AbstractWe investigated the concentration of Aluminium (Al), Cobalt (Co), Chromium (Cr), Copper (Cu), Iron (Fe), Manganese (Mn), Nickel (Ni) and Zinc (Zn) in the root and aboveground organs of four halophyte species (Salicornia europaea, Suaeda maritima, Salsola soda and Halimione portulacoides), as well as in the soil from maritime and inland saline areas. The aim of our research was to evaluate the capability of some halophyte species to absorb different heavy metals and to detect differentiation of heavy metal accumulation within populations from inland and maritime saline areas. Generally, the plant roots had significantly higher concentrations of metals when compared to stems and leaves. Zinc was the only metal with concentrations significantly higher in the leaves than in the root and stem. Populations from maritime saline areas had higher trace root and stem metal concentrations than populations from inland saline areas. Excepting zinc, populations from inland saline areas had higher heavy metal concentrations in the leaves. The factors that affected metal accumulation by halophytes included the percentage of salt in the soil. We also discuss the potential use of these halophytes in phytoremediation.

Irrigation Waters

The reuse of wastewaters for agricultural irrigation is a method used in arid and semi-arid regions. The heavy metal accumulation in soils caused by wastewaters and the heavy metals transported by the waters leaching into the underground from these soils are important environmental issues. The study investigates the effects of Biochar (Bc) and Zeolite (Zt) applications on the heavy metal accumulation in soils (entisol and vertisol) that were irrigated with treated urban wastewater (TWW). The effects of Bc and Zt on the heavy metal concentrations of the leaching water (LW) from the soils were investigated as well. In the study, increasing doses of Bc (1%, 2%, and 4%) and Zt (5%, 10%, and 20%) were mixed into two soil classes of heavy- and fine-textured soils. The mixtures were irrigated with TWW at certain intervals. At the end of the trial, the chromium (Cr), iron (Fe), nickel (Ni), cobalt (Co), copper (Cu), lead (Pb), and cadmium (Cd) contents of the samples collected from the soils and leaching irrigation waters were determined. The results revealed that Bc and Zt caused heavy metal accumulation in both soil classes, while they decreased the heavy metal concentrations of the LW. The adsorbents are commonly used as soil amendments and have been determined to cause heavy metal accumulation in soils but reduced the heavy metal concentrations in waters by serving as filters.

This study was carried out to determine the possible heavy metal accumulation in fruits and leaves of Zivzik pomegranate (Punica granatum L.) grown in two different roadside orchards located in Pirinçli and Kapılı villages of Siirt province, Turkey. Leaf and fruit samples were collected from trees located at 0, 50, 100 m distances from the main roads. Plant samples were analyzed for cobalt (Co), nickel (Ni), cadmium (Cd), lead (Pb) and chromium (Cr) concentrations. The Co, Ni, Cd, Pb and Cr concentrations of fruit samples collected from Pirinçli village were ranged from 0.082 to 0.238 mg kg−1, from 1.160 to 1.559 mg kg−1, from 0.087 to 0.179 mg kg−1, 0.326 to 0.449 mg kg−1 and 0.606 to 1.054 mg kg−1, respectively. The Co, Ni, Cd, Pb and Cr concentrations of fruit samples from Kapılı village were between 0.085 and 0.137 mg kg−1, 1.042 and 1.123 mg kg−1, 0.037 and 0.076 mg kg−1, 0.277 and 0.520 mg kg−1 and 0.762 and 0.932 mg kg−1, respectively. Heavy metal concentrations of leaf samples from Pirinçli village varied from 0.191 to 0.227 mg Co kg−1, 2.201 to 3.547 mg Ni kg−1, 0.051 to 0.098 mg Cd kg−1, 0.535 to 0.749 mg Pb kg−1 and from 1.444 to 2.017 mg Cr kg−1. Similarly, the heavy metal concentration of leaf samples from Kapılı villages were between 0.213 and 0.217 mg Co kg−1, 2.160 and 2.511 mg Ni kg−1, 0.058 and 0.114 mg Cd kg−1, 0.579 and 0.676 mg Pb kg−1 and 1.688 and 1.518 mg Cr kg−1. The Co, Ni and Cr concentrations in fruit samples collected from 0, 50 and 100 meters to the main road in Pirinçli village were at statistically significant level, while only Ni concentration in leaf samples collected from 0, 50 and 100 meters to the main road was at significant level. In contrast, heavy metal concentrations in fruit and leaf samples collected from 0, 50 and 100 m to the main road in Kapılı village were not statistically significant level.

The spatial complexity of floodplains is a function of several processes: hydrodynamics, flow direction, sediment transportation, and land use. Sediments can bind toxic elements, and as there are several pollution sources, the risk of heavy metal accumulation on the floodplains is high. We aimed to determine whether fluvial forms have a role in metal accumulations. Topsoil samples were taken from point bars and swales in the floodplain of the Tisza River, North-East Hungary. Soil properties and metal concentrations were determined, and correlation and hypothesis testing were applied. The results showed that fluvial forms are important drivers of horizontal metal patterns: there were significant differences (p < 0.05) between point bars and swales regarding Fe, K, Mg, Mn, Cr, Cu, Ni, Pb, and Zn. Vertical distribution also differed significantly by fluvial forms: swales had higher metal concentrations in all layers. General Linear Models had different results for macro and micro elements: macro element concentrations were determined by the organic matter, while for micro elements the clay content and the forms were significant explanatory variables. These findings are important for land managers and farmers because heavy metal concentration has a direct impact on living organisms, and the risk of bioaccumulation can be high on floodplains.

Abstract Heavy metal accumulation in vegetable tissues often poses a great risk for human health. In the present study, accumulation of heavy metal in green leafy vegetable crops of coriander, garden cress, lettuce and spinach were evaluated under waste water irrigation in fields located in Kahrizak, on the southern edge of the metropolitan city of Tehran, Iran. Atomic absorption spectrophotometery was used for determination of heavy metal concentrations in leaf tissue. The results showed that heavy metal concentrations in soil and irrigation water were significantly high than allowable levels. Analysis of plant leaf tissue showed that spinach and garden cress accumulated higher concentrations of heavy metals compared to coriander and lettuce plants. Central leaves of lettuce showed the lowest heavy metal concentration compared to outer leaves or leaves of other vegetable crops, and can be the safer product for fresh consumption. The results indicate that the vegetables produced in the region are not suitable for fresh consumption and the agricultural activities should change towards ornamental or industrial crops production.

The concentration of heavy metals(Zn, Ni, Pb, Cd and Cu) in the muscle of three fishery organisms (Chrysicththysnigrodigitatus, Sarotherodongalilaeus and Peneausmonodon)and in environmental samples of waterand sediment were tested in Yewa Lagoon, Nigeria. Five fishing villages along the lagoon were selected as the sample sites where these metals were tested. The heavy metal content in the muscle of the fishery organisms was Zn > Ni >Pb> Cu > Cd;Zn > Ni >Pb> Cd > Cu and Zn > Ni >Pb> Cd > Cu inC.nigrodigitatus, S.galilaeus and P.monodon respectively. The heavy metal concentrations in the sediment was Zn >Pb> Cu > Ni > Cd. However, nickel and cadmium were not present in the water at two sampling sitesof Yewa Lagoon.The water of Yewa Lagoon is polluted with all the five heavy metals which were all higher than the WHO standard. The concentration of Zinc in the fishery organisms were below the WHO standard. However, the high concentration of zinc in the water (which is well above the WHO standard) could be associated with the fact that zinc is naturally abundant in Nigeria soils.

Enhanced weathering is a promising approach to remove carbon dioxide from the atmosphere. However, it may also pose environmental risks through the release of heavy metals, in particular nickel and chromium. In this perspective article I explore the potential role of plants in modulating these heavy metal fluxes. Agricultural basaltic soils may be valuable study sites in this context. However, the effect of biomass harvesting on the accumulation of heavy metals is currently not well studied. Mostly caused by different parent rock concentrations, there is a large variability of heavy metal concentrations in basaltic and ultramafic soils. Hence, to minimize environmental risks of enhanced weathering, basalts with low heavy metal concentrations should be favored. Existing phytoremediation strategies may be used to “phytoprevent” the accumulation of nickel and chromium released from enhanced weathering in soils. As a result, elevated nickel and chromium concentrations in rocks must not preclude enhanced weathering in all settings. In particular, hyperaccumulating plants could be used as part of a crop rotation to periodically remove heavy metals from soils. Enhanced weathering could also be employed on fields or forests of (non-hyper) accumulating plants that have a high primary production of biomass. Both approaches may have additional synergies with phytomining or bioenergy carbon capture and storage, increasing the total amount of carbon dioxide drawdown and at the same time preventing heavy metal accumulation in soils.

Проведены научнохозяйственный и физиологический опыты на молочных коровах чёрнопёстрой породы на ферме агротехнического техникума Новгородский в Новгородской области. Группы коров сформированы методом группаналогов с учётом возраста, живой массы, продуктивности за предыдущую лактацию свыше 6 тыс. кг молока, происхождения, породности и сроков осеменения. Количество коров по 10 голов в каждой группе. Цель исследования повышение полноценности и качества кормления коров на 8 9м месяце стельности. В задачи входило изучение влияния используемых фитопротекторов в рационе коров на снижение степени загрязнённости молока и организма тяжёлыми металлами. Опыт состоял из подготовительного (10 дней) и учётного (60 дней) периодов. Физиологический опыт проведён на фоне научнохозяйственного опыта продолжительностью 10 дней. Применение сушёных овощных культур (свёклы столовой и моркови кормовой) и экстракта хвойного натурального в рационах коров в 8 9 месяцев стельности обусловило снижение концентрации тяжёлых и токсичных металлов в молоке высокопродуктивных коров чёрнопёстрой породы с годовой продуктивностью 6000 кг в условиях антропогенного загрязнения окружающей среды. Тип кормления силосносенной. На фоне основного рациона (ОР) животным опытных групп скармливали дополнительно по 30, 50 и 80 г на голову в сутки свёклы и аналогичное количество моркови (кормовой). Экстракт хвойный натуральный (жидкий) в дозе 5,0 мл/гол скармливали в смеси с комбикормом. Свёкла столовая, морковь и экстракт хвойный натуральный (жидкий) с высокими антиоксидантными и сорбционными свойствами в смеси с комбикормом рационов дополняли организм коров комплексной смесью витамина С, витаминов группы В, витамина Е, селена, пряноароматических растений, позволяли более успешно решать проблемы, связанные с обменом веществ, накоплением тяжёлых металлов в молоке животных при круглогодовом стойловом способе содержания. Изучаемые фитогенные кормовые добавки обусловили повышение переваримости питательных веществ рационов, существенное снижение накопления в организме Zn, Cu, Pb, Cd, As, Hg, Fe2. Experiments on blackandwhite cows took place on the farm of the college Novgorodskiy. Analoguegroups were formed according to cow age, weight, milk productivity of over 6 thousand kg, origin, breed and mating time. Each group contained 10 heads. The aim was to improve forage composition and quality for the 8 9th month of cow gestation. One of the objectives was to study the influence of feed additives on heavy metal content in milk and cow organisms. The experiment had preliminary (10 days) and testing periods (60 days). Physiological tests lasted 10 days. Dried beet and carrot as well as coniferous extract reduced heavy and toxic metal concentration in milk. The diet included silage and hay. Cows consumed additionally 30, 50 and 80 g/head of beet and carrot daily. Coniferous extract (5.0 ml/head) was mixed with feedstuff. The additives had good antioxidant and sorption properties and provided livestock with vitamin C, B, E, and selenium. They improved cow metabolism and decreased heavy metal accumulation when keeping the livestock indoor for the entire year. The feed additives increased nutrient digestibility and reduced the accumulation of Zn, Cu, Pb, Cd, As, Hg, Fe2 in cow organisms.

The concentration of Cd, Co, Cu, Fe, Mn, Ni, Pb, and Zn in Oreochromis niloticus(generally called Tilapia fish) was assessed at three different locations along Agodi Reservoir in Ibadan. Their relative concentrations were determined using Atomic Absorption Spectrophotometer (AAS). Test location differences and seasonal variations of the values were examined using statistical analysis of variance at P<0.05 to establish pollution dynamics. The results showed declining order of heavy metal concentrations in the order of Mn>Fe>Zn>Cu>Co>Cd>Pb>Ni. Gradient effect was indicated. While Cd was found in decreasing order of concentration from inlet to the outlet, other metals like Co, Cu, Fe, Mn, Ni, Pb, and Zn had concentrations that gradually increased from inlet to the outlet.The concentration of Cd, Co, Cu, Pb, and Zn did not change considerably with season unlike Fe, Mn, and Ni that exhibited substantial seasonal variation. It was concluded that heavy metal accumulation caused marked pollution dynamics inside the Agodi Reservoir. Also, bio-accumulation of the metals in Oreochromis niloticus could give birth to location and seasonal dependency.
