“…At present, due to an increase in anthropogenic activities, there is a disproportionate increase in the concentration of risk elements in the environment (Morais et al, 2012;Ying et al, 2018). Such a highly toxic element is ubiquitous cadmium (Cd) (Liu et al, 2016;Shi-Wei et al, 2016;Peng et al, 2017). This work is focused on toxic Cd, which belongs to the element with a high risk potential for soil, plants and human health (Meharg et al, 2013;Das et al, 2014;Shi-Wei et al, 2016;Borgulat et al, 2018) and is focused on remediation medium -garden compost, which is usable in agricultural practices and has the potential to reduce the availability of toxic elements to the environment.…”

Soil is a sensitive ecological factor. Biodegradable materials from the environment can also be used to deal with serious ecological problems. Soil affecting by remediation medium - garden compost - was analysed for toxic cadmium (Cd) in terms of environmental protection. The objective of this research was to analyse soil and compost at foothill locality of the Tribeč Mountains (Southwestern Slovakia) in the years 2015−2017 to determine Cd contents in soil and compost, pH and to assess Cd bioavailability. The analyses were carried out using the Atomic Absorption Spectrometry with seven-step Selective Sequential Extraction methods. The results obtained were evaluated statistically using the SAS 9.4 software method by Spearman’s correlation coefficient. The results showed that Cd contents in soil had reached 2.96 mg kg−1 and soil with compost (the ratio 1:1) 2.71 mg kg−1 dry matter. Cd contents in the soil exceeded maximum allowed limit of 196%. And deceased by 25% after adding compost. The pH in soil with compost varied from 6.78 to 7.98. The pH prevented the mobility of Cd about 8.3% in average. Statistical dependence was high, which was demonstrated for relationship between Cd in soil, pH and compost. Available Cd forms in soil were 53.3% and soil with compost were 45% in average. The garden compost as a remediation medium reduced Cd bioavailability.

“…Cadmium and lead are among the most frequently analyzed heavy metals due to their toxicity [15][16], but there is no information about the amount of these elements that can be absorbed into the human body. For this reason, analyses of the content of lead and cadmium ions in mushroom material after digestion in the artifi cial digestive juices (60 minutes for artifi cial gastric juice and 150 minutes for artifi cial intestinal juice) under conditions simulating the human intestinal tract were performed Data are presented as the mean ±SD (standard deviation); n = 3 repetitions.…”

“…Their use has shown high rates of heavy metal removal of 85% -95% for iron, copper, zinc, cadmium, arsenic and chrome with plants of tested species such as Eichhornia crassipes, Pistia stratiotes, Lemna minor, Echinochloa crusgalli, among other macrophytes (Pereira et al, 2011;Martelo and Lara Borrero, 2012;Silva et al, 2013). Peng et al (2017) cite that E. crusgalli has potential for phytoremediation of Cd in soils, but there is no data for water or how much time is required to perform the phytoremediation process.…”

Phytoremediation has been used as an alternative for removal of heavy metals in aquatic environments, but plant residence time and toxicity reduction need to be studied. Ecotoxicological bioassays and root anatomic studies were conducted in order to validate the phytoremediation of Echinochloa crus-galli L. at three different ages. The experiment was conducted using E. crus-galli seeds with processing factorial experimental design (2x3) and four replicates. Cadmium presence and absence (0.8 and 0 mg L-1) at three times (20, 30, and 45 days after germination). Cd levels were quantified by flame atomic absorption spectroscopy on both aerial parts and roots. A bioassay was performed testing both acute and chronic effects using microcrustacean Daphnia similis with the purpose of evaluating phytoremediation efficiency. Regardless of biomass, E. crus-galli L. can be used for 16 to 19 days for 45 days after germination (DAG), tolerating the phytotoxicity of this metal. The residual solution after phytoremediation had chronic effect on D. similis, indicating that the time taken was not sufficient to reduce the toxicity of the solution. Thus, ecotoxicological essays are important tools in evaluating the efficiency of this type of process. While E. crus-galli L. is a valuable tool in Cd phytoremediation programs, exposure time must be higher than 19 days to reduce concentrations of this metal in the water to conform to the CONAMA 357/2005 e 430/2011 standards.
