Levels of selected heavy metals (Pb, Co, Cu, Ni, Zn, Mn and Cd) in the heart and kidney tissues of parrot fish, collected from the Arabian Gulf, Eastern Province of Saudi Arabia, were determined by wetdigestion based atomic absorption method. The results showed that accumulation pattern of analyzed metals in the kidney tissues followed the order; Zn > Cu > Co > Pb > Ni > Mn > Cd. In the heart t...

The effects of dietary selenium (Se), copper (Cu) and zinc (Zn) on growth characteristics, selected blood parameters and carcass traits in growing-finishing swine were evaluated in two experiments. In the first experiment, 48 Duroc barrows and gilts weighing approximately 30 kg were al lot ted by sex and weight to six dietary treatments. They were fed a basal 16% crude protein diet containing ....

this study was conducted to determine the effects of different levels and sources of copper supplementation on hematological values, ceruloplasmin and plasma copper, zinc and iron status in mehraban male lambs. twenty growing lambs were randomly allotted to four different treatments. treatments consisted of 1) 10 mg/kg cu in the form of cuso4, 2) 20 mg/kg cu in the form of cuso4, 3) 10 mg/kg cu...

The antimicrobial properties of copper have been recognized for several years; applying these properties to the prevention of diseases such as bovine mastitis is a new area of research. The aim of the present study was to evaluate in vitro the antimicrobial activity of copper on bacteria isolated from subclinical and clinical mastitis milk samples from two regions in Chile. A total of 327 micro...

A single Brachionus rotifer can consume thousands of algae cells per hour causing an algae pond to crash within days of infection. Thus, there is a great need to reduce rotifers in order for algal biofuel production to become reality. Copper can selectively inhibit rotifers in algae ponds, thereby protecting the algae crop. Differential toxicity tests were conducted to compare the copper sensit...

In the present study, heavy metal pollution and accumulation was investigated in an important mangrove plant, Avicennia officinalis grown in the polluted sites of Kanjurmarg creek, Mumbai. This creek is a location of discharge of influent and waste of some domestic industries. The analysis was done in leaves and stem of the plant as well as in water and soil for the heavy metals like Zinc ( Zn)...

Contents of inorganic elements are very important traits in plants. Some of elements have causal effects on plant growth. Their effects on plant metabolism and therefore quality and quantity of essential oils is crucial. Thus, to obtain relatively good results, different parts of Rosa damascena Mill. genotypes were analyzed. Plants were collected from different provinces including Tehran, East ...

Cassava is a staple mostly eaten in the form of gari, after rice in Liberia. The local method of gari processing often leads to product contamination, thus, a study was done to assess the heavy metals and microbial contamination of gari in eight counties of the country. A total of sixty-one gari samples were collected and packaged in an airtight polyethylene bag for analyses, using standard met...
