Which pesticide was associated with male infertility and alterations in the sex ratio of offspring in 1977?

  1. DDT

  2. DBCP

  3. TCDD

  4. Ethylene Dibromide

The correct answer is: DBCP

In 1977, research found that DBCP, also known as 1,2-Dibromo-3-chloropropane, was linked to male infertility and changes in the sex ratio of offspring. DDT (option A) is often associated with environmental and health issues, but was not specifically linked to male infertility and sex ratio alterations in 1977. TCDD (option C), also known as dioxin, is a highly toxic chemical, but it was not associated with male infertility and sex ratio changes in 1977. Ethylene dibromide (option D) is also a toxic chemical, but was not directly linked to male infertility and changes in sex ratio in 1977. Therefore, option B remains the correct answer.
