“…Compared to the existing literature, the results of this study differ in some aspects [24,25]. For instance, pepper has the highest comprehensive advantage index in this study, whereas, in other studies, its performance may vary due to differences in research areas and methods [26][27][28]. The performance of vegetables in this study is also superior to that in many other regions, likely due to the unique climatic conditions and soil characteristics of Hancheng City.…”

This study aims to provide a scientific basis for the development of county-level agricultural industries through a comprehensive evaluation of the environmental and economic benefits of agricultural products. Focusing on Hancheng City in Shaanxi Province, this paper calculates and analyzes the carbon emission intensity per unit output value and the economic benefits of major agricultural products, assessing their comprehensive advantage indices. The research methods include data collection, data processing, and model construction, utilizing a bi-factor matrix analysis to explore the balance between environmental sustainability and economic profitability of different agricultural products. The results indicate that pepper and vegetables have the highest comprehensive advantages, demonstrating significant economic and environmental benefits, while soybeans show lower comprehensive advantages, requiring improvements in cultivation techniques and management practices. Based on the research findings, this paper proposes policy and management recommendations for different agricultural products, including focusing on the development of high-comprehensive-advantage products, improving cultivation techniques for low-comprehensive-advantage products, promoting green agricultural technologies, establishing a carbon footprint monitoring system for agricultural products, and strengthening agricultural infrastructure construction. The study’s conclusions provide theoretical support and practical guidance for the agricultural development strategies of Hancheng City and similar regions, contributing to the achievement of sustainable agricultural development and carbon reduction goals.

“…No se encontró en ningún órgano concentraciones mayores a 100 mg kg -1 (umbral), de modo que el girasol no podría ser clasificada como una planta hiperacumuladora bajo este criterio (Baker et al, 2000). Sin embargo, se ha encontrado que la rotación de cultivos anuales como girasol para aceite, colza y maní, pueden extraer más Cd del que ingresa al sistema en un suelo agrícola (Yang et al, 2021).…”

El objetivo de esta investigación fue determinar la acumulación, distribución y tolerancia de cadmio (Cd) en girasol en suelos contaminados con dicho metal. La investigación consistió en dos experimentos conducidos en macetas bajo condiciones de invernadero. En el primero se probaron concentraciones de 0, 10, 15, 20 y 25 mg Cd kg-1 suelo y se evaluó la altura, producción de materia seca y concentración de Cd en raíz, tallo, hoja e inflorescencia a los 84 días. Para el segundo, la concentración fue de 20 mg Cd kg-1 suelo y se evaluó a los 35, 49, 63, 75 y 84 días la concentración de Cd en los mismos órganos. Las dosis de Cd no tuvieron efecto en la altura de planta ni en la producción de materia seca, siendo el índice de tolerancia (IT) equivalente a 1, lo que demostró su alta tolerancia por este metal. En general, se encontró que al incrementar las dosis de Cd en suelo aumentó la concentración de Cd en planta. Independiente a la época de evaluación, la raíz concentró más Cd debido a una baja translocación hacia la zona aérea. El factor de bioconcentración (FBC) fue mayor a 1 bajo las diferentes dosis de Cd. En tanto al factor de translocación (FT), este resultó menor a 1 en ambos experimentos. Según los valores del FT y FBC encontrados, el girasol se comportaría como un fitoestabilizador por debajo de 25 mg Cd kg-1 suelo.

“…Urbanization and industrialization are the primary reason for the cadmium contamination in soil. It will affect plant growth and intensively affect agriculture practices (Yang et al 2022;Kumar et al 2022). The cadmium concentration in this region varies from 1.25 to 2.78mg/kg, with a mean of 1.83 mg/kg.…”

“…The spatial analysis revealed that the lower chloride concentration was recorded in the southern and southwest parts, and the higher concentration of chloride was recorded in the eastern and northern parts of the study area (Fig 3f). The elevated concentration of chloride cause burning pain, redness, and blister on the skin and also affects the throat, nose, and eyes (Xiao et al 2022).…”

<p>The increasing industrialization and urbanization in recent times has led to a significant increase in heavy metal pollution in soil and sediment. The present study aims to evaluate the heavy metal contamination (HmC) in surface sediments collected from the Kosasthalaiyar River located between latitudes 13°12′03″N and 13°16′34″N and longitudes 80°18′6″E and 80°19′56″E. Ten sampling locations were selected in the study area and samples of surface sediments were collected and analyzed for 16 geochemical and heavy metal parameters, including Silver (Ag), Aluminium (Al), Calcium (Ca), Cadmium (Cd), Chloride, Cobalt (Co), Total Chromium (Cr), Copper (Cu), Mercury (Hg), Manganese (Mn), Molybdenum (Mo), Nickel (Ni), Lead (Pb), Silica (Si), Titanium (Ti), and Zinc (Zn). The study aims to determine the potential environmental hazards of heavy metals in the sediment through calculation of the potential environmental hazard index (RI). Assess the impact of human activities on HmC in the surface sediments using four pollution indices: the Geo-accumulation index (Igeo), the Contaminant factor (CF), the degree of contamination (DC), the potential contamination index (PCI), and the pollution load index (PLI) and Conduct a human health risk assessment (HHRA) of heavy metals in the sediment. The study results will provide insight into the contamination levels and help inform measures for controlling pollution and promoting sustainability in the area.</p>
