DISCUSSION Lysozyme The results revealed that low concentration of cadmium significantly p≤ decreased the lysozyme content in common carp serum from ± mg mL 1 in control to ± mg mL 1 in exposed fish after 30 days while 15 days following exposure the decrease in level of lysozyme in group II was not prominent and was nearly similar to those recorded in

All the information on Cadmium Home

Home Cadmium is a minor metallic element one of the naturally occurring components in the earth s crust and waters and present everywhere in our environment It was first discovered in Germany in 1817 as a by product of the zinc refining process Its name is derived from the Latin word cadmia and the Greek word kadmeia that are ancient

How to Calculate Concentration in PPM Sciencing

Since 1 liter of water has a mass of 1 kg any concentration expressed in mg/L is already in PPM because it s equivalent to mg/kg So if you have a mixture of 132 mg/L then it s 132 PPM and you can even perform simple conversions from things like g/L to PPM by using this fact just convert the mass to mg and you re done
