“…Large quantities of industrial effluents and sewage sludge are potential sources of metal contamination in water and soil environments due to their direct discharge into surface water bodies [7]. As a result, vegetables grown with wastewater irrigation accumulate metals from the polluted soil and water, thus exceeding safe limits [8,9]. The use of effluents/wastewater over a long period of time to grow vegetables results in the uptake of toxic metals by crops with a possibility of their excess in the food chain.…”

The present study assessed the accumulation and distribution of metals in tomato (Lycopersicon esculentum L.) fruits grown with wastewater. The concentrations of nine metals (Co, Cd, Mn, Cu, Ni, Fe, Zn, and Pb) were analyzed in wastewater collected from the study site. Four metals with substantially higher concentrations in wastewater, namely Fe, Zn, Mn, and Pb, were selected for further analysis in soil, plant organs, and parts of tomato fruits. In addition, the concentrations of essential nutrients (Na, K, Ca, P, and N) in all samples were also analyzed. Concentrations of Zn (0.77 mg L−1) and Pb (0.44 mg L−1) were found to be the maximum, and Mn concentration was the minimum (0.16 mg L−1) in wastewater samples. However, in soil samples, the concentrations of Fe (35.88 mg kg−1) and Pb (29.62 mg kg−1) were the highest, which ultimately led to their higher accumulation in plant tissues. When metal accumulation in the whole plant and tomato fruit was compared with the WHO permissible limits, the accumulated concentrations of Zn (16.35, 12.98, and 23.85 mg kg−1 d.wt. in peri-, endo-, and mesocarp, respectively), Mn (7.08, 7.75, and 4.6 mg kg−1 d.wt. in peri-, endo-, and mesocarp, respectively), and Pb (30.05, 29.42, and 34.95 mg kg−1 d.wt. in peri-, endo-, and mesocarp, respectively) exceeded the safe limits except for Fe (13.6, 32.3, and 63.43 mg kg−1 d.wt. in peri-, endo-, and mesocarp, respectively). Thus, the irrigation of tomato fruits with wastewater can cause health risks to humans under prolonged consumption, and the regular monitoring of metals is necessary to reduce the health risks from human consumption.

“…Determinations of nutrient and heavy metal content were made between February-March 2017; September-October 2017; February-March 2018; August-September 2018. Sludge and soil samples were taken observing the regulations in force [39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55]. The sludge samples were taken before entering the digester (sets 1-4, undigested sludge) and after the anaerobic digestion (sets 5-8, digested sludge).…”

The use of sewage sludge in agriculture decreases the pressure on landfills. In Romania, massive investments have been made in wastewater treatment stations, which have resulted in the accumulation of important quantities of sewage sludge. The presence of these sewage sludges coincides with large areas of degraded agricultural land. The aim of the present article is to identify the best technological combinations meant to solve these problems simultaneously. Adapting the quality and parameters of the sludge to the specificity of the land solves the possible compatibility problems, thus reducing the impact on the environment. The physico-chemical characteristics of the fermented sludge were monitored and optimal solutions for their treatment were suggested so as to allow that the sludge could be used in agriculture according to the characteristics of the soils. The content of heavy metals in the sewage sludge was closely monitored because the use of sewage sludge as a fertilizer does not allow for any increases in the concentrations of these in soils. The article identifies those agricultural areas which are suitable for the use of sludge, as well as ways of correcting some parameters (e.g., pH), which allow the improvement of soil quality and obtained higher agricultural production.

It is well known the role of nutrients in growing crops and obtaining cost-effective production, but also to ensure a nutritious contribution to humans and animals alike, in food safety conditions. This study aims to evaluate both the supply of nutrients and the main parameters of agricultural soils, in 0-30 cm layer, under intensive agricultural practices pressure, undertaken in an agricultural area influenced by steel industry activities. The soil samples were collected from three sites and different plots grown with wheat, corn, and sunflower, and subjected to analysis protocols within Galati County Soil Survey Office. Soil supply with the main macronutrients indicates imbalances in all studied sites, regardless of the cultivated plants. Overall, soils have a high nitrogen deficiency, correlated with the low level of soil organic matter supply. Total Kjeldahl nitrogen values are between 0.076-0.258 % for all surveyed plots. Mobile phosphorus is low to very high (8-276 ppm), while mobile potassium is low to very high (70-600 ppm). On the one hand, this is due to the natural process of soil degradation through water and wind erosion, and on the other to anthropogenic activities. Most of the time, out of the desire to obtain large harvests, farmers apply non-compliant amounts of fertilizers, which translates into the physical and chemical degradation of agricultural soils and poor management of crop nutrition. Other investigated soil parameters were pH, particle size fractions, as they are related to the dynamics of chemical elements in the soil. It could be concluded that the studied agricultural soils are characterized by imbalances in terms of providing chemical elements accessible to plants, in relation to the main investigated physico-chemical parameters and environmental conditions.
