Summary: The study evaluated the potential of Rhizophora apiculata leaves in phytoremediation and biomonitoring of potentially toxic metals in two rivers in Peninsular Malaysia. It concluded that the leaves have a higher potential for phytoremediation of Cu, Zn, and Fe, while the mangrove plants are better at phytoremediation of Pb and Ni. The leaves also showed potential as biomonitoring agents, with positive correlations between PTMs in the leaves and sediment.

Summary: Soil and water in Egypt are contaminated with various pollutants, including fertilizer misuse, industrial effluent, wastewater discharge, and mining activities. These pollutants have adverse effects on air, water, food, and human health. Some plants, called hyperaccumulators, have the potential to remove pollutants from soil and water at a low cost. This review focuses on the application of trees in the phytoremediation of salts and heavy metals in Egypt.

Summary: Endophytic bacteria isolated from the roots of mangrove plants belong to multiple genera and possess pharmacological properties in their ethyl acetate extracts. Gas chromatography-mass spectrometry analysis identified major volatile organic compounds in the extracts of three high bioactive strains. Genome analyses revealed biosynthesis gene clusters of secondary metabolites of the bacterial endophytes.

Summary: The propagule dispersal pattern of two common mangrove species, Avicennia marina and Rhizophora apiculata, was studied at a mangrove fringed coast. The study found that A. marina had a higher dispersal rate and better growth compared to R. apiculata. However, both species failed to establish at the study site due to strong wave current and unfavourable soil condition.

Summary: Arbuscular mycorrhizal fungi (AMF) play a crucial role in enhancing phytoremediation of cadmium (Cd) pollution in plants. However, the function of AMF is influenced by phosphorus (P) concentration. This study investigated the regulatory effects of AMF on the Cd accumulation in Phragmites australis (P. australis) under different P levels. The results showed that AMF promoted plant Cd tolerance and detoxification by enhancing P uptake, Cd passivation, Cd retention in the cell wall, and functional group modulation. Additionally, AMF up-regulated the expression of specific genes to promote cadmium uptake at different phosphorus levels. The Cd response mechanism of the AMF-P. australis symbiotic system was found to be dependent on P concentration.

Summary: Microplastics are emerging pollutants that have become a global environmental issue. This study investigated the effects of polyethylene (PE) additions and heavy metal-contaminated soil on the growth and heavy metal accumulation of two hyperaccumulators. PE influenced soil pH, enzyme activities, and heavy metal bioavailability. It also affected plant growth, morphology, and heavy metal content. Overall, PE had negative effects on the soil environment, plant growth, and phytoremediation efficiency of cadmium (Cd) and lead (Pb).

Summary: Pollution of the environment by heavy metals (HMs) is a global issue, affecting the health of all living organisms. Human activities, such as industrialization and urbanization, are the major causes of HM release into the environment. Traditional methods to reduce HMs in polluted environments are inefficient and expensive, while phytoremediation, using hyper-accumulator plants, is a highly efficient, cost-effective, and ecofriendly alternative.

Summary: This study evaluated the potential of mangrove plants in purifying polluted ecosystems. The results indicate that these plants are capable of storing metals in their tissues and reducing the risk of certain metals. Among them, Avicennia officinalis performed well in metal extraction.

Summary: This study aims to determine the various phylloplane fungi available from mangrove plant R. apiculata leaves and their potential use against Fusarium oxysporum f. sp. cubense (Foc) in banana plants. Three phylloplane fungi, Lasiodiplodia theobromae, Trichoderma harzianum, and Nigrospora sphaerica, were found to have antagonistic potential against Foc. In in vivo tests, the treatment with Lasiodiplodia theobromae showed the best inhibition of disease incidence.

Summary: The intercropping of Moso bamboo and Sedum plumbizincicola can increase the removal efficiency of heavy metals from polluted soils, reduce the content of organic matter, available nutrients, and heavy metals in the soil, and increase bacterial diversity.

Summary: The study investigated heavy metal contaminations in water and sediments of the Golmarz wetland in northwestern Iran, showing no contamination in water but high levels of Se and As in sediments. Plants like Typha latifoila, Panicum maximum, and Scirpus lacustris have shown potential for bioaccumulation and phytoremediation of heavy metals in the environment, with high activity of antioxidant enzymes and phenol and flavonoids indicating plants' defense mechanisms against heavy metal pollution.

Summary: With the increasing demand for electronic devices, e-waste containing hazardous heavy metals is becoming a major environmental threat. This study evaluates the phytoremediation potential of Cyperus rotundus L. in soils contaminated with battery scrap waste (BSW), specifically for the heavy metals cadmium (Cd) and lead (Pb). The results showed that BSW mixing significantly increased the heavy metal content in the soil, resulting in reduced growth and biochemical traits of C. rotundus. However, C. rotundus was found to be a hyperaccumulator plant capable of absorbing Cd and Pb, making it a potential candidate for phytoremediation of BSW-contaminated soils.

Summary: Mangroves have high ecological service value and play a crucial role in achieving carbon neutrality. However, the ecological services provided by mangroves are declining due to the threat of pollutants, particularly heavy metal (HM) pollution. Researching the status and history of heavy metals in mangrove sediments helps in understanding how to protect mangroves.

Summary: This study assessed the capability of soil in retaining and transporting Al3+ in agricultural land in Trang Bom District, Vietnam. It developed maps and concluded that the soils in the area have high capability in retaining and transporting Al3+. These maps are useful for decision-making in determining the appropriate dose and frequency of chemical products for each soil capability zone.

Summary: This paper demonstrates the application of coupled reaction-diffusion equations with nonlinear reaction terms to heterogeneous landscapes, focusing on the dispersal of disease-vector mosquitoes and the spread of diseases. Realistic biological dispersal behavior is taken into account through chemotaxis terms, generating complex movement patterns. Numerical simulations using a general-purpose finite-element solver constructed from geographic information system data illustrate the assessment of control measures.
