vehicle emissions of lead particles from most of the internal combustion engine emissions. Tetraethyl lead as antiknock agent added to gasoline in general lead content in petrol to 0.13% and 0.08%, tetraethyl lead generation lead oxide exhaust after combustion. Lead major role in the nervous system, hematopoietic system,UGG boots, digestive system and liver, kidney and other organs. Lead can inhibit the synthesis of hemoglobin metabolism, but also directly on the mature red blood cells. Enter the body through the respiratory system of lead particles, larger particles can absorb the mucus in the respiratory tract, and mixed in sputum and spit it out; smaller particles, then deposited in deep lung tissue, they are almost all been absorbed. Organs in the body of lead accumulated to a certain extent, will the human heart, lung damage, anemia, people, behavior Daisha, mental decline, inability to concentrate, severe high blood pressure may also lead to infertility as well. Based on the way into the body, can have up to 60% of the total intake of lead permanently remain in the body, more than adults as the blood mixed with 0.8mg of lead poisoning.
by the combustion of leaded gasoline, 85% of the lead into the atmosphere caused by lead pollution. Lead oxide is not only harmful, it will also adsorption catalytic converters in automobile exhaust catalyst surface, the catalysts have a one. 40 years since the 20th century, into the atmosphere through the burning car has reached millions of tons of lead has become a recognized global pollution.

noise is a risk factor for cardiovascular disease, the noise will speed up the heart of aging, increased incidence of myocardial infarction. Medical experts by human and animal experiments that chronic exposure to noise can increase the body of the adrenal glands, so that increased blood pressure, an average of 70 decibels of noise in long-term life of the people, can make the increased incidence of myocardial infarction 30%, in particular, higher incidence of noise at night will make. Survey found that residents living near the highway, myocardial infarction rate of increase of about 30%. Survey 1101 textile workers, the incidence of hypertension was 7.2%, of which up to 100 dB noise exposure by intensity, high blood pressure incidence rate of 15.2%.

ultraviolet radiation affect human health in many ways. The human body, such as sunburn can occur, eye disease, immune system changes, optical variable response and skin (including skin cancer) and so on. Skin cancer is a stubborn disease, ultraviolet light will increase the risk of this disease increases. UV photons have enough energy to break the double bond. Short-wave ultraviolet light through human skin deep, make the skin inflammation, the body's genetic material DNA (deoxyribonucleic acid) damage, so that normal growth of cells transformed into cancer cells continue to grow into a piece of skin cancer. UV rays may also be induced by measles, chicken pox, malaria disease, herpes, fungal diseases, tuberculosis, leprosy, lymphoma.
also cause the increase in ultraviolet radiation of marine plankton and shrimp, crab larvae, shellfish and a large number of deaths caused by certain biological extinction. The results of ultraviolet radiation also makes a rabbit suffering from myopia groups, thousands of blind sheep. the ozone layer absorbs most of
short wavelength radiation (eg ultraviolet), plays a protective role in humans and other organisms, but the chlorine and fluoride to promote decomposition of ozone to oxygen, destruction of the protective ozone layer, a human concern One of the important environmental issues

CFC is a man-made chemicals in 1930 by the United States, DuPont production. After World War II, especially into 60 years later, in large quantities, mainly as aerosols, refrigerants, foaming agents, solvents and other chemicals. In addition, halons (used in fire extinguishers), nitrogen oxides also cause ozone depletion.

in surface freshwater systems, phosphate is usually the limiting factor of plant growth, and in the water system, ammonia and nitrate are often limit plant growth and total production volume. Lead to eutrophication of the material, these water systems are often limited in content of nutrients, for example, in the normal phosphorus content of freshwater systems is usually limited, thus increasing the phosphate will lead to excessive plant growth, and in the sea water system is no shortage of phosphorus, and nitrogen content is limited, so adding these pollutants will eliminate this limiting factor, which appears excessive plant growth.

Acid rain is mainly man-made emissions to the atmosphere caused by a large number of acidic substances. China's acid rain mainly due to the burning of high sulfur coal and the formation, in addition, a variety of motor vehicle exhaust emissions is an important reason for the formation of acid rain.
acid rain in China, including three (of acid rain mainly: sulfuric acid type)
1. Southwest acid rain: Acid rain is second only to the central area heavily polluted areas of precipitation.
2. Central acid rain: now it has become the largest range of the acid rain pollution, acid rain, polluted the intensity maximum.
3. East coast of acid rain: pollution intensity is lower than its central and southwest acid rain

fireworks in chemical composition can be divided into the following four categories: (a) oxidant categories, including nitrate, chlorate, etc.; (b) of the flammable substances such as sulfur, charcoal, magnesium powder, red phosphorus, etc., (c) of the colored flame, such as a chin salt; sharp salt, sodium, copper etc., (d) other effects of drugs such as potassium picrate, PVC resin, hexachloroethane, the tomb of a variety of oil and nitrate compounds. Fireworks will produce sulfur dioxide, nitric oxide, nitrogen dioxide and other gases, fireworks, smoke generated in the combustion of nitrogen oxides are mainly nitrous oxide (N2O), nitric oxide (NO), nitrogen dioxide (NO2) , nitrogen oxide (N2O3), among which is the main component of total nitric oxide and nitrogen dioxide, the NOx (nitrogen oxides) said. NO2 than 4 times higher toxicity of NO, can cause lung damage and even cause lung edema. Chronic poisoning can cause the trachea, lung lesions.

some tiny red tide is water phytoplankton, protozoa, or bacteria, under certain environmental conditions to the proliferation and accumulation of sudden, causing a certain range time in the water discoloration. Therefore, the main reason for the red tide
eutrophication in the sea do not have this option, so we chose a direct consequence of water eutrophication of marine plankton sudden appreciation
< br> In addition: water eutrophication is the occurrence of red tide and the first condition the material basis of hydro-meteorological and water
changes in physical and chemical factors are important reasons for occurrence of red tide marine aquaculture in the self-pollution is one of the factors inducing red tide
because of red tide has become the scourge of the fishery, after the formation of toxic red tide, not only can cause death of fish and shellfish such as a large number of dead, and eating fish and shellfish that people also have a poisoning, or even be stricken dead. Therefore, red tide and marine fishing industry, aquaculture industry and even human public health are closely related, has become an important research topic worldwide.
