Answer 1

There are various health issues due to the environmental pollution like the pollution caused by air,water,soil and food.Firstly dealing with the air pollution,air pollution is considered to be a mixture of chemicals,biological materials, and particulate matter which reacts with each other to form tiny hazardous particles. There are various health issues because of air pollution like breathing problems, chronic disease,premature mortality and increased hospitalisation .The air quality indicator is the concentration of particulate matter(PM).The guidelines given by world health organization recommends that the annual mean concentration should not exceed 10m per metre cube.It is considered to be associated with stroke, heart and respiratory diseases, and cancer , and with maternal and child health.The total number of deaths in Saudi Arabia in 2010 because of ambient pm pollution was 8550,due to household air pollution was 1471, due to ambient ozone pollution was 66, due to second hand smoke was 406, due to occupational air pollution was 42, and due to radon and lead was 7 and 719 respectively whose total accounts to be very high.Next talking about the problems caused by water pollution, Saudi Arabia is not only the worlds top crude oil exporter but also the biggest producer of toxic effluent that's the byproduct of slaking the desert kingdom thirst for water.Desalination in Saudi Arabia is the major cause for creating huge volumes of chemical- laced brine that is risking and contaminating the food chains because they are mostly untreated.Because of this people are affected by water-borne diseases like typhoid,cholera,paratyphoid fever, dysentery, jaundice, amoebiasis and malaria.water borne diseases accounts for squillions of deaths every year.Next talking about soil pollution,soil is getting contaminated because of the underground fuel leakage from gas stations in Saudi Arabia.Leakages and spills that arises from underground fuel storage tanks (UFSTs) can potentially contaminate soil and groundwater and can cause harmful effects to public health and the environment. There are many symptoms which appear in people who are in direct exposure to soil contaminants like chest pain,fatigue,eye irritation,rash,coughing,lung problems and nausea. There are also long term diseases like cancer including leukemia which is caused by the contact with soils contaminated with chemicals (e.g. gasoline, benzene),nervous system damage which is caused especially by the presence of lead (Pb) in soil, and affecting especially children, neuro-muscular damage and depression of the central nervous system,kidney and liver damage which is caused by chemicals such as mercury (Hg).Food hygiene and problems related to food borne outbreaks have become a matter of great concern for the food producing companies and government and also for food supply chains.Food pollution or contamination involving food poisoning has raised alarm in Saudi Arabia.During the annual hajj pilgrimage in 2006 a group of Saudi Arabia soldiers were diagnosed of having gastroenteritis which was caused because of following a rice lunch which was contaminated with Bacillius Cereus and Clostridium Perfringens.critical food control frauds, and infractions have been spotted at restaurants inspected in different parts of Saudi Arabia.
