Description
Technical field
The invention belongs to technical field of soil remediation, be specifically related to a kind of polycyclic aromatic hydrocarbon pollution repair materials.
Background technology
Polycyclic aromatic hydrocarbon (PAHs) is the staying quality poison material of a quasi-representative, essentially from Fossil fuel and biomass not
Burn completely.PAHs has persistency, long-distance migration, lipotropy and " three cause " toxicity, ubiquitous in surrounding medium.
PAH also can be through waste water, waste residue and contaminant water and soil, and the depositing dust in air also can drop to water body and soil.Wherein, soil is
One main remittance of PAHs, in soil, the level of PAHs and composition characteristic can the pollution situation of PAHs, masters in reflecting regional
Originate.During Chinese soil Survey of contaminating status is evaluated, the evaluation reference value of soil multiring aromatic hydrocarbon is 100 μ g/kg.
Polycyclic aromatic hydrocarbon PAH is the hydro carbons in molecule containing two or more phenyl ring.Phenyl ring connected mode has two kinds, and non-condensed is even
Connect, there is no carbon atom in the ring shared between the most each phenyl ring, such as biphenyl, diphenyl-methane etc.；Condense connection, i.e. have between benzene two or
The carbon atom that two or more shares, such as naphthalene, anthracene, phenanthrene etc., this compounds is also known as condensed-nuclei aromatics, and many of have carcinogenecity,
During research environment pollution problem, alleged polycyclic aromatic hydrocarbon is often referred to condensed-nuclei aromatics.
PAH can enter human body through respiratory tract, skin and digestive tract.Enter PAH in human body by mixed-function oxidase,
The effect of aryl hydrocarbon hydroxylase the most contained therein, generate various polarity metabolite, major part through bile, fraction through urine ejection
External.In PAD metabolic process, having multiple intermediate product, some of which product is it has proved that have carcinogenecity, here it is through generation
Thank to the ultimate carcinogens that activation generates.
Cleaning ambient contains the PAH of trace, is fire and the volcano eruption deriving from forest and grassland, in nature
Some antibacterial can also synthesize PAH, and these just constitute the natural background of PAH in environment.
PAH, as environmental contaminants, is mainly derived from organic imperfect combustion.Life and production activity the mankind
In, the burning of various fuel (coal, oil, firewood etc.), all can produce a certain amount of PAH, side by side in surrounding.
PAH also can be through waste water, waste residue and contaminant water and soil, and the depositing dust in air also can drop to water body and soil.People
The food of class except can because of empty gas and water, the pollution of soil and by the pollution of PAH in addition to, processing, transport and preserve in also can make food
Product are contaminated.
PAH can enter human body through respiratory tract, skin and digestive tract.Enter PAH in human body by mixed-function oxidase,
The effect of aryl hydrocarbon hydroxylase the most contained therein, generate various polarity metabolite, major part through bile, fraction through urine ejection
External.In PAD metabolic process, having multiple intermediate product, some of which product is it has proved that have carcinogenecity, here it is through generation
Thank to the ultimate carcinogens that activation generates.
Coal smoke, white carbon black, coal tar, Colophonium, paraffin and mineral oil etc., all contain PAH, contact the workman of this kind of material, skin
Skin cancer is the most common.
Pulmonary carcinoma accounts for tumor mortality rate first or second in many countries.Think and connect with smoking, atmospheric pollution and occupation
Touch relevant.Containing multiple carcinogenecity PAH in the flue gas of tobacco shred burning.
Polycyclic aromatic hydrocarbon (PAHs) is the staying quality poison material of a quasi-representative, essentially from Fossil fuel and biomass not
Burn completely.PAHs has persistency, long-distance migration, lipotropy and " three cause " toxicity, ubiquitous in surrounding medium.
Wherein, soil is a main remittance of PAHs, and in soil, the level of PAHs and composition characteristic can PAHs in reflecting regional
Pollution situation, main source etc..
At present the pollution situation of PAHs in soil rarely had report.
" Dalian University of Technology " is at " contamination characteristics of Liaoning Area PAHs in soil, a source and carcinogenic risk " literary composition
In by the topsoil sampling analysis to Liaoning Area and Typical Urban Daliang City, to the PAHs contaminant water in this region
The aspects such as flat, composition characteristic, main source and carcinogenic risk are studied, and this result will assist in understands PAHs in depth and exist
Distribution and environment in a big way return, and provide with restoration of the ecosystem for research Northeastern rust belt environmental pollution formation mechenism
Important basic technology data.Level and the distribution characteristics of PAHs in difference in functionality district, Dalian Area soil are investigated.With the world
Other city is compared, and the PAHs in the soil of Dalian Area is in medium pollution degree.Different sampled point concentration are urban transportation
The trend that district's Urban House/area, suburb rural, park district (island) reduces successively, shows that urban transportation is in soil
The impact of PAHs is clearly.Four functional areas, the ratio that different number of rings PAHs account for ∑ PAHs is regularity change: along with far
From urban area, the ratio of Fourth Ring PAHs is gradually lowered, and the ratio of three ring PAHs is then gradually increasing, and this graded is main
It is owing to the difference of the aerial migration ability of different number of rings PAHs causes.The analysis of PAHs isomer ratio shows, in city
Area, PAHs is essentially from traffic emission, and in suburb and rural area, PAHs is essentially from coal and the burning of biomass.Profit
Concentration with benzo (a) pyrene (BaP), it is possible to instruction soil in PAHs based on BaP and 2,3,7,8 substituted two English (2,3,
7,8-TCDD) toxic equivalent, has good linear relationship between three, be to evaluate the one of PAHs toxicity in surrounding medium
The effectively method of simplicity.By investigating level and the distribution of PAHs in the soil of Liaoning Area, in finding region, have more than half
Place belong to moderate or serious PAHs pollutes, even the remote districts away from mankind's activity are polluted by PAHs the most.
Compared with other areas, the ratio of Liaoning Area soil China and Philippines is higher, accounts for 16.3% (averagely) of ∑ PAHs.In soil, PAHs is dense
Degree and soil organic matter content do not have dependency relation, and the soil organism is not the principal element determining PAHs concentration.By right
In soil, the dependency of 15 kinds of PAHs and the analysis of isomer ratio show, the PAHs in this area's soil is from multiple sources
Compound, and show the feature as main source with coal and biomass combustion.Application nonnegativity restrictions factor-analysis approach, it is judged that
In the soil of Dalian Area, the main source of PAHs is traffic emission and civil, and wherein, Traffic Sources is Dalian Area soil
The main source of middle PAHs, accounts for the 74% of total amount, next to that civil, accounts for 26%.Meanwhile, analyze each sampled point this two
Plant the respective contribution amount in source.The main source of PAHs totally 4 in the soil of Liaoning Area, respectively: coal burning, biomass fuel
Burn, coke production uses and " other " source." other " source is probably the result of multiple source type immixture, and these 4 kinds main
The contribution rate in source is 50.5%, 19.4%, 27.0% and 3.1% respectively.As a example by Dalian Area, applied probability carcinogenic risk
The PAHs carcinogenic risk to human body in the methods analyst soil evaluated.To three kinds of direct route of exposure, contact skin and eating
The accumulated probability of soil be the lifelong carcinogenic risk (ILCR) of 90% more than 10～(-6), show human body can cause potential cause
Cancer risk, and breathe the ILCRs that accumulated probability is 90% of soil particle thing much smaller than 10～(-6), show because breathing soil
Grain thing and the carcinogenic risk that causes can be ignored.And due to physiological feature and the difference of living habit, the people of different age group
The ILCRs that the different ways of contact are caused by group (child, youth and adult) is different.By to probabilistic sensitivity
Analyzing, what discovery affected maximum to carcinogenic risk evaluation result is the equivalent concentration based on BaP of PAHs in soil and is exposed to
The ratio of the skin area of soil.This result shows, to reduce the uncertainty during carcinogenic risk is evaluated, first should reduce
The centinormal 1 uncertainty of PAHs.
Rarely seen about the document removing PAHs in soil pollutant at present.
Accordingly, it would be desirable to for the feature of polycyclic aromatic hydrocarbon, grope a kind of remove polycyclic aromatic hydrocarbon effective and relatively mild not
Produce new contaminated soil renovation agent.
