Mercury can enter the food chain either from agricultural products or from seafood. It was widely used in agriculture, and at least 459 people are known to have died in Iraq after grain treated with a fungicide containing mercury was imported in 1971 and used to make flour (Greenwood, 1985). Those who showed the greatest effects were the children of women who had eaten contaminated bread during pregnancy. Human groups at risk include the millions of ASGM miners across the world, where mercury compounds are used in production. However, a far greater number of people whose main source of protein is fish or other marine creatures may be exposed to contamination (UNEP-WHO, 2008). The Food and Agriculture Organization says: “Just over 100 million tonnes of fish are eaten world-wide each year, providing two and a half billion people with at least 20% of their average per capita animal protein intake. This contribution is even more important in developing countries, especially small island states and in coastal regions, where frequently over 50% of people’s animal protein comes from fish. In some of the most food-insecure places – many parts of Asia and Africa, for instance – fish protein is absolutely essential, accounting for a large share of an already low level of animal protein consumption” (FAO, 2010). Mercury can seriously harm human health, and is a particular threat to the development of fetuses and young children. It affects humans in several ways. As vapour it is rapidly absorbed into the blood stream when inhaled. It damages the thyroid, kidneys, lungs, immune system, eyes, gums and skin. Neurological and behavioural disorders may be signs of mercury contamination, with symptoms including tremors, insomnia, memory loss, neuromuscular effects, headaches, and cognitive and motor dysfunction. Recent studies have also shown mercury to have cardiovascular effects (McKelvey and Oken, 2012). In the young it can cause neurological damage resulting in symptoms such as mental retardation, seizures, vision and hearing loss, delayed development, language disorders and memory loss.

When my elder son, my daughter, my younger son, his wife and three daughters all came round to my house last Sunday, my youngest grand-daughter thought I needed some Christmas decorations so she made this paper chain out of Christmas wrapping paper and her uncle helped her to put it up 😀
The Famous Chain, up close! We have been searching for this chain for ages and finally found it, just like that. Great Shot Darkday!
Five photos continuing our visit to the World Museum of Mining. This is the chain drive on the Fordson screw-propelled snow machine I posted recently.
i guess they took the whole leia chained up thing to the next level ...
some random pics i took while walking around. you can see my slideshow from the following url: vimeo.com/26991408
This is taken on the Chicago Riverwalk, about 200 ft South and down a flight of granite steps from my image "Skyline Bridge". The rotting wood and chains drew me in, but I stayed for the wealth of fine details...check out the wood grain and all the spiders in their webs!
Mamiya RZ67 Pro II & Sekor 110mm f/2.8 lens at 1/90th f/11 on Ilford FP4+ rated at EI80
Developed in HC110 dilution B (1+31), for 7:30 ("normal" for FP4+ @ 125 is 9:00) to offset the added exposure. Negative came out a touch thin, but this is a new film and new developer to me so I'll need to run tests.
Scanned on Epson V600 with Vuescan Professional, some minor adjustments to contrast and "clarity" along with some capture and output sharpening in Lightroom 5 and Photoshop CS5, but still very true to the contact print on grade 3.

Sometimes we are locked in or locked out for our own good. These are locks and chains on a gate on the Tarentum Bridge, 50 feet above the Allegheny River.
