Pollution can lead to mutations in fish, frogs and other animals that live in water. This can affect our food supply as well as the quality of the food we eat. Another reason recognizing pollution in lakes is a good idea is that it is the first step in reducing pollution in lakes. In the beginning of this project I was looking for a way to measure water quality with…
In this lab my group and I learned about what type of test to conduct when determining a pollution source. I predicted that the Whitmore Strawberry Farm was producing the pollution that was causing algal blooms to form in the lake. The farm used a combination of organic and commercial inorganic fertilizers, which could have been the pollutant. The Whitmore Strawberry Farm was not the source of the pollution, the source was the Emerald Estates.…
My hypothesis, if we test the water from the Conodoguinet Creek for signs of pollution, then the results would be negative for the pollution because the water appears clear at most parts of the river, is somewhat correct. Based on our findings, the degrees of pollution of the Conodoguinet Creek are very low. The phosphate levels, phosphate meaning a salt or ester of phosphoric acid (mineral acid), are at most 1. Nitrate is a salt or ester of nitric acid. The levels of nitrate are also very low, up to 1.2.…
5. Substrate and aquarium live rock: You need to know which substrate is best for your fish tank. There are different kinds and if you get the incorrect kind, you might finish up slaughtering your fish. Live rock is also important; it acts both as a filter and a source of nourishment for the fish. Both substrate and live rock are an important part of you saltwater fish supplies for their classy value in the tank as well.…
Prior studies that have examined the independent effects of salinity and temperature on Daphnia have revealed that physiological rate processes including reproduction is negatively affected by increasing salinity, but the reproduction was positively affected by increasing temperature (Arner & Koivisto, 1993; Ghazy et al., 2009; Heugens et al., 2006; Schuytema, Nebeker, & Stutzman, 1997).…
When algal blooms are prevalent in bodies of water, specifically bays, they can cause the nitrogen levels in the water to increase. When the nitrogen levels in the water are increased, this can lead to a number of detrimental health effects when consumed. In order to determine whether or not the salinity of the water in Barnegat Bay had an effect on the rate of the nitrogen levels increasing during an algal bloom, ten sample of water were collected and tested by adding the microalgae Nannochloropsis and recording the nitrate and nitrite levels every week. The sample of water varied in salinity, and two samples did not contain the algae to act as a control. The samples were exposed to a temperature of 22°C and were tested over the course of…
Therefore, evaluation of negative impacts of pollutants on living organisms in the form of toxicity testing is routinely used to produce baseline data for environmental hazard and risk assessment of chemicals.94 Daphnia magna, an important link in the food chain of aquatic ecosystem, which is highly sensitive to toxic substances has been used to understand the toxic effect of waste effluent.94 To date, some explicit studies to understand effects of multiple stressors on aquatic ecosystem have been reported that are hints of how mange the freshwater in the wake of multiple stressors.95–98 The current project helps understand and compare toxicity of different stage of wastewater from influent to effluent in their intact and unaltered form.…
1. Planning for changes is difficult due to the natural fluctuation of the great lakes water levels but there are factors that are certain that the levels as well as the region are changing negatively due to climate change (Kahl & Stirratt, n.d.). The water levels of the Great Lakes have declined over the past decades (“Climate Change Indicators: Great Lakes Water Levels and Temperatures”, 2016). Climate change is a change in typical weather that lasts longer than usual (“Climate Change, Health, Environmental Justice”, n.d.). It typically comes along with the warming or cooling of the average temperature as well as extreme weather.…
The Chesapeake Bay’s water quality has been deteriorating over the recent years. Some reasons for the decrease in quality are agriculture, chemical contaminates, and sediment. Agriculture has caused problems for the Bay due to the use of fertilizer. When it rains, the excess nutrients run off into the waterways that lead to the Bay. These excess nutrients include nitrogen and phosphorus.…
In the hustle and bustle off everyday life, we as human tend to forget just how much man made pollutants we are letting out into the world. Not only do these fumes linger in the air we breathe but also run off into various water sources. Not only are we harming ourselves but also the living things that call the water their home. Some of the biggest pollutants that effect our water systems today are antifreeze from cars, cigarette ash and not to mention pesticides that run off from the fields. We know the effects of these harmful chemical substances can be deadly to humans but how does it alter the lives of the creatures living in the water?…
These pollutants have an adverse effect on fish populations in the bay further…
Investigating the light factors that affect the rate of photosynthesis in Elodea Fatima Hussien Sara House, Lesha Liles, Abigail Saucedo, Melrina Stemn Biology 1441_Sec 017, Monika Pradhan; October 6, 2015 All plants rely on photosynthesis, therefore, we examined the rate at which a submerged plant such as elodea photosynthesized, with different light factors. To do this, the elodea must be completely be submerged in deionized water, later place the two plants under artificial light and natural light. After an hour, elodea has to be removed from the beaker, add three drops of phenolphthalein and then add as many drops of sodium dioxide until the content has turned pink, into the beaker. The amount of sodium dioxide drops that are added to the content after the phenolphthalein will result in the amount of carbon dioxide.…
Figure 22. Relative mRNA expression in INS-1E cells after different chemicals treatment. Cells were treated with DHT, TCS and TCC for 48 h before RNA extraction for activity determination. Expression levels of the AR, pdx1, GK and Ins2 were determined by RT-QPCR and mRNA expression levels were normalized with TFIIB (A-D). DMSO treated samples were considered as control.…
Surface water pollution also can come into effect when sewages are filled with trash that later end up in the ocean. Oxygen Depleting pollution is when micro organism including mostly aerobic organisms such as bacteria, fungus and most other plants living in the ocean or other main bodies of water lose oxygen and become more susceptible to catching bad bacteria and loosing the little oxygen they need to survive. When oxygen becomes depleted also known as loss of oxygen the organism growth is more designated to grow and produce more harmful toxins that affect the plants and water quality around them. Some harmful toxins include sulfides and…
Introduction Eutrophication is a condition in an aquatic ecosystem where high nutrient concentrations stimulate blooms of algae (e.g., phytoplankton). Eutrophication is a natural process that occurs to all lakes over time as the weathering of rocks and soils from the surrounding area that leads to an accumulation of nutrients in the water. It can also be caused by run-offs of fertilisers. Three of the key components of modern fertilisers are nitrogen, phosphorous and potassium. After a rainy season these nutrients that were not absorbed, run off into waterways such as dams, lakes, rivers, streams, ponds and even sometimes swimming pools.…
