Effects of polluting Water with waste and Steps to Reduce the waste Video Lecture | Science Class 7

be the solution to water pollution is
the need of the are the major effects of
water pollution is the damage to the
food chain when harmful toxins are
present in water they are transferred to
higher level organisms through the food
chain heavy metals like lead mercury
iron cadmium aluminum and magnesium are
present in water sources
if these metals are present in the
sediment they reach the food chain
through plants and aquatic animals this
causes heavy metal poisoning in the
water polluted water is a hotbed for
diseases microbial water pollution can
spread infectious diseases such as
typhoid and cholera from drinking
contaminated water water pollutants
alter the overall chemistry of the water
causing changes in acidity conductivity
and temperature these in turn have an
effect on their marine life
heavy rain carries up dirt and silt and
deposit them into the water if the dirt
and silt settle in the water body then
these sediments prevent sunlight from
reaching aquatic plants if the sunlight
can't reach the plants they perish these
sediments also clog of fish gills and
suffocate organisms that live on the
bottom of the body of the water if oil
is spilled on the water due to accidents
the effects on the ecosystem and the
components are harmful many animals can
get destroyed in case the swallow oil
things we can do to reduce water
pollution are do not pour fat from
cooking or any other type of fat oil or
grease down the sink keep a fat jar
under the sink to collect the fat and
discard in the solid waste oven
do not dispose of household chemicals
our cleaning agents down the sink or
toilet avoid using the toilet as a
wastebasket most dishes wrappers dust
clots and other paper goods should be
properly discarded in a wastebasket do
not flush bills liquid or powder
medications or drugs down the toilet
install a watt efficient toilet
run the dishwasher or clothes washer
only when you have a full load this
conserves electricity and water use the
minimum amount of detergent and or
bleach when you are washing clothes or
dishes use only phosphate free soaps and
detergents minimize the use of
pesticides herbicides fertilizers do not
dispose of these chemicals motor oil or
other automotive fluids into the
sanitary sewer or storm sewer systems
both of them enter the river if you do
your part to prevent pollution in your
area then you will be helping to protect
water for both yourself and everything
else that relies upon this precious
resource so be one more to save the show
