Abstract AR
تضمن البحث دراسة تأثير الأحماض الدبالية و عسرة المياه على سمية الكادميوم الحادة باستخدام Simocephalus exspinosus كمؤشر حيوي و كانت قيمة التركيز المتوسط المميت LC50 بعد 48 ساعة من التعرض (2.5) ملغم \ لتر، و أدى استخدام ثلاث تراكيز من الأحماض الدبالية (100, AND 75, 50) ملغم \ لتر إلى خفض سمية الكادميوم الحادة معنويا و أن تأثيرها يزداد بزيادة التركيز، كما أدى استخدام مياه عسره و متوسطة العسرة إلى انخفاض معنوي في سمية الكادميوم الحادة.
Abstract EN
This paper was based on study the effect of humic acid and water hardness on acute cadmium toxicity by using Simocephalus exspinosus as a bio indicator.
The toxicities were expressed by the median lethal concentration (LC50), and the LC50value for (48-h) of cadmium was 2.5 mg / L.
Three concentrations of humic acid were used (50, 75 and 100) mg \ l, the acute cadmium toxicity significantly decreased by increasing humic acid concentration.
An increased in water hardness (75 and 100) mg \ l CaCO3 considered as (moderate hardness and hard) respectively also significantly decreased acute toxicity of cadmium.
