Virttaankangas säilytettävä tulevillekin sukupolville

Perulainen ystäväni dr. Arroyo kirjoitti minulle eilen.
HI HEINO
FIRST OF ALL, MAY YOU PLEASE CALL ME JUST NILTON?

YES, METHYLHg (MeHg) IS THE MOST POISONOUS OF ALL THE
Hg CHEMICAL SPECIES

AND THE CHLORALKALI PLANTS ARE A SOURCE OF METAL (OR
ELEMENTAL Hg), AS IT WAS IN MINAMATA BAY.

MeHg CAN ENTER TO THE FOOD CHAIN AND GOES THROUGH THE
LIVING MEMBRANES EASILY, CAUSING DAMAGE IN VARIOUS
ORGANIC TISSUES. AS YOU KNOW, THIS IS THE MOST
DANGEROUS OF ALL THE MERCURY SPECIES.

THE ELEMENTAL OR METAL Hg IS TRANSFORMED INTO ORGANIC
ONE (MeHg) BY ALL KIND OF BACTERIA CAPABLE TO PRODUCE
VITAMIN B12 (Pseudomonas spp, AS A MATTER OF FACT).
THE RATE OF THIS TRANSFORMATION DEPENDS ON THE
TEMPERATURE, AS ANY BIOLOGICAL ACTIVITY. SO, FIRST AN
EVALUATION OF THE MERCURY COMPOUNDS IN THIS RIVERS
SHOULD BE MANDATORY.

SECOND, OSMOSIS REVERSE (VERY EXPENSIVE) IS A SOLUTION
FOR ELIMINATION OF ALL HEAVY METALS, INCLUDING Hg
COMPOUNDS OF COURSE.

I´LL BE PLEASED TO KEEP IN TOUCH WITH YOU UPON YOUR
QUESTIONS, SO FEEL FREE OF SENDING YOUR CONCERNS.

SINCERELY YOURS, NILTON
