20. Benzene is classified by ACGIH as an A1 carcinogen. Based upon what you know about the biotransformation of benzene, would you expect benzene to be a procarcinogen? Toluene is not classified as A1. Why do you think there might be a difference between the way the body metabolizes benzene and

As a positively charged ion, methyl mercury combines with anions, such as chloride (Cl-), nitrate (NO3-), hydroxide (OH-), and sulphur containing anions, such as thio groups (SH). Indeed, the thio group on the amino acid cysteine and hence in proteins containing cysteine has high affinity for methyl mercury forming a strong covalent bond.

This is the protein that carries oxygen in the blood. What sometimes happens is that genetic mutation causes the amino acids in this enzyme to change, and this change lessens the movement of this enzyme in the body, due to which the human body experiences high toxic levels.

One of the dyes that were being sought for in the experiment was Sudan dyes. These are synthetic azo dyes commonly in industries despite the fact that they have been found to be contaminating foodstuffs (Juan Lia et al. 2013). This paper could have informed its readers more
Toxicology is the study of toxicity and it covers all biological organizations. It embraces concepts from other scientific subjects to measure the degree of exposure as well as the modes of prevention. There are number of
