“…Sun ower is a major source of oil, biomass production, and is commercially utilized for chemical, energy and industrial purposes (Bayat et al 2021). The major source of heavy metals incorporation into plant body and seed oil is the contaminated soil and irrigation water (Laila et al 2022). The accumulation of these metals causes a substantial decline in agricultural yield and productivity while the consumers experience serious health issues (Pruteanu et al 2022).…”

Heavy metal pollutants i.e. lead and nickel are introduced to cultivable land through many sources and get accumulated in the soil profiles and contaminate water bodies which affect the growth and production of several crops. Seaweeds are rich in nutrients and have the ability to improve soil fertility by adding nutrients and organic contents to soil. In this study, S. ilicifolium was used with and without plant growth promoting rhizobacteria (PGPR) P. aeruginosa which showed heavy metal biodegradation capacity of 99.06% for lead and 98.8% for nickel against said metal stress. The individual and combined treatment of Sargassum ilicifolium as soil amendment and P. aeruginosa improved sunflower growth under 0.5 mM lead (Pb) and nickel (Ni) contaminations. The morphological characteristics of plants including shoot and root length and fresh weight were improved under stress and non-stressed condition. The biochemical analysis of proline, total phenols, peroxidase (POD), superoxide dismutase (SOD) and DPPH-radical scavenging activity also indicated that plant tolerance was improved under heavy metal stress.

“…Heavy metal pollution not only degrades the quality of the soil, crops, atmosphere, and water bodies, but also threatens human health through the food chain [7][8][9]. Soils are important sinks for heavy metals discharged into the environment [10][11][12]. Therefore, heavy metal pollution in soils has become a serious issue that has attracted much attention worldwide [13][14][15].…”

With the development of the economy and society, the environmental problems caused by heavy metals have always been the focus of attention. Strong concern has been recently shown for the heavy metal pollution of soils in southwestern China. The heavy metals of surface soils in the Xinping area of Yunnan province, China are surveyed along with some crop samples. There are 3312 surface soils and 95 crop samples collected in about 370 square kilometers. Heavy metals including As, Cd, Cr, Hg, and Pb and pH are analyzed. New single and integrated pollution indices of heavy metals for soils (PI and PIn) and crops (PIc and PInc) based on Chinese criteria (GB15618-2018 and GB2762-2022) are described and presented here and used to assess the pollution status of heavy metals. The results indicate that the background level of surface soils is about 62.1%, the screening level is about 33.4%, and the intervention level is about 4.5%, which is mainly a result from Cr and spatially coincides with the peridotite rock, indicating a geogenic pollution source. Most crop samples are not contaminated with heavy metals. Comparing the results of the two integrated pollution indices between soils and crops, two inconsistent assessments are observed. One is that some contaminated crops are growing in unpolluted areas (or Type I) and the other is that some uncontaminated crops are growing in polluted areas (or Type II). This indicates a new challenge between the assessment criteria on soils and crops.
