- Title: BRAZIL: MERCURY DUMPED IN SWAMP THREATENS LIVES OF THOUSANDS
-
- rio de janeiro, jul 17 (ips) -- thousands of people are exposed
- to kidney failure and even cancer, due to high levels of mercury
- pollution in a swamp in east central brazil which empties into a
- river shared by brazil, paraguay, bolivia, argentina and uruguay.
-
- a university study released here friday found fish with up to
- 2.5 milligrammes per kilogramme of muscular tissue and birds with
- as much as four milligrammes in the mato grosso swamp, from which
- the paraguay river obtains its water.
-
- the world health organization sets 0.5 milligrammes per
- kilogramme as the maximum acceptable limit, according to the
- study by luiz marques vieira, agronomist at the centre for
- agricultural research on the matto grosso swamp.
-
- vieira conducted close to 1,000 tests on fishes, birds,
- molluscs and sediment from the network of rivers and lagoons
- which form the swamp, a humid ecosystem with an area over 200
- square kilometres and an enormous zoological wealth.
-
- half of the tests showed mercury levels above the acceptable
- limit.
-
- vieira's study is part of a doctoral thesis done at the
- federal university of san carlos in the state of sao paulo.
-
- mercury is washed into the rivers when 'garimpeiros' (informal
- prospectors) use it to separate gold from surrounding material.
-
- the heavy metal sinks to the river beds, the feeding grounds
- of fish and molluscs, which in turn are eaten by birds and
- humans.
-
- until recently, pocone, an area close to the rio cuiaba in the
- state of mato grosso, was a major prospecting centre. informal
- gold mining has been prohibited in pocone, but enforcing the ban
- is a difficult task.
-
- the highest levels of mercury pollution have been registered
- in the cuiaba and in bento gomes river, which is also close to
- pocone.
-
- the waters of the mato grosso swamp run off sluggishly,
- because of the relative flatness of the area between matto
- grosso, bolivia, paraguay, argentina and uruguay through which
- they flow.
-
- in the state of mato grosso do sul, which borders on bolivia
- and paraguay, the study found mercury levels ten percent above
- the acceptable limit.
- ----
-
-
- vieira found that birds showed the highest levels of
- contamination because fish constitute an extremely high
- percentage of their diet.
-
- but in the region around the swamp, fish is also the main
- source of protein for a large section of the population and this
- has sparked fears that the health of many people may already have
- been irreparably impaired.
-
- mercury damages the kidneys and the central nervous system. it
- can also cause cancers and genetic modifications, according to
- doctors who have been conducting studies in this field.
-
- informal mining is done in the entire western and northern
- part of brazil. trade union sources say it employs close to one
- million people, most of whom use mercury to extract the gold.
