The present study has been conducted to assess the surface water quality of Halda River from September 2015 to March 2016. DO, BOD5, COD, pH, EC, Chloride, Alkalinity, and Hardness concentrations in water samples have been found to range within 0.93-5.15 mg/L, 30-545 mg/L, 43-983 mg/L, 6.3-7.3, 110-524 uS/cm, 12-56 mg/L, 35-67 mg/L, and 38-121 mg/L, respectively. Multivariate statistical analys...

Arsenic contamination of drinking water is a global problem that will likely become more apparent in future years as scientists and engineers measure the true extent of the problem. Arsenic poisoning is preventable though as there are several methods for easily removing even trace amounts of arsenic from drinking water. In the present study, electrocoagulation was evaluated as a treatment techn...

In Greece and Turkey, okra (Hibiscus esculentus L.) is cultivated for small pods (≤4-5 cm), which are highly perishable after harvest. In this experiment, okra was cultivated at 4 levels of N (30, 150, 300 and 450 mg l-1) within the irrigation water. Pod yield was highest at 300 mg l-1 N. High N increased the nitrate content and decreased dry matter without affecting pod colour (P

Organisms in aquatic environments are exposed to a number of pollutants such as pharmaceutical residues. As such, the aim of the present study is to achieve the Lethal Concentration (LC50) of Povidone-iodine (Betadine) for Cyprinus carpio. To do so, the study employs samples, weighing 4±1 [mean±SD] gr, and carries out an experiment in static condition. Based on OECD instructions, after a period...

We describe a simple "high-performance" liquid-chromatographic method for determining free 3-methoxy-4-hydroxyphenylglycol (MHPG) in plasma, with coulometric detection and with 4-methoxy-3-hydroxyphenylglycol (iso-MHPG) as the internal standard. MHPG and iso-MHPG are extracted from plasma into ethyl acetate and the extract is washed with a sodium bicarbonate solution, evaporated, reconstituted,...
