“…Cantareus aspersus (syn. Helix aspersa) was used as study system in this present work because it is the most often used terrestrial gastropod in environmental toxicology; it has a well-known biology [9] and is easily reared under laboratory conditions [10].…”

Cadmium is very hazardous pollutant with massive impact on aspects of everyday life. Little knowledge exists on kinetics of dietary cadmium retention in Cantareus aspersus for durations above three months although this species of land snails serves as excellent ecotoxicological model for studying cadmium hazard. Here was used a continuous 112-day exposure study design, in which test snails were exposed to a wide range of dietary cadmium levels, including human- and environmentally-relevant levels. Using Flame Atomic Absorption Spectrometry, cadmium levels in the hepatopancreas were found to increase significantly, and in dose-dependent manner starting from a dietary cadmium dose of 0.2 mg/kg dry weight. The results of the present study render the hepatopancreas of mature snails, C. aspersus, as excellent endpoints for assessing Cd toxicity over a broad range of concentrations. Hence, this species of land snails can be reliably used for both active and passive biomonitoring of environmental cadmium pollution.

Surface soil samples were collected near the Open Pit Bor (S1) and Open Pit Cerovo (S2), a grassland along the Borska Reka River (S3) and an unpolluted garden near Slatina village (reference site). Spontaneous plants (dandelion, nettle, coltsfoot, and creeping buttercup) and vegetables (onion, garlic, carrot, parsley, celery, potatoes, dill, and sorrel) were obtained from the former three sites and the reference site, respectively. The samples were analyzed for Zn, Cu, Fe, Mn, and Pb via FAAS. Pollution indices indicated low-to-moderate soil contamination at sites S1, S2, and S3. Cu was the main contaminant of environmental concern, being above the maximum admitted concentration at site S1. Metal levels in spontaneous plants were below phytotoxic levels. Cu content of leafy vegetables and celery roots and Pb content of most vegetables were not safe for human consumption. Metal concentrations tended to be significantly lower in plants than in soils, with only Cu occurring at significantly elevated levels in celery roots and sorrel leaves. Non-carcinogenic risk assessment showed that consumption of carrot roots and especially celery roots grown on unpolluted soils from the Bor area might pose long-term health risks for females and males, with the main contributors being Cu and Fe.

“…The lowest concentration of Zn and Cu was found in the analysed sample of Brassica oleracea, and the highest Zn content was recorded in Spinacia oleracea, while the highest Cu content was verified in Urtica dioica. The Cu content in the analysed Urtica dioica leaves is three times higher than the content published by Nica et al (2013). The accumulation of copper in soils and plants is mainly due to anthropogenic origins, such as mining or industrial activities.…”

Leafy plants and vegetables, which are grown and consumed on almost every continent, are vital to the human diet. It is well known that these plants mainly provide trace elements, vitamins, minerals, and fibres (Mateos-Maces et al. 2020, Sarkar et al. 2022. In addition to the nutritional benefits of leafy plants, most of them accumulate higher amounts of heavy metals because they absorb metals in their edible parts (Saleem et al. 2020).Heavy metal accumulation in plants depends on soil and metal types, soil conditions, plant species, growth stages, weather, and environmental factors (Zhang et al. 2020). Leafy plants grown in contaminated soils have a greater chance of accumulating heavy metals than plants grown in uncontaminated soil (Proshad et al. 2020). Anthropogenic activities such as industrial processing and mining are the primary causes of environmental heavy metal pollution. Furthermore, the widespread use of agrochemicals such as metal-based pesticides and fertilisers contributes significantly to the contamination of various plants and vegetables (Briffa et al. 2020, Aloud et al. 2022. Therefore, several studies are directed toward examining heavy metals in leafy plants and their impact on human health. According to numerous toxicological studies, daily consumption of heavy metal-polluted leafy plants can have an adverse effect on the food chain and may have a negative impact on human health, including anaemia, hypertension, cardiovascular diseases, metabolic problems, psychological disor-
