The aim of this study was to determine the concentrations of 11 metals in the soil of asbestos tailings in Stragari, Serbia, and in the selected plant species that grow on it, to determine the ability of the plant species in accumulation and tolerance of researched metals. Concentrations of elements researched in the soil had this order: Mg> Fe> Ca> Ni> Cr> Mn> Co> Zn> Pb> Cu> Cd. Concentrations of the metals in plants was variable, dependent on the plant species and types of metals, and graded in the order: Mg> Ca> Fe> Ni> Mn> Cr> Zn> Co> Pb> Cu> Cd. The concentrations of Ni and Cr in the investigated soil were above remediation values, as well as the maximum allowable concentration of substances in the soil according to regulation of Republic of Serbia, and the concentration of Cd and Co were above limit values for a given metals in the soil. The metal uptake does not necessarily correlate with metal content in the soil. Metal uptake by plants depends on the bioavailability of the metal in soils, which in turn depends on the retention time of the metal, as well as the interaction with other elements and substances. However, the most Mg, Fe, Mn, Pb, Cd, Co and Cr were found in species Sanguisorba minor, Ca and Cu in Eryngium serbicum, Ni in Alyssum murale, and Zn in Euphorbia cyparissias. In the Euphorbia cyparissias, it were determined the biological absorption coefficients greater than 1 for Zn and Cu, and in the species Eryngium serbicum and Sanguisorba minor greater than 2 for Cu. The results of this study emphasize the tolerance of several metal by species Sanguisorba minor, present the ability of Euphorbia cyparissias in accumulation of Zn and Cu, as well as of Eryngium serbicum and Sanguisorba minor in accumulation of Cu. Obtained results present the momentary picture of investigated locality, open a lot of questions connected with relationships soil/plant, contents of elements in both systems, their interactions and influences and represented the base for further research.

Negative Impacts

Eichhornia crassipes is well-known as water hyacinth. Water hyacinth grows rapidly in the nutrient-rich water and high light intensity places. The uncontrollable growth of water hyacinth has caused many negative impacts to the environment. For instance, interrupted water transport and decreased population of aquatic lives. The capacity of utilising water hyacinth is slower than water hyacinth growth and water hyacinth is still considered as a threat to theecosystem. This work was focused on the study of the pharmacological activity and heavy metal content of water hyacinth in Lake Cipondoh, Tangerang. Fresh water hyacinth was pre-treated through oven-drying and milling process. After that, each part of the plant was macerated by using multiple extraction method with 96% ethanol/water and three variations of sample-to-solvent ratios (1:30, 1:50, and 1:75 w/v). The result of the experiment showed thatwater hyacinth leaves produced an extract with lowest IC 50 (55.76 ± 6.73 ppm) compared toother parts. The most optimum solvent used to achieve this result was 96% ethanol/water (1:1 v/v). In order to obtain the lowest antioxidant activity, the sample to solvent ratio used was 1:50 and the heavy metal in the extract was very low. With this result, it was concluded that there is a promising opportunity to apply the water hyacinth growing in Lake Cipondoh, Tangerang as herbal medicine ingredient. Through this utilization, the overall number of water hyacinth in Indonesia can be reduced or at the least be controlled, so that the environmental problem caused by this plant can be minimized.

One of the solutions to fulfill  the food sustainability is diversification of local food. One of the local food that potential to be used and processed is bamboo shoots. In South Kalimantan, the potential of bamboo as a producer of bamboo shoot plants with an estimated total area of 2158 hectares with a potential of 6 million stems. To increase the value and health of bamboo shoots can be made with fermentation. Fermentation is done by two methods, enzimatic fermentation and spontaneous fermentation. The results of the highest crude fiber obtained in spontaneous fermentation of bamboo shoots Haur 44.46% while the highest starch content present in fermented bamboo shoots Paring stater of 13.91%. Metal content, everything is still fulfill the quality standard. Flour bamboo shoots can be used as food supplements or raw materials of fiber flour.Keywords: bamboo shoots,  fermentation, fiber flour
