title: Contamination of human milk with chlorinated pesticides in Guatemala and in El Salvador.
abstract: In Central America huge amounts of persistent organochlorine pesticides are being used. This paper presents data on organochlorine residues in human milk. The samples studied were collected from areas with different spraying patterns. The results show very high contamination rates with organochlorine pesticides, especially with DDT. The highest levels were found in cotton-growing areas. Compared with residue levels in areas where cotton is not grown the difference was found to be statistically significant. Many of the quoted values are among the highest reported for the Western World. However, very high residue levels were also found even in Guatemala City, suggesting that other than agricultural uses of pesticides are important contamination sources. It is believed that these high levels of pesticide residues in human milk reflect a high contamination among the population in general.
