Summary: This study aimed to estimate the water-soluble concentration and pollution levels of heavy metals in road dust in Zhengzhou city, as well as identify their sources. The results showed that Cu and Zn had the highest concentrations, while Hg, Cd, and Pb had the lowest concentrations. Pollution indices indicated high levels of contamination for Cu and Cd, but lower levels for Cr and Pb. The UNMIX model identified natural sources, copper mine tailing contamination, agricultural activities, air pollution, and industrial activity as the major sources of dissolved heavy metals. It is crucial to implement immediate pollution control measures due to the presence of these metals in the dust.

Summary: Surface sediment and water samples were collected from Musa Estuary and analyzed for metals concentrations using ICP-MS. Cd had the highest contribution to ecological risk (49% based on PERI index). The Tessier procedure revealed that with increasing contamination, exchangeable and carbonate fractions of Cd, Pb, Ni, Zn, and Cu increased. Cd and Pb were found to have a high risk of release based on the mobility factor and individual contamination factor indices. Cluster analysis showed different sources for different metals. The adsorption of Co, Ni, V, and Zn to sediments was influenced by Eh/pH, DOC/temperature, and salinity.

Summary: Renewal of aging water infrastructure in urban areas offers opportunities for implementing green infrastructure (GI) systems. However, historical soil contamination and connections to road systems can mobilize legacy pollutants, such as lead, into GI installations. Soil metal chemistry and accumulation patterns were investigated in six Pittsburgh GI installations, with trace metals accumulating at roadside edges and potential remobilization of historically contaminated soils. These findings highlight the importance of understanding metal transport and sequestration in GI systems for effective stormwater planning and management.

Summary: The purpose of the research was to investigate the impact of selected organic materials on the energy concentration, energy of lactation, and energy yield of two grass species. The study found that the application of mineral fertilizer and compost extract led to a decrease in net energy concentration, while the use of humus extract with NPK resulted in the highest net energy of lactation. The yield of energy was highest when biological extracts were applied with NPK. However, weather conditions and environmental factors also influenced the feed energy values. Practical field experiments are necessary to identify the optimal fertilizer combinations for a specific region.

Summary: The aim of this experiment was to evaluate the impact of different organic materials on the yield of Dactylis glomerata, the content of selected macroelements (K, Ca, and Mg), and the ratios of K:Ca, K:Mg, and K:(Ca + Mg). Dactylis glomerata is a common forage plant in Poland due to its rapid growth, resistance to various conditions, and adaptability to meadows, pastures, and grasslands. A three-year pot experiment was conducted in a greenhouse, involving the application of organic materials (chicken manure, mushroom substrate, and rye straw) mixed with soil before the experiment. The results showed that the use of mineral and organic fertilizers significantly increased the yield of Dactylis glomerata, with the highest biomass yield observed in the groups treated with manure, straw, and mineral fertilizers, as well as mushroom substrate, rye straw, and mineral fertilizers.
