“…Poluarea cu metale grele cum ar fi Cd, Pb, Cu, Zn și Sn, afectează ecosistemele forestiere, fiind identificate concentrații ale acestor elemente atât în sol cât și în plante (Mihali et al, 2013). În ceea ce privește arborii de rășinoase din țara noastră primele semne ale declinului arborilor de brad și molid au fost semnalate încă din anul 1967, în jurul Fabricii de Ciment Bicaz (Giurgiu, 1967).…”

Creșterea radială a arborilor variază de la un sezon de vegetație la altul, datorită variației factorilor de mediu de la un an la altul. Poluarea aerului poate modifica comportamentul normal al creșterii arborilor atât în ceea ce privește dinamica creșterii, cât și răspunsul la schimbările de mediu. Schimbările climatice și poluarea aerului sunt strâns corelate deși de cele mai multe ori impactul poluării asupra creșterii arborilor și relația dintre climat și creșterea radială a arborilor au fost analizate separat. Acest studiu prezintă rezultatele privind influența poluării industriale asupra relației dintre creșterea arborilor și factorii climatici. Au fost studiate două specii de arbori, molid (Picea abies L.) și brad (Abies alba L.), din zona Tarnița, județul Suceava, zonă intens poluată de activitatea minieră și prelucrarea metalelor neferoase. Suprafețele experimentale au fost amplasate la diferite distanțe față de sursa de poluare pentru a putea surprinde arbori afectați în diferite grade de poluarea industrială locală (intens poluat, moderat poluat și nepoluat). Analiza răspunsului arborilor la variația factorilor climatici a scos în evidență faptul că precipitațiile ridicate din anumite luni pot influența pozitiv creșterile arborilor din zonele poluate. Temperaturile ridicate din sezonul de vegetație pot influența negativ arborii de rășinoase, iar răspunsul este mai puternic în cazul arborilor din zonele afectate de poluare. Perioada în care arborii de rășinoase din zona Tarnița, au răspuns diferit în raport cu gradul de afectare al poluării se suprapune perfect cu perioada în care activitatea minieră din acea zonă se desfășura la un nivel foarte ridicat.

“…To the best of our knowledge, there is little research developed in Romania in this field and no research has considered the rapeseed plant. For example, Damian et al [56] used the Sinapis alba L. (white mustard) plant as a bioindicator to revegetate the metal-polluted soil from the metallurgical plant Romplumb Baia Mare, Romania. Stancu [57] tested different plants (Rumex acetosella, Rubus caesius, Crataegus monogyna, Betula pendula and Agrostis capillaris) in her PhD thesis to remediate a contaminated area from the Metaliferi Mountains, which are known as the main gold production center in Romania, with great significance in mining.…”

The potential of the model crop Brassica napus L. (rapeseed) for the phytoremediation of soils polluted with metals was investigated at laboratory scale. The first step consists in the evaluation of the seed germination and growth of the Brassica napus L. plant in a controlled environment, followed by the determination of the photosynthetic pigments content represented by chlorophyll a and b and carotenoids. The degree of metal accumulation in rapeseed has been evaluated by the bioaccumulation factor (BAC), the bioconcentration factor (BCF) and the translocation factor (TF). Phytotoxicity tests were performed in Petri dishes with filter papers moistened with metal solutions in the range of 0 to 300 mg/L Pb(II) or Cd(II). At the highest concentration of the lead and cadmium treatments (300 mg/L), B. napus L. showed the lowest germination degree (56.67% and 43.33%, respectively). According to Tukey test results, Pb(II) concentrations of up to 300 mg/L do not significantly affect the length of the hypocotyls, whereas, in the case of Cd(II), the mean of the radicle and hypocotyl lengths of the seedlings are significantly affected compared to the mean of the control. In soil pot experiments, important changes have been obtained in the pigment content, especially in the case of cadmium. For both metals and for each treatment (100 to 1500 mg/kg Pb(II) and 1 to 30 mg/kg Cd(II)), a TF < 1 indicates an ineffective metal transfer from root to shoot. Finally, rapeseed can be considered a tolerant plant and a suitable candidate for Pb(II) and Cd(II) accumulation and for the phytostabilization of contaminated soil under the experimental conditions adopted in the present study.

“…Each of these components has shown a positive effect on reducing the content of some PTEs, e.g., perlite: Pb, Cu, Ni, Cd, [38]; chicken manure: Cd, Ni [39,40]; CaCO 3 : Pb, Cu, Cd [41,42]. Zeolites have a positive effect on the fertility and sorption properties of the soil and the formation of phytomass [43,44]. Acting as a free soluble fertilizer, they improve the water balance and sorption properties, especially in light, sandy soils, which translates into higher yield and better quality.…”

Effect of Sorbent Additives to Copper-Contaminated Soils on Seed Germination and Early Growth of Grass Seedlings

et al. 2021

Heavy metal and metalloid-contaminated soil is a serious barrier to colonization for many plant species. The problem of the elimination of toxic waste accumulated in technogenous soils in many highly transformed regions is extremely important. Hence, another attempt was made to analyze the effect of the addition of sorbents (BCH—biochar, B—bentonite, ChM—chicken manure, OS—organo-zeolitic substrate) to contaminated copper soil on the germination and early growth of Eurasian common grass species (Agrostis capillaris, A. stolonifera, Festuca rubra and Poa pratensis), which could potentially be used in recultivation. This experiment was based on the laboratory sandwich method. Standard germination indexes, morphometry and biomass analysis were used. The percentage of germinating seeds was lower in each of the soil variants and sorbents used compared to the control. Dry mass was positively stimulated by all sorbents. The response to the addition of sorbents, expressed as the electrolyte leakage of seedlings, was different depending on the species and type of sorbent. Among all sorbents, the most positive effects on germination and growth were observed in the case of OS. Overall, the response to the addition of sorbents was different in the studied species, depending on their stage of development.
