Evaluation of the anticancer activity and fatty acids composition of "Handal" ( L.) seed oil, a desert plant from south Jordan.

Background: The chemical composition of Handal ( L.) seed oil cultivated in Jordan deserts was characterized, and its bioactivity was evaluated.

Methods: The oil was extracted from the grinded seeds in 500 ml Soxhlet extractor for 24 hr using n-hexane, and the recovered fatty acids were methylated with methanolic-HCL.

BTEX indoor air characteristic values in rural areas of Jordan: Heaters and health risk assessment consequences in winter season.

Benzene, toluene, ethylbenzene, and xylene isomers (BTEX) are known to affect environmental air and health quality. In this study, the levels of BTEX compounds were determined in indoor air environments during the winter generated by several different heaters: diesel pot-bellied heater with chimney (DH); electric heater (EH); unfluted gas heater (GH); kerosene heater (KH); and wood pot-bellied heater with chimney (WH). The samples were collected using a diffusion passive adsorbent (activated charcoal) and then analyzed by gas chromatography-mass spectrometry (GC-MS).
