Key Concepts

Sediments

Sediments refer to soil particles and other particulate matter that are washed into water bodies primarily through erosion and runoff. The accumulation of sediments can reduce water clarity, alter aquatic habitats by smothering plants and animals, and disrupt the natural flow and quality of water, impacting both ecosystem health and human use.

Chemical Pollutants

Chemical pollutants are substances introduced into water through industrial discharges, agricultural runoff, and improper waste disposal. These include heavy metals, pesticides, and other synthetic chemicals that can be toxic to wildlife and humans, cause long-term health issues, and accumulate in the environment, disrupting ecological balance.

Pathogens

Pathogens are disease-causing microorganisms, such as bacteria, viruses, protozoa, and parasitic worms, that can contaminate water supplies. Their presence in water can lead to waterborne illnesses, causing outbreaks of diseases especially in communities with inadequate water treatment, and they pose significant health risks through direct ingestion or contact.

Organic Wastes

Organic wastes consist of biodegradable materials such as plant and animal residues that enter water bodies. Their decomposition consumes dissolved oxygen in the water, leading to oxygen depletion which can cause eutrophication, fish kills, and overall disruption of aquatic ecosystems due to the imbalance in nutrient levels.

00:01 Hello there students today we are going to list the four categories of water pollutants and we're going to discuss what is slash are the sources of each and what are the harmful effects so let's start with the first one the first um pollutant um is bio degradable pollutants and what are they um they're basically they're basically biogradable materials that decays naturally being consumed or destroyed in a reasonable amount by organisms that live in soil and water and these could be sewage waste you know sewage or like you know wastewater from toilets or other household drainage um the seas organisms or like disease organisms such as typhoid or cholera where they carry they carried carried into the waterways of sewage of infected people.

02:55 And we got the sewage.

02:56 This includes food or human waste, soap, detergents.

03:05 And it also includes non -biodegradable chemicals that people often flush down toilite, paints, solvents, pesticides, and other chemicals down the drain.

03:19 Also another thing would be phosphates and nitrate fertilizers that flow into surface water, groundwater mainly from agricultural runoff and phosphates detergents, as well as phosphates and nitrates from philots also fall into this category.

03:49 And the harmful effect of this is that it can get into the into your groundwater or even your water where you can where you can ingest it and become really sick where it can lead to nausea diarrhea vomiting just really just you just you just definitely ill from that another another pollutant will bring up is non -biodegradable and pollutants and these are pollutants where these are materials that are not decomposed naturally by environment environmental chemicals or they are consumed by decay or with that there we just add them to find it and therefore they are non -briable and oops not all of these are poisonous but some are and the ones that are like really poisonous would be your persistent bio -oh -oh -oh -oh -lucky i'm writing way too half bio accumulative toxic chemicals are pvts and how the epa recognize tens of thousands of pvts and you have many factors where you have many organic industrial compounds are probably troublesome because of because they are toxic and high dosage are suspected to be carcinogens and low doses and can survive for decades in of chronic systems.

08:24 So that's one thing is really bad when they don't break down.

08:30 It could be a lot of them.

08:33 They are carcinogenics or cancerous and can survive for decades.

08:55 And aquatic systems.

09:03 And your examples could be your pesticides, your deosin, or son, are polychlorinated biphenyl compounds or your pcbs or toxic and agoric or organic compounds like something right there like let's this so we know what we're talking about here and right here where we could add up certain things like your mind waste road salt and dissolved ions like your cadmium's arsenic and lead and then another thing is where sediment enters surface water and neither fertilized nor poisons of archaic aquatic systems however the sediment muddies streams and berries aquatic habitats through degrading the quantity of the equals not degrading the quality of the quality of an ecosystem of an ecosystem and oops another pollutant will bring up is oops radio active material and with this, this could include waste from nuclear power plants, nuclear weapons, mining of radioactive ores, and medical and scientific applications, sorry, applications.

12:49 So with this, we kind of can know.

12:52 With this, more than likely, these are car.

12:57 And i got to look up because i forgot how you spelled carcinogenics.

13:02 I wrote it somewhere...
