21,000 deaths/year

2: What is Radon Gas?
-A carcinogous,odorless, tasteless gas

3: Where is Radon found?
Everywhere in the U.S

4: How does Radon get into your home?
Cracks in solid floors, construction joints, cracks in walls, gaps in suspended floors, gaps around service pipes, cavities inside walls, the water supply

5: What level of Radon is considered unsafe? (indoors)
4 pCi/L

6: Is Radon in your home water supply considered to be a problem? Explain.
No, but it poses an inhalation risk and an ingestion risk. Most of the risk from radon in water comes from radon released into the air when water is used for showering and other household purposes. Radon in water is not a problem when the source is surface water, but when the source is groundwater then there is an issue.

7: How can you lower the Radon levels in your home?
Soil suction radon reduction system, contractor, private radon proficiency programs,

2: Under the “toxics” category- click on the link, “See how your county stacks up”.
List the 6 categories and relative percentage ranking for San Diego County.
1.Total environmental releases: 70-80%
2.Cancer risk score (air and water releases): 70-80%
3.Noncancer risk score (air and water releases): 60-70%
4.Air releases of recognized carcinogens: 80-90%
5.Air releases of recognized developmental toxicants: 60-70%
6.Air releases of recognized reproductive toxicants: 70-80%

Did the results surprise you at all, why or why not?
No due to the high amount of population.

3: Click on the “other chemical release and waste management attributes” link. List
the categories for which San Diego falls in the Dirtiest/Worst counties in the United
States (80-100%). How do you account for these levels being so high?
  • Water releases

<![CDATA[Scrapes: Radioactive Smoke]]>Fri, 11 Dec 2015 17:57:14 GMThttp://antonioscrapes.weebly.com/blog/scrapes-radioactive-smokeAuthor: Brianna RegoKeypoints:
  • Nothing is done to take the dangerous isotope from cigarettes
  • Polonium 210 is used in cigarettes
  • Poison builds to 300 chest xrays a year
  • Tobacco industry has known how to take it out of cigarettes for 50 years
  • 2009: obama signs
-Family Smoking Prevention
-and Tobacco Control Act into law
  • Vilma R. Hunt discovered a way to get it polonium out
  • Polonium 210 is a decay product of lead 210
  • Radon 222 decay into lead 210
  • Polonium is the cause of lung and many other cancers
  • Test confirmed 94% of hamsters developed lung cancer
  • Polonium responsible for 2% of smoke cancers
  • One way to fix the problem was to wash the leaves with hydrogen peroxide
  • 20-50% of polonium could easily be removed and washing could remove another 25%
  • World Health organization has made it clear that smoking is the most avoidable cause of death

Everyday, people die from smoking tobacco and cigarettes. Many of these deaths are due to the chemical in cigarettes called Polonium 210. If smokers inhale this product daily, it would be equivalent to 300 chest x-ray doses a year. This wouldn't be a problem if cigarette companies were to simply just remove it. The companies have even known how to take it out for over 50 years. Back then, the government was not as strong, but now it is. They should be able to enforce this carcinogenic chemical out of these widely used products but they are not doing their jobs. 2% of the daily smokers wouldn't have to die from cancer if they were to fix this problem now.

My thoughts:
I think that the government is becoming really lazy. It shouldn't be to hard to enforce some regulations on this chemical especially as it is widely spread and used in all of the U.S. If not taking this deadly chemical out, they should at least warn the consumer about it. Its like the tobacco companies want to kill their consumer. 2% of people may not seem much but placed over a huge population such as the U.S, would make it worth something. This should have been banned a long time ago.

So what?Polonium 210 is responsible for 2% of cancers from smoking
Says who?Says Vilma R. Hunt and Brianna Rego

What If?What if polonium 210 was taken out already, how much deadlier would cigarettes be?

<![CDATA[ScrAPES: Everyday Exposure]]>Fri, 11 Dec 2015 17:55:59 GMThttp://antonioscrapes.weebly.com/blog/scrapes-everyday-exposure
As the result of research that was done over 15 U.S States, it is now official that indoor concentrations of toxins are greater than outdoor concentrations. This is due to the fact that our everyday household items such as shampoo, house cleaners, and lipstick contain chemicals which are also toxic to the human body. Many people do not even recognize or are aware in the products that they buy just like of how unaware the government and law are. Many of the laws that contain regulations about toxins are based on outdoor sources. Though it is important to regulate the air in the natural environment, the government will need to come up ways to regulate the everyday household. Toxins in the home are just as deadly as the toxins outdoor.
These kind of articles really make me think twice about buying stuff at our local stores. Thinking about the kind of stuff that the industries put on our everyday household items and many other things sometimes just doesn't want to spend any money at all. Reading these articles however, have made me learn about these dangers and so I am able to spread it so many other people may learn as well.

I think that we should put more education in this topic more around the U.S. More education would make more people interested which would lead to making the government know about our issues eventually leading further into new regulations for the industries. We need to spread our thinking more than just the obvious as I also didn't know that toxins are more concentrated indoor than outdoor.

<![CDATA[ScrAPES Article: Tuberculosis]]>Mon, 07 Dec 2015 05:50:09 GMThttp://antonioscrapes.weebly.com/blog/scrapes-article-tuberculosis


​Tuberculosis is a leading cause of death in infectious diseases. Tuberculosis intervention "has saved over 43 million lives since 2000". Even though most cases of TB a be treated, death rates from TB are still high. More funds go into finding cures for AIDS/HIV than TB. The spending on researching TB is only $800,000 while the funding for AIDS/HIV research is about 8 billion dollars, about 10 times more than researching for TB. This difference is because HIV/AIDS mostly affects only poorer countries like Africa , while TB affects places like China and India, where they can fund themselves. The funding for both diseases should be equal, because TB is a curable disease and affects many in the poorer countries, which can "curb global deaths".
<![CDATA[scrAPES Article: Population, Poverty, and the Local environment​]]>Mon, 07 Dec 2015 05:49:56 GMThttp://antonioscrapes.weebly.com/blog/scrapes-article-population-poverty-and-the-local-environment

  • At a total fertility rate of seven or more, the chance that a woman entering her reproductive years will not live through them is about one in six.
  • Data on the status of women from 79 so-called Third World countries display an unmistakable pattern: high fertility, high rates of illiteracy, low share of paid employment and a high percentage working at home for no pay—they all hang together.
  • Many factors militate against poor households’ taking advantage of subsidized education.
  • The importance of gender inequality to overpopulation in poor nations is fortunately gaining international recognition.
The Author talks about how people blame population growth as a cause of poverty and environmental degradation. In developing countries, decisions on whether to have a child and on how to share education, food, work, health care and local resources are in large measure made within small entities such as households. The number of live babies a woman could have is she survived her childbearing years is called the total fertility rate, which is between 6 and 8 in Sub-Saharan Africa. When both parents participate in the decision to have a child, there are several pathways through which the choice becomes harmful to the community. Families with greater access to resources are in a position to limit their size and propel themselves into still higher income levels. One motive relates to children as ends in themselves. It ranges from the desire to have children because they are playful and enjoyable, to the desire to obey the dictates of tradition and religion. Rural assets such as village ponds and water holes have been owned communally. If access to shared resources continues, parents produce too many children, leading to crowding and susceptibility to disease and more pressure on the environmental resources. Importance of gender inequality to overpopulation in poor nations is fortunately gaining international recognition. Families with greater access to resources are in a position to limit their size and propel themselves into still higher income levels.
<![CDATA[ScrAPES: Toxins in your hair.]]>Mon, 07 Dec 2015 05:35:13 GMThttp://antonioscrapes.weebly.com/blog/scrapes-toxins-in-your-hair
A Brazilian blowout is a way of straightening your hair turning curly hair into fizz-free hair. However, this hair-do comes with a price. When attempting this, a chemical called toxic carcinogen formaldehyde is used as reported from the OSHA. A hairstylist from Portland, Oregon has attempted the brazilian blow out and resulted in shortage of breath, eye irritation and nosebleeds. Later effects of this chemical could result in cancer and leukemia. As more people began to report of these symptoms, the company responsible of the Brazilian blowout decided to make a new product that is formaldehyde free.

This article was very interesting because of its relativity to toxicology. To think that companies would lie just to be able to sell their products made me really engaged in this topic. After reading this article I got more interested in reading the ingredients of the products in my household to help keep my family and myself safe.

I think that the FDA should reintroduce the "Safe Cosmetics Act" and make sure that companies aren't secretly adding ingredients to the products. This will ensure safe products when they reach a house hold or in this case, hair salon. At home we can ensure our safety by reading ingredients. Being cautious about new products could help save the family from sickness.

Lead is poisonous and affects nearly every system in the body.

36: Why is it difficult to establish standards for acceptable levels of pollution? In giving
your answer, consider physical, climatological, biological, social, and ethical reasons.

It is difficult because the climate continues to change and people also live in different climates. Some climates such as living in the cold trap a lot of pollution but other places that are hot make it hard to find a right concentration of pollution for the people that live in each environment.
