14 samples of TSP and PMwere collected within the area of Amphoe Muang Pathumthani from 7 stations at Tambon Bang Prok Bang Duea Bang Khu Wat Bang Kradee Lak Hok Bang Changand and Kra Sang during February to March 2013 in order to evaluate the concentration of dust and lead concentration level by using ICP-OES. The result of this study shows the TSP ranging 0.03 - 0.32 mg/mmg/mμg/maverage of 0.04 ± 0.06 μg/mμg/m0.05 ± 0.07 μg/m10 3 and the average of 0.12 ± 0.10 3 . The concentration of PM10 is in the range of 0.06 – 0.21 mg/m3 average of 0.13 ± 0.06 mg/m3. Of the determination of lead in TSP concentration of lead found in the range of 0.01 – 0.18 3 3 while lead in PM10 found in the range of 0.01 – 0.21 3 average of 3. Assessment of the public health risk is found contamination of lead in the atmosphere of Amphoe Muang Pathumthani levels ranged from less dangerous except area Bang Prok is worth the risk is moderate danger.

This research aimed to study and analyse conditions and problems in designing and developing household and decorative products of One Tambon One Product (OTOP) small and medium enterprises (SMEs) in Pathumthani province. The informants were 4 OTOP entrepreneurs and 205 OTOP SMEs. The research was conducted by means of interviews observations and questionnaires. The data was statistically analysed using frequency percentages mean and standard deviation. The results showed that conditions and problems in designing and developing household and decorative OTOP products ranged from home-based production site a lack of knowledge in product design and development transportation creativity artistic relations product specifications marketing to product design and development laws. Four entrepreneurs from these groups of products: lotus-fiber flowers silk flowers and bamboo lamps were found to have the problem of dyeing materials whilst those from the group of Thai/Japanese clay flowers had the problem of clay. The researcher had analysed piloted and concluded the problems and then passed on product development techniques to the entrepreneurs. It was found that they could use the given knowledge to make beautiful products and they satisfied with the reducing cost of production.
