This year, the UESTC iGEM team has conducted many human practices to disseminate iGEM and our project. One of them is a questionnaire survey which gathers the information of public awareness of synthetic biology, formaldehyde and last but not least, their perspective on the trans-genetic plant which can absorb formaldehyde. Last, we analyzed our research data, and come to a conclusion of our activity, and made many charts or diagrams to make people easier to understand.

Statistic

Analysis

From the charts, we could get the information that, for these questions, the number of male slightly exceeded the number of female’. And this excess is trivial enough to guarantee the scientificity of our data collected.

From the charts, we could get that more than half of the people answered the questionnaires were young aged between 18 and 35. And the people between 35 and 50 also counted a crucial part. The information we got may insured the practicability and scientificity of our data collected.

We could notice that people received our questionnaires were mostly accepted a bachelor’s degree or not graduating students in college.

Due to the people received our questionnaire were mostly not graduating students in college, so the revenue people got, finding in this chart under 3,000 counted 52%. And the second most proportion was the people with the revenue between 3,000 and 6,000.

People from this chart mostly came from city, especially the second or third-tier cities, not downtown or countryside.

About 43% people thought that the most serious environmental problem around us was air pollutant. About 30% thought that the most serious problem was water pollution. So the most urgent two environmental pollutants people care about were the factors which were crucial to our life such as air and water.

Most people thought that furniture and paint are the main sources of formaldehyde. And rarely recognized that some cosmetics also release formaldehyde. Last but not least, nearly 10% people held the idea that, formaldehyde can be released by chemical carpet, automobile exhausts and burnt gas.

About 29% people recognized that formaldehyde might lead to cancer to people. 24% considered the consequence of formaldehyde was chronic hazard. 18% thought that formaldehyde irritated skin and mucosa.

Most people preferred ventilation above all other choices. And the proportion reached 34%. Also they were fond of green plants and it counted 29%. Besides, 21% people chose activated carbon, 13% chose air purifier, rarely chose photocatalyst, which might due to the unawareness of photocatalyst in my opinion.

People who did not choose plants to absorb formaldehyde was mainly because of the low absorbing efficiency. Also the troublesome of cultivating a plant also counted a lot.

About 81% people accepted the plant designed by the synthetic biology. And 15% people accentuated that they minded accepting this manmade plant. What couldn't be ignorable was that there were still 4% people could not accept the plant.

37% people believed that synthetic biology or genetic biology could be applied in medical science such as synthetic insulin and vaccine. 29% believed that hybrid rice was also one of the application of synthetic biology, and this implied that about 29% people cannot figure out synthetic biology ‘cause hybrid biology was not the application of synthetic biology, and the choice displayed here was just a barricade we made to distinguish the people knew synthetic biology or not.

34% people believed that synthetic biology or genetic biology could play a role in high yield of rice. 33% believed that it counted a lot in cutting the cost of drugs. 30% held the idea that it did a lot in promoting the environment. And only 3% people did not notice the effect made by synthetic biology.

About 39% people cared the biosafety of the plant made by synthetic biology, and about 29% paid attention to the efficiency of absorbing formaldehyde.

About 94% (77% plus 17%) people were in favor of our project in synthesizing a plant absorbing formaldehyde largely. Only about 4% people held the idea that they cared little about this project for the project had no business with them and 2% people did not back our project due to the potential hazard of synthetic biology.

When buying the products to absorb formaldehyde, people cared more about biosafety (47%) and the efficiency (32%). About 17% people cared about the price and 4% cared about the portability of the product.

When buying the products of absorbing formaldehyde, people prefered to supermarket (58%) and online shopping (26%) than roadside market or stalls.

There is more analysis of our questionaire,which contains more details of our analysis.
