POLUTION

POLLUTION IS DEFINED AS ‘ ADDITION OR EXERCISE ADDITON OF CERTAIN MATERIAL TO THE PHYSICAL ENVIRONMENT( WATER AIR AND LANDS) MAKING IS LESS FIT OR UNFIT 4 LIFE.

OH BEUTIFUL 4 SMOGGY SKIES; 4INSECTICIDED GRAIN4 STRIP -MINED MOUNTAINS MAJESTY ABOVE THE ASFALT PLAIN .AMERICA -AMERICA ,MAN SHEDS HIS WASTE ON THEE ,AND HIDES THE PINES WITH BILLBOARD SIGN ,FROM SEA TO OILY SEA…………

GEORGE CARLIN

2009 HONG KONG INTERNATIONAL CONVENTION FOR THE SAFE AND THE PERSIST AFTER RELEASE ENVIRONMENTALLY SOUND RECYCLING OF SHIPS, THIS CONVENTION IS AIMED AT ENSURING THAT SHIPS,BEING RECYCLED AFTER REACHING THE END OF THEIR OPERATIONAL LIVES ,DO NOT POSE ANY UNNECESSERY RISK TO HUMAN HEALTHS ,SAFETY AND TO THE ENVIRONMENT.

WE HAVE TO WAIT AND SEE WHETHER BETTER DAY DAWN FOR ALANG AND ITS WORKER.

ACCORDING TO THE FORM OF WITCH THE PERSIST AFTER RELEASE INTO THE ENVIRONMENT

PRIMARY POLLUTANTS ; THESE PERSIST IN THE FORM IN WHICH THEY ARE ADDED TO THE ENVIRONMENT EG DDT PLASTIC .

SECONDARY POLLUTANTS THESE ARE FORMED BY INTERACTION AMON THE PRIMARY POLLUTANTS

PEROXYACETYL NITRATE PAN IS FORMED BY THE INTERACTION OF NITROGEN OXIDES AND HYDROCARBONS.

QUANTITATIVE POLLUTANTS: THESE OCCUR IN NATURE AND BECOME POLLUTANTS WHEN THEIR CONCENTRATION REACH BEYOND A THRESHOLD LEVEL EG CO2 NITROGEN OXIDE .

QUALITATIVE POLLUTANTS : THESE DO NOT OCCUR IN NATURE AND ARE MAN MADE E.G FUNGICIDES, HERBICIDES, DDT ETC.

MAJOR AIR POLLUTANTS AND THEIR SOURCES

CARBON MONOXIDE CO

IT IS A COLOURLESS ODOUERLESS GAS THAT IS PRODUCED BY THE INCOMPLETE BURNING OF CARBON -BASED FUELS INCLUDING PETROL DIESEL AND WOOD.

IT IS ALSO PRODUCED FROM THE COMBUSTION OF NATURAL AND SYNTHETIC PRODUCTS SUCH AS CIGARETTS

IT LOWERS THE AMOUNT OF OXYGEN THAT ENTERS OUR BLOOD.

IT CAN SLOW OUR REFLEXES AND MAKE US CONFUSED AND SLEEPY.

CO2

IT IS PRINCIPLE GREEN HOUSE GASS EMITTED AS ARESULT OF HUMAN ACTVITIES SUCH AS THE BURNING COAL 0IL NATURAL GASES.

CFC

THESE ARE GASES THAT ARE RELEASED MAINLY FROM AIR CONDITIONING SYSTEMS AND REFRIGERATION .

WHEN RELEASE IN TO THE AIR , CFCS, RISE IN TO THE STRATOSPHERE , WHERE ,THEY COME IN CONTACT WITH FEW OTHER GASES , WHICH LEAD TO A REDUCTION OF THE OZONE LAYER THAT PROTECT THE EARTH FROM THE HARMFUL ULTRAVIOLET RAYS OF THE SUN.

LEAD

IT IS PRESENT IN PETROL DIESEL LEAD BATTERIES PAINS, HAIR DYE PRODUCS ETC,.LEAD EFFECTS CHILDREN IN PARTICULAR IN PARTICULAR.

IT CAN CAUSE NERVOUS SYSTEM DAMAGE AND DIGESTIVE PROBLEMS AND IN SOME CASES CAUSE CANCER.

OZONE

IT OCCURS NATURALLY IN THE UPPER LAYERS OF THE ATMOSPHERE.

THIS IMPORTANT GAS SHIELDS THE EARTH FROM THE HARMFUL ULTRAVIOLET RAYS ON THE SUN

HOWEVER , AT THE GROUND LEVEL, IT IS A PLLUTANTS WITH HIGHLY TOXIC EFFECTS.

VEHICLES AND INDUSTRIES ARE THE MAJOR SOURCE OF GROUND LEVEL OZONE EMISSIONS.

OZONE MAKES OUR EYES ITCH BURN, AND WATER. IT LOWERS OUR RESISTANCE TO COLD AND PNEUMONIA

NOX

IT CAUSE ACID RAIN. IT IS PRODUCED FROM BURNING FUELS ICLDING PETROL, DIESEL AND COAL.

NITROGEN OXIDE CAN MAKE CHILDREN SUSCEPTIBLE TO RESPIRATORY DISEASE IN WINTERS.

SPM

IT CONSISTS OF SOLIDS IN THE AIR IN THE FROM OF SMOKE , DUST,AND VAPOUR THAT CAN REMAIN SUSPENDED FOR EXTENDED PERIODS AND IS ALSO THE MAIN SOURCE OF HAZE WHICH REDUCES VISIBILITY.

THE FINER OF THESE PARTICLES ,WHICH BREATHED IN CAN LODGEINOUR LUNG AND CAUSE LUNG DAMAGE AND RESPIRATORY PROBLEMS.

SO2

IT IS A GAS PRODUCED FROM BURNING COAL MAILY IN THERMAL POWER PLANTS.

SOME INDUSTRIAL PROCESSES, SUCH AS PRODUCTION OF PAPER ANSMELTING OF METALS ,PRODUCE SULFER DIOXIDE,.

IT MAJOR CONTRIBUTOR TO SMOG AND ACID RAIN.

SO2 CAN LEAD TO LUNG DISEASE.
