Each and every year, Millions and billions of pollutants and plastics were found across the
ocean. Where does it come from? How do we clean up? Is it a serious threat to human
society? Will it cause serious contamination and spoil the marine wealth of our world?
Marine water adulterants are a serious public concern because of its various disadvantages
and harmful consequences on living organisms. It is an integration of chemicals and
wastes, which may be due to industries and natural outcomes. Karenia brevis is the
harmful bacteria which causes red tide. The marine water pollution is one of the biggest
threats to human society and also for the marine organisms. Plastics are the main perils to
the forthcoming generations. The marine water is filled upto 60-90% of micro and macro
plastics and other adulterants. Even a plastic bottle can last upto 450 years in the ocean
without decomposing. Ocean pollution is whole scale, aggravating and constituting danger
to human lives and prosperity. The metals that are found in the ocean are highly malignant
which includes mercury,cadmium,selenium,lead and other organic compounds. The
marine water pollutants are discharged into the ocean by the three main ways ;1. By land
(industrial run-Offs, untreated water, usage of pesticides and fertilizers) 2. By air (usage of
harmful gases and burning unwanted chemicals) 3. By transportation (spillage of toxics
due to ship wreck). It can be identified by the sensors and by the Arduino.MQ7 PH Sensor,
Inductive Proximity Sensor are some of the sensors to detect adulterants in marine
