“…Although Zn in the food basket is recommended to increase body growth, according to the study by Zhang et al, exposure to the metal upsets the balance of cholesterol and fertility. 27,28 Zn and copper have also been reported to lead dysfunction of the central nervous, respiratory, and endocrine systems. 29 Research has shown that increasing in the concentration of lead in the body also has detrimental effects on the central nervous system and blood enzymes.…”

Background: One of the concerns faced by many countries, especially developing countries, is the presence of heavy metals in water, air and food, which directly and indirectly cause adverse effects on human health through inhalation and ingestion. Rudbar city is suitable for growing olives due to its climatic conditions, and most of the people living in the area use this product in their meals. The purpose of this study was to determine the amount of heavy metals manganese, iron, copper, zinc (Zn), lead and cadmium in the olives of this area. Methods: For this purpose, 13 olive samples were selected and their heavy metal concentration was measured by ICP-OES device. Results: The results indicated that the concentrations of cadmium, lead, manganese, iron, Zn and copper in the samples of Guilan olives were 0.056±0.019, 0.564±0.170, 2.017±0.211, 7.577±1.312, 1.846±0.387 and 4.147±0.901, respectively. Also, in the imported samples it was 0.065±0.014, 0.494±0.153, 1.295±0.353, 3.465±1.066, 1.357. 0.412 and 4.103±1.335, respectively. Conclusion: Except for one, the amount of lead in all Iranian samples was less than the allowable level. It was also observed that except for lead, the concentration of all metals in foreign samples was lower than Iranian samples. Since olives are one of the most popular food items in the area and considered by travelers, continuous monitoring of the heavy metals in this food is essential.

“…Kabiri et al ( 2022 ) conducted diverse leaching test methods to explore PFASs leaching behaviour from soil. Additionally, leaching tests were employed by Guleria and Chakma ( 2019 ) for human health risk assessment, specifically evaluating heavy metals leaching to assess potential risks via dermal contact. Notably, all the mentioned studies in the literature employed leaching tests based on a simulation approach.…”

The concept of circular economy, aiming at increasing the sustainability of products and services in the water and other sectors, is gaining momentum worldwide. Driven by this concept, novel bio-composite materials produced by recovering resources from different parts of the water cycle are now manufactured in The Netherlands. The new materials are used for different products such as canal bank protection elements, as an alternative to similar elements made of hardwood. As much as these new materials are appealing from the sustainability point of view, they may leach toxic substances into the aquatic environment given some of their ingredients, e.g., cellulose recovered from wastewater treatment. Therefore, a methodology for the assessment of related environmental risks is needed and it does not exist currently. This paper addresses this knowledge gap by presenting a framework for this. The framework is based on European environmental risk assessment guidelines, and it includes four key steps: (i) hazard identification, (ii) dose–response modelling, (iii) exposure assessment and (iv) risk characterisation (i.e. assessment). As part of the first step, laboratory leaching tests were carried out to evaluate the potential release of specific chemical substances such as heavy metals and resin compounds into the aquatic environment. Laboratory test results were then used as input data to evaluate the risk of potential leaching from canal bank protection elements into surface water. A deterministic model was used first to identify the chemicals exceeding the guideline threshold. Subsequently, a stochastic model was applied to evaluate the environmental risks across a range of leachate concentrations and water velocities in the canal, thereby simulating a broader spectrum of possible situations. The risk analyses were conducted for four alternative bio-composite materials made of different ingredients, two different flow conditions (stagnant water and advective flow) in two types of canals (wide ditch and primary watercourse) and for two different water levels based on season conditions (summer and winter conditions). The results obtained from leaching tests identified Cu, Mn, Zn, styrene and furfuryl alcohol as potentially troublesome chemicals. In the case of stagnant water, the absence of a flow rate increases the residence time of the chemicals in the surface water, resulting in a higher PEC/PNEC (i.e. risk) value. However, under stagnant case conditions, environmental risks for all chemicals considered turned out to be below the safety threshold. In the advective case, the existence of a flow rate, even at low velocities simulating the conditions of ‘almost no flow,’ contributes to increased dilution, resulting in lower PEC/PNEC ratio values. The results presented here, even though representing real-case scenarios, are only indicative as these are based on laboratory leaching tests and a number of assumptions made. Additional field tests involving collecting and analysing water and sediment samples from the canal where the canal bank protection elements are located, over a prolonged period, are required to come up with more conclusive findings.

“…However, in many countries, this industrial by-product has not been appropriately utilized rather it has been ignored and dumped like a leftover substance. As a consequence, it poses a significant threat to the soil environment, streams as well as groundwater [3,4] and becomes a noxious source of health hazards for humans and animals when reached to the domestic areas [5,6]. Furthermore, the dumping sites do not support sound plant growth because of its nutritional deficiency (generally N and P), low microbial activity, high salt concentration along enhanced heavy metal loads [7,8].…”

Assessing the Capability of Chemical Ameliorants to Reduce the Bioavailability of Heavy Metals in Bulk Fly Ash Contaminated Soil

et al. 2021

In-situ rehabilitation of fly ash at dumping sites has rarely been addressed for crop production due to growth-related constraints, largely of heavy metal (HM) contamination in soils and crops. Current communication deals with a novel approach to identify a suitable management option for rejuvenating the contaminated soils. In this background, a 60-days incubation experiment was conducted with different fly ash-soil mixtures (50 + 50%, A1; 75 + 25%, A2; 100 + 0%, A3) along with four ameliorants, namely, lime (T1), sodium sulphide (T2), di-ammonium phosphate (T3), and humic acid (T4) at 30 ± 2 °C to assess the ability of different fly ash-soil-ameliorant mixtures in reducing bio-availability of HMs. Diethylenetriaminepentaacetic acid (DTPA)-extractable bio-available HM contents for lead (Pb), cadmium (Cd), nickel (Ni), and chromium (Cr) and their respective ratios to total HM contents under the influence of different treatments were estimated at 0, 15, 30, 45, and 60 days of incubation. Further, the eco-toxicological impact of different treatments on soil microbial properties was studied after 60 days of experimentation. A1T1 significantly recorded the lowest bio-availability of HMs (~49–233% lower) followed by A2T1 (~35–133%) among the treatments. The principal component analysis also confirmed the superiority of A1T1 and A2T1 in this regard. Further, A1T1 achieved low contamination factor and ecological risk with substantial microbial biomass carbon load and dehydrogenase activity. Thus, liming to fly ash-soil mixture at 50:50 may be considered as the best management option for ameliorating metal toxicity. This technology may guide thermal power plants to provide the necessary package of practices for the stakeholders to revive their contaminated lands for better environmental sustainability.
