Which type of contaminants can be toxic to the reproductive systems of workers during certain construction activities?

Lead and asbestos are both well-documented hazardous substances that can pose significant risks to workers' reproductive health during construction activities.

Lead exposure is particularly concerning because it has been associated with reduced fertility, miscarriage, and developmental issues in offspring. Construction workers may encounter lead through various sources, such as old paint, pipes, and contaminated soil, especially in renovations or demolitions of older buildings. The absorption of lead into the body can lead to systemic toxicity, adversely affecting both male and female reproductive systems.

Asbestos is primarily known for its carcinogenic properties and its link to respiratory diseases, but it has also been implicated in reproductive health concerns. Workers exposed to asbestos may face risks of infertility, tribulations during pregnancy, and issues related to fetal development due to the toxic nature of asbestos fibers.

While heavy metals, pesticides, and solvents can also affect reproductive health, they are not as directly associated with construction activities in the same way that lead and asbestos are. Therefore, the specific mention of lead and asbestos highlights their unique and severe impact on reproductive health in the context of construction work, making this choice the most relevant in addressing the question posed.
