There is a dispute going on in one of the cities (which will remain nameless for this question, so as not to get political) on the Mediterranean about the following: there are about 120 thousand tonnes of ammonia imported by ship to this city every year (mostly for the production of fertilizer), with a shipment of 10,000 tonnes once a month, docking at this city's port to unload the cargo to the storage facility. The ship carries ammonia to other countries as well, each shipment containing 16,700 tons of liquid ammonia as it comes to this city's ports. The storage facilities have been designed with extra safeguards against earthquakes, small rockets and everything except a direct hit with a large rocket. The problem is that this city is a target for such rockets; the ship would also be in range of the rockets. So people are worried, but the engineers say that the danger is not as much as the press claims. Anyway, it is clearly a danger for the people of the coastal city if there is a direct hit on the tanks, especially around the port, but my question is not about that. Rather, there is the question as to what happens if one or more of the tanks on the ship are hit and its 3,340 tonnes of liquid ammonia spill into the Mediterranean near the city. What would be the resulting danger to the humans of the city, and the marine life?
