โครงการการออกแบบและพัฒนาบรรจุภัณฑ์สำหรับผลิตภัณฑ์อโรม่า
This thesis is intended to design and develop packaging for aromatherapy products.The problems found in the area and observation are that the original packaging is made of plastic. Which plastics are materials that are not friendly to nature and are expensive Packaging is not unique. Can not separate the smell of each product smell. Because using all the same graphic packaging all smells And the graphics do not attract enough attention from consumers There is no floor to display products that are suitable and proportional.Is a major cause that requires the design and development of the structure and graphics on the packaging and the disply. The results of the research concluded that The packaging structure design has the highest level of satisfaction among the 3 experts.With an average of 4.58. The graphics on the packaging have the highest level of satisfaction among the 3 experts. With an average of 4.74. And the display has a high level of satisfaction among experts. With the average value of 4 and the satisfaction in the consumer packaging is the highest level With an average of 4.05. And the satisfaction in the consumer packaging is at the highest level With an average of 4.05 and consumers are satisfied with the most fragrant pillow packaging With the highest level of satisfaction with an average of 4.17. Followed by a large pack of soap With the highest level of satisfaction with an average of 4.12 and the third being small soap packaging With the highest level of satisfaction with an average of 4.12. The display has the highest level of consumer satisfaction at an average of 4.06
ความเป็นพิษร่วมกันระหว่างพอลิไซคลิกอะโรมาติกไฮโดรคาร์บอนกับไทรทรอนเอ็กซ์-100 หรือทวีน 80 ต่อการเจริญเติบโตระยะต้นกล้าของบานเย็นและกระเจี๊ยบเขียว
Use of synthetic surfactant is another choice to increase efficiency of polycyclic aromatic hydrocarbon (PAH) phytoremediation in soil. In this study the toxicity of soil contaminated with anthracene and fluoranthene at total concentration as 0 200 and 800 mg/kg in combination with 2 synthetic surfactants that were triton x-100 and tween 80 at concentration as 0 1 and 10 times of critical micelle concentration (CMC) on seedling growth of Hibiscus sabdariffa and Mirabilis jalapa. Both synthetic surfactants were watered separately on day 13 after inoculation and seedling growth were measured on day 20 after inoculation. The result shown that both H. sabdariffa and M. jalapa could grow in soil contaminated with anthracene and fluoranthene at all concentrations in combination with both synthetic surfactants. Tween 80 at 1 time of CMC were the least toxic to H. sabdariffa while toxicity of all surfactants on M. jalapa were not different. Decrease of plant growth depended on the increasing of PAH concentration in soil. With these reasons both plants were possible to use for PAH phytoremediation at total concentration 200 mg/kg in combination with synthetic surfactant
Phytotoxicity assessment of polycyclic aromatic hydrocarbons Co-Contamination in Soil during Economic Legume Seedling Growth
This research studied combined toxicities of 4 generally found Polycyclic Aromatic Hydrocarbons (PAHs) - anthracene fluorene fluoranthene and phenanthrene – during growth of 3 legume seedlings - cow pea mungbean and longbean - planted in varied combination of PAH contaminant in soil. Results showed that mungbean growth was more sensitive to PAH co-contaminated soil than cow pea and longbean. Co-contamination of all 4 PAHs was more toxic to legume than each pair of PAHs. Shoot length and fresh weight of legume seedling were more sensitive to co-contamination of all 4 PAHs than root length. Dry weight of legume seedling was the least sensitive to co-contamination of all PAHs.

Distribution and Phytotoxicity of Polycyclic Aromatic
Polycyclic aromatic hydrocarbons are a group of important organic pollutants and should be concerned. General sources of PAHs are contamination of petroleum hydrocarbons and incomplete combusion of organic compounds. The recalcitrance of these compounds depends on the arrangment of benzene rings and their molecular weight. Besides they are carcinogenic and mutagenic to animals PAHs show several toxicity to plant such as decreasing shoot and root growth and photosynthetic rate. PAHs are toxic to plant at molecular level such as increasing oxidation pressure and decreasing gene expression of cell wall-loosening protein expansion. Photooxidized PAHs showed higher toxicity to plant than parent compounds. Plant species and some environmental factors such as soil pH affect to PAHs phytotoxicity. Phytotoxiciy of Polycyclic aromatic hydrocarbons to crop plant growing in Polycyclic aromatic hydrocarboncontaminated soil is an important environmental concern
