Endocrine Disruptors Report

In this experiment, contractions of the earthworm gut are measured in an organ bath with a force transducer. The effect of neurotransmitters and ionic concentrations on contraction strength and rate will be investigated.

*Endocrine glands produce – hormones, they work with other hormones to perform many functions including: control water & electrolyte balance, regulating carbohydrate metabolism, working as neurotransmitters, maintaining stress & inflammation, regulate reproductive functions

The decisions that Gina McCarthy, the Administrator of the U.S. Environmental Protection Agency, makes have a direct impact on the health of the nation. Gina and her agency ensure the safety and cleanliness of the environment through standard setting, monitoring levels of chemicals and pollutants, and making sure these standards are enforced throughout all levels of industry. One group of industrial chemicals that have been receiving attention recently are the environmental endocrine disrupters (EED), such as DDT and Bispehnol A, that can be found in a wide range of products that Americans use in their everyday life. From household cleaners, food and beverage containers, beauty products, and even children’s toys, these chemicals are widely

The endocrine system is a very important part of the anatomy and physiology of the human body. Knowing and understanding how this system operates and what contributes to its failures can be helpful in understanding how the body contributes to overall health and wellness. The purpose of this essay is to highlight and describe the adreanal glands, an important component of the endocrine system. In this analysis, this essay will describe the location and normal physiology of the adrenal glands and discuss the hormones that are associated with this part of the body. Also the feedback mechanisms and communication system within the group of endocrine glands will be discussed. Finally a malfunction of the adrenal glands will also be introduced to highlight how disease and illness can negatively impact the endocrine system and the human body's means of healing.

Chemicals harm the growth of plants and animals, chemicals can lead animals to death. Many of the water animals

A critical area of concern for gynecologists, obstetricians, and other reproductive health officials is how to reduce the exposure to toxic environmental agents to both the mother and developing fetus. Exposure to these chemicals is ubiquitious and the long lasting effects on the reproductive health throughout an individuals life span, which is evident when exposure occurs prior to conception and during fetal gestation. Patient exposure to manufacture and use of industrial chemicals is a critical concern, since there is constant introduction of new chemicals each year and more than 84,000 chemical substances are current listed by the Environmental Protection Agency. Unlike pharmaceuticals, environmental chemicals do

It has been a mystery for hundreds of years and it has puzzled many historians and archaeologist. They wonder what happened to the lost colony of Roanoke did they die because of war or something they all ate? What people are trying to find out is what was the reason for the people disappearing years after arriving. Why Do you think they wanted to come to America? The main reason for them coming to “America” was Queen Elizabeth 1st wanted to establish an English settlement on the new land.

There is no scientific proof done by researchers to provide any evidence the chemical might do harm, but there isn’t any research that says it does no harm with exposure overtime. The precautionary principle relies on our history with asbestos, PCB, and chlorofluorocarbons destroying the ozone. Therefore, a strength in the precautionary principle is the research it acquires in order to provide enough evidence a chemical like DDT can become more harmful than beneficial. However, the precautionary principle is only based on skepticism and not actual data found from trials in research. The precautionary principle has the capacity to save lives by reducing the human race and planet Earth from being exposed to dangerous chemicals. However, the implications of using the precautionary principle can lead to several deaths to diseases like West Nile Virus and Malaria because of the DDT ban based on skepticism and history

The above research shows that endocrine disruptors may pose the greatest risk during prenatal and early postnatal development when organ and neural systems are developing. Additionally, the consequences in animals linked to early exposure may not be apparent until later in life, but EDC’s can affect subfertility, premature reproductive senescence, and cancer. These issues are our greatest concern, and alternative precautionary strategies must be adopted, which including seeking to eliminate or minimize unnecessary risks to the fetus, even in the absence of clear proof of harm. Some of these steps can be taken by individuals, such as lifestyle changes in women who are pregnant, and reducing exposures through the release of chemicals to the environment. However, clinicians and scientist must educate law officials and the public about the threats of endocrine disruptors in order to adverse the trends of disease and destruction throughout the

The Great Lakes, though fairly clean, are contaminated with some deadly chemicals that have slipped by human filtration into the lakes. These emerging chemicals have been determined to pose some health risk to humans and surrounding ecosystems and are used by society, but are unregulated or inadequately regulated retardants (Miller-Branovacki, Lindsay, "Water Resources and Urban Waste Water (Week #8)"). More specifically an emerging contaminant is one which is not historically widely distributed, nor a concern, however are now persistent and bioaccumulative making them a concern for the environment. The three major categories for emerging contaminants are; endocrine disrupting compounds (EDCs), Pharmaceutical and personal care

The endocrine system is a group of glands distributed throughout the human body. This group of glands secretes substances called hormones. These hormones are dumping into the bloodstream (Shier, Butler & Lewis, 2009). The endocrine system does not have a single anatomic location. It is dispersed throughout the human body. The final purpose of this process is to control, regulate, and coordinate the functioning of the human body. Some body functions can be activated or inhibited by hormones, which are secreted in very small quantities. The hormone related diseases may be due to hyper secretion, or a hypo secretion. The hormones secreted by the endocrine glands regulate growth, development and function of many tissues, and coordinate the

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

"Sucking the life out of someone " means to me is that someone is draining someone's energy out and making them very tired. But according to V, Bee it means " That you’re a joy sucker.You suck their energy, their happiness and their enthusiasm." Most people would not just say you’re a joy sucker to your face instead they will use this phrase to make it sound better then using joy sucker. This phrase is mostly used to people who take away happiness and that are not having fun while other people are trying to have fun and this person is bringing them

This paper explores three published articles that reflect the findings from studies conducted to examine the relationships between environmental hormone mimics (endocrine disruptors) and their effect on the human body. This paper specifically discusses three key environmental hormone mimics: bisphenol-A, dioxins, and pesticides. Each of the three studies links the chosen environmental hormone mimic to abnormalities caused by exposure to the chemicals. Bisphenol-A is linked directly to altering estrogen levels in women. The consequences are carried onto the child if the carrying mother ingests BPA while pregnant. Dioxins are extremely harmful and cannot be disposed of easily despite the amount of land, money, and clean up efforts that are taken. Pesticides simply from working in fields or by eating fruits and vegetables are very harmful in men. A male’s reproductive system is directly impaired as sperm counts drop dramatically and abnormalities effecting sperm size and shape occur.

Although the state of America’s water infrastructure is of great concern, the types of chemicals found in America’s tap water are equally as frightening. The passage of the Water Act in 1972 prevents the direct dumping of hazardous chemicals directly into waterways, and helps regulate quality standards of water. However, the Clean Water Act is has no jurisdiction on regulating indirect dumping of chemicals that integrates into water supplies. Pesticides and prescription drugs are the greatest cause for concern of indirect containments in America’s water supply (Olsen). An abundance of the harmful chemicals found in liquefied animals feces, used in large dairy states, have percolated into drinking wells that have caused serious infections (Duhigg). However, more harmful containments are infiltrating water supplies. Such containments include
