RESUMO
Although the consumption of Pharmaceutical Plants has been eliminated during the development of chemical industries, it seems that the use of these plants is going to being increased. The attitude of people towards the consumption of Pharmaceutical Plants has been examined in this paper. The main aim of this study is the evaluation of Consumption Demand of Yasouj People towards Pharmaceutical Plants. This study has been done by survey method and via questionnaire about upper than 20 years old people of Yasouj city. Sample size, via Cochroan formula, was determined 380 cases. Sampling cases were specified by random cluster sampling. At first, 10 clusters selected out of all 20 clusters of Yasouj city, randomly. Then, from each selected cluster, 38 persons [include 19 men and 19 women] were selected [380 persons, totally]. Using SPSS software, data were analyzed. Findings of study showed that the awareness level and Pharmaceutical Plants consumption among women is more than men [pv<0.001]. There is significant difference between age groups due to the awareness level and Pharmaceutical Plants consumption [pv<0.001], so that the older persons have had more attitude towards and more consumption of Pharmaceutical Plants. Increasing the awareness level with the properties of pharmaceutical plants, training doctors in the field of herbal medicines, insurance support and the easy access of pharmaceutical plants compared to the chemical drug as the main factors will be increased the consumption of pharmaceutical Plants

Due to copper and zinc elements toxicity, a great attention to removal of those in order to reduce environmental pollution exist. This experiment was conducted to investigate the study of the effect of gravity single layer rapid sand filter on heavy metals [zinc and copper] removal efficiency in aquatic condition in different phosphate concentration. This study applied a gravity single layer rapid sand filter with silica sand media. Experiments conducted for all of the states of Copper and Zinc concentration in 25, 75, 125 and 175 ppm at different phosphate concentration present by varied discharge. Each state of Solutions pumped on top of the bed and discharge adjusted. Samples taken from effluent then acidified immediately with nitric acid. Metals concentration perused by atomic emission spectrometer with ICP source. Collected data analyzed by SPSS software. Founds from this study shown that maximum removal efficiency for copper and zinc was 98.89% and 78.60% respectively effect of discharge, metal concentration and phosphate concentration factors in removal efficiency of zinc and cooper, discharge and phosphate concentration bilateral effect on cooper removal efficiency, phosphate concentration and metal concentration bilateral on zinc removal efficiency, are significant in 1%. In addition, phosphate concentration and discharge bilateral effect, metal concentration and discharge bilateral effect are significant on zinc removal efficiency in 5%. Finally, bilateral effects of discharge and metal concentration also metal concentration and phosphate concentration have not significant effect on cooper removal efficiency. Gravity single layer of rapid sandy filter with silica sand media in order to cooper removal in low concentration can be used successfully. This method in high concentration of cooper and also different concentration of zinc had not successful result; but in this condition, may be use of a series of filter with more depth
