- Urine testing is the only approved drug testing method for workplaces covered by federal guidelines.
- Saliva testing can detect recent drug use and is efficient for onsite collection.
- Cheating on urine tests is possible but difficult.
- Hair testing is a strong deterrent for drug-using applicants.
- Hair testing is not effective for detecting sporadic drug use.
- Disulfide bonds in keratin determine hair texture.
- Redox reactions can be used to change hair texture.
- Reactions involve breaking and forming bonds.
- LEO says GER is a way to remember redox reactions.
- The oxidation number tracks electrons gained or lost in redox reactions.
- N has 8 oxidation states and O only has one.
- Oxidation is the loss of electrons.
- Reduction is the gain of electrons.
- MnO2 + 4HCl → MnCl2 + Cl2 + 2H2O is an example of a redox reaction.
- Oxidation involves an increase in atoms.
- Reduction involves a decrease in atoms.
- Breaking certain bonds in keratin molecules can impact the structure of hair.
