Kaoh­si­ung is us­ing drones to mon­i­tor air qual­ity: EPA

The China Post - - LOCAL -

Kaoh­si­ung in south­ern Tai­wan has been us­ing aerial photography to track down sources of air pol­lu­tion, with of­fi­cials say­ing the new tech­nol­ogy helps them work more ef­fec­tively.

The En­vi­ron­men­tal Pro­tec­tion Bureau of south­ern Tai­wan’s largest city, known for its highly de­vel­oped heavy in­dus­try, said it has car­ried two mis­sions re­cently us­ing un­manned aerial ve­hi­cles.

The op­er­a­tion has al­ready dis­cov­ered an un­der­ground con­struc­tion project and a ce­ment fac­tory in vi­o­la­tion of en­vi­ron­ment laws, the bureau said.

In the past, vi­o­la­tors could eas­ily cover up if they were us­ing ex­ces­sive amounts of gravel, while mon­i­tor­ing un­der­ground op­er­a­tions are es­pe­cially chal­leng­ing, ac­cord­ing to the bureau.

The bureau said it will carry out five more mis­sions in the near fu­ture to bet­ter track down il­le­gal be­hav­ior and col­lect in­for­ma­tion of data on par­ti­cles 2.5 mi­crons or smaller in di­am­e­ter ( PM2.5), some of which are caused by industrial ac­tiv­ity.

PM2.5 par­ti­cles are con­sid­ered par­tic­u­larly danger­ous be­cause they are usu­ally made up of sub­stances like heavy met­als that are more toxic, and can travel deep into the lungs.
