The monitoring of pesticides and alkylphenols in selected rivers in the state of Selan Jor, Malaysia

Alkylphenols and most pesticides, especially organochlorine pesticides are endocrine-disrupting chemicals and they usually mimic the female hormone, estrogen. Using these chemicals in our environment would eventually lead us to consume them somehow in the food web. Several rivers in the State of Sel...
