identify four environmental problems that can effect public health ? give example?

Answer 1

1.
There are several main types of pollution and well-known effects of pollution which are commonly discussed. These include smog, acid rain, the greenhouse effect, and "holes" in the ozone layer. Each of these problems has serious implications for our health and well-being as well as for the whole environment.

2.
At high doses, lead (commonly found in old paint, household dust, soil, pipe solder and some ceramics) has long been known to cause severe health problems -- muscle and abdominal pain, mental symptoms, paralysis and even death. Until recently, however, we have not appreciated the devastating effect of low exposures early in life.

3.
Clusters of childhood leukemia appear to occur around hazardous waste facilities, including Superfund sites. Studies supported by NIEHS at the University of California-Berkeley are attempting to determine what environmental exposures, including tobacco smoke and poor diet, may lead to leukemia and how to identify those at risk.

4.
Research in Mexico in an area where DDT had been used for malaria control indicates that exposure in the womb during the first trimester is associated with impaired psychomotor development in children. The size of the effect of exposure to DDT is comparable to that of lead. No association was seen with exposure during the second or third trimesters. Environmental Health Perspectives

Answer 2

1. Leaking landfills can endanger the public through groundwater contamination.
2. Methane gas from landfills can endanger the public through chance of fire or explosion.
3. Air pollution in the form of smog or from accidental leakage of contaminants affects public health when people are exposed.
4. Floods can contaminate water supplies if they overburden the wastewater treatment facilities.

Answer 3

I present to you 1 issue with 4 consequences(but there are more)
1 issue: HCFC IN THE ATMOSPHERE
4 consequences:
introduction:
hydoclhorofluorocarbone it is the chemical mix content of refrigerants.
releasing this gas to the air it is harmful to public health because
1.-Transforms the Ozone cap.
how?
chloride it is an element that have special reaction with ozone molecules; when chloride reach the ozone lay one of the oxygen atoms of the three conforming the ozone molecule bonds the chloride atom, leaving the other 2 oxygen atoms together, then this clo-monoxide goes against another ozone molecule, bond the oxygen atom with it and then this molecule divides it self into 2 molecules with 2 oxygen atoms each. leaving the chloride atom free to stat over. one atom of chloride can transform 10,000 ozone molecules.
2.-solar beams reach earth cortex with out be filtered.
ozone it is the uv/ubv filter for our planet those rays from sun light are harmful. ozone filter it so the only rays those reach earth cortex are sun light and heat.
in America Latina there are special places as CHILE where there are some holes in the ozone lay with the dimensions almost of the state of Texas in U.S.A.
flora and fauna are severe damaging consequences as result of this prolonged exposition to the pure sun rays.
3.- sun rays provoque cancer of the skin
in the last 50 years the aumento of problems related with burning of the skin has been growing exaggeratedly, the reason, those holes in the ozone lets the sun rays to reach earth cortex and people, making burning to the skin those are irreversible damage. those burns develops cancer or melanoma malign, and carcinoma.
4.- acid rain are some of the consequences of ozone depletion.
acid rain it is the results of those chemical released to the air going from one place to another, mixed with dust, dirt, air and CO3 in the big wind loads, and when they condensate in some specific zones, precipices down toward the earth cortex, but those mixes are extremely dangerous, this acid it is as much corrosive as the hydro-chloridric acid or even the stomach acid.
you have to forgive me if any miss spelling.

Answer 4

My husband's MRI saved him from having a biopsy on his lung, which could have been significant surgical operation, costing way extra beneficial than the MRI. Your good judgment isn't logical. What are you going to do approximately human beings residing longer? Kill them? I consider the dire desire for tort reform....provide up the frivolous regulation fits and placed across down the huge fee of malpractice coverage and the unneeded sorting out that healthcare professional's order to stay away from the rattling courtroom circumstances! I thoroughly disagree with taxing medical reward or expenses! I pay sufficient. and that i do no longer belong to a union, nor does my husband.
