Abstract

Phytoremediation is a practical, environmentally-friendly, low-cost technological solution used to clean various types of pollution, including metals, pesticide residues, and oils from contaminated soil and water. In this study, Cordyline fruticosa was planted in the lead-contaminated soil. Each pot was given 250 mg/kg and 375 mg/kg of lead. The parameters observed included biomass (mg), lead content in the root, stem, and leaf, bioaccumulation factor, translocation factor, metal tolerance index, and amount of metal extraction, which were analyzed after 30, 60, and 90 days. The results revealed that root, stem and leaf biomass (g) were significantly different from control (T0). The lead contents were root<stem <leaf, while the translocation factor value was more than one, except for lead exposure 375 mg/kg (T2) in the second month and 250 mg/kg lead (T1) in the third month. The bioaccumulation factor for all treatments was less than one, and the metal tolerance index ranged from 90.87% - 93.07%. Besides, the amount of root metal extraction was smaller than the shoot. In sum, C. fruticosa is potential phytoremediation.

Abstract

The study was aimed to compute Pb and Cd bioaccumulation in different organs of broiler. Carcass, heart, liver, gizzard, intestine, and excreta. The data were obtained from broiler reared in the litter cage. Four treatments of feed were given to the broiler chicken, i.e.  T1 = X brand of commercial feed, T2 = Y brand of commercial feed, T3 = self-prepared feed without fish meal addition and T4 = self prepared feed without fish meal but contaminated with cadmium chloride (Cd.Cl2.4H2O). For each treatment, five broiler chicken were grouped each week (from week I up to week VI). Results of the first stage of this study was analyzed descriptively. A polinomial regression equation was used as an empirical model to describe the heavy metal bioaccumulation phenomenon in broiler carcasses. The quadratic equation  turned out to be the most suitable model for describing the bioaccumulation of heavy metal in broiler carcasses. From the simulation, it was found that  quadratic model fit to 61.31% and 54.17%  bioaccumulation data of Pb and Cd respectively. According to the model, initially metal concentrations declined since the first week and started to rebound at the fifth week, both in terms of chronological and physiological age. The patterns of Pb and Cd bioaccumulation in this study can be used as a reference to determine the proper slaughter period. It can be concluded that for reducing the risk of metal contamination the proper slaughter time of the broiler is before the fifth week.
