Chen et al, 2005;Chaves et al, 2010;Lange et al, 2016;Sun et al, 2019;Zabotto et al, 2020).…”

Conducting a field study to investigate the effects of foliar and soil fertilization with copper on the nutritional and physiological parameters and grain yield of common bean. The experimental design was a randomized block, in a 2 x 5 factorial scheme. The first factor was the site of application of copper fertilization. The second factor was copper doses: 0, 1, 2, 3, and 4 kg ha-1 (6 replicates). The following were evaluated: leaf nitrogen and copper contents, relative chlorophyll index (RCI), gas exchange, photochemical efficiency of photosystem II, and grain yield. The data were subjected to analysis of variance and F test (p-value < 0.05), using the Scott & Knott for qualitative data and polynomial regression for quantitative data. Leaf Cu content was higher with soil application (4% and 28%), both at 24 and 45 DAE, respectively. Net photosynthesis reached a maximum index of 18.77 µmol m-2 s-1 with foliar Cu fertilization at the dose of 4 kg ha-1. The application of 2.0 kg ha-1 Cu was the one that led to the highest grain yields; however, soil application stood out with a yield about 12% higher of the foliar. Soil fertilization proved to be more efficient in terms of Cu absorption and RCI rates, improving grain yield (12%) in relation to foliar, especially at the dose of 2 kg ha-1. The dose of 2 kg Cu ha-1 provided the best differential profit, reaching US$ 581.96 ha-1 and US$ 503.01 ha-1 for soil and foliar application, respectively.

“…Species belonging to different successional groups from the Brazilian Atlantic Forest have distinct Cu translocation capacities when cultivated in Cu-contaminated soils (Asensio et al 2019). The pioneer S. terebinthifolia accumulates Cu in roots, but shows low translocation to shoots, while the non-pioneer species E. uni ora shows greater translocation, and Cu accumulation occurs in both roots and shoots (Zabotto et al 2020).…”

“…Studies with several Atlantic Forest tree species cultivated in contaminated soil observed that the impacts on biometric parameters occur differently, depending on the species, concentration and time of exposure to excess copper (Silva et al 2010;Silva et al 2011;Caires et al 2011;Silva et al 2015;Marco et al 2016;Asensio et al 2019;Zabotto et al 2020). Excess Cu had negative effects on leaf dry biomass of the pioneer species S. terebinthifolia, but did not affect height or stem diameter, while the non-pioneer species E. uni ora showed no reduction in biomass but did show a decrease in height.…”

Context Soil pollution by heavy metals is a worldwide environmental concern. Owing to their proximity to anthropogenic emission sources, urban forest fragments are highly affected by the excessive input of heavy metals into the soil.Objectives This study aimed to assess the physiological and biochemical responses of two native Brazilian Atlantic Forest Schinus terebinthifolia Raddi (pioneer species) and Eugenia uniflora L. (non-pioneer species), when cultivated in soils contaminated with Cu. Methods Plants were cultivated in soils of an urban forest fragment contaminated with 0 (control), 60, 120, 180 or 240 mg Cu kg-1 soil. Growth variables, Cu content in plant tissues, translocation index, bioaccumulation factor, pigment contents, leaf gas exchange and chlorophyll fluorescence were all measured to assess physiological alterations resulting from copper stress, while the enzymatic (superoxide dismutase) and nonenzymatic (ascorbic acid and glutathione) antioxidants were quantified to assess the biochemical responses of the species. Results Both species presented high uptake and accumulation of Cu in roots with low translocation rates to shoots; however, S. terebinthifolia showed higher Cu restriction in roots than E. uniflora. S. terebinthifolia and E. uniflora showed distinct responses in growth and leaf gas exchange. The species showed neither difference in enzymatic contents nor oxidative reduction. Conclusion The restriction of copper in roots appears to be the principal protective mechanism against copper phytotoxicity, preventing negative effects on the physiological and biochemical status of the species. S. terebinthifolia shows potential as a Cu phytostabilizer, while the E. uniflora has potential as a Cu phytoextractor.
