Toxicity, mutagenicity, and source identification of polycyclic aromatic hydrocarbons in ambient atmosphere and flue gas.

This study aimed to assess the characteristics of particulate matter (PM) and polycyclic aromatic hydrocarbons (PAHs) from various stationary and mobile emission sources in Taiwan, with a focus on source apportionment and associated health risks. The northern power plant, equipped with bag filters operating at 150 °C, had significantly lower FPM and CPM levels (0.44 and 0.

Dual bio-degradative pathways of di-2-ethylhexyl phthalate by a novel bacterium Burkholderia sp. SP4.

Burkholderia sp. SP4, isolated from agricultural soils, has a high capability of degrading di-2-ethylhexyl-phthalate (DEHP). It degrades up to 99% of DEHP (300 mg l) in minimal salt (MS) media within 48 h without adding additionally auxiliary carbon source.
