The Science News website explains how researchers are finding that everyday chemicals are ending up in our water. It discusses new chemicals that water treatment plants need to look for and treat in water.

This University of Technology Sydney video shows the research a team is conducting at the university surrounding toxic chemicals in fish that are commercially sold and eaten by people.

The EPA website explains the development and use of DDT and includes reasons it is no longer used. The website gives the current status of DDT and who can use it and for what reasons.

This NV at CEP Imperial video takes a historical look at DDT use. It shows how DDT was sprayed over everything all the time and when Rachel Carson wrote Silent Spring.

This video explains what PCBs are and where they are found. It gives examples of products that carry PCBs. The video briefly describes what PCBs are known to cause and gives a list of environmental professionals that individuals can contact.

The EarthEclipse website explains biomagnification and its causes. The website discusses how biomagnification happens in a step-by-step explanation.

This Amoeba Sisters video clearly explains biological magnification. It shows how the lower the animal is on the trophic level the less the toxin, and that animals on higher levels have to eat more of the contaminated organisms on the lower levels which increases toxicity in the higher animals.

Merriam-Webster Dictionary gives the definition of bioaccumulation.

This StrategicComm video describes the history of PCBs and defines bioaccumulation. It continues with discussing the warnings given for different kinds of fish because of the accumulation in certain organs and tissues. The video also gives guidance as to how to avoid PCBs through cooking.

This D News video takes a look at mercury exposure and bioaccumulation. It discusses how fish get methyl mercury and which people should avoid eating certain fish.

The EPA website defines nonpoint source pollution. It also includes possible nonpoint source pollution sources. The website also gives indications as to what individuals can do about nonpoint source pollution. There is also a fact sheet.

This Indiana Department of Environmental Management video shows nonpoint source pollution and explains how it gets into water.

The Yale School of Forestry & Environmental Studies website focuses on the radiation caused by Fukushima Daiichi nuclear power plant. It discusses the history of radioactive wastes being dumped into the ocean by different countries as well.

This longer video shows the history of radioactive waste dumping in the ocean. It talks about the movements of Greenpeace that lead to the stopping of the radioactive waste dumping. The video looks at the radioactivity on beaches and how this causes illness in humans. The video also very briefly talks about Fukushima.

The Earth Eclipse website defines thermal pollution and gives examples of the leading causes of thermal pollution.
