i am an environmental science student and i have conducted a practical
section on studying lead intoxication by measuring the zinc protoporphyrin
and protoporphyrin content in the blood. i have some problems about this
practical:
1. i observed no difference between the control sample and lead intoxicated
specimens. what's wrong with my result?
2. how can i differentiate the test subjects suffering from chronic or
acute lead-poisoning from my results?
3.what are the pros and cons of using dried blood over liquid whole blood
for testing?
4. can i perform simultaneous measurement of ZnPP and PP in the same HPLC
run?
i hope someone would help me to solve this problems. are there any
references which would help?
thank you
