“…The median values of Cu and Pb in all examined samples were higher only than the EPA (P,A,M). The decrease in plants' chlorophyll content is one of the crucial symptoms of Pb toxicity [58]. According to Jin et al [59] P toxicity stimulates the growth of lung tumors in mammalian species.…”

The purpose of this study is the evaluation of fire effect on contaminated land and the assessment of the associated risk of human health and terrestrial ecological receptors. Ash and soil samples were gathered from burned and unburned areas (central Evia, Greece) which are adjacent with a Natura 2000 area. The geochemical dataset includes 20 sampling sites and 35 elements. The wildfire severity was investigated by applying a macroscopic approach and field observations. Statistical and spatial analysis were applied for delineating the distribution of elements in ash and soil. Elemental balance approach was performed for estimating net gain (+) or loss (−) to the ash. Element contents in sampling sites were compared to screening values proposed by the literature. Hundreds of hectares of burned land including wildland areas in central Evia are contaminated with (contents in mg Kg−1), Co (up to 43.5), Cr (up to 244), Mn (up to 1158), Ni (up to 463) associated with geogenic sources such as serpentinite peridotites and Ni-laterite deposits. Aluminum, As, Cd, Co, Cr, Fe, Mn, Ni, Pb, V and Zn contents recorded in the sampling sites are posing a potential risk to human health and ecological receptors.

“…All the FA-treated AMDirrigated potatoes had significantly higher Cu levels compared to the control (Figure 3). The CODEX general standard limits for food pollutants and toxins in food and feed (CODEX STAN 193-1995), which indicate a maximum 0.3 mg/kg for potato, were met by these heavy metal concentrations [70][71][72][73][74]. The WHO and FAO recommend that the concentration of Cu in food should not be above 30 mg/kg, while that of the NAFDAC is 20 mg/kg for food.…”

Accumulation of Heavy Metals, Yield and Nutritional Composition of Potato (Solanum tuberosum L.) Cultivars Irrigated with Fly-Ash-Treated Acid Mine Drainage

This study compared the responses of two potato cultivars, Fianna and Lady rosetta (both determinate and indeterminate), to irrigation with various fly ash: acid mine drainage (AMD) amelioration ratios in two separate seasons. In order to calculate crude protein (CP), the nutritional composition (NC) of potato tuber samples was examined using the combustion method. The results showed that the NC of plants irrigated with AMD mixed with fly ash was significantly affected differently at harvest. In plants exposed to 75% AMD irrigation, the mean moisture content of Lady rosetta was reduced by twice more compared to Fianna. Concisely, our study has demonstrated that irrigation with AMD mixed with fly ash can promote plant growth of potato cultivars and reduce their crude protein (CP) by approximately 4% when irrigated with both 50% FA: AMD and untreated AMD (100% AMD) ratio being applied; nonetheless, it was decreased by 1% when watered with 75% FA: AMD treatment, lipids content, carbohydrates, fresh tuber weight and dry tuber weight. On average, plants from both cultivars irrigated with the 75% AMD had higher fresh tuber weight (FTW), higher dry tuber weight (DTW) and carbohydrates compared to the controls. Furthermore, Lady rosetta cultivar exhibited higher carbohydrate and crude fiber compared to the control at 75 and 50% AMD treatments, respectively. Use of AMD in agriculture is likely to reduce its devastating environmental conditions and assist in irrigation of food crops, thereby alleviating both water and food shortages. Last, all the FA-AMD-treated potatoes had Pb concentrations that were below the minimum standard limits, and this proves that FA was able to adsorb the Pb ions in the tuber samples. Importantly, fly ash reduces a metal’s concentration in AMD. However, presence of heavy metals in such potatoes needs to be explored. It is also important to relate the possible metal intake relative to the standards by World Health Organization (WHO).

“…Some plant metabolic processes, including the synthesis of nitrogenous compounds, the metabolism of carbohydrates, and the absorption of water, are inhibited by lead. (Sharma, Dubey, 2005, Hamid et al 2010. In addition to altering soil microorganisms and their activities, which worsened soil fertility, pb contamination in soils also had a direct impact on changes in physiological indices, which further decreased yield.…”

Heavy metal like lead and chromium present in environment in large quantities cause a severe environmental concern. Significant risks to the environment and agriculture are posed by heavy metal contamination of the air, water, and soil as a result of increased urbanisation and industrialization. Heavy metal pollution in soils can harm nearby ecosystems, groundwater, agricultural productivity, and human health because of its persistence and high toxicity. Heavy metals are accumulated in the tissues of plants growing in metal-contaminated soil, which can have a negative impact on the morphology of the plant. The present study was carried out to determine the effect of different concentrations (50ml, 100ml, 150ml and 200ml) of chromium and lead on morphological attributes of three varieties (JS:335, JS:80-21, JS:75-46) of soybean (Glycine max). The result of the present study showed that the exposure of Glycine max to Pb and Cr resulted in a decrease in total length, number of nodes and number of leaves of a plant. The shape of leaves in case of treated plants was also changed from ovoid to heart and oval shapes, at higher concentration of heavy metals. Among the three different varieties (JS:335, JS:80-21, JS:75-46) of Glycine max (soybean) JS:335 showed maximum reduction and the JS:80-21 showed least reduction in the growth of a plant. Lead treatment proved more toxic than chromium treatment for all the three different varieties (JS:335, JS:80-21, JS:75-46) of Glycine max.
