In addition to their potential value for in situ bioremediation, the earthworm as a laboratory model may offer insight into mechanisms of xenobiotic toxicity. Using the filter paper contact toxicity test, the LD50s of a series of salicylates and phenolics were determined. The rank order in toxicity of these chemicals was compared with mammalian (rat, oral dosing) LD50s and found to be similar. To determine if protein secretion from chemical stress would be a more sensitive toxicity marker for the above xenobiotics, worms were exposed to either sodium salicylate or acetaminophen at a no effect level (NOAEL) and at the LD100 through filter paper contact. The ability of L. terrestris to metabolize drugs was investigated by using worm homogenate to treat various drugs in both encapsulated and free enzyme forms.

This thesis explores two literary texts written from a female working class perspective: Vad ska vi göra med varandra, a poetry collection by Jenny Wrangborg and Som hundarna i Lafayette Park, a novel by Anneli Jordahl. My aim for this thesis was to find out what kind of function war, seeking refuge, fighting for freedom, as well as experiences of these phenomena, have in the studied works. The categories class, gender, ethnicity and race have been interpreted through intersectional theories. The literary works have also been discussed by using concepts such as respectability, identification, alienation, solidarity, identity, wrath and cynicism. In conclusion, the study shows that the narrators identify themselves on basis of class to a greater extent than gender, and they use the experiences of other ethnicities and non-whites for comparisons with working class experiences as well as to create a common ground of solidarity. In addition, wrath appears as an important motive power in these works. Furthermore, the works got report book characteristics and lend voice to non-privileged groups of people, depict nuanced images of the alienation concept and show that dignity and solidarity can be used as rebellion against a cynical contemporary.
