Summary: Physical and chemical remediation techniques used in contaminated areas are expensive and damaging to the soil structure. Biological alternatives, such as phytoremediation, are economical and applicable to large areas. This study evaluates the ability of plant species adapted to Brazilian semi-arid conditions to grow in soils contaminated with Pb, and concludes that P. juliflora, A. peregrina, and U. ruziziensis are more suitable for cultivation in soils containing high levels of Pb.

Summary: This study investigated the uptake and distribution of cadmium, lead, and nickel by two Brassica cultivars grown on metal-contaminated soil. The results showed that the growth of the cultivars was affected, and irrigation with contaminated water led to a decrease in photosynthesis rate and chlorophyll content. However, one cultivar was less sensitive to the toxic elements and prevented their translocation, making it suitable for cultivation in PTE-contaminated soils.

Summary: Several international organisations have recommended the use of bioindicators to improve the evaluation of ecological risk in marine ecosystems. In this study, wild mussels were collected from thirty sampling points along the Asturias coastline and analyzed to identify the relationship between metal concentrations in mussel tissues and the geological and environmental conditions of the coastal area. The study revealed concentration trends for different metals and correlations between them. The mussels also showed natural defense against certain metals. Cluster analysis of the samples grouped them based on the sources of the metal concentrations. Both anthropic and natural sources have led to an increase in metal loads in mussels, sometimes exceeding international environmental criteria.

Summary: This study in Tyumen, Russian Federation aimed to investigate the effects of heavy metals accumulation in soil and plants, as well as the biochemical responses of plants to such accumulation. The concentrations of Cu, Zn, Fe, Mn, and Pb in soils exceeded background values, with Pb content at the battery manufacturing plant above permitted levels. Heavy metal accumulation was found to stimulate photosynthetic pigment synthesis and induce oxidative stress in cells. Plant phenolic and flavonoid compounds decreased in urban areas compared to control groups, while coltsfoot catalase activity showed both increases and declines. The findings suggest limitations on the medicinal use of coltsfoot due to heavy metal accumulation and biochemical responses.

Summary: Flooding can transport copper from stream sediments to adjacent riparian habitats. Copper is toxic to plants at high concentrations and can restrict plant growth. Invasive plants like Fallopia japonica, which are tolerant to heavy metals, modify riparian habitats. A comparison of the effects of copper on Fallopia japonica and native Urtica dioica plants showed that Fallopia japonica is more efficient at detoxifying internal copper concentrations and has a competitive advantage in polluted areas.

Summary: This study aimed to investigate the effect of amended compost on reducing heavy metal bioavailability in soil and relieving heavy metals stress on plants under Cu and Zn stress in a pot experiment. The application of amended compost could promote the growth and quality of pakchoi and enhance the stress ability of malondialdehyde and antioxidant enzymes to heavy metals. The distribution of Cu and Zn in different subcellular parts of pakchoi was also affected. The results showed that the application of amended compost significantly reduced the heavy metals content in the shoot of pakchoi, among which the content of Cu and Zn in the shoot of pakchoi in RLw was significantly decreased by 57.29% and 60.07%, respectively. These results provide a new understanding for efficient remediation of contaminated farmland soil by multiple heavy metals.

Summary: The world demand for cocoa beans has increased, but the spread of witches' broom disease poses a significant obstacle to cocoa production. Various strategies such as genetic control, cultural management, and chemical and biological control have been attempted in the field to combat the disease, but economic and technical difficulties remain to be overcome. Although the disease is currently restricted to Central and South America, measures need to be taken to prevent its spread to other regions to avoid a global crisis in cocoa production.
