Factors Of Organic Pollution Through The Palmer Index Scoring Method

The samples of unfiltered Rio Salado River water used in these experiments were collected from a site on the south bank of the river near S. 7th Ave. in Phoenix Arizona (see figure 1). The samples of water were collected by filling a three-gallon carboy by submerging it in the river. The carboy was then transported at ambient air temperature to the lab the same day it

As the data showed, the Conodoguinet creek is NOT polluted! There were many macroinvertebrates living in the creek that could only live in non polluted

The first piece of evidence supporting this statement is a water quality index of 48. The 7 pollution sensitive organisms in the creek are worth three points each on the water quality index, plus the 10 moderately tolerant organisms each 2 points and the 7 tolerant organisms each 1 point add up to get the 48 water quality index. The water quality level is considered excellent if it is 23 or above. The water quality in the U-High creek is more than twice that. There were many different types of organisms found in the creek including 7 pollution intolerant micro invertebrates. The total number of organisms including the 88 pollution intolerant Caddis fly larvae point to a low pollution level in the creek. The 10 moderately tolerant micro invertebrates also point to low polluted creek. There were also a high number of midges and aquatic worms. The water in the creek was also very clear and did not have a smell. There were many small fish and plants growing in and around it concluding a low pollution level in the

When there are excessive loads of Nitrogen and Phosphorous in the water, Alage can “bloom” to harmful levels, changing water color, and eventually stripping dissolved oxygen from the water when they die, fall to the bottom, and decay. This dissolved oxygen is critical to the health of the Chesapeake Bay’s critters and

to the body of Daphnia. For example, an experiment may test the effects of toxic chemicals on Daphnia, meaning that Daphnia can act as water quality indicators (Ren et al. 2009). The lack of Daphnia in certain areas signifies the presence of a toxic chemical, if the habitat meets the living requirements of Daphnia (Villegas-Navarro, 2003). Therefore, Daphnia act as indicators of environmental health as well as chemical responders reacting to potentially harmful

The dependent variable in the investigation was the 9 day algal growth in each solution. The growth of algae is gauged by the change in the turbidity of the algal solutions from the initial and final day of data collection. Turbidity is a measure of the loss of water transparency due to the presence of particles in the water. One cause of turbidity is the presence of algae in water. In this experiment, the main cause of the increase in turbidity is the increase

The water at the southern end of the island had a temperature of 21°C. Healthy marine water should have a temperature between 15°C and 35°C therefore the water is neutral. The water turbidity was relatively clear with almost no matter and very little sediments. The pH level was 7 on the universal indicator.

P. oceanica meadows are met in transparent and pure waters of Mediterranean area. The prevalence of Posidonia meadows in clear water is a useful tool for biomonitoring the clearness of the desired area. Along with Mytilus galloprovincialis, the Mediterranean mussel, Posidonia is a natural reservoir of different metals acquired from the environment. These metals are released from industrial, agricultural and urban activities in the coastal area and are one of the most persisting pollutants in the environment (Bethoux et al. 1990). Due to its sessile property, Posidonia is an ideal organism for biomonitoring. In a study conducted to compare the bioaccumulation level between M. galloprovincialis and P. oceanica, for cadmium, cobalt, chromium, nickel and lead, P. oceanica

The water quality is very important to the surrounding areas as it supports many different aquatic and terrestrial ecosystems. The oceanography class wanted to compare certain water quality from the Saint Augustine Municipal Marina (29.8916° N, 81.3103° W) to an offsite location. The offsite location the group had was Rookery Bay, FL (26.0500° N, 81.7010° W) towards the Southwest section of Florida. The group collected the water quality data from the Saint Augustine Municipal Marina on February 9th and 23rd and March 9th and 23rd around noon on each of the sampling days. The Rookery Bay water quality data was collected from the National Estuarine Research Reserve System where they listed the same data we were collecting. Based off the data collected from both sites the class raised the question of which water quality was better based off the

The introducing to any type of pollution, man-made or artificial, can have an outstanding effect to a natural environment. When the word of pollution is thought of, it’s never a positive thought and can do harm to where humans and many different organism lives. There are many different freshwater pollution and each one of having it one effect. One of the organism that live is fresh water is Ankistodemus, a green alga that grows in fresh water pond and lakes. When Sodium chloride (salt) is added to the alga environment what type of effect will it have on its growth? The importance of this experiment to make aware of how pollution have a stern effect on the living things around the Earth. Being alert of this will expression how putting more care on the environment will extend the life span of the Earth. The goal of adding Sodium chloride, the pollutant, to water, that Ankistodemus live in, is for illustration how Sodium chloride will inhibit the growth of Ankistrodesmus algae.

141 months) (Figure 1). Surface temperature and salinity were recorded in-situ using a handheld Yellow

Algae organisms are present in several ecosystems all over the world, including marine, freshwater, and soil environments (WSU Biology Department Faculty, 2017). Their relevant ability to grow in abundance depending on their environmental conditions may prove to be useful knowledge in the event that large amounts of algae need to be grown, such as in its role as a potential biofuel (Liang et al, 2009). Some algae are able to photosynthesize in the absence of light if glucose is present, but are primarily autotrophic in function (WSU Biology Department Faculty, 2017). In a similar study, a different type of algae, Chlorella

In practice the parameters describing ecosystem functioning can be determined based on the species trait composition (including life history, physiological, morphological and ecological traits). In comparison with conventional taxonomic diversity (that provides information on ecosystem structure), traits can be directly linked to the functional roles of species in the ecosystem and their responses to human-induced or natural disturbance. However assessment aquatic invertebrates species trait composition in relation to pesticide pollution (which is the focus of the current study) is not clearly documented. Effects of pesticides on functional characteristics of invertebrate communities require further understanding. So far only study of Liess et al (2005) introduced an index based on species traits in order to evaluate responses of aquatic invertebrates to pesticide effects.

1982) using pH meter. Similarly, sediment ammonia, nitrite, nitrate was analysed. Total organic carbon (Walkley, A.; Black 1934) of dried sediment sample was determined.

Vietnam is experiencing a rapid and significant structural shift of its economy away from agriculture, forestry and fisheries towards industrialization. This economic growth has brought significant benefits to the people of Vietnam. Income and education have increased, while poverty has substantially declined. However, natural resources have been severely depleted and environmental quality has declined due to the rise in pollution levels. http://icem.com.au/documents/envassessment/wb_cea/WB_CEA.pdf Figure 1 demonstrates that Vietnam is one of the highest ranked countries in the world in terms of pollution index.
