Introduction
The main theme of the book is that we expose ourselves to dangerous chemicals from using common household products for cleaning and hygienic products. However, the real danger of using these chemicals is that most of our society doesn’t know the potential health effects and outcomes one is facing. Environmental health addresses all the physical, chemical and biological factors external to a person, and all the related factors impacting behaviors. It encompasses the assessment and control of those environmental factors that can potentially can affect our health.(World Health Organization). The theme of the book is relevant to environmental health because the authors are assessing their exposure to these dangerous chemicals that are found in the products that we use to continue with our daily lives. They publish their results and find that phthalates, PFOA and PCBs are both dangerous to human health and the environment.
Background
The environmental health problems described in this book are that phthalates, PFOA and PCBs are dangerous chemicals. We are exposed to these chemicals on a daily basis and they are common household products and hygienic products. We are also increasing our exposure levels, which can create negative health effects and affect our environment. The magnitude of the problem is enormous. Everybody uses and are exposed these products on a daily basis.
Phthalates are found in plastic materials. They can cause endocrine disruption, in other words it can affect our hormones. They can also cause damage in the environment. It can harm marine life since we don’t properly recycle throw away plastic materials. PFOA (perfluoroctanoic acid) is a carcinogen. Studies show that it can cause pancreatic canc...

The premise of Theo Colborns’ research was to find the connection between the rising incidences of cancer and environmental contamination in the Great Lakes region. However, during field and laboratory studies, Colborn discovered that there was no direct link between the contamination and cancer. However, Colborn did find reoccurring patterns of abnormal behavior and deformed offspring amongst the wildlife populations in the Great Lakes region. Elevated levels of polychlorinated biphenls (PCBs), pesticides dieldrin, DDT, lindane and chlordane were found during tissue analysis of the wildlife in the Great Lakes region (Colborn et. Al 1996). These elevated levels were found in offspring of the wildlife who appeared to be healthy. This supported Colborns’ hypothesis that these contaminations disrupt hormones produced by the endocrine system during growth and development, which will then cause physical and behavioral abnormalities in the fetus.
In 2010, there was a huge oil spill near the Gulf of Mexico that we now know as the BP Oil Spill today. The Spill sent about 170 million barrels of crude oil into the Gulf of Mexico. The spill killed 11 men aboard the deep-water Horizon. The BP Oil Spill impacted the environment very negatively. There were different types of environmental impact as a result of the Oil Spill, but the two that grabbed my attention the most are the Polluted Air and the Contaminated Food Chain. The first impact that grabbed my attention was the Polluted Air. Because of the Oil Spill, the air around the surroundings neighborhoods was polluted. All the lightest chemicals in the oil that had spill evaporated within hours of the incidence forming air pollution particles. These particles that are in the air poses significant threats to the human health from being inhaled. The chemical found in the particles that was formed is known as Volatile, which has been known to cause respiratory irritation and central nervous system depression (Solomon & Janssen, 2010). The second impact that grabbed my attention was the contamination of the food chain, specifically the food chain of sea animals that lives near the Gulf of Mexico. Scientists found traces of oil in zooplanktons; this could only mean that the sea creature has had contact with the spilled oil. According to the Staff at Houston Business Journal (2012), “Baby fish and shrimp feed on the tiny, drifting zooplankton, and then introduce contamination and pollution to the larger sea creatures in the food web.” With these findings, it isn’t going to take long before the baby fishes become grown and caught by fishermen and before we know it, it’s on our dinner plate. And here we are eating fishes w...
Environmental Hormone Mimics and Their Serious Health Threats Chemicals affecting human health have been a problem for the past years and have still been a growing problem for our society. Issue 10 is concerned about this problem. It is pointing out the major harms and the reasons for this problem. First, it is talking about the argument that is against these chemicals. After this, an argument that says these specific chemicals do not necessarily have an affect in human health is discussed.

Chemical pollution into the environment can cause both genotypic and phenotypic changes in many organisms, including humans. More specifically, environmental pollutants like BPA can act as xenoestrogens (estrogen imitators), ultimately affecting hormonal activity and production in an organism. This alteration in activity and production can be termed as endocrine disruption. The endocrine system regulates a variety of processes responsible for growth and development, including gonadal formation and function, digestion, metabolism, sex differentiation, and embryonic development (reviewed by Flint et al., 2012). Chemicals that interfere with the function or structure of the endocrine system can be defined as endocrine disrupting compounds (EDCs) (US Environmental Protection Agency, 2007).
As cited by Environmental Protection Agency (EPA) of US, Pb and Pb containing compounds is one of the top 17 chemicals causing greatest threat to human life and environment.1st July 2006 has been official...
During recent years, numerous newspaper and magazine articles have suggested that humans may be at risk because small amounts of well known environmental contaminants, such as dioxin, PCBs and DDT, can affect hormone levels. Hormones are produced by the endocrine system as regulators of biological function in target organs. Because hormones play a critical role in early development, toxicological effects on the endocrine system often have an impact on the reproductive system. The term endocrine disruptor is used to describe chemicals that can mimic hormones and may either enhance or counteract their effects. It has been suggested that these hormone changes can, in turn, lead to a variety of health problems including cancer, decreased fertility, and abnormalities in newborns.
Recently, an uninhabited island in the South Pacific Ocean was found to be polluted with 38 million pieces of plastic that had been carried over by currents (Wang, “No one lives on this remote Pacific island”). The island, dubbed ‘trash island’, is home to diverse animal populations that have all been devastated by the pollution. On the beach, hundreds of birds were seen dead by reporters and scientists. When analyzed, the primary cause of death turned out to be consumption of plastic. When animals ingest plastic, it clogs their stomach and poisons their body with toxic chemicals. These toxic chemicals cause an array of issues, such as reproductive and endocrine problems. Eventually, this leads to death (Knoblauch, “The environmental toll of plastics”). But due to the nature of plastics, it can take hundreds or even thousands of years to completely degrade, meaning that as plastic pollution continues to build up, more places like ‘trash island’ will be discovered. According to conservation scientist Alex Bond, “…[The island] is just an indicator of what’s floating around out there” (Wang, “No one lives on this remote Pacific
The US Container Recycling Institute estimates that 67 million plastic water bottles are discarded every day, which is enough to wrap around the planet 149 times each year. Therefore, plastic water bottles should be banned from public use. The usage of water bottles should be suppressed because they are incredibly dangerous, wasteful, expensive, and rarely recycled. Researchers have stated that plastic bottles containing water can contain many harmful chemicals. After close examination of the plastic, researchers have concluded that some plastics contain chemicals, such as phthalates, bisphenol A (BPA), endocrine disruptors, and carcinogens, which may leach into the water, especially after being stagnant for long periods of time.
An example of an additive is di-butyl phthalate and biphenyl A (BPA), these substances are incorporated while the plastics are being manufactured to provide tensile flexibility and tensile strength. The microplastics tend to accumulate and adsorb toxic materials from the seawater around them, such as organic pollutants and heavy metals. The chemicals are not bound to the microplastic surface, and as a result, when ingested they tend to leach into the animal tissues (Do Sul, J. A. I, 2014). The impacts from such chemical leaches include hepatic stress in fish, mortality, and endocrine

Contamination of Water and Air. Urbanization enhances the proliferation of industries, automobiles, and agricultural practices. Most toxic air contaminants are produced as we endeavor to fuel our homes, automobiles, factories, energy production facilities, and might also be discovered in indoor cleansing mixtures, and construction supplies. Furthermore pollutants found in gasoline, dry cleaning services, and paint thinners and strippers; som...
Although companies across the globe continue to produce multiple polycarbonate #7 plastic products with BPA, more is being noticed about the adverse health effects to humans can be harmful. Testing on mice has proven that some exposure to BPA can be linked to Cancer and neurological disorders. In countries which have banned the use of BPA in different products, would agree that this chemical is toxic and dangerous. However, as long countries like the United States, who do not currently support banning BPA countrywide due to limited scientific data to back all claims, BPA will continue to be a global issue which continues to be hidden in the dark and a mystery globally
Some examples of harmful toxins with difficult names include diethanolamine (DEA), formaldehyde, glucocorticoids, and triethanolamine (TEA). We are exposed to toxic chemicals in many ways. We may breathe them in as sprays and powders, swallow chemicals on our lips and, even rub them on our skin. According to a team of researchers who conducted a study on the relationship between exposure to phthalates and DNA damage on human sperm, “cosmetics frequently contain enhancers that allow ingredients to penetrate deeper into the skin. Studies have found health problems in people exposed to common fragrance and sunscreen ingredients, including increased risk of sperm damage, feminization of the male reproductive system and low birth weight in girls” (Duty et al. 1164). There should be regulations banning toxic chemicals from personal care and beauty products because toxins are bad for our health (1), the consumer faith in cosmetic companies are suffering (2), and other countries recognized the effects and banned it while America has not
These fragments absorb all the toxins that pollute waterways, contaminate soil, and sicken animals (which are then consumed). Plastic trash also absorbs organic pollutants such as BPA. They take centuries to decompose while sitting in landfills, amounting to billions of environmentally poisonous time bombs. Bisphenol A (BPA) is a chemical compound used to create polycarbonate plastic and epoxy resins. Polycarbonate plastics are found in a wide range of products, but food and drink containers are the most concerning.
