Introduction Polycyclic Aromatic Hydrocarbons (PAHs) consist of two or more benzene-ringed compounds made of only carbon and hydrogen. Compounds which are made of two rings are known as di- aromatics whereas those made of three benzene rings are known as tri- aromatics and so forth. As the number of rings increase, molecular weights of these compounds also increase and the compounds tend towards

What are the effects of polycyclic aromatic hydrocarbons on the organ systems of aquatic invertebrates? A study in Biology Dusty Vincer, Advisor by Shruti Gajbhiye During the recent Deepwater Horizon oil spill, millions of gallons of oil were dispersed in the Gulf of Mexico in the same area known as the Gulf of Mexico Hypoxic Zone. The hypoxic zone along the Gulf Coast contains less than the normal amount of dissolved oxygen, at two parts per million. The little to no oxygen is theorized

The Battle Between Absorbency: Clay and Charcoal Abstract Polycyclic Aromatic Hydrocarbons (PAHs) are extremely dangerous to human and aquatic life when presented in water. The removal of the PHAs are done by using absorbent material. In this experiment we tested Bentonite clay and charcoal by finding the absorbency of both. The results we came to is the clay is the better absorbent. Introduction Polycyclic Aromatic Hydrocarbons (PAHs) are 16 different pollutants together. Eight of these

yards and reported water runoff and soil erosion from the waste management site. So, they were really concerned about their children health because they used to play in the area. As a result of that, we evaluated some polycyclic aromatic hydrocarbons. Polycyclic aromatic hydrocarbons (PAHs) are chemical compounds found in nature or released from burning of coal, oil, tobacco, and wood. Some of these compounds are toxic to lung, liver, and skin. By such Pre-PHA, We can know if the site is extremely

Four years ago from today, the Deepwater Horizon oil rig exploded and sunk, killing eleven people. Underwater cameras showed that the pipe was leaking oil and gas about 40 miles from the coast of Louisiana. This leak would eventually release about 4.9 million barrels of oil into the Gulf before it would be capped 87 days later. Immediately after the explosion, workers from Transocean, BP, and the government attempted to control the spread of oil to the coast by using oil booms and chemical dispersants

within the brain, and are formed via a variety of guidance cues and recognition signals, which direct outgrowing axons precisely to the target cell (3), with abnormal activity ultimately leading to cell loss and neuronal damage (1). Polycyclic aromatic hydrocarbons (PAH), a compound found within tobacco smoke (4), are toxic, carcinogenic and neurotoxic (5), and are also a common air pollutant generated during the incomplete combustion of organic material, such as coal, diesel and gasoline (5). While

The industrial Revolution was an event that changed the world forever. Tasks and lives became easier, cheaper, and more productive, but just like every decision isn’t there a consequence? The consequence to having machines and factories create our materials and goods on a larger scale, were the dangers created within our atmosphere and bodies. Fossil fuels such as coal, oil, and natural gas are used to create the needed and desired materials wanted today, but within the construction process pollution

Introduction . The intake of red and/or processed meat is a potential risk factor for colorectal cancer (Chenni et al, 2013, pg 227). One of the recommendations to reduce the risk of colorectal cancer is to reduce the intake of red meat (Takachi et al, 2011, pg 604). Higher instances of colon cancer have been found in men than in women, because men generally consume more red meat than women (Zhu et al, 2013, pg 2). Some studies prove that an increase of colon tumors in rats connected in

Keisha Williams Toxicology October 23, 2017 Toxicology Review Paper Due to the rapid economic development in three megacities in China, there has been a significant increase in the amount of polycyclic aromatic hydrocarbon (PAHs) in both the gaseous form and in the form of particulate matter( PM2.5 and PM10). On account of the rise of concentrations of PAHs in the air, the amount of both seasonal and annual pollution has increased well above the standard and national averages. Researchers collected

Governments Should be Responsible for Cleaning up Environmental Hazards from Previous Resource Use The responsibility of dealing with environmental hazards resulting from earlier resource use and environmental standards that are no longer acceptable today should be devoted in its entirety to different forms of government whether that be the federal, provincial or municipal level. This paper will discuss that only governments have enough money and resources available to adequately and efficiently
