Effect of chlorinated monoaromatic hydrocarbons on biological membranes

Evaluation of personal exposure to monoaromatic hydrocarbons.

OBJECTIVES To evaluate the personal exposure of members of the general public to atmospheric benzene, toluene, and the xylenes, excluding exposure from active smoking. METHOD 50 volunteers were equipped with active air samplers for direct measurement of personal exposure to monoaromatic hydrocarbons (MAH) and an activity diary was completed during each sampling period. Exposures were also est...

Assessment of biological effects of chlorinated hydrocarbons in osprey chicks.

Osprey (Pandion haliaetus) eggs were collected during 1995 and 1996 at seven sites along the Fraser and Columbia River systems of British Columbia, Canada, and Washington and Oregon, USA. Fifty-four eggs were placed into a laboratory incubator. Thirty-eight of the hatched chicks were sacrificed within 24 h. Hatching success did not differ among sites and therefore between treatment and referenc...

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...

The Toxicity of the Chlorinated Hydrocarbons *

Because of their non-inflammability and their strong solvent properties the chlor compounds of the petroleum series have a wide and increasing use as degreasers of metal, cleansers of textiles, dry cleansers, solvents for rubber, tar, and gums, thinners for cellulose lacquers, and in treatment of garbage, tankage, and bones. Other uses are the production of high-grade lubricating oils from infe...
