Believe it or not, but pharmaceuticals, as helpful as they
are to human health ... are quickly invading the environment around us with
harmful effects.
Personal care products such as hair dyes and more are also
having a negative impact as they leave houses and businesses and enter the
environment.
From 1999 to 2002, the United States Geological Survey
(USGS) studied surface and groundwater samples
from around the country to determine whether PPCPs were present.
The most commonly found compounds were: steroids, OTC
medications (like ibuprofen), and insect repellants.
Different PPCPs have different toxilogical effects.
Regulatory agencies at all levels of government are
realizing that pharmaceutical and personal care products (PPCPs) and endocrine
disrupting chemicals (EDCs) in surface and drinking water are of concern.
PPCPs and EDCs are being found in rivers, lakes, and
groundwater, all which serve as sources of drinking water, and even in treated
drinking water.
PPCPs include over-the-counter (OTC) medications,
prescription medications, dietary supplements, hormones, cleaning agents
(especially antibacterial cleaners), and the inert ingredients that are
associated with these products (which can be just as harmful, if not more so,
than the active ingredients themselves).
Many of the PPCPs are actually designed to impact the human
hormone system.
Some
PPCPs are also Endocrine Disrupting Chemicals (EDCs).
The
endocrine system is a complex network of hormones and glands which release
hormones into the body and regulate growth, development and maturation.
Endocrine disrupters
are synthetic chemicals which either block or mimic
natural hormones, which in turn disrupt normal functioning of organs.
Many of the components of OTC drugs, supplements, and
prescription medications are not completely metabolized by the human body.
Therefore, the unmetabolized portions of these compounds are
excreted when people defecate or urinate. For example, when amoxicillin, a
common antibiotic,
is ingested, 60% of the drug comes out unchanged in the urine.
The PPCPs triclosan and
tricloscarban1 have been found to disrupt development in frogs, causes
endocrine disruption in mussels, disrupts thyroid hormones in rats after only
short-term exposure (Crofton, et al., Short term in Vivo exposure to the water
contaminant triclosan: Evidence for disruption of thyroxine.)
Triclosan and triclocarban are toxic to aquatic biota,
bioaccumulate in algae and earthworms, are endocrine disrupters, can contain
dioxin and other carcinogens, degrade to form other carcinogens,
and are persistent in the environment.
Many of the PPCPs are actually designed to impact the human
hormone system.

But the damage from pharmaceuticals and PPCP contamination
does not just affect the environment.
Take this one research stat for an eye-opening example;
potential human health impacts include: cancer, Type II diabetes, behavioral
changes such as increased aggressiveness and decreased attention span,
compromised immunity, and neurological effects (Spano, T., "Contaminants of
Emerging Concern: Endocrine Disrupters," Presentation to COG Chief
Administrative Officers Committee, August 1, 2007).

Clearly mankind needs to become more attentive not only to
reasons we ingest pharmaceuticals and use PPCP's, but also to the reverse
effects chemicals are having as we discard them into our environment.
