Investigation and Draft Control Strategy for Dioxin and Heavy Metals from the Stationary Sources
Absrtact |
The scope of this project includes: (1) Establishing and updating of the dioxin and heavy metals emission inventory.(2) Monitoring dioxin, heavy metals and PBDEs for the stationary emission and the ambient environment.(3) Counseling the emission sources which had faild to meet the standards.(4) Investigating the speciation changes of mercury in cement plants and emission reduction strategies.(5)Assist with dioxin and heavy metals control, reduction, pollution incident.
The total dioxin emission quantity in Taiwan is estimated to be 52.65 g I-TEQ/year. As for the heavy metal emissions in 2013, the total lead emission is 13.88 metric tons/year, cadmium emission is 0.84 metric tons/year, mercury emission is 1.87 metric tons/year, and arsenic emission is 3.69 metric tons/year.
Dioxin emission monitoring for secondary zinc processing, secondary lead processing and RDF manufacturing were completed. Heavy metal emission monitoring for secondary aluminum processing, secondary cooper processing and crematoriums were completed also.
This year the ambient dioxin monitoring is targeted on the general monitoring stations and monitoring stations around major sources. Unusual emissions near the ShuiMei monitoring station was discovered and was improved. Comparing to last year‘s data, monitoring results are lower this year.
The monitoring results of ambient heavy metal concentrations are compliable to the EU
