1、Sources of pollutants, pollutants, etc. Pollutants. Pollutants. Pollutants2, according to the environmental factors affected by pollutants can be divided into 3, according to the form of pollutants can be divided into 4, according to the nature of pollutants can be divided into5, according to the ph

2、ysical changes of pollutants in the environment, chemical properties can be divided into two terms to explain 1, 2 pollutants, the safe concentration of 3, the maximum allowable concentration of 4, the effect of concentration of three, among the 1 properties, the 2 pollutants, the pollutants of the

3、3 classification, the plants on the adhesion of gaseous pollutants and absorption. 4, the pollutant migration in the plant body. 5 types, the combined effects of the compound pollution pollutants. Four, 1 essay questions, discusses the influence factors of plant absorption, migration of pollutants.

4、2, how to reduce the absorption of pollutants in soil in the actual production process? 3, absorption of soluble pollutants the water on the plant. Five, single choice 5, lethal concentration 6, covered 7, pinocytosis 8, additive effect9, synergy 10, antagonism 11, independent effect1, the toxicity

5、of the combined action of multiple chemicals is greater than the sum of the toxicity of each single substance. This is （A, additive action C, antagonism B, synergy: D, independent effect）:）Second chapters one, noun interpretation: noun interpretation:Bioenrichment1, bioenrichment （bio-enrichment） （a

6、lso called biological concentration （bio-concentration） 2）, enrichment coefficient or enrichment coefficient of 3, hyperaccumulator （hyperaccumulator） two, short answer questions 1, the nature of pollutants including those 2 pollutants which accumulate in organism after effect, why? What is the rela

7、tionship between the 3. Between the bioaccumulation and biological detoxification? 4, by extending the ecological system of the food chain bioaccumulation, what will happen, why?Three, fill in the blanks: fill in the blank: 1, the main factors influencing the biological enrichment are: 2, the influe

8、nce factors of accumulation in organisms, and, and.3, so far, Chinese scientists have only found arsenic hyperaccumulator plants; hyperaccumulator plants; manganese hyperaccumulator plantsZinc, segregation, hyperaccumulatorLead, segregation, hyperaccumulator plants4, the detoxification ability is mo

9、reThe enrichment ability is moreOn the contrary, the enrichment ability becomes more and more5, in the matrix solution, the pollutant can give （soluble） quantity 6, the soil moisture is too many, the pollutant is in the state primarily, the activity receives,The amount of absorption and accumulation

10、 of plants, the amount of enrichment, soil moisture,The quantity of pollutant is less, and the enrichment is 78, the wild plants are mainly wild plantsThe method9, investigation content of crops mainly cultivated crops in cereal and vegetables 10, there are four methods to study biological enrichmen

11、t on the subject: Essay: 1, why can the biological pollutant enrichment? 2, this hyperaccumulator has several major features. Methods, methods and3 different types of pollutants, and various pollutants in different organs of different organisms and the same organism, tissue accumulation have obvious

12、 difference, why? It should be how to reasonable layout structure of different types of crops in polluted areas, how to avoid excessive pollutants into the body? 4, what is the relationship between biological and environmental enrichment? 5. What is the best way of bioenrichment? Would you please de

13、sign a study of biological enrichment program. 6, the heavy metals as a special kind of pollutants, those characteristics are obviously different from other pollutants. （judge correct V wrong with * said） , X five,Judge: judge and explain the reasons for 1 points, 2 points, correct mistakes, with sa

14、id: （1） to determine the problem, with high chemical and biological pollutants can not be stable. （2 pollutant enrichment plants, is a fat soluble substances prone to enrichment plants （3. That has high water soluble pollutants prone to enrichment plants. （）4, matrix solution, exchangeable （soluble） pollutant quantity directly affect the plant absorption and enrichment. （six, multiple-choice: multiple-choice questions: 1, so far, Chinese scientists found only one of arsenic hyperaccumulation plants （A, B （s.alfredii, Wu Songcao） B wild plants, Joe, shrub leaf D, field sampling C
