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 as mentioned in
the article that “low levels of drugs such as antibiotics, hormones,
contraceptives and steroids are found in 80% of the rivers and streams”. Due to
this, these water sources are unsafe for consumption and usage. At the same
time, it harms the marine and human life 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 fishes were found laying eggs due to prolonged exposure to
such residue. Legislation and raising public awareness on the proper disposal
of pharmaceutical waste have been put in place to mitigate the problem. The
same author explains the cause and impact of pharmaceutical waste disposal with
a myriad of examples. However, the statements he put forth in the article are
incomplete and unsupported. For example, there was a lack of data to the
quantity of pharmaceutical effluent present in the water sources and the same
author did not consider other possible environmental factors that contribute to
genetic mutation seen in marine life. Furthermore, Iburch did not introduce the
safe methods for pharmaceutical waste disposal that is approved by regulatory
bodies for the different classes of drugs too.
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, which do not exhibit anti-infective or anti-neoplastic
properties, can be flushed down into the sewers. Iburch also fails to elaborate
on how human excretion can potentially contribute to pharmaceutical waste.
Studies by the Harvard Medical School (2011) have concluded that human waste
flushed into the sewage contains unmetabolized pharmaceuticals and
this could potentially contaminate potable water sources. In addition, Iburch
did not mention anything on the root of the issue; pharmaceuticals that are
purchased in bulk were left unconsumed. This results in large amounts of
unconsumed pharmaceuticals being flushed down 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 pharmaceutical waste present in the potable
water sources is not mentioned. Iburch states the effects of the pharmaceutical
effluents have on the genetic mutation of marine life, without factoring in
some other environmental factors. Eisenstaedt (2005) argues that different
chemical compositions of water, temperature and other variables can 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 more informed conclusion that
the hormones present in the pharmaceutical effluents are responsible for the
genetic mutation seen.
In conclusion, the author carefully links the cause and effects of improper pharmaceutical waste disposal with a myriad of examples.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, the lack of concrete statistical data and over generalisation of "flushing down unused or expired pharmaceuticals into the sewage" make the arguments which Iburch put forth in the article inconclusive and unsupported.
