Running Head: Toxicology Toxicology Inserts His/her The ALAD gene provides instructions for making an enzyme known asdelta-aminolevulinate dehydratase, which is important in the production of “heme”. Heme is a molecule that is necessary for all of the body's organs, as it is a crucial part of quite a few iron-containing proteins, which also includes hemoglobin (McGuire & Beerman, 2009). 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.

The ALAD gene may pose the danger of developing lead poisoning in humans, those who were exposed to ecological lead. Lead is a metal that takes on toxic properties, when someone inhales it or digests it. There are several lead exposure routes, from which any human can inhale or digest lead. Several health problems are associated with lead poisoning. They include; exposure where one has to work in an environment or facility that manufacture lead-containing products; lead paint which is usually indigested by young children as they tend to try to eat non-edible things; lead content in soil, from lead-containing gasoline; sometimes lead from the soil can end up in the surface water; and those animals, which are hunted with lead-based bullets.

Problems associated with lead poisoning include issues relating to; the nervous system; kidney problems; blood; and the reproductive system of humans. References McGuire, M., & Beerman, K. A. (2009). Nutritional sciences: From fundamentals to food. Florence, KY: Brooks Cole.
