“…However, the BR11 MRV showed below detectable presence of Pb, Cd, Cr, Co and Ni. Furthermore, none of the observed levels of PTEs that were detected exceeded the corresponding maximum allowable concentrations (mg kg -1 ; Fe, 45; Mn, 500; Zn, 40; and Cu, 10) [31]. The PCA was used to explore the origins of PTEs in the sampled BR11 rice cultivar (Fig.…”

Rice contributes significantly to both food security and livelihoods in Bangladesh. Despite challenges such as an immense population growth rate and decreased arable land since gaining independence, Bangladesh has attained self-sufficiency in rice production by adopting modern rice varieties (MRVs). However, not all introduced MRVs have gained widespread acceptance among farmers due to concerns about productivity and profitability. Notably, BR11, an MRV, stands out as a prominently adopted rice cultivar during the Aman rice-growing season. This study aims to assess the levels of essential nutrient minerals (Na, K, Ca and Mg) and potentially toxic elements (PTEs) (Cd, Cu, Pb, Ni, Co, Fe, Mn, Zn, Cr) in the BR11 rice cultivar and also to evaluate associated health risks. The concentrations of Na, K, Ca and Mg (mg 100 g–1) in the sampled BR11 rice cultivar were found to be 4.4 ± 2.4, 108.5 ± 24.9, 3.4 ± 0.4 and 4.5 ± 1.1, respectively. Among the PTEs, Cd, Pb, Ni, Co, or Cr contents were below the detection limit, while Fe, Mn, Zn and Cu contents (mg kg–1) were 12.0 ± 4.0, 9.2 ± 1.5, 18.7 ± 2.7 and 2.9 ± 1.0. Comparisons of PTE contents in BR11 rice cultivars exposed to industrial activities with those cultivated in non-industrial zones did not reveal any statistically significant variations (p < 0.05). The estimated daily intake of nutrient minerals through the consumption of BR11 rice was significantly below the daily recommended dietary reference intakes. Likewise, the accumulation of PTEs in the BR11 rice cultivar was well below the maximum allowable concentrations recommended by WHO or FAO. Health risk assessments, involving the computation of non-carcinogenic and carcinogenic risks, did not indicate any concerning risk scenarios associated with the consumption of the BR11 rice cultivar. The data suggests that BR11 is a safe MRV for daily consumption, affirming its suitability for inclusion in the daily diet.

“…For instance, the presence of organic matter reduces the bioavailability of metals due to the surface complexation (Prokop et al, 2003;Qi et al, 2020), or its bioavailability may increase due to competitive binding with Ca and Mg ions (Allen & Janssen, 2006). Ecological risk assessment of metals in paddy soil rice areas in Pakistan demonstrated that Cd has the highest risk based on both its total environmental concentration and bioavailable concentration (Natasha et al, 2022). A source-specific ecological risk assessment revealed that Cd is critical in terms of bioaccumulation in wheat and maize cultivated areas caused by mining activities, sewage irrigation, industrial activities, or agricultural processes (Zhuang et al, 2023).…”

Plastics smaller than 5 mm that end up in a soil environment are known as microplastics (MPs). Microplastics have become a common contaminant in agricultural areas in addition to metals. However, the effect of cadmium (Cd) on soil organisms has not been clearly defined in the presence of MPs. In addition to MPs, biosolid application as a soil amendment in agricultural lands is also leading to shifts in soil conditions, such as the concentrations of nutrients and organic matter. Therefore, the aim of this study is to investigate the toxicity and bioaccumulation of Cd for Enchytraeus crypticus in the presence of polystyrene (PS)-MPs and biosolids to provide insight into their possible interactions. The lethal toxic concentration (LC50) for Cd was higher than 650 mg Cd/kg dry soil for all conditions. The presence of PS-MPs increased the toxicity of Cd for which EC50 was 102 and 38 mg Cd/kg dry soil without and with Cd, respectively, which may be the result of an increased exposure rate through adsorption of Cd on PS-MPs. On the contrary, the presence of biosolids decreased the toxicity of Cd where EC50 was 193 and 473 mg Cd/kg dry soil for the sets applied with 0.6 and 0.9 g biosolids, respectively. Coexistence of biosolids and PS-MPs decreased the reproduction toxicity of Cd, which is similar to the biosolid effect (EC50 is 305 mg Cd/kg dry soil). Bioaccumulation of Cd only positively correlated with its initial concentration in soil and was not affected by the presence of PS-MPs or biosolids.
