Aluminum Contamination Due to Firework Industry

Collectively, the results for the biochemical tests and 16S rRNA gene sequencing suggest that the environmental isolate is of the Bacillus species and more specifically, is the bacteria Bacillus cereus. B. cereus are Gram-positive bacillus bacteria that are typically motile species, although some strains are not (BAM 2012, Bergey 1957).

In this experiment, we were given a sample of an unknown bacterium and asked to classify it based on its physical and metabolic properties. We hypothesized that the unknown organism was Alcaligenes faecalis, a motile Gram-negative bacillus that resides in water, soil, blood, urine, and feces (Herrera n.p.) It was first isolated in 1896 by Petruschky, who

These are the survivors thoughts on the Triangle Factory Fire. There was over 100 survivors but I choose two of the most important people who lived from the fire and I am sharing their thoughts.

The Triangle Shirtwaist Factory fire of 1911 was one of the most lethal workplace tragedies in American history. 141 young women died that day, because of their unsafe work conditions. If they had fire extinguishers and a sprinkler system, or even just a better fire escape, no one would’ve had to die. The girls did not have access to these things however, because they were not required by law.

An article titled, “The Calculation of Formation Curves of Metal Momplexes from pH Titration Curves in Mixed Solvents” showed a graph of typical titration curves, and the graphs curves and tendencies matched the graph developed in this experiment. Supporting the pH change inclinations described in the previous paragraph. “Buffers for pH and Metal Ion Control” by D. Perrin, also found that pH buffers resist changes in pH; “which were practically unaffected by the presence of traces of (acidic or basic) impurities… far from… dilute strong acids and

On April seventeenth, year 2013, a vast blast caused by several bins of fired ammonium nitrate fertilizer at the West Fertilizer Company and distribution facility in West, Texas occurred (Lateef, 2013). This disaster caused 35 people dead, which included 12 volunteer firefighters, no mention that over 100 people living nearby injured. (Dave 2014). The purpose of this report is to analyze the causes of this tragedy to find the shortage of storing flammable fertilizers in West fertilizer Company, also to provide a safer way or strategy to prevent a similar accident which may occur in the future time.

Every 4th of July, many people go out at night and spend hours watching firework shows. Most of us are content to simply enjoy the pretty colors and sparks, without questioning the chemistry behind the spectacle, but have you ever really thought about how fireworks produce such vibrant colors? The colors emitted when a firework explodes come from an aerial shell inside the firework that contains explosive chemicals and metallic salts. These colors appear to us because of luminescence. Luminescence occurs as a result of the valence electrons in the metal salt atoms moving and changing positions. The explosion of fireworks is not a miracle; it’s simply chemistry at work.

March 25, 1911 about 145 people were killed due to a tragic fire. The fire was called the Triangle Factory, it was one of the largest disaster in New York before 9/11. Before the fire there weren’t many rules that aided in the prevention of massive fires, and a lot of people died because of that. Since the fire new labor laws and fire safety laws.

During this investigation, I will be analyzing the aftermath of the Triangle Shirtwaist Factory Fire that occured in New York City on March 25, 1911. I will specifically be addressing the question, “To what extent did the Triangle Factory Fire of 1911 help give workers the reforms that they had already been demanding?”

If you have experienced a residential or commercial fire, hiring an NFPA 921 and ASTM compliant site evaluation is highly important because it means that you will identify the actual cause of the fire. The evaluation, evidence gather, laboratory testing and analysis will be more in depth and professionally done when you hire an expert. With professional fire debris analysis testing, you will be ensured that the real story of the fire gets told. In today's world, professional fire debris testing includes complete photographic capabilities. That means x-ray still photography, videography and Scanning Electron Microscope imaging.

Fireworks are made by electrons inside the atoms. The electrons get energy from the heat, which causes them to move from their ground-energy state to an excited state. Then these electrons go to a lower energy state and produce light with a specific energy and color. The color of the light produced by the electrons changes depending on the type of metal or mixture of metals. So, the colors are specific to the metals in the fireworks. That's why the colors of the flames were different depending on the element.

The most common point-of-use filtration media is activated carbon. Activated carbon is able to absorb organic and inorganic contaminates and are more commonly used to reduce any flavor or odor in the water2, 27, 28. In addition to the high surface area, activated carbon can chemically interact with heavy metals in the water. Most carbon materials like activated carbon are known to have high adsorption capabilities towards metal ions24. The pores of the carbon allow for trapping of large particles as well as increasing the available surface for contaminates to interact. Table 1 shows the overall size distribution of the activated carbon grains, average pore diameter and elemental composition of the activated carbon used for experimentation. The carbon has a rough exterior with many cavities and pathways for particles and ions in the water to filter (Figure 1).

Analysis shows the area surrounding the mine building contains the highest level of contamination on the mine site. Whilst the area remains uncovered by vegetation, particulates are prone to dispersion by wind action. There is low bioavailability of the contaminants in the soil, so precipitation is not a major factor in contaminant movement. However, a stream runs directly out of the underground mine entrance and into a river at the north of the site. Where the two water ways meet, metals can be seen precipitating out of solution proving contamination is

This is an interesting topic. I remembered that there was a piece of advertisement about spring water. It says “We are not the producer of water but the transporter of nature spring water”. I don’t think this word can make sense in today’s world. As many factories are built in the remote places, the industrial emission pollutes our waterways, ground water and drinking water.

Department of Transportation. The fireworks are all of high- quality, so no special storage was required.
