Description
Technical field
The utility model relates to oceanographic survey and studying technological domain, specially a kind of micro- plastic sample acquisition of strand seashore
Device.
Background technique
Micro- plastics refer to micro- plastic grain of the partial size less than 5 mm.Currently, micro- plastics in ocean and coastal environment are as one
Kind emerging pollutant causes the highest attention of coastal state, while also causing many scholars at home and abroad to this emerging pollutant
Pay attention to.Micro- plastics have particle is small, enormous amount, can in water environment persistently enrichment, degradation speed slowly, be multiple pollutant
The characteristics of transfer vector, and human body can be entered by channels such as food, drinking water, threaten human health.It is international in recent years
The upper quantity in relation to micro- plastic pollution research report quicklys increase, and the research of China's related fields is still in starting and explores rank
Section.
Atmosphere, soil, water body, ocean and strand seashore etc. are concentrated on to the sampling of plastics micro- in environment and research at present
Region.Wherein seashore area in strand is the band across that extra large land interacts, while being also mankind's activity area the most active
One of.The plastic garbage that one side mankind's activity generates can by abandoning, the approach such as rainwash, sewage disposal facility come together in seashore
Band area, a large amount of plastic garbages present in another aspect ocean can be stranded in seashore by collecting under the effects of ocean current, tide
Band area.The plastic products for coming together in coastal region aging can be broken for a large amount of micro- plastic grains under physics, chemical factor,
Therefore micro- plastics investigation more options strand seashore is regional in the world.It is documented that micro- for strand seashore area at present
Plastic sample acquisition is mostly the sandy soil for collecting its surface layer 2-5cm, and sandy soil are then taken back FLOTATION SEPARATION in laboratory and go out micro- plastics
Particle, sampling tool over-borrowing help intertidal organism sample boxes to carry out.Intertidal organism sample boxes are to dwell for acquisition intertidal zone bottom
Biology design, application method are that intertidal organism sample boxes are placed in sandy soil surface, and frame takes certain sampling area, then uses
Spade/shovel, which takes, acquires its benthon sample, and sampling process is more rough, can not carry out phase to the sandy soil of surface layer certain depth
To accurate quantitative sampling, and intertidal organism sample boxes are mostly one meter of frame, and Sampling Area is larger, carry out strand bank using it
It is larger with weight that sandy soil sampling in beach will cause sample size, brings more workload to the processing of later experiments room and analysis.Now
Lack a kind of device for carrying out precise acquisition to micro- plastic sample suitable for strand seashore.
