I wonder my writing is correct.
1. When the chemicals are absorbed into our skin, they build up in our body much more than when we eat them from foods . The materials can be remain stored in our body like heavy metal.
2.When we walk on the asphalt of rust spot, we can be exposed to radiation. Some asphalt has higher doses of radiation than the radiation doses of the a nuclear accident , such as the area in Fukushima, Japan
3. The Catholic Church has been in trouble understanding with science since the age of Galilei and I think these days the Church has conflicts and friction when looking at on biotechnology and genetic engineering.
Hope it helps- Ian
