How bad is 0.14 gram Dioxine release in the air by a pharmaceutical company in my area?

A pharmaceutical in my area releases 0.14 grams DIOXIN AND DIOXIN-LIKE COMPOUNDS in the air (according to a 2008 report).

Dioxine is very dangerous. How should I read this figure: how bad is it and according to what measure? Is there i.e. an EPA maximum for Dioxine release? I know the European Union regulates Dioxine release..

How can I make sense of this number?

Below is a link to the consumer fact sheet on dioxin put out by the Environmental Protection Agency (EPA). A number like .14 grams alone doesn't say enough to assess the danger. You also need to understand over what period of time it was released and the concentration in air and/or water measured in parts per billion or parts per million.
