A pilot project's participants. To get rid of the hyacinth in Kings Bay, Water hyacinth in large plastic containers with a case capacity of 4,300 gallons per day. The water has been out of control for years, turning it into a slimy green mess. Bob Knight, the project's principal ecologist, is searching for a solution for all of the bays. This plant attracted gardeners in 1884, causing it to grow; during the Second World War, it grew even more when they built structures in the water. Knight spent a year obtaining permits to put the experiment to the test. When the first floating pens with hyacinths, native frogs, and water lettuce were implemented in March 2012, they believe hyacinths can play an important role in a conservation plan that involves reducing nutrient runoff and trying to restore spring flows.

Hyacinth is a type of hyacinth (aggressive non-native species, South America) Water hyacinth, sometimes known as the "weed from hell," is an available plant that can build impenetrable mats, attract mosquitoes, and deplete oxygen from the water, killing fish.Another fast-growing non-native species is Hydrilla.

Instead of removing the water hyacinth from the bay, conservationists brought it within, bringing roughly 4,300 gallons with them at the end of the day. In the 1960s, early control efforts included spraying areas of the bay with hundreds of gallons of sulfuric acid, which was later discovered to be harmful to other living things. Copper-based herbicide applications were also phased out in the 1970s after significant quantities of copper were discovered in sediments and dead manatee organs.

The water hyacinth enticed gardeners with its beauty and vigor after being introduced to Americans during the World's Cotton and Industry Centennial Exposition in New Orleans in 1884. It spread quickly from purposefully planted ponds and lakes, thanks in part to flooding. However, post-World War II development gave it a huge boost. Humans produced an excellent environment for the water hyacinth by damming rivers, draining wetlands, and filling water bodies with sewage and fertilizers.

It is a non-point since it has expanded globally making it grow in different five continents

It is biodegradable since it’s a floating aquatic plant, even if it is considered a invasive weed this is not any plastic or other material that is not biodegradable

It is chronic because everything points that this type of weeds will keep invading over many water sources, this has been going on for years affecting multiple aquatic animals and other aquatic plants, this can go for 28 years but as they keep growing and reproducing they will continue 

It's a primary pollutant since it was discharged directly from the source into the ocean, where it came into contact with the water. It's straight from the source.

On May 20, 2015, the founder and CEO of The Ocean Cleanup, declared to the world that his company will develop the world's first system for cleaning up plastic trash in the seas. This project was annoyed at Asia’s largest technology conference, Seoul Digital Forum, in South Korea and it was developed in 2016. This system will span 2000 meters, and it becomes the longest floating structure developed in the ocean, and this device collects plastic before it reaches Tsushima Island. Approximately one cubic meter of pollution per person is washed ip each year. This lead to Japanese government to look for innovations that may help this problem. The plans was to deploy a 100km-long system to clean up (about half of the ‘Great Pacific Garbage Patch, located between Hawaii and California), this in a time period of five years.
The pollutants:

The pollutants are the chemicals and the toxic particles that plastic drops in the oceans. It has been studied that plastic releases chemicals such as bisphenol A, is has been implicated in disrupting the hormonal system of animals, also other substances known as polystyrene-based (ps) oligomers.
The Impacts:

It is averaged that each year one cubic meter of plastic pollution is being washed in Tsushima Island. The world first ocean cleaning system is important to the ocean since it cleans waters and coasts and it is essential lo help clean our  oceans. This project has helped scientist to study the system’s efficiency and durability over time.
Identify of Point or Non-Point Source Pollution:

It’s a non-point source pollution since the plastic is thrown all around the world.

It is persistent since the plastic docent decompose. The plastic can be around indefinitely in the marine ecosystem. Some of the plastics float once they enter the ocean, other don’t. Some plastics that are thrown in the ocean beaks down into peaces called micro plastics.
Identify if Acute (oil sill) or Chronic (constant):

It can be considered chronic since cleaning the oceans will always be difficult since people are not going to stop using plastic. Plastic is everywhere and changing people minds about plastic will take many years. 

It is considered as primary plastic since is causing different combinations like cigarette butts and bottle caps. It can also be considered as a secondary plastic as a result of the degradation of the primary ones.

 

Summary: 

The European Parliament is working on banning single-use plastic. Single-use plastics are things like straws, cups, plates, cutlery, cotton buds, and more. What is to be implemented is banning plastics to come into force by all EU states. They have set goals such as manufacturing recycled bottles that are 25% recyclable in 2025 and by 2029 bottles that are 100% recyclable. There will also be strategies such as switching packaging that informs consumers of the environmental damage that the product they are bullying does. “Polluter pays” policies will also be applied. For example, fishermen who lose their nets at sea will need to pay an extra cost. 560 MEPs voted in favor of the agreement and these steps which are to be prepared for 2 years to later be implemented will change the course of Europe and the world. 

 

The pollutants:

The pollutants that come with plastic are mainly crude oil and natural gas. These plastics are spreading across the oceans and affecting wildlife. 

The sources: 

Comes from fishing industries, straws, cups, plates, cutlery, cotton buds, and more. All of these are human-sourced and Europe has “ 25m tonnes of plastic waste, but less than 30% is collected for recycling. More than 80% of marine litter is plastic”(Rankin). Europe wants to eliminate single-use plastics which cause littering, pollution, and also "fatbergs" which are wet wipes clogging sewers. 

The impacts:

Plastic is a huge problem worldwide. Single-use plastic which is used only once and is then disposed of is one of the most primal problems of the environment. It is present in the oceans in landfills and affects the flora and fauna all around the world. It also has a huge impact on humans and health. Plastics are turning into micro-plastics which apart from being ingested by animals, are now part of human systems even being found in human placentas. It also contributes to climate change because its incineration releases dangerous toxins into the environment. 

Types:

The U.S senate passed a ban on plastic microbeads which are really small pieces of plastic used for many different products and pollute the lakes and oceans. This ban is called the Microbead-Free Waters Act and it banned the manufacturing of microbeads by 2017, manufacturing of over-the-counter drugs and cosmetics that use microbeads by 2018 and the ban of the sale of these products by 2019. This is because they have found really high concentrations of microbeads in the great lakes, which not only affects the lakes, but also what lives inside them and allows for biomagnification to occur, which ends up affecting humans as well.

The pollutants are microplastics in the form of microbeads. They absorb more pollutants and since these are made of plastic, they don't decompose and if they do biodegrade, it takes a lot more than a 100 years for that to actually happen. 

microbeads are manufactured to be used mostly on abrasive exfoliants, facial cleansers, and toothpaste. All of these products rinse down the drain when being used and after that, they end up inside waterways and lakes.

When this pollutant goes into the environment, in this case being the great lakes, the fish inside the lakes consume the microbeads and introduce the pollutant to the food chain meaning that when biomagnification occurs, bigger animals and humans get affected.

Microbeads are a non-point source of pollution because it is not only one manufacturer that makes these or uses them and it is also used in very different ways as it can be used for cosmetics, pharmaceuticals, cleaning products, etc.

Microbeads are persistent pollutants as they not only do not biodegrade, but they also absorb pollutants around them.

It is a chronic pollutant because it will take a really long time for manufacturers to stop using them worldwide as it took 3 years to ban these from just one country. Also, since these plastics are really small, they are really difficult or even impossible to extract from lakes and oceans.

Microbeads are a secondary pollutant because they absorb pollutants and act more as the conductor of pollutants when being disposed of in lakes and oceans.

The pollutants: The pollutants of this lake are harmful chemicals like nitrates, potassium and sulphates which come from factories and other things nearby. Things like detergents, oil and grease also affect the lake and cause chemical reactions in it. 

The Sources: The pollutants come from construction and poor urban planning during the last decade as well as waste disposal and sewage in the lake or rivers nearby. 

 The Impacts: The impact of this foam is that it’s toxic for both the environment and the urban areas nearby. The clearest impact is that water is no longer available for use and the foam also has negative effects on people. It causes breathing difficulties and irritation on the skin. It has also killed wildlife and made the river uninhabitable for underwater species. 

 Identify if Point or Non-Point Source Pollution: The foam in the Bangalore lake is a non- point pollution because the waste has been piling up for decades and it comes from a known source like sewage or waste disposal, this also makes it a bigger problem for people currently living close to the lake.

 Identify if Persistent or Biodegradable: The toxic foam in the Bangalore lake is a persistent pollution because it comes from a chemical reaction and it does not go away or biodegrade. It’s been happening for decades and it hasn’t gone away. They also hurt the environment around them. 

 Identify if Acute or Chronic: This issue is chronic because it has been happening for a long time and it has serious effects on everyone around it. Aside from making it hard to move through the city it causes health issues and could even cause death in the future.

Identify if it is primary or secondary: This foam is a secondary pollutant since pesticides are man-made and it's a huge combination of chemicals. The problem is the fact that they can’t make it go away and it has become toxic for a lot of different organisms.

 2. The pollutants

toxic mud and waste material “tailings” 

3. The Sources

the iron ore operation at the mine just behind it.

4. The Impacts

Many Brumadinho residents died and disappeared. Brumadinho got hurt in a huge way, the houses were destroyed and many animals and plants died as a result of the disaster.

5. Identify if Point or Non-Point Source Pollution

point source pollution

6. Identify if Persistent or Biodegradable

It persists because Minas Gerais generates 53% of the country's entire iron ore output, and it is in danger.

7. Identify if Acute or Chronic

Chronic

8. Identify if it is primary or secondary

Primary

In eastern England, cocaine was found in shrimp samples in 15 locations around suffolk. Furthermore, ketamine, pesticides and pharmaceuticals were also found in the shrimps. Despite its quantity being small, it can potentially be harmful for wildlife and even to the people that consume it. This problem is increasing and as time passes there are more substances found in wildlife such as it was found on the shrimp.

 

Cocaine, ketamine, pesticides and pharmaceuticals.

 

 

Solid domestic waste, litter.

 

There is a big effect on wildlife, more species can digest these substances and would be very harmful for them. 

 

 

Nonpoint Source.

 

Biodegradable for the environment since it is digested by the shrimp. However it was found in their bodies which means it is still there, meaning that it can be considered persistent inside the shrimp.

 

 

Chronic-it keeps going and is something that doesn't stop

 

Primary since it is the source going in directly as a primary source.

The pollutants: The pollutants in this case study are primarily composed of fossil fuel burning and carbon dioxide emissions. 

The Sources:  emissions from cars and motorized vehicles, primarily public transportation vehicles containing diesel-based engines

The Impacts: It is said to cause severe lung and heart diseases, as it contains almost 20 times the healthy amount (as stated by the World Health Organization) of PM 2.5 particles per cubic meter

Identify if Point or Non-Point Source Pollution: The pollution in this case study can be identified as point source pollution, since it discharges directly from emission sources, such as motor exhausts and car pipes. 

Identify if Persistent or Biodegradable: This pollution is persistent, the particles are not classified as biodegradable. The particles are generally concentrated at certain times of the day, however, they persist throughout the day and never go away completely, which indicates that it is persistent.

Identify if Acute or Chronic: This type of pollution, and particularly in this location, is identified as chronic, since it keeps going and it will most likely never stop. 

Identify if it is primary or secondary: It is a primary source of pollution, as the source directly emits the pollution into the atmosphere.
