Determination of chlorpropham (CIPC) residues, in the concrete flooring of potato stores, using quantitative (HPLC UV/VIS) and qualitative (GCMS) methods.

Isopropyl-N-(3-chlorophenyl) carbamate (CIPC, common name Chlorpropham) is commonly used for post-harvest sprout inhibition in stored potatoes. It is applied as a thermal fog which results in loss to the fabric of the store and the atmosphere. Recently, there have been concerns in the United Kingdom because of cross contamination of other crop commodities that were stored in buildings with a history of CIPC usage.

Nuclear reprocessing-related radiocarbon (C) uptake into UK marine mammals.

To evaluate the transfer of Sellafield-derived radiocarbon (C) to top predators in the UK marine environment, C activities were examined in stranded marine mammals. All samples of harbour porpoise (Phocoena phocoena) obtained from the Irish Sea showed C enrichment above background. Mammal samples obtained from the West of Scotland, including harbour porpoise, grey seals (Halichoerus grypus) and harbour seals (Phoca vitulina) showed C enrichment but to a lesser extent.

Ecosystem uptake and transfer of Sellafield-derived radiocarbon (C) part 2: The West of Scotland.

Ecosystem uptake and transfer of Sellafield-derived radiocarbon (C) were examined within the West of Scotland marine environment. The dissolved inorganic carbon component of seawater, enriched in C, is transported to the West of Scotland where it is transferred through the marine food web. Benthic and pelagic biota with variable life-spans living in the North Channel and Clyde Sea show comparable C activities.

Ecosystem uptake and transfer of Sellafield-derived radiocarbon (C). Part 1. The Irish Sea.

Ecosystem uptake and transfer processes of Sellafield-derived radiocarbon (C) within the Irish Sea were examined. Highly variable activities in sediment, seawater and biota indicate complex C dispersal and uptake dynamics. All east basin biota exhibited C enrichments above ambient background while most west basin biota had C activities close to background, although four organisms including two slow-moving species were significantly enriched.

Assessment of physico-chemical properties and metal contents of water and sediments of Bodo Creek, Niger Delta, Nigeria.

Some physico-chemical properties and the concentrations of the metals Fe, Mn, Ni, Cd, Cr, Co, Cu, Pb, and Zn in water and sediments were examined from September 2011 to January 2012 in Bodo Creek, where oil spills have been recurrent. Temperature, pH, total dissolved solid, conductivity, salinity, dissolved oxygen, biological oxygen demand (BOD), chemical oxygen demand (COD), total hardness, sulfate, nitrate, and phosphate were determined in surface water. Particle size, total organic matter (TOM), and pH were also determined in the sediments.

Accumulation of Sellafield-derived radiocarbon ((14)C) in Irish Sea and West of Scotland intertidal shells and sediments.

The nuclear energy industry produces radioactive waste at various stages of the fuel cycle. In the United Kingdom, spent fuel is reprocessed at the Sellafield facility in Cumbria on the North West coast of England. Waste generated at the site comprises a wide range of radionuclides including radiocarbon ((14)C) which is disposed of in various forms including highly soluble inorganic carbon within the low level liquid radioactive effluent, via pipelines into the Irish Sea.

Mobility of antimony, arsenic and lead at a former antimony mine, Glendinning, Scotland.

Unlabelled: Elevated concentrations of antimony (Sb), arsenic (As) and lead (Pb) in upland organic-rich soils have resulted from past Sb mining activities at Glendinning, southern Scotland. Transfer of these elements into soil porewaters was linked to the production and leaching of dissolved organic matter and to leaching of spoil material. Sb was predominantly present in truly dissolved (<3 kDa) forms whilst As and Pb were more commonly associated with large Fe-rich/organic colloids.

Equilibrium, kinetic and thermodynamic studies on the removal of U(VI) by low cost agricultural waste.

In this research, biosorption efficiency of different agro-wastes was evaluated with rice husk showing maximum biosorption capacity among the selected biosorbents. Optimization of native, SDS-treated and immobilized rice husk adsorption parameters including pH, biosorbent amount, contact time, initial U(VI) concentration and temperature for maximum U(VI) removal was investigated. Maximum biosorption capacity for native (29.

Phytotoxicity of branched cyclohexanes found in the volatile fraction of diesel fuel on germination of selected grass species.

During a larger study to screen candidate plant species for phytoremediation of diesel fuel-contaminated soils, it was observed that at relatively low levels of diesel fuel contamination, delayed shoot/root emergence and reduced germination was observed for the majority of plant species investigated. It was theorised that these effects were the result of acute phytotoxicity, caused by the volatile fraction of diesel fuel, with results supporting this theory. This finding was investigated further in the current study.
