The present study estimated the concentration (in ppm) of heavy metals Zn, Fe, Cu and Pb in water samples edible tissue Labeo boga; both collected from non polluted (Station I) II) locations river Tawi, Jammu, India. mean (Zn, Cu, Pb) at Station I were 0.048±0.008 (ppm); 0.016±0.001 0.157±0.002 (ppm) 0.0001±0.0001 respectively; while II, these values 0.133±0.001 0.022±0.002 0.206±0.002 0.002±0....

The results of analysis of soil and tree leaves samples collected from heavy traffic affected area of Agra city show that average concentration of Cu, Fe, Ni, Pb, Mn and Zn ranged from 0.953.42, 3.2811.26, 2.18-4.05, 3.04-8.10, 0.91-1.42 and 2.83-5.94 ppm , respectively in soil samples. The maximum concentration of Ni (2.68ppm) and Co (4.82 ppm) was observed in the leaves of Ficus religiosa and...

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...

BACKGROUND Hoof lesions are very common among sows and have been associated with lameness, early removal and compromised welfare and productivity. Although housing conditions and management can have an external effect on hoof health status, the role of trace mineral intake is vital in developing hoof structure and integrity. Therefore, the objective of this study was to investigate the effect o...

This study was conducted to examine whether Cu could exert its growth-promoting effect when injected, rather than being fed, and thus bypass the gastrointestinal tract. In two 18-d experiments, pigs were injected every 2 d with a Cu histidinate or histidine solution. Amounts of Cu injected were calculated to simulate varying absorption rates in pigs fed 250 ppm of dietary Cu. In Exp. 1, 44 pigs...

Abstract This paper describes the demonstration of a series heterobimetallic, isoreticular 2D conductive metal–organic frameworks (MOFs) with metallophthalocyanine (MPc, M=Co and Ni) units interconnected by Cu nodes towards low‐power chemiresistive sensing ppm levels carbon monoxide (CO). Devices achieve sub‐part‐per‐million (ppm) limit detection (LOD) 0.53 toward CO at low driving voltage 0.1 ...

Lemon balm (Melissa officinalis L.), a member of Lamiaceae family, is an important medicinal plant that has many useful properties. Micronutrients are necessary in low dose for the growth and the development of plants. Present research was conducted to study the effects of micronutrients including manganese (Mn) and copper (Cu) on morpho-physiological traits and essential oil of lemon balm. Fie...

The hydrogen permeance of several 0.1 mm thick Pd–Cu alloy foils (80 wt.% Pd–20 wt.% Cu, 60 wt.% Pd–40 wt.% Cu and 53 wt.% Pd–47 wt.% Cu) was evaluated using transient flux measurements at temperatures ranging from 603 to 1123 K and pressures up to 620 kPa both in the presence and absence of 1000 ppm H2S. Sulfur resistance, as evidenced by no significant change in permeance, was correlated with...
