One in four chimpanzees and many other monkeys in Kibale National Park located in Uganda, born with serious mutations. Local scientists have discovered that some of the primates, reduced in size or even absent nostril, the other much deformed face, no third finger and so on. The reason for the mass of the birth of mutants experts believe pesticides, which local farmers allegedly used in the bypass Stockholm Convention.
Reportedly until 2014 primates with congenital deformities in the Park are extremely rare, but recently their number is increasing at an alarming rate. In particular, it has affected chimpanzees and baboons among them, the number of individuals with serious and significant genetic variance reached 25 and 17 percent, respectively. This trend has attracted the attention of scientists in Uganda and their counterparts from France, Canada and the United States.
Experts have examined soil samples, as well as seeds, plants in the Park, and is inhabited by fish. To obtain relevant information about the monkeys, the researchers were not able — direct interaction with primates is prohibited by the rules of the Park. The analysis showed that soil and, as a consequence, the inhabitants of the national Park poisoned the eight kinds of pesticides we are talking about glyphosate, dimethoate, MANCOZEB, metalaxyl, profenofos, chlorpyrifos, cypermethrin and 2,4-D amine. The average level of these pesticides in soil and seeds was much higher than the recommended limits. In one of the farms near the Park was also found illegal in the US since 1970-ies of DDT.
His research scientists published in the journal Science of The Total Environment. Biologists call more closely monitor the use of pesticides, especially banned because of people they hardly represent a smaller risk than for monkeys.
