But why isn't Chatham on the list, barely a mile away?


)I think it must be with the wind direction. From the West you get London. From the East you get the Dutch coast. From the North you get more industrial shit and from the south you get Saharan sandIf our prevailing winds are from the west - hence the east end of towns and cities typically being the poorer areas, ie down wind of factories etc - then I'm not sure how we get pollution from the Dutch coast.

From memory, I heard something about the direction of prevailing winds mean we get a lot of both London's pollution, and the Dutch coasts pollution blown our way. It would make sense given Thurrock also is high up on the list.

Its the untreated sewage thats the problem
Plenty of that on this forum. (Winking emoticon thingy)
