On the website, “Citizen Campaign for the Environment”, Iburch
(2015) reports on the adverse impact that improper pharmaceutical waste
disposal has on the environment. Improper pharmaceutical waste disposal
contaminates potable water sources, and it is mentioned by the same author that
“low levels of drugs such as antibiotics, hormones, contraceptives and steroids
are found in 80% of the rivers and streams”. Thus, these water sources are
unsafe for consumption and usage. At the same time, it harms the marine life
and humans by leaving them vulnerable to such pharmaceutical waste residue,
albeit at low concentration. Some side effects on living organisms include
irregular hormonal cycle and antibiotic resistance to drugs. Notably, male fish
were found laying eggs due to prolong exposure to such residue. Legislation and raising public awareness on the
proper disposal of pharmaceutical waste have been put in place to mitigate
these prevailing issue.
In Iburch’s article, there is a lack of data to the quantity of
pharmaceutical effluent present in the water sources that causes the
detrimental side effects observed in living organisms. In addition, Iburch did
not consider other possible environmental factors that contributes to genetic
mutation seen in marine life.The same author did not introduce the safe methods
for pharmaceutical waste disposal that is approved by regulatory bodies for the
different classes of drugs too. Thus, this makes his statements put forth
incomplete and unsupported.
The first reason why Iburch’s argument is incomplete is because he
over generalises the idea of “unused or expired pharmaceuticals being flushed
down the toilet”. According to a pharmaceutical waste disposal
guideline that was released by the World Health Organization (1999), it states
that small amounts of uncontrolled liquid pharmaceuticals that doesn’t exhibit
anti-infective or anti-neoplastic properties can be flush down into the sewers.
Iburch also fails to elobrate on how human excretion can potentially contribute
to pharmaceutical waste.Harvard University (2015), concludes that human waste
flushed into the sewage contains unmetabolized drugs, and could potentially
contaminate potable water sources.In addition, Iburch didn’t mention anything
on the root of the issue- unconsumed pharmaceutics purchased in bulk.
This is the main reason to huge amounts of unused pharmaceutics being flushed
down, along with others into the sewage.
Furthermore, the examples
used to illustrate the detrimental effects of pharmaceutical waste have on
living organisms are not convincing due to the lack of statistical data .For instance,the
concentration of hormones in the effluents is not mentioned. Besides, Iburch
talks about the effects of the pharmaceutical effluent have on genetic mutation of
marine life, without factoring in some of the environmental factors.Eisenstadt(2005)studies the different chemical compositions of
water,temperature and other variables that could potentially explain the
genetic mutation seen in marine life.The lack of concrete data and research
makes it hard for readers to come to a conclusion, that the hormones present in
the pharmaceutical effluents are responsible for genetic mutation seen.
In conclusion, the author carefully links the cause and effects of
improper pharmaceutical waste disposal with a myriad of examples.
However, it would be better if the author addresses the issue in a broader
perspective, before moving into smaller details. This would give the reader a
general overview of the issue. Lastly, it is inevitable that pharmaceutical
waste is contaminating our potable water sources. It is a problem where
attention needs to be directed to.
