Summary: This study investigates the physicochemical properties and heavy metal variations in sludge from sewage treatment plants in industrial and non-industrial cities in Haryana, India. The results show that the sludge from industrial sites has higher concentrations of Cd, Ni, and Cr, and poses a higher ecological risk compared to sludge from non-industrial sites. pH, total carbon, and phosphorus are important factors controlling the binding and removal of heavy metals in sludge.

Summary: The Osun River, one of Nigeria's UNESCO-designated World Heritage Sites, is facing severe degradation of its biological water quality due to gold mining activities. The physiochemical water quality of the river has significantly deteriorated, with extremely high levels of total suspended solids, low water transparency, and low dissolved oxygen. The presence of heavy metals in the river has also exceeded permissible limits, posing a risk to freshwater biodiversity and human health.

Summary: Heavy metal accumulation in soil and water is a major problem caused by inorganic contaminants, impacting food security and human health. Phytoremediation approaches, considered safe and environmentally friendly, have been extensively discussed in this review which also highlights research gaps and advocates for the use of 'omics' studies in selecting potential plants for remediation.

Summary: The study revealed elevated concentrations of heavy metals in grains and processed products in the Arequipa region of Peru, with some products exceeding standard limits. Processed rice and products showed adverse effects according to Total Hazard Index, while certain products had unacceptable cancer risks based on Total Target Cancer Risk analysis. The presence of significant pollution levels due to lead in processed products was also detected.

Summary: This study analyzed the contamination load of six vegetables collected from five cultivated sites and two market sites in Delhi, India. The concentrations of heavy metals in soil and water samples were generally below the permissible level, except for slightly higher levels of Cd. Spinach had the highest pollution index value, while tomato had the lowest.

Summary: This study focused on evaluating the risk assessment of heavy metal contamination in aquatic ecosystems in Egypt's Suez Gulf coast. The results showed that Cd and Pb are severely enriched in surface sediment from anthropogenic sources, while Al, Mn, Fe, Cr, Co, Ni, Cu, and Zn predominantly originate from natural sources.

Summary: This study analyzed uptake and partitioning patterns of Cu, Zn, Cd, and Pb in saltmarsh taxa globally, finding that most plants accumulate metals in roots, with Cd accumulating more in Juncaceae. Some closely related taxa of salt-secreting species have lower Zn in leaves, possibly due to co-excretion of Na+ and Zn2+ through glands.

Summary: The expansion of industries and intensive agriculture have led to increased levels of heavy metals in the environment, posing potential risks to human health. Despite several available methods for removing heavy metals, most of them are expensive and difficult to perform. This review provides an overview of the presence of heavy metals in various food sources and highlights the current global situation.

Summary: The Phyllostachys pubescens macrophyte, also known as Moso Bamboo, was evaluated in laboratory conditions for its potential to restore copper-polluted soil. The study found that the Moso Bamboo had an average growth rate of 0.47 cm/day with a irrigation flow of 1.644 mm/d. Over a twelve-week irrigation period, the Moso Bamboo showed tolerance to copper-polluted water and was able to remove 51.4% of copper from the soil. The results suggest that the phytoextraction technique using Phyllostachys pubescens could be considered for the restoration of copper-contaminated soils in Mediterranean conditions.

Summary: Phytoremediation is an efficient method for managing toxic elements in contaminated soils. This study assessed the ability of three Brassica genotypes to remediate Cd contaminated soils, with results showing that B. juncea was the most tolerant genotype and had the highest biomass production and Cd accumulation. The findings suggest that B. juncea has the potential to be used for decontamination of Cd spiked soils and prevent its entry into the food chain.

Summary: Wildfire can induce long-term impacts on soil organic matter quality, with neutral sugars potentially serving as indicators post-fire. High-severity fires result in decreased soil sugars and increased contribution of recalcitrant carbon, indicating significant changes in soil organic matter composition.

Summary: This study evaluated the combined effect of microplastics and cadmium on a soil-plant system, finding that microplastics and/or cadmium can affect plant growth and yield, as well as the accumulation of cadmium in the roots and soil. The increased bioavailability of cadmium due to microplastics presence may explain the observed negative effects on soil properties and strawberry plant performance.

Summary: This study evaluated the effect of different harvest dates of calafate clones in the south-central zone of Chile on the polyphenolic content, antioxidant capacity, quality parameters, and fruit yield. The results showed that clone 2 harvested at 140 days after full bloom had the highest concentration of soluble solids, total polyphenol content, and anthocyanin concentration.

Summary: Microplastics (MPs) can spread contaminants and affect plant growth and yield. The presence of MPs and copper (Cu) nanoparticles led to decreased plant height, stem diameter, and root surface area in strawberry plants. The inflorescence number, fruit weight, and biomass were lower in the presence of MPs or Cu nanoparticles. The activity of soil enzymes was also affected by the combined application of MPs and Cu nanoparticles.

Summary: Despite the expansion of forest plantations in Chile, their impact on soil biology has been poorly studied. This research evaluated the changes in microbial composition and enzyme activity after the conversion of native forest to fast-growing species and cropping. Soil organic matter, phosphorous, calcium, boron, and water-holding capacity were found to be key factors influencing microbial abundance and diversity. More research is needed to fully understand the connection between soil factors and microbial community composition.
