What are the Challenges in Establishing a Causal Link?
Establishing a causal relationship between chemical exposure and HL is challenging due to several factors:
Latency Period: There is often a long delay between exposure and disease onset, complicating the identification of causal agents. Multifactorial Etiology: HL's development is influenced by a combination of genetic, environmental, and lifestyle factors, making it difficult to isolate the impact of specific toxins. Variability in Exposure Levels: Individuals are exposed to varying amounts of chemicals, and measurement of these exposures can be imprecise.
