DDT is still used in many parts of the world, including Africa. But misquitoes have developed strong resistance to it, making it far less effective than it was just several decades ago.
To complicate matters further, in order for a DDT program to be effective, it has to virtually blanket a whole area, which increases human exposure to the toxins. If people do not want DDT sprayed on their property, the effectiveness of the whole program for a targeted area can be jeopardized
The chemical is quickly absorbed into the animal population and becomes abundant in human food supply.
it is not harmless to humans or animals. DDT can cause major hormone disruption, birth defects, miscarriges, and other reproductive issues in people. There is strong evidence linking it to some cancers.
Not really. DDT is still effective in Africa. As for cancer, toxicity = dosage.
Links, please?
...and stronger evidence linking the LACK of it to malaria, which also happens to be (unlike cancer, if you didn't notice) CONTAGIOUS.
Cheers!
