Evaluation of heavy metal complex phytotoxicity

Abstract

Article Info Received : 26.12.2015 Accepted : 07.03.2016 The experimental data dealing with the effect of heavy metals contained in the technogenic contaminated soils on plant objects under controlled conditions was discussed. The aim of this work is to define the quantitative indicators of copper and zinc potential phytotoxicity, namely germination energy, simultaneous germination and duration of the test plants. It was found that the activity of the test plant growth is linked with copper and zinc complex action. Joint effect of copper and zinc is manifested both in inhibition of lettuce growth and determined, above all, by the nature contamination, soil properties and biological specificity of the test plants.

Migration Features of Copper and Zinc in Soils and Their Phytotoxicity

“…Анализ проростков осущест-вляли на 30 сутки после выращивания. Величину показателя контрольных (L 0 ) и опытных (L оп ) семян вычисляли как среднее арифметическое (L ср ) из совокупности данных о длине надзем-ной части или корней проростков [6] , n…”

“…Среди показателей прорастания се-мян в условиях модельного загрязнения почв ТМ наиболее информативными оказались ростовые показатели [6] -всхожесть, энергия, дружность и про-должительность прорастания (рис. 5-8).…”

“…При этом загрязнения могут распространяться с инфиль-трацией атмосферных осадков через слой отхода в почву примыкающих участков. При оценке экотоксиколо-гических эффектов промышленных отходов необходимо изучать их ком-плексное техногенное воздействие: с одной стороны, необходимы сведения о процессах миграции соединений из отходов в почвы, с другой стороны, важно исследовать влияние загрязни-телей, проникающих вглубь почвы, на объекты ОПС [3][4][5][6].…”

Spatial distribution of heavy metals density in cultivated soils of Central and East Parts of Black Sea Region in Turkey

“…Accumulation of heavy metals in arable soils is important because of the potential transfer of heavy metals through crops to animals (feed crops) and humans (food crops and vegetables) (De Temmerman et al, 2003). To this respect Cd, Cu, Co, Ni, and Pb are important elements, not only because of the long term accumulation in humans but also because of the high potential for root uptake and accumulation in above ground plant parts (Saglam et al, 2011;Datsenko and Khimenko, 2016).…”

Determining Heavy Metal Contents of Hollyhock (Alcea rosea L.) in Roadside Soils of a Turkish Lake Basin

“…Heavy metals such as Cd, Cu, Co, Ni, and Pb are reported as important elements not only because of the long-term accumulation in humans but because of the high potential for root uptake and accumulation in aboveground plant parts [7]. Heavy metals are among the most harmful environmental pollutants, and many researchers have reported their effects on plants and soil in areas close to main roads and motorways [8][9][10].…”
