Discuss and concern in the ecology of oil pollution.ppt

1、Discuss and concern in the ecology of oil pollution,Definition,Industrial production process a team-record oily materials and its derivatives into the environment caused by environmental degradation, affects the crowd and biological live normally phenomenon.,Oil of Marine biological effects,The oil

2、pollution directly affects the survival and development of Marine organisms, destroy the species diversity, radically affect the structure and function of ecological system foundation. Diversity is reflected the biological characters, community function is ecosystem development balanced a instructio

3、ns. Large populations of the diversity and with much more complex nutrition channel, more nutritional chains and side chain, and the density of population control function about through multi-channel role, community stability is bigger also. Therefore, the loss of ecosystem diversity, also will inev

4、itably result in the loss of ecological system complexity.,1. The influence of coral polyps,Coral and other sea animals the important and different is that they are not able to escape to get rid of oil pollution, but also cant hide in any a safe corner. The coral sea environment changes are particul

5、arly sensitive to the Marine oil pollution coral large area may well lead to death and destruction.,2. On the Marine biological larval influence,The tortoise, Marine biology for oil in deadly light aromatics material and its derivatives are highly sensitive, it is because their nerve centre and resp

6、iratory organs are very close to the skin, the skin is very thin, toxic substances easy to enter the body. And larval sports ability is bad, cannot seasonable escape from contaminated area.,3. On Marine benthic influence,After oil flooding, a considerable number of oil pollution derived substances,

7、even oil particles will gradually sink people under the sea. Benthos on often attached a thick covering of oil pollutant, make it hard to survive.,4. The influence of fish in,Polycyclic aromatic hydrocarbons hydrocarbons in Marine organisms, especially to benthic tissues and organs in together. When

8、 these poisoned by fish sea creatures, which also after eating will be poisoned. In addition, observed in petroleum contaminated area, and death of fish gills as full of many tiny oil droplets, or high strong milky liquids.,5. To JiPi animals influence,JiPi animals in seawater in any matter have sen

9、sitivity, especially for oil pollution. Pomerol, after oil tanker crashed observation results confirm, originally there are massive starfish and sea urchins maritime, suffer from the oil pollution after six years, not found starfish, sea urchins reanimate, indicating that the oil pollution of starfi

10、sh and sea urchins JiPi animals such as the potential threat is very big.,6. The influence of crabs,American Marine biologists studied in 1969 occurred in the eastern United States waters of a moderate oil flooding event consequence points out, until 1976, oil flooding sea crab of the total number o

11、f had not regained 1969 previous level. And the oil pollution to the harm of crabs survivors have various performance, such as movement stagnant, malformations, slow growth, etc. Until after the oil flooding in a 5 years, four crabs biological cells and tissues, still found remains oil derivatives q

12、ualitative trace. Until 1976, in the bottom of the gulf oil pollution in sediments, still preserved the remarkable pollution trace.,7. The influence of birds,With the ocean relationship, but also the birds oil pollution victims. Scientists research indicates that only beihai park and the north Atlan

13、tic for oil pollution died each year, 10 million birds formule above, and it actually only accounted for 10% of the total amount of the Dead Sea. Birds the cause of death is full of birds, oil pollutant feathers, undermining the gap between the feather capability of heat preservation and easy to mak

14、e its ShouLeng death. In addition, seabirds also usually put oil or its yan content eat into his stomach, make its internal functions have been fatal damage.,How to prevent and control the oil pollution,a. Formulate relevant regulations, stop Marine activity process illegally discharge oily wastewat

15、er, strictly control the coast oil refineries and other plant of oily wastewater discharge.,b. Monitoring surveillance area of oil pollution condition, improvement of the liner navigation communication devices such as performance, prevents the sea accidents.,c. Occurred after the oil pollution, can be applied to surround oil column of the oil slick surroun
