“…Although Pb is a polluted metal in the global environment that has attracted special attention in recent decades [ 45 , 46 , 47 ], in all five lakes it is unpolluted and has very low ecological risks. This is likely due to the fact that these lakes are relatively remote and receive few anthropogenic Pb emissions derived mainly from urban/industrial areas.…”

Background soils are frequently utilized as a surrogate to assess pollution levels and environmental risks of heavy metals in Chinese lakes. However, there remains a lack of understanding regarding the reliability and uncertainty of such assessments. Here, we determined heavy metals (As, Cd, Co, Cr, Cu, Hg, Ni, Pb, and Zn) in sediment cores from five rural lakes in North China to evaluate the reliability and uncertainty of the assessments using background soils by comparing them with assessments based on background sediments. Comparative studies reveal large uncertainties in the assessments using background soils. Among these metals, uncertainties for Hg and Cd are relatively large, whereas those for the other metals are minor. This discrepancy is due to the considerably higher natural variability of Hg and Cd in soils and sediments in comparison to the other metals. Generally, assessments utilizing background soils underestimate pollution levels and risks of Hg but overestimate those of Cd in these lakes. Despite limited human activities around the lakes, they still received a considerable influx of heavy metals via regional atmospheric transport. Assessments of the nine metals indicate moderate to considerable ecological risks in these lakes. The risks are contributed primarily (78–89%) by Hg and Cd. This study underscores the substantial uncertainties in assessing heavy metal pollution and risks using regional background soils and emphasizes the importance of controlling atmospheric emissions of Hg and Cd to mitigate pollution in rural and remote water bodies in China.

“…Specifically, Amaranthus hybridus and Corchorus olitorius (commonly known as amaranth and jute mallow, respectively) are highly important vegetables in some parts of Nigeria due to their nutritious leaves, succulent stems, and cereal-like grains (Opega et al, 2016;Ogwu, 2020). However, the production of these nutritious vegetables in peri-urban sites poses contamination risks from various sources such as industrial pollution and transportation emissions (Anifowose et al, 2022;Agyeman et al, 2023;Onwuka et al, 2023).…”

This study analyzed heavy metal contamination in commonly consumed leafy vegetables grown on peri-urban farms in Osogbo and Ilorin, Nigeria. Across five neighborhoods in each city, fresh vegetable samples were collected and assessed for lead (Pb), copper (Cu), zinc (Zn), iron (Fe), and manganese (Mn) using atomic absorption spectrophotometry. Alarming Pb levels were discovered, with mean concentrations ranging from 0.01 to 0.26 mg/kg depending on the sampling site, up to 4 times above the WHO safety limit (0.05 mg/kg). Average Cu levels also exceeded guidelines at 0.17 mg/kg in Osogbo and 0.13 mg/kg in Ilorin. Likewise, average Fe surpassed recommended thresholds at 0.54 mg/kg and 0.52 mg/kg in the two cities, respectively. Chronic dietary exposure to these metals poses risks of lung, kidney, neurological and other organ damage among consumers. The contamination likely results from industrial emissions and vehicular pollution. Further research should identify specific entry points across the food production pipeline to guide targeted interventions. Additionally, alternative cultivation methods and consumer health advisories are needed to reduce toxicant exposures from urban-grown greens that many Nigerians rely on. Urgent multi-sectoral action must decrease heavy metal accumulation in vegetables from farms encircled by expanding cities.
