Opis:
This study aimed to determine the effectiveness and ability of water hyacinth (Eichornia crassipes Mart. Solm) in reducing the COD and BOD levels in petroleum liquid waste. Petroleum liquid waste is one type of waste that pollutes the environment if it is not treated first. In this study, the biological treatment techniques were carried out using the phytoremediation techniques. Phytoremediation is an effort to reduce and improve the quality of waste by using plant agents so that the levels of pollutants contained in the waste can be reduced. The phytoremediation techniques are carried out using a simple bioreactor with various concentrations of petroleum liquid waste, namely control (0% waste), 10% waste, 20% waste, and 30% waste. The results of this study showed that the water hyacinth plant was able to tolerate liquid petroleum waste, which was indicated by the water hyacinth plant being able to survive up to a concentration of 30% for approximately 2 months. On the basis of the measurement of BOD and COD of petroleum liquid waste before phytoremediation was carried out, it was 20 mg/l and 10.04 mg/l, respectively. At 10% effluent concentration, the BOD and COD values decreased to 4.11 mg/l and 14.7 mg/l, respectively. At 20% effluent concentration, the BOD and COD values also showed a decrease to 3.73 mg/l and 9.14 mg/l, respectively. At 30% effluent concentration, the BOD and COD values showed a decrease to 3.73 mg/l and 1.22 mg/l, respectively. The ability of the water hyacinth plant to reduce the BOD and COD values can show its effectiveness to be used as a phytoremediation agent for petroleum waste.

Opis:
This present study to determine the potential of Neptunia oleracea as a phytoremediation agent for petroleum liquid waste in terms of various parameters such as physical temperature, and chemical parameters, namely pH, sulfide, and ammonia. Crude oil liquid waste is a hazardous waste if discharged directly into the environment, especially water. In this research, a method of biological treatment of petroleum liquid waste was used by utilizing aquatic plants, namely Neptunia oleracea. Phytoremediation is a way to treat waste that still contains contaminants thus levels can be minimized and even accumulated by various types of plants. This phytoremediation technique uses a simple bioreactor with various concentrations of petroleum liquid waste, namely control (0% waste), 10% waste, 20% waste, and 30% waste. The results of this study can be seen that the Neptunia oleracea plant is able to survive in petroleum liquid waste with a treatment time of approximately 3 weeks. In testing the levels of ammonia and sulfide after treatment showed fluctuating results from week to week. This is a response from Neptunia oleracea which uses these compounds in its metabolic processes. The ability of Neptunia oleracea to reduce sulfide and ammonia levels indicates that this plant can be used as a phytoremediation agent for petroleum liquid waste.

Opis:
Heavy metals that pose a threat to the environment include lead (Pb), zinc (Zn), copper (Cu), arsenic (As), cadmium (Cd), chromium (Cr), nickel (Ni) and mercury (Hg). Biomonitoring of environmental quality using plants is widely accepted as a reliable and inexpensive way of obtaining information on contamination also by heavy metals. It allows the assessment of the direction of changes in the natural environment and development of prognoses and methods for early warning related to predicted transformations in ecosystems. This paper presents the results of field and laboratory studies on floristic biodiversity in the areas of southern Poland related to extraction and processing of Zn and Pb ores. The paper also shows the selected plant defence mechanisms against the excess of heavy metals and the results of bioindication studies using different plant species, including the selected metallophytes related to the assessment of contamination levels and the most frequently used plant ecophysiological parameters. It is necessary to monitor contamination level, popularize knowledge and take action at the level of local authorities to mitigate adverse effects of human activity, bearing in mind possible bioaccumulation of heavy metals in the food chain and the adverse health effects associated with environmental contamination.

Opis:
Concentration of seven (7) metals (Pb, Cu, Zn, Mu, Ni, Cr, and Cd) in the samples of soil and some plant species collected from Kachia military shooting range were determined. The mineral ions were assayed using the acid digestion method and atomic absorption spectrophotometry (AAS). Physicochemical parameters (pH, EC, Bulk density, water holding capacity and Total Nitrogen) of the soil samples were also determined. Of the 7 metals determined in the soils samples, the concentration of Pb (14.85 ± 6.78 mg/kg-1) was the highest compared to the concentrations of other metals. Physicochemical parameters were within the range that allows effective phytoremediation. Cu showed the lowest concentration (0.55 ± 1.68 mg/kg-1). Ni was below the detectable limit in most of the samples. Similarly, concentrations of Pb (12.30 mg/kg-1) in the shoot of Albizia zygia among other metals were higher than those of the other metals in the plant tissues. Concentration of Cd (0.07 mg/kg-1) in the root of Eragotis tremula was the lowest. Generally, metal ion concentration in the soil and plant samples of the shooting range (polluted site) significantly) differed from those of the non-polluted site (P<0.05). Combretum hispidium among the plant species had the highest translocation factor (TF = 2.91). Although the TF was higher in the plant of the polluted site TF >1), reasonable amount of them were retained within the underground tissues (roots).

Opis:
Both theoretical models and pharmacological dissection suggest that Cs+ influx to arabidopsis root cells occurs through voltage-insensitive cation channels (VICCs), encoded by members of the AtCNGC and AtGLR gene families, and 'high-affinity' K+/H+ symporters (KUPs), encoded by members of the AtKUP/AtHAK gene family. When arabidopsis have sufficient K, it is observed that VICCs mediate most Cs+ influx to root cells. However, KUPs contribute more to Cs+ influx in roots of K-starved plants. This phenomenon has been attributed to an increased expression of AtHAK5 in roots of K-starved plants. Curiously, although arabidopsis mutants lacking some AtCNGCs show reduced Cs accumulation, mutants lacking other AtCNGCs accumulate more Cs in their shoot than wildtype plants. It is hypothesised, therefore, that the expression of genes encoding diverse K+-transporters might be altered to compensate for the absence of AtCNGCs that contribute significantly to cellular K homeostasis. Increased Cs+ influx and accumulation could then be explained if the lack of an AtCNGC caused a physiological K-deficiency that increased the expression of AtKUPs. Such observations imply that the consequences of a simple genetic manipulation, such as the mis-expression of a AtCNGC gene, on Cs+ influx and accumulation might not be predicted a priori. Finally, since AtCGNCs, AtGLRs and AtKUPs have contrasting Cs+:K+ selectivities, and their relative expression is determined by diverse environmental variables, both the Cs:K ratio in plant tissues and the absolute rates of Cs+ influx and accumulation will depend critically on environmental conditions. This will impact on strategies for phytoremediation and/or the development of 'safer' crops for radiocaesium-contaminated land.

The lead contamination of the environment affects the life of organisms, as the quality of the environment influences and determines the quality of living things, both plants and animals. Therefore, remediations need to be taken so that the polluted land could be repurposed for various activities safely. Phytoremediation is a method that employs plants to move, detach, or stabilize pollutants in the form of eitherorganic or inorganic compounds. In this study, the Croton (Codiaeum varigatum) plant was used as a phytoremediator planted in pots. Three pots were observed: 500 mg of Pb (NO3)2 was added to the first (T1) pot, 750 mg (T2) of Pb (NO3)2 was added up to the second (T2) pot, and no addition to the third (T0) pot. The parameters analyzed included plant biomass, the Pb content in plants, bioaccumulation factors, translocation factors, metal tolerance index, and photosynthetic pigment content. The results showed that Pb affected all of the analyzed parameters. Pb causes a decrease in the plant biomass and a downturn in chlorophyll a and b. The Pb accumulation in root > stem > leaf. The BAF value <1, the TF value <1 and the MTI value ranged 89.73–82.80%.

Opis:
Using water hyacinth as a phytoremediation agent produces abundant biomass due to periodic harvesting in the system. One of the alternative uses of water hyacinth biomass can be a bio-sorbent to absorb metal contamination in the waters. This study aims to determine the quality of activated water hyacinth bio-sorbent, potentially reducing metal cadmium (Cd). The research was conducted from January to April 2022. The results showed that the parameters of water content, iodine absorption, and methylene blue in water hyacinth bio-sorbent had met the quality standard of activated carbon based on SNI No. 06-3730-1995. In contrast, the ash content still did not. In water, hyacinth stem bio-sorbents (stems + ZnCl2 and stems 300 °C + ZnCl2) obtained higher ash content (25.87 and 73.30%) than the ash content of water hyacinth root and leaf bio-sorbent with the same activation treatment. The optimum adsorption capacity (Qe) for the roots + ZnCl2 occurred at a contact time of 45 minutes which was 8.13 mg/g with an absorption efficiency (Ef) of 34.20%. For the root 300 °C + ZnCl2, the optimum adsorption capacity and absorption efficiency occurred at a contact time of 8 hours, namely 9.08 mg/g and 38.66%, respectively. The optimum adsorption capacity and absorption efficiency of the leaves + ZnCl2 occurred at a contact time of 4 hours, namely 7.63 mg/g and 32.12%, respectively. Meanwhile, at the leaves 300 °C + ZnCl2, the optimum adsorption capacity and absorption efficiency occurred at a contact time of 8 hours with a value of Qe = 11.84 mg/g and Ef = 49.35%.

Water is an important part of all living things, including humans, animals, and plants, but concern for clean water is decreasing due to numerous human activities, which cause pollution. Water pollution is characterized by changes in physical, chemical and biological contents due to the wastes generated from the actions of living things, such as water irrigation. Therefore, this research aimed to overcome irrigation wastewater pollution using the Internet of Things (IoT)-based phytoremediation method, water hyacinth, apu-apu, and lotus. It was carried out using a tool monitoring system based on IoT technology with parameters for measuring pH, temperature, and water turbidity through the internet network. The results showed that the acidity level increased by 7–8 with a decrease in COD using water hyacinth, apu-apu, and lotus by 41.55%, 32.77%, and 32.91%, respectively. The BOD level using water hyacinth, as well as apu-apu and lotus decreased by 37.82%, and 31.54%, respectively. The decrease in phosphate level using water hyacinth, apu-apu and lotus was by 3.55%. Finally, the decrease in nitrate level using water hyacinth plants, apu-apu and lotus was 13.83%, 9.61% and 19.61%, respectively.

Effluents from industries contain appreciable amount of metallic cations like zinc, copper, iron, manganese, lead and cadmium. Release of heavy metal without proper treatment poses a significant threat to public health because of its persistence biomagnifications and accumulation in food chain. To reduce metal pollution problems many processes have been developed for the treatment and disposal of metal containing wastes. Certain plants have the ability to accumulate heavy metals such as Pb, Cr, Cd and Zn. At present, phytoremediation of metals may be approaching commercialization. Hence, possibility can be explored to remove heavy metal load, present even in low concentration, in waste water of paper mill effluent soil by using Croton sparsiflorus.

Opis:
Phytoremediation is an acceptable, economical, and eco-friendly way to remediate the metal contaminated soils beside the industrial zone. Like other industries, the textile industries generate the effluent containing several types of pollutants such as metal conjugated dyes, several inorganic and organic substances, etc. When discharged to the environment, metals - specifically heavy metals - exert an adverse impact on soil and other biotas through the food chain. In this study, Bryophyllum pinnatum was used for phytoremediation in the contaminated soil sample collected from the area located around textile industries in Kaliakair, Bangladesh. The experiment was carried out by ex-situ in earthen pots. The concentration of six heavy metals including Zn, Cu, Ni, Cr, Pb, and Cd was analyzed before applying phytoremediation. Two heavy metals, Cu (28.57 µg/g) and Zn (143.88 µg/g) were found and others were not detected in that soil. After planting of Bryophyllum pinnatum, the concentrations of Cu and Zn in the contaminated soil were analyzed at three intervals of 45 days (S3), 90 days (S4), and 135 days (S5) in three replications. The experiment revealed that there was a decline in the concentration of Cu in soil (27.08 µg/g for 45 days and 13.19 µg/g for 90 days) except for the 3rd replication of 135 days (S5). However, the concentration of Zn (mean 103.09 µg/g) in soil was measured at 45 days and then remained within nearer values of concentration for other replications. The amounts of heavy metals uptake for both Cu and Zn by plants can be presented as leaves> stem >root which indicated that heavy metals were transferred from root to shoot over time. Bryophyllum pinnatum can, therefore, be considered as a good hyperaccumulator plant having BCF>1 and TF>1 values as well as possessing a better capacity of phytoextraction of metals.

Opis:
The present study investigated the efficiency of four aquatic macrophytes: Lemna spp, Pistia stratiotes, Ipomoea aquatica and Eichhornia crassipes on nitrogen and phosphorous utilization from aquacultural effluents concerning seasonal changes and biomass production. These nutrients in excess affect fish health and cause eutrophication in water bodies, hence affecting the ecosystem. Aquatic macrophytes were planted in tanks filled with the effluents from carp pond and other tanks were left without plants, serving as control/algal treatment. The water samples were collected weekly for analysis of total nitrogen (TN), ammonia-nitrogen (NH3-N), nitrate-nitrogen (NO3-N), total phosphorus (TP) and ortho-phosphate (ortho-P). The results show that average water temperature raised from 12.2 ± 0.21 °C in winter to 32.0 ± 0.4 °C in summer with no significant difference (p>0.05) between treatments whereas pH was neutral in winter and slightly alkaline in the other seasons. Seasonal changes had impact on macrophytes biomass accumulation with the highest in spring for Lemna spp (91.3%), followed by P. stratiotes (81%) and in summer, E. crassipes (64%). Autumn and winter had the lowest biomass accumulation and I. aquatica had the lowest values in all seasons. For each season, the nutrients concentration decreased with no significant difference (p>0.05) between treatments. Average NH3-N removal efficiencies were higher during summer and autumn followed by spring and lowest in winter for all treatments. NO3-N and TN decreased significantly from the highest in summer to the lowest in winter in all treatments. The ortho-P removal efficiency was slightly higher than TP and decreased from the highest in spring to the lowest in winter (91.4% to 7.8%, control/algae; 90.3% to 8.4%, E. crassipes; 86.2% to 8.3%, Lemna spp; 82.5% to 10.8%, P. stratiotes). The chlorophyll a concentration was higher in Lemna spp (62.2 μg/L) and control/microalgae treatments (59.3 μg/L) indicating that there was probably microbial community that contributed to nutrient utilization. Aquatic macrophytes, in association with microalgae, were responsible for the nitrogen and phosphorous removal. Seasonal temperature change affects the growth and nutrients uptake of aquatic macrophytes. A decrease in temperature reduces the efficiency of nutrients removal and biomass production. For an effective N and P removal from pond effluents in a given season, selection of a proper aquatic macrophyte must be taken into consideration with regards to a given season.

The use of phytomeliorant plants is one of the promising trends in environmental biotechnology to purify waste water. The study was carried out to understand the phytomeliorative qualities of plants of the indigenous flora of the Turkestan Region under controlled conditions and to develop a method for treating wastewater. It was established that the use of a three-stage treatment of municipal wastewater using phytomeliorant plants: Ceratophуllum demersum L., Potamogeton trichoides Cha. Et Schlecht., Potamogeton pectinatus L., Potamogeton natans L.; Cardamine densiflora N. Gontsch., Sium sizaroideum DC.; Veronica beccabunga L, Veronica anagallis aquatica L. and Azolla caroliniana Willd for 30 days of the controlled experiment reduces the content of organic and mineral ingredients to the MPC values. A method for phyto-meliorative wastewater treatment of one of the sanatoriums in the south of Kazakhstan was developed and carried out in multi-stage bioponds, where water was purified from mineral and organic compounds by 94.9 ± 8.3 – 98.9 ± 7.8% in 12 days. In this study, first of all, nitrogenous compounds were utilized, then there was an active absorption of mineral ions and residual organic matter by plants. In conclusion, significant purification of wastewater was achieved by using indigenous phytomeliorant plants in much shorter time period.

An analysis of energy plants from the point of view of their suitability for remediation of oil-contaminated territories was carried out. Plantations of Salix viminalis L., Helianthus tuberosus L. and Medicago sativa L. were planted with the purpose of remediation of the territory where active oil production is conducted. The prospect of using Salix viminalis and Helianthus tuberosus as effective restorers of technogenically-transformed environment quality was revealed. The limiting factors restricting the growth of Salix viminalis on degraded soils were established, involving dry air and insufficient soil moisture. Medicago sativa is sensitive to the level of soil contamination by pollutants and can act as a phytoindicator of the environmental quality of oil-contaminated ecosystems.

Opis:
The performance of electrically stimulated phytoremediation in the removal of lead, cadmium and copper was assessed in this study. A combination of phyto and electro remediation was attempted in this study for the remediation of the metals from water. Three tanks were setup with different operating conditions for this experiment: control A (only phytoremediation system), control B (only electro remediation) and treatment (combination of phyto and electro remediation). The electrically enhanced phytoremediation system and electro remediation system were operated 2h/day at voltages of 4V for 25 days continuously. In this experiment, the Eichhornia crassipes, an able phytoremediator exhibited efficient and fast removal of heavy metals from synthetic solution in electro assisted phytoremediation system. The electrically enhanced phytoremediation using aluminum sheet electrodes showed better and effective removal of Cd, Pb and Cu than aluminum rod electrodes. A more favorable and moderate increase of pH was noticed in electrically stimulated phytoremediation system. Eichhornia crassipes has tremendous potential to reduce maximum amount of cadmium (within 15 days), lead (within 15 days) and copper (within 10 days) under electrically stimulated condition. Under electrified condition, maximum amount of Cd and Cu was accumulated in the aerial parts of Eichhornia crassipes but maximum concentration of Pb was attained by roots. This indicates the high heavy metal accumulation capacity of Eichhornia crassipes under electrified conditions. The results showed that 4V voltage is probably suitable to stimulate the Eichhornia crassipes to synthesize more chlorophyll and voltage can improve growth and ability to resist adverse circumstances by promoting chlorophyll synthesis. Eichhornia crassipes stimulated by an electric field has grown better and assimilated more metal. Bioconcentration factor (BCF) an index of hyperaccumulation, indicates that electrically stimulated Eichhornia crassipes is a good hyper accumulator of Cd (BCF = 1118.18) and Cu (BCF = 1152.47) and a moderate accumulator of Pb (BCF = 932.26). Translocation ability (TA) ratio indicates that Eichhornia crassipes have the ability to translocate more amounts of Pb, Cd and Cu to its upper portion under electrified condition. The results imply that the electro-phytoremediation technique seems to be promising in the treatment of wastewater contaminated with heavy metals.

Opis:
Research addresses the issue of assessing the possibility of using birch and willow trees in phytoremediation of acidic waste settlers. In order to determine the suitability of these trees to bio-accumulate metals it was crucial to first characterized the physico-chemical parameters of the waste. Both waste and leaves samples were analyzed with respect to heavy metals concentration using microwave digestion (cone. HNO3) procedure followed by AAS analyzes. Moreover, the mobility of contaminants from waste was studied using aqueous leaching test as well as sequential extraction procedures. Investigated waste is very inhomogeneous and is characterized with diversity of pH values within sampling points (2.9-7.0) as well as with high concentration of SO42 anions (1203-1301 mg/dm3), Fe (11-19%) and Zn (64-172 mg/kg). Ability to accumulate metals in birch and willow leaves is high. In birch leaves Zn was accumulated up to toxic level of 431 mg/kg, Mn up to 790 mg/kg, Cu up to 9 mg/kg, Pb up to 21 mg/kg. In willow leaves Zn concentration were found to be even higher and reached 679 mg/kg. Concentrations of remaining metals in willow leaves were as follows: Mn up to 173 mg/kg, Cu up to 17 mg/kg and Pb up to 10 mg/kg. Research results confirmed that both birch and willow trees growing on settlers have high tolerance to the adverse living conditions caused by metal stress and low pH of the foundation. These trees can be used for the purpose of phytoremediation of investigated waste settlers.
