After an animal or a human has ingested any type of pill or prescription drug, all of the components of the drug aare not completely absorbed. The remains of these drugs are excreted and are now showing up in ground water, soil, waterways and even drinking water. The reaosn for this is because our ocnventional sewage systems are not finding these duges, or even looking for them. Another cause of this pharmaceutical pollution is when people flush excess pills down the toilet, as they ultimately end up somewhere in our environment. This form of pollution has massive impacts on agriculture, wildlife, and humans. almost eighty percent of streams in the united states contain contaiminents such as antibiotics, steroids, synthetic hormones or any other common drugs. About half of the streams contained seven or more compounds, one water sampls alone, contained 38 different types of chemicals, and one third of the streamscontained ten or more compounds. Many drugs are ingested in the united states and about ninety percent of these are excreted back out of the body into the sewere system and essentially in our environment. Humans alons consum 235 million doses of antibiotics yearly, and livestock and poultry farmers administer over 21 million pounds of antibiotics to animals in the year 2004. These drugs do not only affect the health of humans but also animals who feed on thier natural surroundings. In conclusion, Pharmaceutical distribution and waste management has a great impact on our society and our environment especially in the health aspects.
