the present study aimed at investigating and estimating the amount of damage caused by waste water pollution of water desalinators in the south pars special zone. the main reasons for conducting this study were to investigate the creation of environmental pollutants as a result of the development and expansion of different industries in the south pars zone, as well as the ecological sensitivity...

knowledge of the probable origin and behaviour of arsenic certainly gives valuable insights into the potential for transfer in the environment and of the risks involved in mining sites. sequential extraction analyses are common experiments often used to study the origin and behaviour of potentially toxic elements. the method, however, presents some deficiencies, including labor-intensive proced...

The Kirki project aimed to identify, among the mining waste abandoned at a mine and processing plant, the most critical potential pollution sources, the exposed milieus and the main pathways for contamination of a littoral area. This was accompanied by the definition of a monitoring network and remedial options. For this purpose, field analytical methods were extensively used to allow a more pr...

A portable flow analysis instrument is described for in situ photometric measurements. This system is based on light-emitting diodes (LEDs) and a photodiode detector, coupled to a multipumping flow system. The whole equipment presents dimensions of 25 cm x 22 cm x 10 cm, weighs circa 3 kg, and costs 650 euro. System performance was evaluated for different chemistries without changing hardware c...

We investigated the suitability and applicability of Pseudevernia furfuracea (L.) Zopf for environmental genotoxicity assessment. P. furfuracea lichen specimens were collected from 10 different Pinus species, in every 5 km, starting from around an iron-steel factory located in the central area of Karabük Province up to Yenice Forest. The impact of the pollution sources such as iron-steel f...

Exposure and ecological risks to heavy metals (copper, zinc, manganese, iron) at Lochnivar and Blue Lagoon National Parks in wildlife dependent on the Kafue river contaminated with mining waste was evaluated. Samples included water, fish, grasses and Kafue Lechwe (Kobus leche kafuensis) liver. At both parks copper ranged from 0.03-0.04 mg/l; 3.0-6.0 mg/kg; 11.0-44.0 mg/kg; trace -199.0 mg/kg; w...

The paper describes the properties of some nanopowders obtained by coprecipitation and used as adsorbent for wastewater treatment. The Fe3O4 and γ-Fe2O3 nanopowders were obtained using iron salts and NaOH as precipitation agents. D-sorbitol was used to prevent the agglomeration between the nanoparticles. The particle size and distribution were detected using a transmission electron microscopy (...

The main idea of the presented work is to examine the effect of adding industrial waste in the form of Gray Cast iron (GCI) and Ductile Cast Iron (DCI) from the casting industry in the concrete mix. GCI and DCI turnings were used as a partial replacement material for the usual fine aggregates to study the effect on compressive strength and flexural strength of the mix. Partial replacement of fi...
