Epa 's Field Measurement Results

I will say that as much as the expression “Canary in the coal mine” implies an early warning of danger in mines so does it in water too. In this case the fish directly helps us know the extent to which our ecological sphere is damaged, and helps humans to take the necessary precautions to save the environment.

PH sensors are used in many scientific laboratories to measure the hydrogen-ion concentration of a liquid substance and to determine the basicity and acidity of a liquid. PH meters measure the electrical potential difference between a reference electrode probe and a pH electrode probe. Since these probes are very sensitive, they are required to be kept cleansed from contaminants. If exposed to contamination, one risks faulty or unreliable data, since their accuracy is dependent on a regular calibration and upkeep. To avoid this risk, and accurately measure hydrogen-ion concentration, the probes are kept in a buffer solution and calibrated before each use. [1]

The importance of comprehensive site investigations and getting the right report, and by an EPA accredited auditor can be seen in the court case Charben Haulage Pty Ltd v Environmental & Earth Sciences Pty Ltd (2004) FCA 403. In this case Caltex had obtained development consent from the local council to decommission a suburban service station and remediate it to residential standards. A condition of the consent was that an auditor accredited by the EPA would sign off the completed decontamination.

It “doesn’t really give you the whole picture” of what pollutants may be there, she explains. So she uses a combination of tests. These don’t look for particular chemicals. “This newer method lets the sample tell you what’s in it,” she

The final category, physical environment, measures areas like air pollution, sanitation, and factors indirectly related to pollution such as auto emissions measured by the number of lone drivers. Air pollution is measured as an “average daily density of fine particulate matter in micrograms per cubic meter (PM2.5) in a county” Drinking water violations are used to indicate water quality. A “yes” under the “drinking water violations” indicates the presence of a drinking water violation in at least one community within the county. Violations are related to contaminate level, residual disinfectant level, and treatment techniques. Jackson County ranks 88 of 115 counties in physical environment. Several programs and initiatives are in place in an effort to address health factors of residents of Jackson County. To improve the accessibility of healthy food, the Jackson County Health Department works alongside the parks program on the Eat Smart in Parks program offered throughout the

FWP officials took tissue samples from the dead fish to the US Fish and Wildlife Service Fish Health Center in nearby Bozeman, Montana. The whitefish were found to have died from Proliferative Kidney Disease (PKD), which is caused by a microscopic parasite known to occur in Canada, the United States and Europe. PKD kills fish by causing extreme inflammation in their kidneys and spleen. In the past 20 years, smaller and isolated outbreaks of the disease have occurred in two locations in Montana in addition to Washington,

The Atlantic cod fishery collapse left terrible ecological consequences. As mentioned above, the fishing technology was a major destruction to the ecological system by using deployment and draggers. The huge nets that were dropped and dragged along the bottom of the ocean destroyed the underlying eco-system in the process. The effect of selective fishing on spawning grounds – that is, selectively over-exploiting one species in an ecosystem – had disastrous effect on the feeding relationships in that ecosystem. This contributes to the overall reduction of spawning stock biomass of the targeted species, but also an increase in the number of invertebrate and vertebrate predators such as crustacean and fish which will prey on cod eggs, larvae, and younger fish. It is a little wonder that a species like cod, would eventually run into difficulties struggling to survive when its habitat is being continuously destroyed and the balance of their food chain had been wiped out.

The researchers collected clownfish from Korea. They used immature males, mature males, males sixty days after the removal of the females, males ninety days after removal, males one hundred and twenty days after removal, and females. They were all separated by the presence of mature ova or sperm. The fish lived in a one hundred and twenty liter tank at ninety two degrees celsius. After given the injection, the tissue was collected at zero, two, four, six, eight, ten, and twelve hours later. Three fish were all decapitated before the tissue was collected.

One more is bycatch. Fishing companies only want one species or two which they need for sell. But their nets and trawls catch anything what is in their way. Every year over 300.000 whales and dolphins pass away in these nets. Species that are not wanted and captured get toss out over the side of the boat. It does not matter if they are dead or alive.

Safety Considerations: • staining may occur on hands and clothes. • Dispose of the materials in their respective waste containers is essential for environmental purposes • Wear proper attire for lab, such as eye protection and a lab coat.

Majestic animals that live in the ocean are rapidly dying and subsequently washing up on numerous shorelines that touch the Pacific Ocean’s waters. Disposal of a variety of toxins and damaging waste finding a path into our oceans are to blame for the deaths, which are largely preventable. Sharks, sea turtles, whales, dolphins and birds are just fraction of the marine life that are suffering because they are becoming sick or are dying of starvation. Their food sources are diminishing or disappearing as the cycle of destruction continues on down to the tiny, minute plankton that are the core of the food chain in the ocean. Contamination is causing the sudden increase of marine life deaths in the Pacific Ocean. The most recent reports of dead sea animals found washed up on shorelines don’t state scientific evidence of the cause of the mysterious deaths.

According to the United Nations, 17% of fish stocks worldwide are currently overexploited; 52% are fully exploited; and 7% are depleted. This means that only an estimated 20% of worldwide fish stocks are not already at or above their capacity(Seafarms, 2013). Catches of Pacific herring have decreased by 71% since the 1960s, with Atlantic herring catches falling by 63%. Atlantic Cod catches have fallen by 69% in the same time(Seafarms, 2013). These are just a few of many facts and statistics on the topic of overfishing. The effects of these statistics and facts impact people’s and animal's lives around the
