“…This decline could be attributed to the high salt and heavy metal content in cement factory wastewater, which has been reported to negatively impact seed germination and seedling development. Ertekin et al [57] have also reported similar findings in sorghum irrigated with high amounts of heavy metal.…”

With increasing concerns over water scarcity, wastewater reclamation for agricultural irrigation has gained attention. However, the use of wastewater can have both positive and negative effects on crop growth. Seed germination and early seedling growth tests are considered to accurately represent crop growth population. This study aimed to evaluate the effect of different types and concentrations of wastewater on rice seed germination and early seedling growth. Two rice varieties, SIRAJ279 and MR219, were grown in wastewater from shrimp culture, domestic sources, and cement factories at five concentrations: 0 (control), 25, 50, 75, and 100%. Seed germination percentage and germination rate index were used to evaluate seed germination analysis, while the seedling length, seedling vigor index, seedling fresh weight, seedling dry weight, and phytotoxicity percentage were used to evaluate early seedling growth analysis. Results showed that the SIRAJ279 rice variety had overall better seed quality than MR219. Rice irrigated with shrimp culture and domestic wastewater showed better results in seed germination, germination rate index, seedling length, seedling vigor index, and seedling fresh weight than those irrigated with cement factory wastewater. However, no significant difference was observed in seedling dry weight. Additionally, increased wastewater concentration had a negative effect on seed and seedling results. Seedlings grown in wastewater with a concentration of 75-100% from cement factories had the highest phytotoxicity percentage (more than 30%). Therefore, it is recommended to dilute cement factory wastewater to 50% before using it for agricultural irrigation.

“…Elevated concentrations of Ni can significantly impact cell division in root meristems, altering root length [40]. Similarly, a root length decrease due to the presence of Ni was also reported for Phacelia tanacetifolia, Cucumis sativus, and Brassica nigra [46]; Sorghum bicolor [47]; and Salsola vermiculata [48].…”

The development of large-scale mining activity along the Central Andes of Argentina (CAA) has generated significant amounts of waste materials containing heavy metals. Phytoremediation is a promising eco-friendly, low-cost, and effective technology for the removal of heavy metals. The present study aimed to identify two native dominant species from the CCA, Adesmia subterranea and A. pinifolia, as metal-tolerant plant species for the first time, by evaluating the germination and early seedling growth at different concentrations (ppm) of Cd (3, 4.5 and 6), Ni (150, 225 and 300), As (20, 30 and 40), and Hg (0.8, 1.2 and 1.6) Early seedling growth was found to be more sensitive to heavy metals than germination. Ni and As exhibited the greatest inhibitory effect on both species’ germination percentages. In contrast, with Cd and Hg, no inhibitory effect was recorded. Root length, metal tolerance index, and fresh and dry weight were stimulated with Hg. However, the phytotoxic effect was greater as the concentration of Ni, As, and Cd increased. As an overall conclusion, the order of toxicity for these species can be classified as Ni > As > Cd > Hg. Therefore, Adesmia species could be considered as candidates for phytoremediation of soils contaminated with Hg and low concentrations of Cd.

Due to heavy metal contamination, there are currently significant losses in agriculture and food security. Anthropogenic sources led to increased heavy metal contamination, which was becoming an attentive problem for agriculture and food safety. Among these metals, lead (Pb), which is toxic and affects crop production, has emerged as a standout due to its severe toxicity and relatively obscure mode of action.This study aims to compare the chemical composition and nutritional value of three tested sorghum cultivars grown in Pb-spiked soil with different levels of Pb (0, 100, 200, 400 and 800 mg kg−1). Also, the impact of different Pb levels on germination, fresh and dry weight of underground and aboveground parts, and morphological characters of three tested sorghum cultivars were assessed. The results emphasized that the germination index (GRI), radical and plumule length (cm), vigor index (VI), and tolerance index (TI) declined significantly by increasing Pb levels at all the examined cultivars. The morphological parameters of the examined cultivars decreased progressively with increasing Pb concentration for three tested sorghum cultivars. The nutritive values and forage quality of examined cultivars are negatively impacted by higher Pb levels, rendering them hazardous to animal consumption. These results may help scheme a mitigation strategy for lead injuriousness.
