With the development of economy and the progress of agricultural science and technology, the demand of straw as a domestic fuel has been greatly reduced, resulting in the phenomenon of straw burning becoming more and more serious, which brings many problems, such as air pollution, fire, and the aircraft cannot take off normally. In addition, the residue after straw incineration contains a large number of toxic and harmful substances, but people are notcare for it. Some are buried on the spot, which destroying the soil structure and causing a decline in the quality of the farmland; some othersare dumping into the sea, and form the straw incineration sediments after a long time of accumulation, which has serious impact on marine organisms. The accumulation of heavy metals is one of the main problems caused by the burning of straw. Taking Jiaozhou Bay as an example, the influence of straw incineration sediments on the accumulation of heavy metals in marine organisms around Jiaozhou Bay was investigated in this paper. Firstly, we used the atomic fluorescence photometer and the atomic absorption spectrophotometer to determine the content of various heavy metals in the surface straw incineration sediments and marine organisms of Jiaozhou Bay; secondly, the geochemical method is used to analyze the characteristics of heavy metal accumulation in marine organisms; and then we used the spearmari's correlation coefficient method to analyze the correlation of heavy metals content in sediments and marine organisms. The results showed that the accumulation ability of fish to heavy metals was the worst, while crustaceans and molluscs were stronger. Heavy metals in sediments could promote or inhibit the accumulation of heavy metals by marine organisms, which had the strongest inhibitory influence on crustaceans. The results can provide a basis for the selective breeding and planting of marine organisms.
