Introduction Hexachlorocyclohexane’s (HCH) are primarily used as insecticides. These pollutants have been dispersed worldwide and are extremely persistent in the environment (Walker et al. 1999). HCH’s occur in eight different isomers, one of these isomers is lindane, which is also known as gamma-hexachlorocyclohexane (Willett et al. 1998). Today most of the use of HCH is in the form of lindane, but there is great concern that this isomer can be transformed into other isomers that have a greater persistence in the environment and more harmful effects to humans and other species (Walker et al. 1999). HCH’s have a very high volatility enabling them to be transported globally, even to remote locations far away from the area of application (Walker et al. 1999; Willett et al. 1998). Lindane is the only isomer with specific insecticide properties, so since the 1950’s it started to become isolated for agricultural purposes (Vijgen et al. 2011). Lindane has been used in the past for insect control in grain, fruit, and vegetable crops. It has also been used for seed treatment (Walker et al. 1999). Lindane is a suspected carcinogen, it is persistent, bioaccumulative, and has endocrine disrupting properties, causing lindane to become a banned substance in many countries (Vijgen et al. 2011). Lindane was also listed as a persistent organic pollutant by the Stockholm Convention in 2009 so it must be passed out and any waste or stockpiles of the chemical eliminated (Jit et al. 2011). Lindane has never been produced in Canada, an on January 1, 2005 it was de-registered for agricultural pest control uses, under the Pest Control Products Act (PCPA) (Environment Canada 2013). Lindane-based pharmaceuticals are currently produced and sold for use as a second line treatment for scabies and lice, this is under the authority of the Food and Drugs Act (FDA), but they are not widely used and there are alternatives (Environment Canada 2013; Mohebbipour et al. 2013). Hazard Identification Lindane is a persistent organic pollutant that was mainly used as an insecticide all over the globe. The agricultural use of lindane and the production of lindane are the main sources of environmental contamination (Vijgen et al. 2011). Lindane and other isomers of HCH can travel distances up to 22 000 km (Shen et al. 2005). Due to lindanes high volatility, it has the ability to vaporize and then condense. Lindane is found in many locations including the air, oceans, and in soil.
No one really knows the long-term effects of these substances, individually or in unpredictable combination, either on human health or on the health of the ecosystems upon which we, and all life, depend. The chemicals are not the same as the ones Carson indicted in Silent Spring, yet they are produced, sold, and used on an unsuspecting public by the same interconnected complex of profit-driven companies and government authorities. Carson’s words in her “Fable for Tomorrow” still apply, as if we lived in the future that she imagined: “No witchcraft, no enemy action” had produced our “stricken world. The people had done it themselves” (Carson, 1962,
The herbicide warfare used during the Vietnam War? Well, crazy fact triclosan and agent orange are compound cousins. Triclosan another harmful ingredient is a known pesticide, however, is considered an antibacterial in toothpaste. The FDA banned the antibacterial chemical from soaps. Again, it’s allowed in toothpaste. That top-selling toothpaste brand, Colgate Total claims the benefits (fights plaque and gingivitis) outweighs any risk present from the ingestion of triclosan. The world is so weird, isn’t it? Triclosan is a major component of the problem antibiotic resistance. Antibiotic resistance is when the bodies antibiotics have lost their ability to control or kill bacteria growth. In simple form, the bacteria resist the antibiotics and continue to multiply. The dangers of triclosan over the years have shown evidence of its negative effects on humans. Hormonal problems, allergies, and even cancer. Studies have shown that triclosan alters testosterone and thyroid serum levels, estrogen adapters and synthesis. Triclosan stores itself in Breast milk and blood which could lead to long-term effects that could potentially be passed along, affecting immune system health, fertility and
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.
Every year millions of American’s purchase chemicals intended to clean their home, remove weeds from lawns, and promise to eradicate various insects and other household pests. It is a deadly love affair with scientific advancements to create larger crops, more appealing food items and the promise of cleaner environments. Yet until recent years and the noticeable focus on organic and natural foods, very few have questioned these advancements. Rachel Carson was one of the people who had the courage and determination to stand up and question just how healthy these new advancements truly were for living creatures. Mrs. Carson’s effort to bring these things to light in her most well-known book, Silver Spring, a book that exposed just how dangerous the chemical dichlorodiphenyltrichloroethane (DDT) and other synthetic chemicals was to the environment, animals, and humans. There was much more to her efforts and her concerns than just her coverage of DDT. Through her valiant devotion, Rachel Carson’s work lives on and the world is wiser to the potential hazards associated with scientific chemical advancements. Her life and her work is a reminder that the human populace is not lone entities on this planet.

A question commonly associated with the word insecticides is, what are they? Well I have the answer, insecticides are chemicals that are used to eliminate insects. In the agricultural industry, insecticides are classified into different categories,and the most used is carcinogenic. A carcinogenic insecticide is a substance or agent producing or causing cancer. This is just one of the reason that I believe there are more cons then pros when dealing with a insecticide.. When I was a kid , I can remember my parents taking me and my brother an apple orchard and picking apples. I couldn't wait to eat them until I got home, but we couldn't eat an apple because of what insecticides could be on the apple

Persistent organic pollutant exhibit a process known as the “grasshopper effect,” in which these chemicals go through cycles of volatilizations and condensations — i.e., evaporation and atmospheric cycling in warmer climates and condensation and deposition in colder climates, thus moving these chemicals to remote regions where they have never been produced or used.
Pesticides are frequently used in this community. Almost all farmers use pesticides every day to help keep malicious, hungry animals away from their crops, most of which have been linked to illnesses further down the road by consumers, or even pregnant mothers in some cases, involving those responsible for applying the chemicals. All in all, it is no secret that these chemicals are nothing to toy with. As a matter of fact, they themselves have the potential to severely affect the health or kill unsuspecting, or perhaps impair workers.

As time has progressed, there has always been an overarching need for high amounts of crop production throughout the world. With the rapid rate of population growth, the need for crops and other sources of nutrients is only increasing. In order to meet these high demands and increase yields, farmers and other agriculturalists have started implementing the use of pesticides. These chemical mixtures are being used in order to prevent, destroy, repel or mitigate any pests from destroying growing crops. However, using pesticides on crops can create massive amounts of pollution, negatively affect an individual’s health, and can spark biodiversity loss within an ecosystem. According to Michael C.R. Alavanja, “Over 1 billion pounds of pesticides are used within the United States (US) each year and approximately 5.6 billion pounds are used worldwide”. With all this in mind, it is clear that pesticides should not be made available to farmers and agriculturalists, and should

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
Pesticide is a chemical used to prevent, wipe out and control the pest problem in agriculture. The use of pesticides have become a common practice around the world, and used almost everywhere, such as agricultural fields, homes, park and school, and so on. Most pesticides are insecticides, herbicides and fungicides that have distinct purposes. Insecticides are used to control insects; herbicides are used to destroy plants; fungicides are used to prevent molds and mildews. Most commonly pesticides contain highly toxic chemical such as Acid copper chromate (ACC), Acephate and Chlorpyrifos, and so on. One of example of insecticides, Chlorpyrifos, sprays widely on a variety of food and golf courses in order to control pests in a cornfield. However, “Chlorpyrifos can cause cholinesterase inhibition in humans; that is, it can over stimulate the nervous system causing nausea, dizziness, confusion, and at very high exposures (e.g., accidents or major spills), respiratory paralysis and death.” (EPA GOV) In the market has thousands of products are similar as Chlorpyrifos.
