Ministerstvo \u017eivotn\u00edho prost\u0159ed\u00ed si nechalo u odborn\u00edk\u016f zpracovat studii, kter\u00e1 popisuje v\u0161echny aspekty souvisej\u00edc\u00ed s jeho samostatn\u00fdm ohla\u0161ov\u00e1n\u00edm.

Benzo(a)pyren se nach\u00e1z\u00ed v uheln\u00e9m dehtu, automobilov\u00fdch v\u00fdfukov\u00fdch plynech nebo i tab\u00e1kov\u00e9m kou\u0159i.

Vzniknout by kv\u016fli tomu musela dal\u0161\u00ed novela na\u0159\u00edzen\u00ed vl\u00e1dy o IRZ.
\n Studie podle Roub\u00ed\u010dkov\u00e9 popisuje v\u0161echny aspekty p\u0159\u00edpadn\u00e9ho ohla\u0161ov\u00e1n\u00ed, jako je popis l\u00e1tky, vliv na lidsk\u00e9 zdrav\u00ed a \u017eivotn\u00ed prost\u0159ed\u00ed a tak\u00e9 zp\u016fsoby m\u011b\u0159en\u00ed.

\n Aby byl benzo(a)pyren za\u0159azen na seznam sledovan\u00fdch l\u00e1tek v IRZ, po\u017eaduje u\u017e od vzniku registru v roce 2003 ekologick\u00e9 sdru\u017een\u00ed Arnika. Tehdy navrhovalo, aby bylo ohla\u0161ov\u00e1no 120 l\u00e1tek, ale kv\u016fli protest\u016fm z\u00e1stupc\u016f pr\u016fmyslu se seznam sn\u00ed\u017eil na 70 a pozd\u011bji 93 l\u00e1tek. Benzo(a)pyren se tam nedostal. <\/p>\n

„Studie do\u0161la k z\u00e1v\u011bru, \u017ee sledov\u00e1n\u00ed benzo(a)pyrenu by nemuselo vyvolat dodate\u010dn\u00e9 n\u00e1klady.

Ministerstvo zdravotnictv\u00ed podle n\u011bj v pracovn\u00ed skupin\u011b navrhovalo, aby se v registru objevovaly \u00fadaje o tom, jak moc jsou tyto l\u00e1tky toxick\u00e9. <\/p>\n
