In most cases, this acid comes primarily from oxidation of iron sulfide FeS2, also known as pyrite or "fool's gold"which is often found in conjunction with valuable metals. Acid mine drainage is a major problem with many hardrock mines, including almost all mines where the metal ore is bound up with sulfur metal sulfide mines.
It is thought LSD causes it's characteristic hallucinogenic effects via interaction with the serotonin receptors in the brain. Serotonin is a neurotransmitter that helps control your behavior and mood, governs your senses, and moderates you thoughts.
The physical effects of LSD are unpredictable from person-to-person, and no one knows if they will have a good or bad "trip.
Use by the intravenous IV route will produce a much quicker action, usually within 10 minutes. If taken in large enough doses, the drug produces delusions and visual hallucinations. Overdose can lead to severe psychosis. The physical effects can also include nausea, loss of appetite, increased blood sugar, difficulty sleeping, dry mouth, tremors and seizures.
The user may also experience impaired depth and time perception, with distorted perception of the size and shape of objects, movements, color, sound, touch and own body image.
Sensations may seem to "cross over," giving the feeling of hearing colors and seeing sounds. These changes can be frightening and can cause panic. Some LSD users also experience severe, terrifying thoughts and feelings, fear of losing control, fear of insanity and death.
An experience with LSD is referred to as a "trip" and acute, disturbing psychological effects as a "bad trip". These experiences are lengthy, with the effects of higher doses lasting for 6 to 12 hours, and it may take 24 hours to return to a normal state.
Health Hazards and Flashbacks with LSD Under the influence of LSD, the ability to make sensible judgments and see common dangers is impaired, making the user susceptible to personal injury, which can be fatal. After an LSD trip, the user may suffer acute anxiety or depression, and may also experience flashbacks also called hallucinogen persisting perception disorderwhich are recurrences of the effects of LSD days or even months after taking the last dose.
A flashback occurs suddenly, often without warning, usually in people who use hallucinogens chronically or have an underlying personality problem.
Healthy people who use LSD only occasionally may also have flashbacks. Bad trips and flashbacks are only part of the risks of LSD use. LSD users may also manifest relatively long-lasting psychoses, such as schizophrenia or severe depression. Some users who take the drug repeatedly must take progressively higher doses to achieve the state of intoxication that they had previously achieved.
This is an extremely dangerous practice, given the unpredictability of the drug. In those 12 and older, lifetime estimates were 9. These last three estimates had held steady over the previous year.Acid rain, more properly termed acid deposition, is the input of acidifying compounds from the atmosphere to the earth's surface.
It is comprised primarily of sulfuric and nitric acids that are formed when emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) react in the atmosphere with water, oxygen, and other compounds.
Acid rain has negative effects on the environment in which we live. Since acid rain is a transboundary pollution problem, acidic emissions produced by one country can be deposited in another.
Sweden and Norway, for example, both receive more than 90% of their sulphur pollution from abroad. Acid rain has corrosive effects because it eats into metals and stone.
As a result, it has led to weathering of buildings, corrosion of metals, and peeling of paints on surfaces. Building structures made of marble and limestone are mostly affected by acid rain as the acid .
transport, and effects of acid rain, some issues are still debated, whichin turn cause polarization amongscientists, political parties, states, andcountries (5). If acid rain has got negative affects, it also has some positive ones.
1) It helps 2 slow down global warming. 2) It can lessen the affects of pollution. Wherever the rain falls, it can have a huge effect on soil, trees, buildings and water. Effects of acid rain have on our health? Acid rain affects human being in many different ways. One main way is our health.
Acid rain could also effect on the air which can makes the acid rain pollution.
