Summary: The spike is the main organ contributing to lead accumulation in wheat grains, but the role of awn in wheat grain lead absorption is unclear. A field experiment was conducted to investigate this, and the results showed that the removal of awns decreased wheat yield by 4.1% and significantly lowered the grain lead accumulation rate. Awns were found to play an important role in wheat grain lead absorption during the late grain-filling stage. It was suggested that planting awnless or short-awn wheat varieties could be an effective measure to reduce the health risks of lead in wheat.

Summary: In agroecosystems, atmospheric heavy metal deposition has increased and poses risks to crop safety and human health. A field survey in Hebei Province, North China, revealed that wheat grown in districts with industrial and traffic pollution accumulated more lead from soil and atmospheric deposition, with the highest accumulation in the bran. Laser ablation inductively coupled mass spectrometry showed that lead mostly accumulated in the pericarp and seed coat of wheat grains.

Summary: A field experiment was conducted to explore the foliar uptake of Pb in Chinese cabbage exposed to atmospheric fallout. It was found that the major source of Pb in cabbage leaves was PM2.5, with high-Pb-accumulation cabbage trapping more PM2.5-Pb and accumulating more Pb.

Summary: Atmospheric deposition is a crucial pathway for heavy metals (HMs) to accumulate in agricultural soils. This study investigated the effects of atmospheric deposition on soil HMs accumulation at a regional scale. Industrial activities significantly increased the flux of deposited particles from atmospheric deposition, with higher fluxes in industrial areas compared to agricultural areas and reference sites. Although the deposition fluxes of HMs were decreasing over time, Cd and Pb still remained at high levels in the study area. Precipitation was found to be the key factor affecting seasonal variations of atmospheric HMs deposition. Lead isotope analysis revealed that atmospheric Pb originated from coal combustion and atmospheric deposition was the main source of Pb contamination in agricultural soils near industrial areas. This study provides valuable insights into the impacts of atmospheric deposition on HMs accumulation in agricultural soils and offers a theoretical basis for preventing soil HMs contamination in industrial developed regions and similar areas.

Summary: Increasing acid deposition and intense nitrogen fertilization have led to severe soil acidification, with unbalanced plant uptake of anions and cations being the primary source. Fertilization accelerates soil acidification by increasing leaching of NO and base cations, as well as plant uptake and harvest removing cations. Plant redistribution of cations in soils plays a significant role in soil acidification.

Summary: In low Pb soils, splash and atmospheric deposition accounted for 84% and 78% of lettuce Pb in NYC and Ithaca, respectively. In high Pb soils, splash and atmospheric deposition accounted for 88 and 93% of Pb on lettuces, with splash being the dominant mechanism. Soil covers were shown to be effective at significantly (p < 0.05) reducing lettuce Pb contamination, and mulching is strongly recommended as a best practice.

Summary: This study investigated the relationship between atmospheric emission, deposition, and soil Cd accumulation in the Middle-Lower Yangtze Plain in China. The results showed that the soil Cd accumulation rate in the study area exceeded the national average and continued to accumulate in recent decades. The contribution of atmospheric deposition flux to Cd increment in the soil was in the range of 22-29%, with the atmospheric deposition flux decreasing over time.

Summary: This study investigated the quantity and characteristics of microplastics (MPs) in the soil environment of two conservation areas in southeastern Australia. The results showed that both atmospheric deposition and trail surfaces in these areas contained MPs, with the majority being fibers. MPs were attributed to clothing, footwear, litter, and diffuse sources. Minimizing and preventing MP pollution is complex due to multiple direct and diffuse sources, as well as various factors influencing MP deposition and retention in the environment.

Summary: This study analyzed organically bound strontium isotope ratio (Sr-87/Sr-86) in litter and soil collected from forest ecosystems in Japan and found that geological conditions and atmospheric deposition were important factors affecting the geographical distribution of Sr-87/Sr-86 in litter and soil. These factors indirectly influenced soil acidity and base cation concentration.

Summary: This study investigates the impact of atmospheric cadmium pollution on the accumulation of cadmium in wheat grains, and finds that wheat leaves can directly absorb atmospheric cadmium through stomata and transport it to grains. The critical period for leaf cadmium accumulation is the early filling period, and its contribution decreases as filling progresses. The stored cadmium in leaves before flowering and the newly absorbed atmospheric cadmium after flowering contribute to cadmium accumulation in grains. Therefore, controlling atmospheric cadmium pollution sources and reducing cadmium absorption by leaves during grain filling can effectively control cadmium pollution in wheat grains.

Summary: Contaminated soil in urban residential areas, particularly in Brooklyn and Manhattan of New York City, poses a serious risk to children's health due to high concentrations of lead (Pb). The study found that the Pb concentrations in backyard soils were three times higher than the outdated EPA soil hazard standard, while the Pb content in tree pits and public parks was significantly lower. The research also revealed that the Pb in the soil was highly bioavailable, indicating its potential to be absorbed by children.

Summary: The study aimed to investigate the pollution source of heavy metals (HMs) in soil near mining and evaluate the influence mechanism of dust fall on HMs pollution. The results showed that dust fall is the primary pollution source to HMs accumulation in soil. Mineralogical analysis revealed that quartz, kaolinite, calcite, chalcopyrite, and magnetite are the major mineral phases in dust fall.

Summary: In this study, the impact of rice straw return or removal on the accumulation of heavy metals in the soil-rice system was investigated. The results showed that straw return increased the soil pH and organic matter content, but decreased the soil redox potential. On the other hand, straw removal effectively reduced the concentration and bioavailability of Cd in contaminated farmland.

Summary: The study found that wheat leaves and ears can directly absorb atmospheric deposition lead through stomata, and wheat with defoliated leaves showed significantly reduced lead absorption. Lead isotope analysis showed that ears contributed the most to grain lead, followed by leaves and roots. Different organs had different dominant contribution periods to grain lead accumulation, with leaves and ears contributing mainly in the early and late filling stages.

Summary: The removal of wheat flag leaf significantly reduces the concentration of Pb in grains, where the contribution of flag leaf to grain Pb accumulation decreases gradually with the filling process. The main source of Pb from flag leaves to grains is found to be from atmospheric fallout in fine particles, suggesting that measures to reduce the influence of fine atmospheric particles on wheat could effectively control Pb contamination in wheat grains.
