Chlorine in water
Sea water Pollution
Lourdes Abu Rumman
Sea Pollution by Oil
Acid rain falling in the sea together with chemical and waste water pollutants are causing more fish to die. 25% of sea weeds are endangered. Much of the plankton is destroyed. It is becoming dangerous to swim in the Medi-terranean.

Chlorine in water
Chlorine has a much lower boiling point than water, it vaporizes more quickly. Therefore, the steam in the shower can contain as much as twenty times the level of chlorine as compared to water that pours from the tap.
Life in the DeadSea
Life in the Dead Sea
Because of its configuration and proximity to a number of more developed nations, the Mediterranean is expected to be one of the first seas to suffer harm from man's impact.
Nuclear waste is one of the most dangerous wastes, generally a variety of solids, liquids and gases.
Almost any type of rubbish generated on land, including pollutants from household waste, industrial chemical waste, or even radioactive waste, had a chance of making its way to the ocean.
69 million liters of sewage partially treated or untreated entirely is pumped in the Mediterranean Sea directly. The Mediterranean is a shared resource for many of the countries which is being contaminated.
Climate changes cause differences in the amount of water falling in different places.
There are 14 climate models differ when it comes to the amount of rainfall in individual locations, they all point to the same average picture.
For every single degree Fahrenheit the global average temperature climbs, heavy rainfall will increase in wet areas by 3.9%, while dry areas will experience a 2.6% increase in time periods without any rainfall.
Toxicology studies found that even low-dose exposures to Dursban during pregnancy or just after birth may decrease the manufacture of DNA and reduce the number of cells in certain parts of the brain.
Pesticide contamination of groundwater is a subject of national importance because groundwater is used for drinking water by about 50 % of the Nation's population.
The dead sea or sea of salt has a 33,7% of salinity. It is earth's lowest elevation on land.
It has no outlet, so water escapes only by evaporation.
As fresh water evaporates, salty minerals dissolved in the water get left behind.
All forms of electricity generation have some level of environmental impact. Making electricity contributes 40% of world carbon dioxide emissions.
Greenhouse gases emissions from burning fossil fuels trap solar heat in the upper atmosphere that would normally be radiated into space. This process is causing the global temperature to rise.
Fish and shellfish may not be exposed immediately, but can come into contact with oil. Oil also has effects on eggs and larval survival...When exposed to oil, adult fish may experience reduced growth, enlarged livers, changes in heart and respiration rates, fin erosion, and reproduction
A total of 123 pesticides currently being used in the West Bank. Among them, fourteen pesticides are internationally suspended, cancelled or banned...
The total cultivated area of the West Bank is around 2 million dunums. Of this, only 100 thousand dunums are under irrigation, while 1.6 million dunums are rainfed and 300 thousand dunums are fallow lands .
It is estimated that 96.6% of irrigated land and 87.0% of rainfed land is treated with pesticide.
The effects are already having an impact on all life and could cause the extinction of as much as 30% of all species.While the sun provides a tremendous resource for generating clean and sustainable electricity without toxic pollution or global warming emissions.
Nuclear Waste is radioactive and that is the primary cause of the negative effects on human health and bodies.
Cancer is considered by most people the primary health effect from radiation exposure. Other stochastic effects also occur.
Chlorine itself is not the main problem; rather it has to do with what happens when the chlorine mixes with any type of organic matter in the water. When chlorine is added to water, it forms Trihalomethanes (THMs), one of which is chloroform, which increases the production of free radicals in the body and highly causes cancer, kidney and liver damage, immune system dysfunction, disorders of the nervous system, hardening of the arteries,and birth defects.
Chlorine eats away at the protective, natural lubricant — called sebum — that protects the hair shaft. This process can weaken hair, create split ends and banish glossy shine.
For so many years, people believed that there wasn't life in the Dead sea, but scientists found a new kind of bacteria in the bottom of the sea that couldn't survive without the deep springs on the floor, which provide fresh water.
There are 120 coastal cities that dump their sewage without treatment in the Mediterranean.
Maritime transport activities and accidents of ships pollute the sea every year with about two million tons of oil.
Industry causes water pollution including those received from wastes and secondary outputs, both from ships and factories, and thus lead to the elimination of life in water, or in some cases, to fish poisoning, and thus human poisoning.
Some of the main symptoms of human poisoning includes : headache, dizziness, feeling tired, kidney damage, severe disorders in the digestive tract, death may occur.
Untreated sewage may contain water; nutrients (nitrogen and phosphorus); solids (including organic matter); pathogens (including bacteria, viruses and protozoa); helminthes (intestinal worms and worm-like parasites).
Winters are shorter, fewer cold records are set, more precipitation is falling as rain and less as snow and snowpacks are shrinking and melting earlier. Whether precipitation falls as rain or snow, these extremes can heighten the risk of flood, and cause economic and social disruptions for communities unprepared to cope.
