Hydrocarbons and chlorocarbons
may also be partially oxidized in this zone, resulting in emissions including oxy-PAHs and oxychloro-PAHs (Rubey WA et al., unpublished data).

: A significant global source of background rain acidity.
An upgrade of the ImmEdge Pen, the hydrophobic barrier pen for immunohistochemistry and in situ hybridization, is void of "ozone-depleting" substances (ie, fluorocarbons and chlorocarbons
), notes the company.
However, under pressure to regulate the use of chlorocarbons
, 1-BP has been used as a surrogate, which is encouraged by the lack of measures to define the exposure limits.
