our environment and health. One of the greatest dangers we face today is the groundwater pollution from lacheates. While they are supposed to protect humans from harmful toxins‚ but these protective barriers only delay the inevitable due to natural deterioration. The problem with landfills lacheates is the leakage of many toxins. Since landfills are usually built near large bodies of water‚ this pollution often goes undetected. Frequent seeping of metals and organic compounds submerge themselves

However‚ as humans began to understand more fields in chemistry‚ biology‚ and technology‚ our bodies also become more exposed to toxins brought about by chemicals in the food we eat‚ radiation from the things we use‚ and pollutions in the air we breathe. Our bodies become so overwhelmed by the sudden increase in the toxins that surround our environment that it impairs our ability to quickly adapt to what we are experiencing. As a result‚ we become a little less healthy by day

Biochemistry Introduction DNA is a double-stranded molecule of polynucleotide chains twined/twisted together into a double helix structure. This molecule is the one that forms the genetic material responsible for transfer hereditary genetic information from one cell to another during cell division. RNA is a single-stranded molecule that contains polynucleotide chain used for the transfer of genetic information especially in bacteria cells (Freifelder‚ 2002).

Pesticides dropped from the air over fields (like crop dusting) can easily drift if there is even just a slight wind. The chemicals that are sprayed on the ground‚ even household weed killers‚ have a tendency to wash into local streams and rivers with the first rain. This has caused many incidents of fish‚ numerous miles down a river‚ to be found dead due to the toxins in the

These toxins may be contaminated in animal tissues and they create the risk for people who consume them. There are also indirect effects caused by these farms.

Toxicological Chemistry - relates the aspects of toxicology to the chemical structure and reactivity of the toxin. It is concerned with the chemical interaction of the toxin with the receptor that gives the physiological response. The ultimate aim is to relate functional group chemistry of both toxin and receptor to the interaction Toxicity - the degree to which a substance causes damage to an organism Acute toxicity - the adverse effects resulting from a single exposure‚ or exposure over
