The concentration of some heavy metals: Al, Ca, K, Fe, Ti, Mg, Mn, V, Cr, Zn, Ni and Co in sediments from Pulicat Lake to Vadanemmeli along Chennai Coast, Tamil Nadu has been determined using EDXRF technique. The mean concentrations of Mg, Al, K, Ca, Ti, Fe, V, Cr, Mn, Co, Ni, and Zn were found to be 1918, 25436, 9832, 9859, 2109, 8209, 41.58, 34.14, 160.80, 2.85. 18.79 and 29.12 mg kg-1 respec...

In Poland’s largest mining district, the Upper Silesian Coal Basin, there is a growing interest in resource development by small operators. Some concession areas are not yet directly affected industry. The objects of this research two such and goal to determine load heavy metals (HM) soils prior projects assess extent their contamination at stage. studied were Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn, wh...

The development of controlled-release formulations of alachlor to diminish its leaching in sandy soils, avoiding groundwater contamination and maintaining its efficacy, was studied. For this purpose, ethylcellulose (EC) microencapsulated formulations (MEFs) of alachlor were prepared under different conditions and applied to soil columns to study their mobility. The results show that in all case...

It is a well–known fact that heavy metal pollution in sediments causes serious problems not only the Danube basin, but also large and small adjacent river streams. A suitable method for assessing level of metals their toxicity calculation indices. The present research aims to assess Lower surface collected along course (between 180 60 km) up point where River flows into Delta Biosphere Reserve ...

In this study, the sequential extraction method was applied to extract selected potentially toxic elements (PTEs) (Cd, Cr, Cu, Fe, Ni, Pb and Zn) in river sediments collected from Blood River situated Seshego area, Limpopo Province, South Africa. The study aimed assess a possible trend of mobilisation these sediment water. accuracy confirmed by analysing sediment-certified reference material, q...

Heavy metal contamination in aquaculture farm sediment may create a major risk to ecosystem and human health via the food web as result of poor handling, incorrect waste management, extensive use artificial feed increase yield make profit. In this study, heavy metals (e.g., Cd, Cr, Pb, Cu, Zn, Mn, Ni) were analyzed examine accumulation, sources, levels from bottom samples 12 different commercia...

This research intends to offer a scientific foundation for environmental monitoring and early warning which will aid in the protection management of Qaroun Lake. Lake is increasingly influenced by untreated wastewater discharge from many anthropogenic activities, making it vulnerable pollution. For that, six pollution indices, namely contamination factor (Cf), enrichment (EF), geo-accumulation ...

Kadmium (Cd) merupakan logam berat berbahaya yang dapat mengakibatkan terjadinya pencemaran di perairan. Penelitian ini bertujuan untuk mengetahui kandungan Cd pada matriks air, sedimen, dan ikan nilem (O. hasselti) Sungai Tajum, Banyumas serta tingkat berdasarkan Single Pollution Index (Pi), Contamination Factor (CF), of Geoaccumulation (Igeo), Bioaccumulation (BAF), Estimated Daily Intake (ED...

Soil pollution is a highlighted concern of modern society, particularly in developing countries. The Drosh-Shishi valley, which hilly region near Afghanistan with land area around 15,000 km2, situated the south Chitral District (Pakistan) and has population approximately 450,000. Nowadays, this being explored for soil pollution, specifically heavy metals pose potential risk to human health. The...

The possible effect of contrails in modifying the weather is reconsidered in the light of information obtained from ground-level contrails in Alaska. It appears likely that inadvertent cloud seeding b y jet aircraft may be of the same order of magnitude as that attained in commercial cloud seeding operations. Further investigation is needed; but in the meantime, the possibility of contrail cont...
