The study of environmental toxicology investigates how different environmental pollutants affect living things. The recent years, this has been increasing acknowledgement of complex interactions that exit between environmental exposure and epigenetic mechanisms. The purpose of this abstract gives a brief synopsis how environmental toxicity affects epigenetics. Toxins found in the environment, such as pesticides, heavy metals, air pollutants, and endocrine-disrupting substances, can cause epigenetic changes that change the patterns of Histone alterations, non-coding RNA molecules, gene expression and DNA methylation are some of main epigenetic mechanisms impacted by environmental exposures. These changes may result in abnormal gene expression, which may pave the way for the emergence of a illnesses, including the cancer, neurological conditions, and problems with reproduction. Furthermore, the impacts of environmental exposures on epigenetics extend beyond the people who are directly exposed. It’s been established that environmental stressors can affect the epigenome of subsequent generations through a process known as transgenerational epigenetic inheritance. This occurrence emphasizes how crucial it is to comprehend how environmental toxicology effects population health over the long run. Finally, the interaction between environmental toxicology and epigenetics reveals a complicated web of interconnections impacting cellular responses to external stimuli. By comprehending these epigenetic changes, we may be able to develop targeted treatments to safeguard human health and get a deeper understanding of diseases brought on by environmental causes. Further study in this field is necessary to completely comprehend the intricacies of the environmental-epigenetic interface and apply this understanding to realistic public health initiatives.
