Concentrations in dried pellets were similar to the dewatered sludge , but were reduced in composted sludge due to the addition of wood chips. Only Mo exceeded USEPA §503 exceptional quality (EQ) limits in these three products.

Copper Chaperone Antioxidant Protein1 Is Essential for Copper

Copper is essential for plant growth but toxic in excess.Specific molecular mechanisms maintain Cu homeostasis to facilitate its use and avoid the toxicity. Cu chaperones, proteins containing a Cu-binding domain(s), are thought to assist Cu intracellular homeostasis by their Cu-chelating ability.In Arabidopsis (Arabidopsis thaliana), two Cu chaperones, Antioxidant Protein1 (ATX1)

A screening study of elemental composition in 12 marketable

Cultivated mushroom species are becoming an increasingly consumed commodity owing to their nutritional value and potential biological activities. There is a strict necessity to conduct a thorough screening of their chemical composition to ensure the quality and safety of final food products. The present study analyzed the content of 67 macro- and microelements and

Staphylococcus aureus is one of the most important pathogens of humans and animals. Livestock production contributes a significant proportion to the South African Gross Domestic Product. Consequently, the aim of this study was to determine for the first time the prevalence, virulence, antibiotic and heavy metal resistance in livestock-associated S. aureus isolated from South African livestock

Multivariate statistical assessment of heavy metal

The contamination of groundwater by heavy metal ions around a lead and zinc plant has been studied. As a case study groundwater contamination in Bonab Industrial Estate (Zanjan-Iran) for iron, cobalt, nickel, copper, zinc, cadmium and lead content was investigated using differential pulse polarography (DPP). Although, cobalt, copper and zinc were found correspondingly in 47.8%, 100.0%, and 100

In a pot culture experiment, five different species of Brassica (Brassica juncea, Brassica campestris, Brassica carinata, Brassica napus, and Brassica nigra) were grown for screening possible accumulators of heavy metals, viz. Zn, Cu, Ni, and Pb. The plants were grown to maturity in a soil irrigated
