Day 4 in Australia

Today started off with an unexpected but brief rain shower. But soon after that, Wife and I had a magical experience: we heard a bird making a racket outside so I went to the back door, where I was somewhat stunned to see that the noise was a common myna apparently just alerting me to the fact that there was a laughing kookaburra perched on the fence about 2 meters from me! The myna flew away immediately, having achieved its goal of getting me to come look; but the kookaburra, which really is a sizeable creature, hung out for another minute or so! I'd never seen one so close up. I felt a little like a Disney princess!

We ate an extended, early brunch before heading out to experience some public transit. First we took a bus to the station, then the brand-new driverless metro to the central business district of Sydney. That was pretty great. We got on at the end of the line, at the front of the train. So we could look out the front of the train. At another stop, a family boarded, so we got out of the way to let them stand at the very front; the children were very excited, which was really cute!

We then went over to the Art Gallery of New South Wales for the Cao Fei exhibition. Cao Fei is an artist from Guangzhou (from a family of artists); she was really involved in Second Life in the early days. This exhibition was a sort of immersive multimedia installation exploring themes of everyday life in China, technology, isolation, connection, industrialism, urban planning. There were a number of videos; the ones I watched were mostly depictions of industrial settings (including everyday physical labor) juxtaposed with humans trying to connect with one another or with their dreams, making them slightly surreal. Some of the videos had dance in them. My favorite section was a quieter area inside a "house", which was about the artist's sister Cao Xiaoyun, who was also an artist and had immigrated to Sydney. Some of her colored pencil-on-paper artworks were displayed (very different from Cao Fei's work!), and there was a living room with a TV showing a video about her, including her childhood, her art, her experience as an immigrant in Australia, and her death a couple years ago from cancer. My second-favorite part of the exhibition was a modified "ball pit" consisting of medium-sized foam cubes instead of balls, which was very difficult to move around, making me giggle a lot. I couldn't get Wife or SIL to join me in it, but it was a delight.

Afterwards we had a drink and a snack at MOD. Dining, the bar in that section of the museum. It included an exquisite Crispy Eggplant dish. We left just as another rain shower was ending, and it was very humid. After a bit of a wander in the central business district, we took the train back to a neighborhood near the house and went out for dinner before heading home. The wind had apparently gotten rather intense, as we saw a lot of downed tree branches littering the streets.

Other birds spotted today (without binoculars) included the ubiquitous bin chickens, Australian ravens, Australian magpies, and a sulphur-crested cockatoo.

In vitro bioaccessibility and health risk assessment of heavy metals in atmospheric particulate matters from three different functional areas of Shanghai, China

Publication date: 1 January 2018 Source:Science of The Total Environment, Volumes 610–611 Author(s): Huang Huang, Ying Jiang, Xiaoyun Xu, Xinde Cao The bioaccessibility and human health risks of heavy metals in PM2.5 and PM10 samples from three functional areas of Shanghai, China including a commercial area (CA), a residential area (RA), and an industrial area (IA), were investigated. Gamble’s solution and physiologically based extraction test were employed to simulate human respiratory and digestive system, respectively. Both PM2.5 and PM10 concentration in the three areas exceeded the guideline of WHO, and followed the order of IA>CA≈RA. Zinc and Pb were the most abundant metals with a concentration range of 0.19–0.44 and 0.05–0.42μgm−3, respectively. In respiratory system, heavy metal bioaccessibility for PM2.5 and PM10 varied within the range of 5.3%–71.4% and 4.8%–51.5%, respectively. Heavy metals in RA showed higher bioaccessibility than those in CA and IA in the respiratory system. In digestive system, heavy metal bioaccessibility for PM2.5 and PM10 reached 24.6%–90.9% and 28.5%–88.9% in the gastric phase and was reduced to 8.7%–85.5% and 8.5%–81.8% in the intestinal phase, respectively. The bioaccessibility of heavy metals in CA was highest among three areas in the digestive system. Based on the bioaccessibility analysis, the hazard quotient values of heavy metals in PMs via inhalation exposure were far below 1, the safe level, for both adults and children. However, potential risks via ingestion exposure resulted from Pb existed for children of three areas and for adults of RA as their hazard quotient values could reach up to 11. The obtained results indicated that the air quality in Shanghai need to be improved and the health risks to humans via ingestion exposure to atmospheric Pb must be considered.
