copper is an essential micronutrient for plant growth which is involved in many metabolic processes. however excessive amounts of copper may cause environmental pollution. with an increase in the contamination of urban areas with heavy metals, more attention should be paid to the role of ornamental plants in removing pollutants from the soils. the effects of heavy metals on the growth parameter...

The contamination of agricultural soils by heavy metals is a global problem. Soil texture as a biotic factor represents one of the most important factors that influences the distribution of organic matter and ultimately play decisive role in retention of heavy metals in soil ecosystem. The effects of heavy metals on soil microbial processes were investigated. Analytical grade sulphate and chlor...

demand for water resources in different parts of the world, necessitate the use of wastewater. in using wastewater the soil health must be considered. this study was carried out at green space zob ahan in the years 1382 to 1385. in this study, the effects of urban and industrial wastewater irrigation on some chemical properties of soil for three years by using five different irrigation treatmen...

Due to the determination of the pollution status of fresh resources in the Egyptian territorial waters is very important for public health; this study was carried out to reveal the levels of heavy metals in the shellfish and their environment and its relation to the highly developed industrial activities in those areas. A total of 100 shellfish samples from the Rosetta, Edku, El-Maadiya, Abo-Ki...

Alga as Achnanthes minutissima among diatoms is a widely adaptable taxon on the state of an aquatic environment. In this study, it was found that diatom had a specific tolerance to heavy metals (Cu, Zn, Pb, and Cd etc.) in river water samples, because the diatom assemblage consisted of almost only Achnanthes minutissima in Kakehashi river and Godani river, which were polluted with waste water f...

Background and Objectives: Despite the increasing impact of heavy metal pollution in Persian Gulf due to urban growth and agricultural and petroleum activities, few studies have focused on the behavior and relationships of these pollutants in the biotic and abiotic components of aquatic environments. In this study, the amount of some metals (copper, iron, lead, cadmium, zinc and nickel) was det...

The protease inhibitive assay for heavy metals is a novel and robust detection method suitable for preliminary screening method for detecting heavy metals in agriculture and environment samples. Stem bromelain has been previously showed to be sensitive towards mercury and copper. However, commercial preparation is in crude form and contains possible interfering entities. Using ion exchange and ...
