A PICTURE'S WORTH A
show cross section of a normal bluefish gill and a
bluefish gill after malathion exposure. Exposure was to
malathion at levels of levels which have previously been
found to occur in the environment at .05 mg/liter
Research conducted by the Department of Biological
Sciences, Kent State University, Ohio
Photograph of a healthy bluefish gill.
Section shows tips of what are called the primary filaments.
These filaments transfer oxygen from the water to the
PHOTOGRAPHS FROM THE
BULLETIN OF ENVIRONMENTAL CONTAMINATION TOXICOLOGY,
Photograph of the same area of bluefish gill as seen in
the left picture but 24 hours after the fish was placed
in a tank containing low levels of malathion (.05
mg/liter). Cross section shows tips of what is called the
primary filament. Note massive degeneration of filament.
This reduces oxygen levels to the fish.- both left and
right photographs were of the same area in the fish and
of the same magnification. Reseachers state not all fish
are this affected, but bluefish show heightened vulnerability
and bluefish are a popular food a game fish.
Protection Commission (EPC)
on water malathion levels
provided by Eric Lesnett 7/10
Maximum level of malathion allowed in
our waters - .1 ppb (parts per billion)
Highest level found by Environmental
Protection Commsion - 50.1 ppb
(This is 501 times higher than the maximum allowable
One of the highly toxic break-down
products of malathion is malaoxon
Present technology of the EPC can only
determine of malaoxon is present.
They are currently unable to give an "amount"
of malaoxon present
They can determine if malaoxon is present only if it is
above .5 ppb
If you see fish or wildlife kills please call Eric
