ザンビア再び【Zambia, again】

   I have been to Zambia, again. My first oversea trip of 2016 was this one. I traveled Zambia to talk about soil contamination, particularly lead (Pb). Well, I knew it but I realized that this issue is pretty complicated and hard to deal with. A city called Kabwe has a pre-mining area and there are a lot of mine residues piled up. We have to think about what we do with them. There are number of places where soil contamination is an issue and at all of the sites, things are pretty serious because we live on soils and we grow our foods on them. Our body can be heavily contaminated if our soils are contaminated, for sure. 
   There are a few methods known to fix the problem, for example, plants and some chemical materials can be used. We discussed which methods are potentially efficient and what sort of research has to be done to prove that. 
   I have to say that now I have so much to think about... By the way, milking experience in Zambia was such an awesome event for me because I just love cows.
